Project Managers Assessment Safety and Health Through January 31, 2018, WRPS Tank Operations Contract had worked 4,998,475 hours (358 days) without a Lost Time Workday Injury, and 1,104,044 hours (76 days) since the last Recordable case. The

  1. Project Manager’s Assessment (cont.) A-Farm Ventilation : Preparations began for placement of the A-Farm exhauster pad, including soliciting subcontractors to perform the work. The engineering design for A-Farm equipment removal and waste retrieval system installation was in progress. Fabrication of a proof-of-concept for duct isolation of A-Farm ventilation was completed. Retrieval Technology Development: • Volume Measure Tool - Five expressions of interest from potential vendors were received. Four of the five have potential to provide a laser in-tank volume measurement system that should meet the critical requirements. Engineering began developing a Design Specification for development of a working measuring tool that can be used in 4” risers. It is planned that the specification and statement of work (SOW) will be completed and su bmitted to Procurement no later than March 5, 2018. • Rotary Core Drilling Technology - Procurement actions for a subcontract change to complete the remaining tasks were completed. The analyses required to core drill one 6-foot diameter hole in an SST tank dome was completed. The development continued on the specification and SOW to design and build a tank dome coring system. The specification was completed on February 8, 2018, and the SOW was scheduled to complete by March 1, 2018. • Mechanical Waste Gathering Tools - WRPS engineering completed the final drafts of the SOW, specification and the mod traveler in mid-December 2017. The Request for Proposal is now anticipated to be issued by March 12, 2018. • Develop a Hard Heel Sampling Tool(s) for A/AX Tanks - The SOW and specification for a vendor to modify existing tools (the “Auger” and “Clamshell”) was being developed by engineering. • Mobile Gamma Scanner - Engineering identified a commercially available instrument that can withstand at or above 130o F. The vendor is still required to verify the scanner functions within required parameters with 120 feet of cable attached prior to final procurement actions. Tank Farm Projects SX Interim Barrier Construction : The SX Farm evapotranspiration basin liner was completed in late December. The anchor trench was backfilled and compacted. Excavation for the drainage lines revealed numerous legacy utility lines which were being evaluated for removal or capping by WRPS Engineering. The storm water collection system distribution piping was installed in the basin. The excavation for the southeast and southwest stormwater collection vaults has been completed. Excavation began for the north stormwater vault. The Bay separator, a long lead procurement, was received and the subcontractor excavated the area for placement of the vertical catch basin which separates solids from water. Backfill of the basin continues, utilizing 36 inches of native sandy loam soil for filtration. The subcontractor is awaiting final engineering resolution for removal and/or rerouting of the legacy utility lines uncovered during drain pipe trench and storm water vault excavation. The bids were received for Phase II Interim Barrier Asphalt Cap for the north and south sections of the SX Farm and awarded in early February. Single Shell Tank Integrity Visual Inspections : The SST visual inspections were completed at tanks SX-103 and SX-113 in late December, and at U-103 in early January. This brings the total of SST visual inspections to 9 out of the 12 scheduled for fiscal year 2018. It is anticipated the remaining three inspections will be completed well ahead of the baseline schedule during January and February 2018. Results of any findings will be included in the report by farm at the conclusion of visual inspections this spring. DNFSB Recommendation 2012 - SS Flow Instrumentation : The electrical installation has been completed at all six pits to support the safety significant flow instrumentation in AW Farm. The subcontractor crew completed construction acceptance testing during early February. Following the CAT in AW Farm the mechanical installation of safety significant flow instrumentation will commence in AY/AZ Farms (early February). January 2018 4

  2. Project Manager’s Assessment (cont.) DST Transfer Pump Replacements : The Tank Farms field crew lifted the AW-103 pump partially out of the pit in order to perform an exploratory flush. The pump and column flushed cleanly with no apparent blockages evident. Laser scan measurements will be taken with the pump back in place to assure proper fit of the newly fabricated jumper. One of the previously purchased spare pumps in storage will be used as a replacement with the newly fabricated jumper. The SS transfer system components purchased during FY17 and FY18 will be utilized for completing the jumper fabrication and installation. Tank Farm Automation Upgrades Part II : The Tank Farm Automation subcontractor completed the fabrication of new freeze protection panels. The panels have been factory tested at the vendor and will be shipped in February. The new antennas were received from the fabricator and will replace the deficient ones in the field. 242-A Reboiler : Fabrication of the new spare re-boiler for the 242-A Evaporator continued with tube bundle assembly and completion of nozzle welds. Shell body fabrication continued at the vendor with completion of the fit/welding of vapor belt, impingement plate and circumference seams 1 and 2. Head Space & Stack Sampling : Farm setup of test jig was completed for BY Farm comparison head space sampling. Sampling will be used to validate the future use of the cartridge sampling unit to carry out future head space samples. Validating the cartridge unit for future use will greatly facilitate future sampling, driving both schedule and cost efficiencies. Comparison sampling in BY Farm will be executed in February, followed by a powered air purifying respirator cartridge test in BY Farm. Comprehensive Vapors Action Plan Workers who participated in field trials noted that the use of an air-line breathing system has many benefits, including increased mobility and lighter equipment to load. The field evaluations found a few obstacles to the equipment such as managing the hose, the hose length limiting users in certain areas and possible safety issues with hoses on the ground while multiple workers are moving throughout an area. Overall, the selective use (stationary activities within farms, wire terminations, select riser pit activities, etc.) of air-line breathing systems would be beneficial and improve overall task efficiencies. The AZ Farm Exhauster passed the declaration of readiness for both POR-126 and POR-127, and is now in full-time operation. Nucon Thermal Oxidation Vapor Abatement Unit : The development of the engineering-scale testing was on-going, to include preparing the technology maturation plan, transferring the Ultra-Violet Fourier transform infrared spectroscopy, and procuring documentation to repair and modify the unit to operate at 180ºC. Closure and Interim Measures The design of the SX Expansion Barrier was nearing completion. Review of the 90% design was completed. Ecology unofficially approved the design for construction, based on their review of the 60% and 90% design packages. Ecology approval will be documented through an agreement by Ecology and ORP Project Managers. Production Operations The stack monitors functional requirements document was completed and submitted for formal check and review. This will provide basis for vapors monitoring for discharges from DST farms. The Electronic Routing Board design was completed. The Electronic Routing Board is an electronic version of the paper routing board display in the Central Shift Office. The P&CS EV Team completed the replacement of a vacuum sample pump in AW primary B-Train Exhauster. January 2018 5

  3. Project Manager’s Assessment (cont.) Tank Farm Automation : MSA and Process and Control System Engineering (P&CS) Engineers replaced Meru wireless access point with a Prosoft access point at AN Farm and configured Prosoft radios in preparation for MSA upgrade activities, which are to be performed in the near future. This infrastructure change to support the Tank Farm Automation project has shown improved reliability and systems performance over the older access points. The order for equipment to replace the remaining farm access points was placed. Engineering Process and Control System (P&CS) engineers: • Supported FAT at the vendor’s facility for the six temperature monitoring/freeze protection panels to be installed at AW Farm. This was following a modification to add local indicators to panels, and to ensure proper operation using Tank Farm Safety Programmable System development controller. Field installation is scheduled before • Identified functional requirements needed in order to provide electronic rounds/surveillance support for normal system monitoring tasks performed. The proposed plan would be to utilize the electronic rounds application to document performed surveillances. One System & Chief Technology Office A deep dive review of the Tank Side Cesium Removal (TSCR) Demonstration Project was conducted with representatives from DOE-HQ and ORP senior management to discuss technical, permitting, and safety analysis requirements. The review resulted in a number of positive recommendations regarding permitting and safety documentation strategies. A Joint Management Review Session was also conducted to review the status and integration of the Low Activity Waste (LAW) Vitrification Facility Project and the WRPS TSCR, Tank Farm Upgrades, and LAWPS. Additional January 2018 Items of Note • Hanford contractor CH2M Hill Plateau Remediation Company announced an expanded work control zone around the Plutonium Finishing Plant due to specks of low-level contamination being detected outside the original access control boundary. WRPS is currently evaluating the potential impacts of the expanded work control zone on scheduled WRPS activities and work. • WRPS Contracts submitted a change proposal to ORP for the Technology Demonstration of the TSCR. The TSCR system will be first of its kind on the Hanford site for an at-tank cesium treatment of tank supernatant. The resulting treated tank waste will then be used as LAW feed to the Waste Treatment Plan in support of LAW Vitrification Facility hot commissioning and early operations. This proposal is the first of three integrated waste feed delivery change proposals directed by ORP due to the change in direction driven by the external review panel. January 2018 6

  16. Small Business Reporting Through January 2018, WRPS has awarded a total of $1,689M in subcontracts, of which $1,098M (65.0%) CTD is attributed to small businesses. The CTD awards to small businesses exceeds the 58.2% small business subcontracting goal. WRPS will continue to promote small business subcontracting by setting aside procurement actions for small businesses when appropriate, as well as by reaching out to new small businesses in furtherance of this objective. In January of 2018, WRPS did 4.32% with Small Veteran Owned Business on a goal of 1.3%. In order to improve our overall small business goal in the rest of the socio-economic categories the Small Business Program Manager (SBPM) has been utilizing SAM.GOV and the Small Business Dynamic Search with solicitations/EOI to reach out to businesses who fall into those socio-economic categories to look at our solicitations and sending them items to bid on. As you can read from opening the attached spreadsheet, some numbers are negative because we have been closing out subcontracts/de-scoping. In January 2018, the SBPM attended a number of outreach events in the community to continue to search and network with the small businesses in the Tri- Cities community. The SBPM spoke at the Women in Business Conference in Kennewick, WA in front of over 400 attendees, as this year is the first year in 7 years that this event has sold out. WRPS was once again the prime sponsor for this event. The SBPM was able to meet a few WOSB at the conference that might be interested in doing work with WRPS. The SBPM is still working to plan and host a mini Meet the Buyer focusing on construction resources so WRPS has some more small business construction vendors that they can utilize. The Small Business Council is also continuing to plan Bridging Partnerships which is being held in April 2018 at the Three Rivers Convention Center in Kennewick, WA. January 2018 19

  34. Tank Farm Projects CTD Schedule Variances CTD SV January 2018 (-$8,600k) 5.1.1.3.8 Core & Grab Sampling (-$303k) Cause: D elay in obtaining the AY-102 grab sample (-$147k) and a delay in the procurement of sampling equipment (-$157k).The AY-102 sample is dependent upon a determination on SCBA or APR requirements to perform the work. Also higher priority sampling in support of C-105 retrieval in September contributed to the delay. The purchase of sampling equipment in September has been delayed due to engineering evaluation of functions and requirements for the equipment, as well as, examining currently available equipment for ease in procurement. Impact: This variance does not impact any other control accounts. Sampling schedule variance will continue until higher priority sampling has been completed and a determination on SCBA or APR requirements has been made. Equipment schedule variance will continue through second quarter of FY18 due to engineering evaluation and long lead time for procurement, however the project has sufficient equipment to execute current scope of work. Corrective Action: The schedule variance for AY-102 sample will be recovered in the coming months once higher priority sampling has been completed and a determination on SCBA or APR requirements has been made (Projected March). The sampling equipment variance will be recovered once equipment has been ordered and received (Projected March). 5.1.1.5.20 DST Integrity Improvement Plan (-$686k) Cause: 1) Delay in delivery, on site testing and training for the Robotic Crawler designed and fabricated by Kurion. 2) The contract for Flash Thermography contract was not placed. A feasibility study was done to ensure the final product could be utilized to meet the scopes intent. It was determined that the Flash Thermography technology could not properly be deployed in the field so pursuing a contract was no longer viable. With the scopes intent not able to be met and the project on hold. The Preliminary & Final Design, as well as Fabrication, Test & Delivery activities are now behind schedule. Flash thermography scope will no longer be performed and has been logged to go off contract. 3) Delay experienced awaiting the specification document from PNNL which delays procurement. Impact: 1) Robotic crawler deliver scheduled late February 2018; full recovery with performance demonstration July/August 2018. 2) Flash Thermography scope will be deleted in future BCR.3) Guided Wave field deployment and final report are projected as carryover for FY19. Corrective Action : 1) No corrective action. 2) Flash thermography scope balance has been logged as part of the scopes to go off contract. Upon receipt of formal deletion modification the baseline will be updated to reflect removal. 3) The Guided Wave deployment and final report have been logged for deferral to FY19. 5.1.1.5.27 DST Ultrasonic Testing FY17 (-$1,191k) Cause: Delayed start of Ultrasonic Testing (UT) at AZ-101, AY-101, and the SY Farm floor scans. The delay was originally caused by the lack of necessary support labor resources required to perform the UT Scans at AN-106. These labor resources were performing UT scans in the 242 Evaporator Room under WBS 5.1.1.5.11. After the AN-106 UT field work kicked off in December, additional delays were incurred due to poor weather conditions. The Hanford site was closed, delayed or released early a number of times in December & January. These weather related delays caused the unfavorable schedule variance to grow and subsequently delay the start of UT scans at AZ-101. UT field work at AZ-101 was again delayed due to the PUREX tunnel collapse that occurred on May 9th, 2017. Three working days were lost as crews weren’t allowed into the farm (May 9th -11th). On May 12th, the UT crew was allowed back into the farm to retrieve the two crawlers that had been left on the Double Shell Tank (DST) annulus wall since the take cover was initiated on May 9th. The extended period of time each crawler spent on the annulus wall, caused them to receive high doses of radiation. This caused some electrical components to fail and require 2 additional working days to repair (May 15th-16th). On May 18th, UT field work at AZ-101 was shut down due to the unexpected discovery of contamination in the tank annulus. This discovery resulted in a stop work at AZ- 101 as an event investigation was implemented to review what took place and develop any necessary corrective actions. During FY18 additional delays due to farm ventilation issues and SCBA mask issues, have continued to impede performance although AY-101 UT is currently underway. Impact: The delayed start, inclement weather, PUREX tunnel collapse, and contamination event have impacted the schedule to perform Ultrasonic Testing (UT) on six Double Shell Tanks (DST) in FY17. The field work for AN-106 finished in March but had already slipped 47 days. The three SY floor scans finished 34 days behind schedule and the field work at AZ-101 & AY-101 is now being performed during FY18 as carryover. The UT scope at AY-01 is forecast to complete in April 2018 and AZ-101 July 2018. Corrective Action: Continue to work with the Work Area Manager and Production Controls to ensure the necessary resources are available to complete the UT field work at AY-101 and AY-101. 5.1.1.5.33 Simulant Valve Testing (-$399k) Cause: Delays in testing the PBM metal seated valves and Flowserve Mach 1 valves ($98.1k). During assembly of the Flowserve Mach-1 valves, it was discovered that soft-component seals for the test valves were incompatible. In result, testing was delayed while WRPS and PNNL worked to identify the cause and appropriate replacement seals. During reassembly of the PBM metal seated valves, it was discovered that the vendor procedure did not adequately address reassembly of the valves in a configuration that is leak tight. To resolve the issue, WRPS and PNNL revised the vendor procedure to support a leak tight configuration and submitted to the vendor for concurrence. As a result testing was delayed while WRPS and PNNL worked to identify the correct configuration and revise the vendor procedure for reassembly. The delays in testing of the Flowserve Mach-1 and PBM metal seated valves have also delayed teardown, ($50.5k), and completion of the final test report, ($249.3k). Impact: The issues associated with the Flowserve Mach-1 and PBM metal seated valves have delayed the start of testing so that it is no longer being performed in parallel with the McCanna valves. This has also delayed completion of the contract to November FY19. Corrective Action: 1) Revise the vendor procedure to adequately address reassembly of the valves in a configuration that is leak tight (February2018). 2) Have vendor obtain new Tefzel seals that will be compatible with the valves for testing. The valves are expected to be delivered to PNNL no later than 2/5/18. January 2018 37

  35. Tank Farm Projects CTD Schedule Variances CTD SV January 2018 (-$8,600k) 5.1.1.5.36 DST Structural AOR to Support Tank Level Rise (-$557k) Cause: 1) Delayed contract award and start, 2) resource availability issues, and 3) additional seismic modeling requirements being identified. 1) This scope is primarily based on a large contract with Pacific Northwest National Laboratories (PNNL). The placing of this contract was delayed as engineering resources weren't available to develop and review a technically accurate statement of work. This resulted in a two month delay in PNNL starting their support. 2) PNNL experienced resource availability issues related to a delay in placing their subcontract with Becht Nuclear Services to support performance of the Seismic modeling. The contract was delayed as Becht was no longer on PNNL's Evaluated Suppliers List (ESL) and needed to have their Quality Assurance (QA) program reevaluated. WRPS also experienced delays in having the Evaluation Criteria Document reviewed. The contracted expert reviewer was out of the country and unavailable. These resource related delays resulted in an additional two month slip. 3) Recommendations from the expert reviewer led to an additional seismic modeling approach being implemented into the overall Analysis of Record. This has delayed the completion of a final seismic modeling approach and resulted in an additional four month schedule slip . Impact: Overall, the project is projecting to finish 9 months behind schedule (September 2018). Corrective Action: No corrective actions have been identified at this time. The project is planning to finish nine months behind schedule (September 2018). 5.1.4.1.18 DST In-Pit Heating (-$831k) Cause: Field work activities have been delayed by the completion in final design. The delay resulted from reworking the installation design needed due to change in requirement to burying the conduit instead of running flex conduit under yellow jacket covering from the mini power zone to the cover block. Procurement of heaters needed for FY18 field installation have been delayed by 5 months due to the procurement resources working on higher company priority procurements. Originally the materials were planned to be delivered in August, the current delivery date is February 2018. Impact: Projects affected if DST In-Pit Heating is not completed are as follows: TF Automation Part 2 due to the need for the project to install the AN01A and AN06A temperature monitoring trees and update associated design media to account for the utilization of the upgrades trees from both projects and vapor controls by limiting the use of operators and redeploying these resources to other projects would not occur (projects such as DST transfers). Corrective Action: Project has worked with procurement to insure the material request is awarded and heater delivery is scheduled the second quarter of FY2018. 5.1.4.1.48 DNFSB Recommendation 2012 2-2 thru 2-4 (-$303k) Cause: Delay in completion of construction acceptance testing (CAT) in AW farm as well as the AY/AZ design work. The CAT was originally planned for completion during fiscal January 2018, however, a companywide mask stop work delayed the completion of the installation until the end of the fiscal month January 2018 which pushed the CAT testing out into fiscal month February 2018 Impact: The total of float for DNSFB 2012-2 Action 2-3 the total float 1 day. The total of float for DNSFB 2012-2 Action 2-2 gained by 11 days making the total float 11 days as a result of the AW Farm performance recovery during the period. Corrective Action: The project is planning to overtime to complete the CAT. 5.1.4.1.64 DST Transfer Pump Replacements (-$652k) Cause: WRPS reprioritization of the pump replacement projects. The AZ-102 pump replacement mobilization for pump removal is now the successor to the AW-103 demobilization activities. In November 2017, the AW-103 project realized a risk AW103-008-R, pump plugged during flushing. This realized risk prioritized and accelerated the schedule for AW-103 to mobilize and perform pump flush activities. In addition, as a result of this realignment, mobilization and field work activities associated with the AZ-102 pump replacement project have been further delayed. AZ-102 mobilization is scheduled for mid-February. Impact: Due to the acceleration of AW-103 pump replacement, AZ-102 field mobilization has been delayed until after demobilization activities have completed for AW-103. However, the bottle change location has started at AZ-102 to prepare for mobilization and along with schedule recovery noted above the project demonstrated positive recovery in the current month. Corrective Action: Full schedule recovery for the design activities is planned upon the release of the AZ-102 As-Built ECN in March 2018 and full schedule recovery is anticipated for the fiscal year as current projections are demonstrating plant forces availability to complete execution.

  36. Tank Farm Projects CTD Schedule Variances CTD SV January 2018 (-$8,600k) 5.1.4.1.85 242-A Spare Re-boiler (-$499k) Cause: Delayed receipt of the spare 242-A re-boiler currently undergoing fabrication. The re-boiler was originally anticipated to be received in September FY17; however, during the design review it was determined that an additional Finite Element Analysis (FEA) was needed to address nozzle loads of the vessel. Impact: The additional analysis has delayed the receipt of the spare re-boiler until April FY18 and will incur a negative schedule variance that will persist until receipt. Corrective Action: The additional analysis is complete and has been approved to allow the vendor to proceed with fabrication. 5.1.4.1.91 242-A Evaporator Fire Alarm Panel Upgrades (-$772k) Cause: Delay of installation as a result of an issue with original engineering change notice (ECN) needed for the installation. The subcontractor is currently working on a new fire alarm system ECN and project completion date is now March 31st. Impact: Currently no impact to any evaporator campaign and field work will be executed within available facility windows. Corrective Action: Project is working with contractor on schedule recovery plan. 5.1.4.1.94 Fire Alarm System Upgrades – 2704-HV & 222-S (-$375k) Cause: Two month delay in award of design subcontract as result of bidders’ requests to extend proposal period to find specialized fire systems subcontractor for sub -tier. Impact: No impact to other projects or evaporator campaigns. Corrective Action: Subcontractor is on board and forecasts finish April 2018. January 2018 39

The variance is caused by upfront design delays following a late contract award as upfront scoping agreements took longer than anticipated for east area farms. An Engineering change request was required for re-work of failed PA system batteries. Vendor has had insufficient resources to provide for field work activities. Work is on-going in AP & C farm and is expected to be completed by 1/30/18. Corrective Action : The Material request for the remaining speaker poles, mounts, and batteries was completed on 12/5/18 and is expected to arrive on 2/15/18. Reader boards have been ordered and are expected to arrive after a 12 week lead time on 3/5/18. 5.1.5.11.60 – CVAP 222-S Laboratory Upgrades (-$599k) 5.1.5.11.9 – Head Space & Stack Sampling ($1,163k) Cause : The cumulative to date schedule variance is primarily due to the delayed procurement of the GC Cause: The favorable contract-to-date variance is due to usage efficiencies attributed to field labor support mass spectrometer. Subcontracting issues related to the procurement of the equipment have been resolved usage and diminished Crane & Rigging support to Head Space & Exhaust Stack Sampling in FY16. and the procurement contract has been issued with an anticipated receipt date of February. Installation and renovation activities will follow and are expected to begin in March. After carrying out initial samples, it was determined that 1) Less than anticipated NCO's, IHT's, HPT's, and plant engineers are required to complete samples, 2) samples can be completed with less than originally Corrective Action: No corrective actions planned. Installation & renovation activities are expected to planned Crane & Rigging support because the riser caps being accessed to perform sampling can be conclude in August removed manually rather than requiring Crane & Rigging support as was initially planned, and 3) exhaust stack samples are able to be completed in tandem with head space samples utilizing the same crew. Corrective Action: No corrective action required. Cost variance is favorable and project anticipates continued efficiencies carrying out future samples. Anticipated savings are reflected in the EAC.

The activity delays were a result from stacks. multiple revisions of design development due to unforeseen complications and issues regarding placement of VMDS equipment. Corrective Action: There are no corrective actions planned at the current time. The unfavorable variance is not anticipated to be fully recovered for design effort. 2)Delays in developing the enhanced auto sampler unit. Final design and procurement of necessary materials to develop the auto sampler required UV-DOAS equipment specifications which were unavailable until early October FY18 after stack monitor designs for AN, AW, and AZ were completed. Corrective Action : 1) Final work packages are being executed and closed out to finalize VMDS pilot testing technical subcontract support. Completion of these activities is anticipated in January FY17. 2) UV-DOAS equipment specifications have been received by vendor and being incorporated into the design of the enhanced auto sampler unit. WRPS engineering are working closely with vendor to ensure proper design inputs and materials are ordered. Procurements will be done in parallel and several sub-components of the enhanced auto sampler will be FAT tested on an interim basis prior to a final integrated FAT in hopes to resolve any potential issues early on in the process. 5.1.5.11.56 – Vapor Monitoring & Detection System Upgrades (-$2,078k) 5.1.5.11.33 – 33-RM6 New Vapor Detection Technology ($842k) Cause : The cumulative to date unfavorable variance is driven by Cause : The cumulative to date favorable cost variance is attributed to the following: 1) result of conversion of planned field installation and testing resources from plant forces direct labor to construction forces 1)Delayed receipt of fence-line monitoring equipment. Upfront procurement process and contract award to subcontract and 2) the utilization of less than anticipated support for the amount of work accomplished in vendor was delayed to allow further time to finalize specifications for the equipment.

  66. LAWPS CTD Variances Schedule 5.5.4.2.1 P - LAWPS - Design - Project Support (PS) -$509k Cause: On October 23, 2017 the External Expert Review of the Low-Activity Waste Pretreatment System (LAWPS) Project document was released, which endorsed an optimized LAWPS facility that would vary significantly from the previous LAWPS design. Following the External Expert Review, on November 16, 2017 WRPS received Letter 17-TF-0096 - CONTRACT NUMBER DE-AC27-08RV14800 - Direction to Suspend Selected Low Activity Waste Pretreatment System Design and Testing Activities, providing formal direction from the U.S. Department of Energy, Office of River Protection (DOE-ORP) to de-scope items associated with the previous LAWPS design. As a result, on November 29, 2017, WRPS terminated the subcontract previously established for Seismic Testing of the LAWPS Jumper Connectors, -$345k. This scope will reside in the project's PMB until a BCR is implemented to remove the associated remaining BCWS. Until then, unfavorable schedule variances will continue to be realized. In addition, the CD-3A design package review and approval activity and IQRPE planning work has also been placed on hold as part of the replan, -$163k. Impact: The project team is in the planning stages of an optimized LAWPS design. It is anticipated that the current remaining baseline activities will be replaced by a revised plan. In the interim, schedule variances will continue to be realized as the Stop Work remains in effect. Corrective Action: No corrective actions planned. 5.5.6.2.1 P - LAWPS - Design Safety Analysis -$304k Cause: The CTD SV is due to Flammable Gas Hazard Analysis of LAWPS Piping and Vessels. The Procurement process experienced a delay in the award of the subcontract due to clarifying scope with the subcontractor prior to award. In addition, the initial analysis was performed with assumed gas volumes and max postulated pressures which provided overly conservative results. WRPS then calculated actual pressures and gas volumes and requested a re-run of the analysis, -$255k. Impact: The project team is in the planning stages of an optimized LAWPS design. It is anticipated that the current remaining baseline activities will be replaced by a revised plan. In the interim, schedule variances will continue to be realized as the Stop Work remains in effect. Corrective Action: No corrective actions planned. January 2018 69

  67. LAWPS CTD Variances Schedule 5.5.7.1.2 P - LAWPS - Tech Mature. Integrated Scale Test -$485k Cause: The CTD SV is due to delays in Gas Retention and Release Testing and AECOM 1/9 Scale Testing (-$438k). Commencement of the revised Gas Retention and Release Testing was initially delayed due to availability of vendor (PNNL) resources. Although testing has now started, the vendor is experiencing longer than anticipated durations due to the late start and continuing resource limitations (-$114k). AECOM CFF foulant testing activities have been placed on hold pending formal direction from DOE regarding the LAWPS re-scoping effort. This activity will contribute to the negative SV in this account until this work scope is removed from the baseline (-$323k). Impact: The PNNL and AECOM testing schedules do not currently have any CTD schedule impacts as the LAWPS design is progressing with preliminary data received from test results. Corrective Action: WRPS management will meet with the A/E responsible for the Preliminary Design to assess testing impacts from the GRS/Vented IX Column and other design changes. Once the impacts are determined, the project team will determine whether it is necessary to accelerate / recover schedule for the testing. 5.5.8.2.1 P - LAWPS - Design System Integration -$2,690k Cause: On October 23, 2017 the External Expert Review of the Low-Activity Waste Pretreatment System (LAWPS) Project document was released, which endorsed an optimized LAWPS facility that would vary significantly from the previous LAWPS design. Following the External Expert Review, on November 16, 2017 WRPS received Letter 17-TF-0096 - CONTRACT NUMBER DE-AC27-08RV14800 - Direction to Suspend Selected Low Activity Waste Pretreatment System Design and Testing Activities, providing formal direction from the U.S. Department of Energy, Office of River Protection (DOE-ORP) to de-scope items associated with the previous LAWPS design. As a result, on November 20, 2017, WRPS issued a Stop Work Order to the Architect Engineer (A/E), requesting that they cease further progress of the previous design. The current delay being experienced in this account is a direct result of the stop work; however, prior to the issuance of the stop work order the following drivers had contributed to the previous cumulative schedule variance, which are described below: • Delayed Process Engineering's progress of the Failure Mode and Effects Analysis (FMEA), Control and Alarm Set Point List, Design Basis Document, and two over one evaluations. Completion of the FMEA and the Control & Alarm Set Point lists have been re-sequenced in the current schedule to allow for the completion of supporting documents which include the early publish of revision 2 P&IDs and HAZOP completion. Additionally, delayed progress of the development of the two over one evaluations are a result of additional time required to resolve issues with the seismic criteria of the facility and equipment. • Update to the current execution strategy by Instrumentation and Controls Engineering re-sequences the development and completion of the input/output (I/O) Lists, Instrument Lists, Set Point Calculations, Instrument Uncertainty Analysis, and Control Logic Narratives to occur subsequent to the final publish of the revision 2 P&IDs, which is currently scheduled for early fiscal December. While the re-sequencing contributes to the overall CTD SV, the revised logic avoids the potential for future rework caused by differences between the P&IDs and design documents. • The extended effort around the Pipe Engineering's development of the Hydraulic Transient Analysis, which is due to unforeseen additional effort related to scope growth and coordination meetings. Preparation of the associated calculations was planned for completion in latter part of fiscal August, per the current schedule, these tasks will now complete in fiscal November. The additional effort has slowed the progress of the calculations and contributes to the CTD SV. • Delayed progress of the A/E review of the P&IDs and PFDs. This delay is a result of the A/E's upfront extended effort to perform a more rigorous than planned review of the P&IDs, in order to optimize the approach to the upcoming Inter-Disciplinary Review (IDR) of the process calculations and P&IDs.

  68. LAWPS CTD Variances Schedule Impact: The project team is in the planning stages of an optimized LAWPS design. It is anticipated that the current remaining baseline activities will be replaced by a revised plan. In the interim, schedule variances will continue to be realized as the Stop Work remains in effect. Corrective Action: The project team is developing a revised plan in support of an optimized LAWPS design. As the delays associated with the previous LAWPS design do not impact the execution of the optimized LAWPS, the project intends to re-baseline the LAWPS schedule, which will include setting all cumulative BCWS equal to cumulative BCWP and holistically re-planning the remaining activities. The target date for implementation of the revised plan is March 23, 2018, which will allow for the plan to be finalized in February and subsequently reviewed, approved, and implemented in fiscal March via a baseline change request (BCR). 5.5.8.2.3 P - LAWPS - Design Primary Pretreat System -$577k Cause: On October 23, 2017 the External Expert Review of the Low-Activity Waste Pretreatment System (LAWPS) Project document was released, which endorsed an optimized LAWPS facility that would vary significantly from the previous LAWPS design.

As a result, on November 20, 2017, WRPS issued a Stop Work Order to the Architect Engineer (A/E), requesting that they cease further progress of the previous design. The current delay being experienced in this account is a direct result of the stop work; however, prior to the issuance of the stop work order the following drivers had contributed to the previous cumulative schedule variance, which are described below: • In June of fiscal year 2017, an imminent change to the current design was recognized based on results of the project's integrated testing. The Integrated Project Team made the decision that the current design related to the Gas Removal System (GRS) would be replaced with Vented Ion Exchange Columns (VIXC) and additionally incorporate other essential changes required for 90% design completion. Following this decision, the project team identified urgent tasks to be performed in support of the design changes and implemented the associated scope, schedule, and budget into the PMB via BCR RPP-17-159 - LAWPS Implementation of Stage 1 GRS to Vented IX Design. Amongst these urgent tasks was the effort to revise the Balance of Plant (BOP) 3D model, which allowed the A/E to commence work while the balance of the revised execution strategy was developed. As the execution strategy matured it was evident that revisions to the BOP 3D model would require additional effort. This revised strategy has now been fully implemented via BCR RPP-17-171 - LAWPS GRS to VIXC and Essential Changes for 90% (Phase 2) and the current schedule now reflects the appropriate durations and inputs required to complete the extended effort to revise the BOP 3D Model. • Delays to Electrical Engineering drawings as a result of the incorporation of changes from the revision 2a P&IDs. The P&IDs drive the Input/output (I/O) lists, which are required to complete the wiring diagrams and schematics • The preparation of the Safety Integrity Level (SIL) Calculations, and Failure Mode and Effects Analysis (FMEA) were re-sequenced in the current schedule to incorporate impacts for revision 8 of specification 58553 and to include updates associated with the afore mention revised execution strategy Impact: The project team is in the planning stages of an optimized LAWPS design. It is anticipated that the current remaining baseline activities will be replaced by a revised plan. In the interim, schedule variances will continue to be realized as the Stop Work remains in effect. Corrective Action: The project team is developing a revised plan in support of an optimized LAWPS design. As the delays associated with the previous LAWPS design do not impact the execution of the optimized LAWPS, the project intends to re-baseline the LAWPS schedule, which will include setting all cumulative BCWS equal to cumulative BCWP and holistically re-planning the remaining activities. The target date for implementation of the revised plan is March 23, 2018, which will allow for the plan to be finalized in February and subsequently reviewed, approved, and implemented in fiscal March via a baseline change request (BCR).

  70. LAWPS CTD Variances Schedule 5.5.8.2.7 P - LAWPS - Design Facilities System -$2,063k Cause: On October 23, 2017 the External Expert Review of the Low-Activity Waste Pretreatment System (LAWPS) Project document was released, which endorsed an optimized LAWPS facility that would vary significantly from the previous LAWPS design. Following the External Expert Review, on November 16, 2017 WRPS received Letter 17-TF-0096 - CONTRACT NUMBER DE-AC27-08RV14800 - Direction to Suspend Selected Low Activity Waste Pretreatment System Design and Testing Activities, providing formal direction from the U.S. Department of Energy, Office of River Protection (DOE-ORP) to de-scope items associated with the previous LAWPS design. As a result, on November 20, 2017, WRPS issued a Stop Work Order to the Architect Engineer (A/E), requesting that they cease further progress of the previous design. The current delay being experienced in this account is a direct result of the stop work; however, prior to the issuance of the stop work order the following drivers had contributed to the previous cumulative schedule variance, which are described below: • Activities supporting the Earth Retaining System (ERS) were placed on hold as intermediate design changes are vetted to avoid unnecessary rework around the ERS. In the interim, the associated delay contributes to the CTD SV. • Structural Engineering's effort to prepare calculations for Ventilation Stack, Backup Exhauster, De-ionized Water Foundations, and Reagent Tank Access Platform has been extended. The extended duration of these tasks is attributed to waiting for building layout to be finalized, resource availability, and necessary design inputs. The extended duration has delayed the start of downstream checking and review activities as well as related drawings, which all contribute to the CTD SV. • In June of fiscal year 2017, an imminent change to the current design was recognized based on results of the project's integrated testing. The Integrated Project Team made the decision that the current design related to the Gas Removal System (GRS) would be replaced with Vented Ion Exchange Columns (VIXC) and additionally incorporate other essential changes required for 90% design completion. Following this decision, the project team identified urgent tasks to be performed in support of the design changes and implemented the associated scope, schedule, and budget into the PMB via BCR RPP-17-159 - LAWPS Implementation of Stage 1 GRS to Vented IX Design. Amongst these urgent tasks was the effort to prepare the Facilities Balance of Plant (BOP) and Primary Pretreatment System (PPS) 3D model, which allowed the A/E to commence work while the balance of the revised execution strategy was developed. As the execution strategy matured it was evident that the effort to revise the BOP and PPS 3D model would require additional time. This revised strategy has now been fully implemented via BCR RPP- 17-171 - LAWPS GRS to VIXC and Essential Changes for 90% (Phase 2) and the current schedule now reflects the appropriate durations and inputs required to complete the extended effort to revise the BOP and PPS 3D Model. • Changes to the execution strategy of the weather enclosure, design vault, and miscellaneous steel activities are a result of the incorporation of the A/E's structural subcontractor scope responsible for the Soil-Structure Interaction (SSI) initial model run and corresponding data extract. The receipt of the data was worked into the current schedule, which resulted in delays to downstream activities related to Weather Enclosure Calculations, Lag Storage Calculations/Drawings, and Design Vault Calculations. Impact: The project team is in the planning stages of an optimized LAWPS design. It is anticipated that the current remaining baseline activities will be replaced by a revised plan. In the interim, schedule variances will continue to be realized as the Stop Work remains in effect. Corrective Action: The project team is developing a revised plan in support of an optimized LAWPS design. As the delays associated with the previous LAWPS design do not impact the execution of the optimized LAWPS, the project intends to re-baseline the LAWPS schedule, which will include setting all cumulative BCWS equal to cumulative BCWP and holistically re-planning the remaining activities. The target date for implementation of the revised plan is March 23, 2018, which will allow for the plan to be finalized in February and subsequently reviewed, approved, and implemented in fiscal March via a baseline change request (BCR).

  71. LAWPS CTD Variances Schedule 5.5.8.2.8 P - LAWPS - Design Project Management & Support -$1,465k Cause: On October 23, 2017 the External Expert Review of the Low-Activity Waste Pretreatment System (LAWPS) Project document was released, which endorsed an optimized LAWPS facility that would vary significantly from the previous LAWPS design. Following the External Expert Review, on November 16, 2017 WRPS received Letter 17-TF-0096 - CONTRACT NUMBER DE-AC27-08RV14800 - Direction to Suspend Selected Low Activity Waste Pretreatment System Design and Testing Activities, providing formal direction from the U.S. Department of Energy, Office of River Protection (DOE-ORP) to de-scope items associated with the previous LAWPS design. As a result, on November 20, 2017, WRPS issued a Stop Work Order to the Architect Engineer (A/E), requesting that they cease further progress of the previous design. The current delay being experienced in this account is a direct result of the stop work. Impact: The project team is in the planning stages of an optimized LAWPS design. It is anticipated that the current remaining baseline activities will be replaced by a revised plan. In the interim, schedule variances will continue to be realized as the Stop Work remains in effect. Corrective Action: The project team is developing a revised plan in support of an optimized LAWPS design.

The target date for implementation of the revised plan is March 23, 2018, which will allow for the plan to be finalized in February and subsequently reviewed, approved, and implemented in fiscal March via a baseline change request (BCR). 5.5.8.2.9 P - LAWPS - Build to Print -$590k Cause: On October 23, 2017 the External Expert Review of the Low-Activity Waste Pretreatment System (LAWPS) Project document was released, which endorsed an optimized LAWPS facility that would vary significantly from the previous LAWPS design. Following the External Expert Review, on November 16, 2017 WRPS received Letter 17-TF-0096 - CONTRACT NUMBER DE-AC27-08RV14800 - Direction to Suspend Selected Low Activity Waste Pretreatment System Design and Testing Activities, providing formal direction from the U.S. Department of Energy, Office of River Protection (DOE-ORP) to de-scope items associated with the previous LAWPS design. As a result, on November 20, 2017, WRPS issued a Stop Work Order to the Architect Engineer (A/E), requesting that they cease further progress of the previous design. The current delay being experienced in this account is a direct result of the stop work; however, prior to the issuance of the stop work order the following driver had contributed to the previous cumulative schedule variance, which is described below: • The majority of Build to Print (BTP) work scope was put on hold while the re-plan associated with the change from the Gas Removal System (GRS) to the Vented Ion Exchange (VIXC) was planned and implemented. The current BTP plan needed to be re-worked to allow for incorporation of the associated changes and other imminent design changes. As a result, progress was limited on the activities identified as being affected by the changes. Impact: The project team is in the planning stages of an optimized LAWPS design. It is anticipated that the current remaining baseline activities will be replaced by a revised plan. In the interim, schedule variances will continue to be realized as the Stop Work remains in effect. Corrective Action: The project team is developing a revised plan in support of an optimized LAWPS design.

  72. LAWPS CTD Variances Schedule 5.5.11.2.1 P - LAWPS - Long Lead Procurements Design -$998k Cause: On October 23, 2017 the External Expert Review of the Low-Activity Waste Pretreatment System (LAWPS) Project document was released, which endorsed an optimized LAWPS facility that would vary significantly from the previous LAWPS design. Following the External Expert Review, on November 16, 2017 WRPS received Letter 17-TF-0096 - CONTRACT NUMBER DE-AC27-08RV14800 - Direction to Suspend Selected Low Activity Waste Pretreatment System Design and Testing Activities, providing formal direction from the U.S. Department of Energy, Office of River Protection (DOE-ORP) to de-scope items associated with the previous LAWPS design. As a result, the final design package for the ASME tanks has been placed on hold pending an assessment of the tank requirements of the new system, -$456k. Similar to the ASME Tanks, the Xomox valve design final package will no longer be required and has been placed on hold, -$400k. The design work for the Filter-Feed Tank submersible pumps has also been placed on hold and the procurement for the design of the pumps will not be awarded at this time, -$169k. This scope will reside in the project's PMB until a BCR is implemented to remove the associated remaining BCWS. Until then, unfavorable schedule variances will continue to be realized. Impact: The project team is in the planning stages of an optimized LAWPS design. It is anticipated that the current remaining baseline activities will be replaced by a revised plan. In the interim, schedule variances will continue to be realized as the Stop Work remains in effect. Corrective Action: The project team is developing a revised plan in support of an optimized LAWPS design. As the delays associated with the previous LAWPS design do not impact the execution of the optimized LAWPS, the project intends to re-baseline the LAWPS schedule, which will include setting all cumulative BCWS equal to cumulative BCWP and holistically re-planning the remaining activities.

January 2018 75

  73. LAWPS CTD Variances Cost 5.5.3.2.1 P - LAWPS - Design Project Management (PM) -$562k Cause: The CTD CV is primarily due to: • Labor rates. The actual average hourly rates experienced for all labor resources exceeds the hourly rate used for planning/estimating the work scope by approximately $10/hr, -$461k. • Labor usage. The actual hours experienced to date are greater than the realized calendar hours used to plan/estimate the work. These resources have not taken paid time off consistent with the planned allocation allowance used to calculate the annual realized hours (actual hours experienced are 674 hours greater than planned), -$64k. Impact: There is no impact to any other activities or accounts outside of this account. Corrective Action: No corrective action is planned at this time. 5.5.4.2.1 P - LAWPS - Design - Project Support (PS) -$2,679k Cause: The CTD CV is primarily due to: • Labor usage. Additional resources have been retained to increase the quality and completeness of the preliminary design as the project progresses towards construction. In addition, the personnel performing the work are senior level individuals and were assigned to the project based on their experience and knowledge. These resources have not taken paid time off consistent with the planned allowance used to calculate the annual realized hours. The number of actual hours experienced is greater than the hours utilized for planning the work scope by approximately 13,853 hours, -$1,515k. • Labor rates. The actual average hourly rates experienced for all labor resources exceeds the hourly rate used for planning/estimating the work scope by approximately $6/hr, -$654k. Impact: There is no impact to any other activities or accounts outside of this account. Corrective Action: No corrective action is planned at this time. January 2018 76

  74. LAWPS CTD Variances Cost 5.5.5.1.1 E - LAWPS - Permitting Dev., Prep & Reviews $357k Cause: The CTD CV is primarily due to utilizing fewer labor resources than planned. To date 12,131 hours have been earned in support of permitting activities and 7,137 actual hours have been charged, resulting in a positive CV of 4,994 hours. Preparation of draft permitting documentation has gone smoother than originally anticipated, and existing permitting staff have been able to perform the work scope in an efficient manner and avoiding the need to retain additional staffing resources originally projected to be needed, $307k. Impact: There is no impact to any other activities or accounts outside of this account. Corrective Action: The variance is favorable and does not require any corrective actions at this time. 5.5.6.2.1 P - LAWPS - Design Safety Analysis -$282k Cause: The CTD CV is primarily due to: • Flammable Gas Hazard Analysis of LAWPS Piping and Vessels. The Procurement process experienced a delay in the award of the subcontract due to clarifying scope with the subcontractor prior to award. In addition, the initial analysis was performed with assumed gas volumes and max postulated pressures which provided overly conservative results. WRPS then calculated actual pressures and gas volumes and requested a re-run of the analysis, -$153k. • Labor rates. The actual average hourly rates experienced for all labor resources exceeds the hourly rate used for planning/estimating the work scope by approximately $15/hr, -$176k. • Labor usage. The CTD CV is partially offset by labor and Staff Aug resource usage to support performance of Safety Analysis activities. Initially, Staff Aug resources were planned to perform a significant portion of the safety activities. However, it was subsequently determined that the direct safety labor resources, with historical knowledge and experience of the project, would perform these activities, $73k. Impact: There is no impact to any other activities or accounts outside of this account. Corrective Action: No corrective action is planned at this time. January 2018 77

  75. LAWPS CTD Variances Cost 5.5.7.1.1 P - LAWPS - Tech Maturation Program & Misc Tests $350k Cause: The CTD CV is primarily due to: • To date, the engineering support required to oversee performance of subcontracted national laboratory support has been less than planned. The national laboratories (SRNL and PNNL) have extensive historical knowledge and experience with the subcontracted work scope and the WRPS Technology Maturation personnel, which allows them to perform the work scope efficiently with reduced oversight, $142k. • In comparison to the original plan for the sRF-3 testing and the final subcontract award, the engineering design was further developed and refined. This resulted in some experienced efficiencies during the testing phase, $183k. There is no change to the variance drivers from the prior reporting period. Impact: There is no impact to any other activities or accounts outside of this account. Corrective Action: The variance is favorable and does not require any corrective actions at this time. 5.5.7.1.2 P - LAWPS - Tech Mature. Integrated Scale Test $477k Cause: The CTD CV is primarily due to: • The account is experiencing labor price/usage efficiencies. Originally, staffing levels were assumed and planned at a higher level to provide oversight and support to the Integrated Engineering-Scale test. Project Manager and Project Controls support were planned under this account. However, this support has been provided by resources already assigned to the project under the Project Management account. Also, the actual hourly rate experienced in this account for engineering support/oversight is less than the planning rate by approximately $16/Hr, $775k. • The actual cost for resin procurements was significantly less than planned. Originally, resin was planned to be procured in two batches. The quantity of required resin required was reduced to 500 gallons based on the refined needs of the project, $490k. • National Laboratory Technology Maturation program testing and oversight has experienced a negative cost variance that was driven by revisions to the test plan. The biggest impact was caused by a change in the design to eliminate the Hydrogen Diffusion Design Feature (HDDF) and provide a standby, on demand, vessel ventilation for flammable gas mitigation, -$923k. Impact: There is no impact to any other activities or accounts outside of this account. Corrective Action: The variance is favorable and does not require any corrective actions at this time. January 2018 78

  76. LAWPS CTD Variances Cost 5.5.8.2.3 P - LAWPS - Design Primary Pretreat System -$1,552k Cause: The CTD CV is primarily due to: • To date the modeling effort required more resources than planned. This is attributed to the extensive comment incorporation from the 30% design reviews as well as the preparation of story boards and a model fly through, which was unplanned. The model was matured to higher level of detail than planned and prepared to be free from clashes, in support of the accelerated 60% design requirements. Additionally, options for above grade maintenance access for the lag storage tanks and pipe routing changes around the Lag Storage area were required to satisfy facility construction requirements. • Studies/Calculations variance is due to pipe stress and process engineering requiring more effort because of the inefficiencies associated with concurrent development of P&IDs, mechanical design, and piping design. Further variance in pipe stress was caused by the effort required to develop pipe stress design basis criteria for safety related systems (including seismic requirements and PUREX nozzle qualifications including TFC-ENG-DESIGN-C-60 requirements). Additional hours were spent developing a rationale presentation to WRPS for design justification for backpressure requirements for the filtration calculations, which was not included in the original estimate. The lag storage calcs required additional effort beyond what was estimated due to specification changes that were made after completion of advanced conceptual design. Process equipment calculations for mechanical design and piping were inefficient due to multiple iterations required to complete the 30% Delta Design Review package. • The Ion Exchange (IX) and Cross-Flow Filter (CFF) packages required additional hours to advance beyond what was planned. Drawing activities were performed to support the 30% delta review packages and the completion of the long lead procurement packages that are required to meet the September 2016 PBI milestone. Additional unplanned hours to perform these activities were incurred to ensure the milestone date would be met. In addition, a greater than planned effort was required to provide the drawings necessary to present the high level of detail that is going to be included in the 60% package (300+ mechanical drawings). Additional resources were required to ensure the 60% part A completion date was achieved and IDR comments had to be addressed as they were received rather than on complete closure of the IDR cycle. Impact: On November 16, 2017 WRPS received Letter 17-TF-0096 - CONTRACT NUMBER DE-AC27-08RV14800 - Direction to Suspend Selected Low Activity Waste Pretreatment System Design and Testing Activities, providing formal direction from the U.S. Department of Energy, Office of River Protection (DOE-ORP) to de-scope items associated with the current LAWPS design. As a result, on November 20, 2017, WRPS issued a Stop Work Order to the Architect Engineer (A/E), requesting that they cease further progress of the current design. This account will not be impacted by further charges. Corrective Action: The variance is not recoverable and is reflected in the EAC. January 2018 79

  77. LAWPS CTD Variances Cost 5.5.8.2.6 P - LAWPS - Design Balance of Plant System -$1,639k Cause: The CTD CV is primarily due to: • Electrical specification, drawing, and modeling efforts have been accelerated to support the project schedule. The effort for specification development has been impacted by the iterative process required on the procurement and quality sections of the specifications. Additional unplanned effort to complete electrical drawings has been realized as a result of new design requirements and the need for more design drawings. Additionally, the Electrical Engineering effort for the Hazardous Area Classification required more effort than planned to address review comments and different base assumptions. • On October 23, 2017 the External Expert Review of the Low-Activity Waste Pretreatment System (LAWPS) Project document was released, which endorsed an optimized LAWPS facility that would vary significantly from the current LAWPS design. As a result, progress on the current design was slowed and on November 20, 2017 a Stop Work Order was issued to the Architect Engineer directing them to cease work on all current design in accordance with Letter 17-TF-0096 – CONTRACT NUMBER DE-AC27-08RV14800 – Direction to Suspend Selected Low Activity Waste Pretreatment System Design and Testing Activities, received from U.S. Department of Energy, Office of River Protection (DOE-ORP) on November 16, 2017. The majority of the inefficiencies in the current period were due to the slowdown of design activity, and the A/E not being able to ramp down staff as quickly as the work slowed. This was due to both WRPS and the A/E knowing the stop work was forthcoming, but officially not received until later in the month. WRPS worked with ORP and the A/E to stop the work as quickly as possible, it was a detailed process and significant considerations needed to be worked through. This took some time to ensure it was communicated appropriately, thus the costs continued until the official notice was delivered. • The BOP Controls Specs, Control System Spec, Safety System Spec, and developing the CSI spec format and requirements have been impacted by the redefinition of the quality requirements. This change in formatting has caused unplanned specification rework to meet the new format requirements. • Development of the SIL/FMEA calculations contributes to the unfavorable cost variance. Several activities have required effort beyond what was initially planned because more complex analysis has been required. In addition, higher costs have been realized due to additional resource ramping up and increased effort to perform the work. The original estimate was for 6 Safety Integration Functions (SIFs), and through the development of the design, there are now 19 SIFs that are factored into the calculations requiring more time and effort to complete. • Control drawings have been revised multiple times and continue to be updated. Control cabinet and room layouts have been revised to address additional space requirements for elevated I/O counts. Impact: No further impact is expected since the stop work order has been issued. Corrective Action: A Stop Work Order was issued to the A/E on November 20, 2017, stopping all further charges to this control account. The project team is now developing a revised plan in support of the optimized LAWPS design. Phases of the revised plan have been approved and implemented to allow for urgent work to progress under a new WBS structure (5.05.25). Subsequent BCRs will be used to implement the remaining scope, schedule, and budget and replace the existing remaining baseline activities. The majority of the revised plan is targeted for implementation by the end of fiscal March 2018. January 2018 80

  78. LAWPS CTD Variances Cost 5.5.8.2.7 P - LAWPS - Design Facilities System -$3,252k Cause: The CTD CV is primarily due to: • Weather Enclosure Structural calculations and seismic analysis (SSI) activities performed by subcontractor SGH, Vault Concrete calculations, Vault Steel calculations, and Cell Cover calculations started late due to contract negotiations that resulted in cost and schedule impacts caused by the tightly compressed schedule. The subcontract award to SGH was significantly higher than the A/E baseline estimate for the work scope. Additionally, vault steel, vault cover, and vault concrete calculations all went through multiple iterations as equipment arrangements matured and ensure alignment with the concrete substructure. • Additional effort for Architectural drawings has been required due the significant coordination required with the other engineering disciplines and with SGH, as their designs have matured and changes are needed to the architectural model and drawings. • Architectural specifications for the Weather Enclosure involved a larger number of specs than originally anticipated and the Change Facility experienced significant changes due to requests made during the WRPS design reviews to accommodate operational and radiation protection needs. • 3D modeling activities went through a number of iterations in order to synchronize the SGH model with the A/E structural vault model and the integrated A/E Smart Plant model. • Additional effort for Structural drawings has been required due to the need to align the initial vault designs with the SGH design of the upper weather enclosure structures and to perform the weather enclosure structure drawings. Impact: No further impact is expected since the stop work order has been issued. Corrective Action: A Stop Work Order was issued to the A/E on November 20, 2017, stopping all further charges to this control account. The project team is now developing a revised plan in support of the optimized LAWPS design. Phases of the revised plan have been approved and implemented to allow for urgent work to progress under a new WBS structure (5.05.25). Subsequent BCRs will be used to implement the remaining scope, schedule, and budget and replace the existing remaining baseline activities. The majority of the revised plan is targeted for implementation by the end of fiscal March 2018. January 2018 81

  79. LAWPS CTD Variances Cost 5.5.8.2.8 P - LAWPS - Design Project Management & Support -$362k Cause: The CTD CV is primarily due to the effort for the Architect Engineer (A/E) to deliver all completed and partially completed work products following the stop work order issued to the A/E on November 20, 2017. The stop work order followed Letter 17-TF-0096 – CONTRACT NUMBER DE-AC27-08RV14800 – Direction to Suspend Selected Low Activity Waste Pretreatment System Design and Testing Activities, received from the U.S. Department of Energy, Office of River Protection (DOE-ORP) on November 16, 2017. The effort to deliver all completed and partially completed work products, is unbudgeted and therefore all associated cost contributes to the current month’s unfavorable variance, -$820k. This variance is somewhat offset by a favorable variance achieved in the A/E's Project Management and Support of the previous LAWPS design where their management and project support functions were able to effectively engage their teams utilizing less resources than planned, $332k. The unfavorable variance is additionally offset by the more recent effort to support planning and setup associated with an optimized LAWPS design, $126k. This can be attributed to the A/E’s ability to support this effort with limited resources. Impact: The control account is forecasted to be overspent; however, costs associated with the effort to deliver all completed or partially completed work products is to be included in Contract Change Proposal 18-007 and the budgeted value of the control account will ultimately be increased by the value negotiated for this effort. Corrective Action: As part of the Letter 17-TF-0096, WRPS was requested to provide a contract change proposal. The effort to develop contract change proposal 18- 007 is underway and is currently due by March 02, 2018. The effort associated with the delivery of all completed or partially completed work products is to be captured in this proposal and later negotiated. January 2018 82

  80. LAWPS Challenges/Issues/Opportunities Challenges • Integration of LAWPS with TSCR and AP Farm Upgrades work scope.

  85. Chief Technology Office & Closure Major Current Month Variances Cost 5.02.04.02.06 Integrated Disposal Facility Perf Assessment $168k • Cause : The CM CV is primarily due to planned subcontract support during the Low-Level Waste Disposal Facility Federal Review Group (LFRG) review. Four subcontractors were originally planned to provide Subject Matter Expert support during the LFRG review (Intera, PNNL, SRNL, and SRR). However, over the course of the review, the majority of the questions pertained to work performed by Intera. Little to no support was required during the review by PNNL, SRNL, and SRR resulting in cost efficiencies for the planned support. The LFRG review completed in the current reporting period. • Impact: There is no impact to any other baseline activities outside of this account. 5.03.12.02.02 Technology Maturation & Analysis $131k • Cause : The CM CV is primarily due to resource usage efficiencies in the Technology Maturation and Analysis level of effort (LOE) account. Less management oversight/support has been required than was originally planned. The efficiencies are a result of the following: 1) the senior project management position has been filled by a staff member already on-board, while the other project manager position has been supported in the interim by another staff member also already on-board. 2) The SRNL technical support resource is currently supporting the work scope under an Approved Funding Program (AFP). Under an AFP, the funding is transferred to SRNL via DOE. AFP costs are not processed through the TOC financial systems. However, the performance for the associated work scope is reported, resulting in a favorable cost variance. • Impact: There is no impact as a result of the CM CV. 5.03.06.01.04 IDF Glass Testing $130k • Cause : The CM CV is primarily due to Stage III test instructions and Lysimeter modeling. The Stage III test instructions were completed by the National Laboratory (PNNL) subcontractor with fewer resources than originally planned. PNNL performed the Stage I and II testing and extensive technical and historical knowledge for this particular scope. The pre-experimental Lysimeter modeling was not as complex as anticipated, and was completed early, resulting in fewer resources required to complete the modeling scope. • Impact: The control account is forecasted to be underspent upon completion of the work scope. January 2018 88

  86. Chief Technology Office & Closure Major Current Month Variances Schedule 5.03.01.07.03 Waste Feed Delivery Technology -$363k • Cause : The CM SV is primarily due to the 1) Mechanical Waste Gathering system (MWGS): Atkins is performing in-house proof of principle testing on the MWGS. The duration of this testing is longer than originally anticipated. The extended testing duration has resulted in a delay in the start of design activities. 2) Additionally, the NDE Functions and Requirements document was more complicated and took longer than planned. This resulted in delays to the start of the Sensor fabrication and instrument testing, and the awards of second-tier subcontracts to WSU, Guided Wave, and Innerspec for sensor maturation testing. 3) The start of the On- line Monitoring activities were delayed to perform an evaluation of ORP/WTP’s On -Line program to ensure there was not a duplication in testing. • Impact: No impact to any other activities outside this account. 5.03.12.02.04 Solid Secondary Waste Stream Tech Mat (DFLAW) -$133k • Cause : The CM SV is due to DFLAW Solid Secondary Waste Phase 3 testing. Savannah River National Laboratory (SRNL) was performing the DFLAW Solid Secondary Waste testing. An agreement on the contracting method/procurement process for Savannah River National Laboratory (SRNL) could not be reached. This resulted in the delay of starting the Phase 3 testing. The work scope will be awarded to another National Laboratory. • Impact: No impact to critical path or other control accounts. January 2018 89

  87. Chief Technology Office & Closure Major Contract to Date Variances Cost 5.03.12.02.01 Technology Development $3,177k  Cause : The CTD CV is due to the following: 1) Labor usage efficiencies in FY 14. At the beginning of FY 14, a significant portion of scope was not authorized. As a result, labor resources were redirected to other project accounts. In Jun 14, the afore-mentioned scope was authorized and implemented into the baseline. However, the reinstatement of staff to the project was slower than expected due to completion of reassigned work. 2) SRNL actual costs under Inter Entity Work Order (IEWO) contracts were not processed through TOC financial systems, which resulted in a favorable cost variance. 3) Labor usage efficiencies experienced in FY 15 in the LOE account for Technology Development and Program Management. 4) PNNL subcontract labor usage and price efficiencies under the Low Temperature Waste Form account were realized in FY 15. This is a result of their historic knowledge and expertise of the work scope.  Impact: No impact to the project. The SRNL IEWO contracts (IEWO = BCWS, BCWP without ACWP) will cause a final positive CTD variance.  Corrective Action : There is no corrective action planned. The favorable CTD CV is due to efficiencies realized in previous fiscal years. 5.02.04.02.03 RCRA Closure Plan Updates $2,186k  Cause : The CTD CV is due to labor & subcontractor resource efficiencies. Internal subject matter experts were used, instead of additional subcontractor support, to develop the TPA Closure Plans (Tier 1, 2, & 3), WIR, and DOE 435.1 Closure Plan. Realignment of internal resources supporting multiple activities within the organization resulted in labor utilization efficiencies. Also, comments received from ORP required fewer document revisions than planned.  Impact: Using internal subject matter expert support has resulted in an overall cost savings for the TPA Tier 1, 2, and 3 Closure Plans, WIR development, and DOE 435.1 Closure Plan development. Cost efficiencies have been accounted for in the EAC.  Corrective Action : No corrective action. Variance is favorable. 5.03.06.01.04 IDF Glass Testing $2,075k  Cause : The CTD CV is primarily due to the following: 1) Subcontract resources provided by Pacific Northwest National Lab (PNNL) experienced usage efficiencies due to their historical knowledge and expertise of the IDF Glass Testing Program, FYs 14 - 16, and FY 17. 2) WRPS labor resource usage in FY 14 was less than the planned baseline for oversight/management of the IDF Glass Testing Program. This efficiency is attributed to the labor resources and confidence in subcontractor's historical knowledge and expertise of the work scope, which required less oversight/management.  Impact: There is no impact to any other activities outside of this account.  Corrective Action : There is no corrective action planned. CTD CV is favorable and a result of previous fiscal year efficiencies. 5.03.12.02.02 Technology Maturation & Analysis $2,074k  Cause : The CTD CV is primarily due the following: 1) Labor usage efficiencies have been realized in the Technology Maturation & Analysis LOE account, as there has been less management oversight/support required than what was originally planned. This is primarily due to a senior project manager being moved to another project in mid-Fiscal Year (FY) 16, the attrition of project manager in mid-FY 17, and the attrition of a senior engineer mid-year FY 16. The responsibilities for the senior project manager and the senior engineer have been filled by existing resources. The other project manager position has been supported in the interim by another staff member also already on-board. 2) Resource usage efficiencies related to the subcontract support for external reviews and technical support in the Technology Maturation & Analysis LOE account. To date, there has been less subcontract support required than originally planned.  Impact: There is no impact to any other activities outside of this account.  Corrective Action : There is no corrective action planned. 5.03.01.07.03 Waste Feed Delivery Technology $1,882k  Cause : The CTD CV is primarily due to the following: 1) FY 17 cost efficiencies realized in the preparation for Hanford Waste End Effector (HWEE) Testing, and Under Double-Shell Tank (DST) Non-Visual Inspection Effectiveness Testing. The definition phase of both projects was performed with significantly less resources than originally planned as the project team has been able to leverage existing data to its advantage for the Simulant and End Effector design. Additionally, PNNL and WRPS were able to effectively engage their team and contributing counterparts in preparing for both tests. 2) Subcontract technical support of emerging engineering studies, under WFD Technology Solutions. This is a level of effort activity and required less support than planned in FY 14 and FY 15. 3) The subcontract work performed by EnergySolutions for the Small-Scale Solids Delivery Testing, which started in FY 2014 and completed in the 4th quarter of FY 15, experienced cost efficiencies due to its labor pricing and usage being less than January 2018 90

  88. Chief Technology Office & Closure Major Contract to Date Variances Cost (cont.) 5.03.01.07.05 WFD System Performance $1,396k  Cause : The CTD CV is primarily due to labor usage and price efficiencies in subcontract resources and labor. 1) The subcontract work for the Isolok Reference Sampler Testing, which began in FY 14 and completed in the third quarter of FY 15, experienced efficiencies due to subcontractor labor rates and actual usage being less than originally assumed in the baseline. Also, less subcontract oversight was required due to the experience of the subcontracted resources. 2) Fewer labor resources were used than what was planned in support of the Feed Delivery Technical Issue Resolution in FY 2014.  Impact: There is no impact to any other activities outside of this account.  Corrective Action : There is no corrective action planned. The favorable CTD CV is due to efficiencies realized in previous fiscal years. 5.03.10.03.02 Secondary Waste Form Development $1,290k  Cause : The CTD CV is primarily due to resource usage and price efficiencies realized by the National Laboratories subcontracted to perform this scope. 1) The work being performed by SRNL in support of the Waste Form Development of Fresh Properties has experienced resource usage efficiencies in the work performed to date and the project expects that this trend will continue with their remaining work. The contract was awarded to SRNL for significantly less than what was originally estimated and to date, they have been able to execute the scope within the funds awarded and they do not expect to exceed this. 2) PNNL experienced resource usage and price efficiencies in FY 14. This is attributed to the fact that PNNL has worked extensively in the past on similar work scope and was able to engage efficiently to support this effort. 3) The National Labs (PNNL & SRNL) contracted to support Secondary Waste Form Development in FY 15 also experienced resource usage and price efficiencies, again due to the fact that the national labs have worked extensively in the past on similar work scope and were able to engage efficiently to support this effort.  Impact: There is no impact to any other activities outside of this account.  Corrective Action : There is no corrective action planned. The favorable CTD CV is due to efficiencies realized in previous fiscal years. 5.02.04.01.01 Closure Program Management $1,027k  Cause : The CTD CV is primarily due to labor efficiencies. In prior fiscal years, this level of effort account experienced vacancies in technical personnel, both direct and staff aug positions. The scope outside of this account was designated as high priority. Resources planned under this account were diverted to support the higher priority work scope.  Impact: There are no impacts to baseline activities outside of this control account.  Corrective Action : No corrective actions. This is a favorable variance. 5.02.04.02.07 Waste Magt Area C Performance Assessments -$629k  Cause : The CTD CV is primarily due to the FY16 additional direct and subcontract labor support required to complete an additional Exposure Scenario Document and three additional environmental model calculation files (EMCF) in preparation for the WMA C PA review by the Low Level Waste Federal Review Group (LFRG). Additionally, direct labor and subcontractor technical support was necessary to address review comments in updates to the WMA C PA documentation in FY16. The modeling estimates were based on the Savannah River Site modeling effort. The Hanford site modeling effort is proving to be much more difficult technically, requiring increased modeling and documentation to complete the scope.  Impact: The additional modeling documentation and review and comment resolution support for completion of WMA C PA related activities in FY16 continue to have impacts on CTD in FY17. The EAC has been updated and additional variances are being tracked for activities that were currently in progress.  Corrective Action : There are no corrective actions planned. The variance is not recoverable and is reflected in the EAC. January 2018 91

  89. Chief Technology Office & Closure Major Contract to Date Variances Schedule 5.02.01.04.01 Vadose Zone Mgmt & Regulatory Docs -$1,207k  Cause : The CTD SV is primarily due to delays in receiving Ecology's comments on the RFI and CMS documents. The RFI and CMS documents were submitted to Ecology in DEC 16, and comments were expected the week of FEB 15, 17. However, Ecology has not returned comments on these two documents. Ecology submitted a letter (17-NWP-058) to ORP on MAY 22, 17 requesting an extension for completing its review and final comments on WMA C documents (RCRA Closure Analysis of WMA C, PA of WMA C, Analysis of Past Tank Waste Leaks and Losses, and BRA for WMA C) by JUL 16, 17. Ecology has requested several extensions (via letter transmittals) to complete its review. The latest letter received in DEC 17 anticipated a completed review by JAN 16, 18. However, comments were not received in January. Until Ecology completes its review and comments of these documents, it can't start its review and comments of the RFI/CMS. Ecology will address the RFI/CMS documents after completion of WMA C document reviews.  Impact: The SV is expected to continue until comments are received from Ecology on the RFI and CMS documents. Despite the delays, WRPS will still be able to respond to the comments and update the reports in order to meet the TPA milestone (M-045-62: Submit Phase 2 Corrective Measures Implementation Work Plan for WMA C) by its due date. However, work on the CMIP cannot proceed as planned and was re-planned. A modification to the baseline activities was implemented under BCR RPP-17-134, which better aligned the CMIP activities with the official proposed Milestone finish date of AUG 31, 28 (17-TF-0046).  Corrective Action : No corrective actions planned. 5.02.04.02.07 Waste Mgt Area C Performance Assessments -$886k  Cause : The CTD SV is primarily due to (1) a delay in receiving comments from Ecology on WMA C documents - Past Leaks Analysis, Baseline Risk Assessment, RCRA Closure Analysis, and (2) a delay in initiating NRC review of the WMA C PA as planned/scheduled. This NRC review of the WMA C PA is linked to the NRC review of the WMA C WIR being done under WBS 5.2.4.2.3.2 (DOE 435.1 Closure Plans). The WIR was transmitted to DOE-HQ for review by the Office of General Council in JUL 17. The time required for review and approval by the Office of General Council at DOE- HQ to submit the WIR to NRC for review is expected to delay the start of the concurrent NRC review of the WMA C PA and WIR until the FEB to MAR 18 timeframe.  Impact: The delay in receiving comments back from Ecology on the following WMA C documents, Past Leaks Analysis, Baseline Risk Assessment, RCRA Closure Analysis, will delay completion of updates to these documents until sometime in FY18. The delay in the start of NRC review will push out completion of the concurrent PA review by the NRC into FY18 and will impact completion of updates to the WMA C PA in response to NRC review comments until, at the earliest time, the end of the last quarter of FY18. The delay in the start of the NRC review of the WMA C PA will have a similar impact in the NRC review for the WMA C WIR and updates planned in response to NRC review comments on the WIR (See 5.2.4.2.3.2 DOE 435.1 Closure Plans).  Corrective Action : No corrective action. 5.03.12.02.04 Solid Secondary Waste Stream Tech Mat (DFLAW) -$660k  Cause : The CTD SV is due to DFLAW Solid Secondary Waste Phase 3 testing. Savannah River National Laboratory (SRNL) was performing the DFLAW Solid Secondary Waste testing. An agreement on the contracting method/procurement process for Savannah River National Laboratory (SRNL) could not be reached. Phase 3 testing activities were originally planned to start late FY 17 4th quarter. This resulted in the delay of starting the Phase 3 testing. The work scope will be awarded to another National Laboratory.  Impact: No impact to critical path or other control accounts.  Corrective Action : There is no corrective action for the CTD SV. The SV is expected to continue into the third quarter of fiscal year 2018. January 2018 92

  90. Chief Technology Office & Closure Major Contract to Date Variances Schedule (cont.) 5.02.04.02.03 RCRA Closure Plan Updates -$651k  Cause : The CTD SV is primarily due to delayed receipt of comments from ORP and Ecology on the TPA Closure Plans, and from ORP and DOE-EM on the WIR evaluation.  Impact: The delay will impact the completion of final drafts of the TPA Closure Plans and DOE 435.1 documents (WIR Evaluation and Closure Plans), which have been carried over from FY17 into FY18.  Corrective Action : A strategy is being developed to accelerate the final approval of the DOE O 435.1 documents (WIR Evaluation and Closure Plans). Discussions are on-going with Ecology on the path forward for the TPA Closure Plans. The CAM and project leads are aware of the delays and discussing this topic weekly. 5.03.01.07.03 Waste Feed Delivery Technology -$524k  Cause : The CTD SV is primarily due to the 1)Mechanical Waste Gathering system (MWGS) starting later than originally planned due to Atkins Proof of Principle testing in-house on their own Mechanical Waste Gathering unit to be ready for our MWGS design, which delayed our start. This contract with Atkins is currently being reviewed and should be placed by the end of February. 2) Additionally, the NDE Functions and Requirements document was more entailed and took longer than planned. Sensor fabrication and instrument testing was started late due to the final Requirements document and PNNL’s procurement process to award WSU, Guided Wave and Innerspec contracts for sensor maturation testing. 3) WRPS On-line Monitoring Development program chose to evaluate ORP/WTP’s On -line program as to not duplicate testing. At the end of January, it was deemed there was no duplication and our procurements have begun.  Impact: There is no impact to any other activities, or to the critical path.  Corrective Action : There is no corrective action for the CTD SV. The SV is expected to continue into the third quarter of fiscal year 2018. 5.03.12.02.03 Liquid Secondary Waste Stream Tech Mat (DFLAW) -$412k  Cause : The CTD SV is primarily due to the EMF Bottoms leachate testing that was originally planned to perform to EPA standard 1313 (28 day duration). It was subsequently determined that additional testing needed to be performed to EPA standard 1315 (63 day duration) to obtain adequate, meaningful data. The testing to EPA standard 1315 will require additional analysis. Additionally, agreement as to the contracting method/procurement process for Los Alamos National Lab (LANL) (EMF glass and simulant testing work scope) and Savannah River National Lab (SRNL) (EMF Concentrate IX testing) has not been reached resulting in delays to the award of these subcontracts to another vendor.  Impact: No impact to critical path or other control accounts.  Corrective Action : There is no corrective action for the CTD SV. The SV is expected to continue until the contract is let, the second quarter of fiscal year 2018. Currently evaluating National Labs to do the work, then contracting the lab to perform the scope as efficiently as possible. 5.03.06.01.04 IDF Glass Testing -$386k  Cause : The CTD SV is primarily due to the Lysimeter facility upgrades. Transfer of the Field Lysimeter Test Facility (FLTF) and needed upgrades has delayed procuring equipment, preparing test materials and preparing the Lysimeter samples for insertion into the facility. It is anticipated that these activities will not start until the second quarter of FY 18. Upon completion of the upgrades to the facility, PNNL can perform the detailed test configuration definition and pretest modeling for the Lysimeter testing.  Impact: The transfer of the Field Lysimeter Test Facility (FLTF)from CH2MHILL to WRPS, and upgrading the facility is largely driving out the preparation of the Lysimeter for Waste Form Insertion and is expected to move out to the second quarter of FY 18. This will delay the start of testing to be done in FY 18; however, there is no current impact to critical downstream tasks as a result of this schedule variance.  Corrective Action : There is no corrective action for the CTD SV. The SV is expected to continue to the end of fiscal year 2018. January 2018 93
