Safely Delivering DOE’s Vision for the East Tennessee Technology Park Mission The Disposition of Former “No Path To Disposal” Wastes – A ETTP 2016 Update John Wrapp Waste Disposition Manager March 10, 2016 Safely Delivering DOE’s Vision for the 1 East Tennessee Technology Park Mission
Agenda • Initial “No Path To Disposal” (NPTD) Waste Inventory • Regulatory Framework • Contractual Requirements • Disposition Approach • Current Status • Remaining Challenges Safely Delivering DOE’s Vision for the 2 East Tennessee Technology Park Mission
NPTD Waste Inventory Quantity Reason for “No Waste Category Volume # Path” Designation (m 3 ) Containers Classified F027 Mixed LLW Debris 5.8 11 F027 Listing, Classified Classified PCB LLW Debris 9.4 4 PCBs, Classified Reactive Mixed LLW Returns 0.8 4 Reactivity Characteristic Classified Mixed LLW Liquids/Debris/Soils 18.3 27 Classified MLLW Mercury Mixed LLW Debris Returns 15.2 34 Mercury, Organics Dioxin/Furan Mixed LLW Liquids and Debris 15.8 61 Underlying Hazardous Constituents (UHCs) Safely Delivering DOE’s Vision for the 3 East Tennessee Technology Park Mission
Disposition Approach • Revisit historical waste characterization Information; thoroughly understand the waste – Process knowledge – circumstances and processes of generation and subsequent storage and handling – Available characterization data – Current condition of waste and waste container – Eliminate overly conservative characterization • Review the regulatory framework – what’s allowed and what’s not allowed • Revisit current available treatment technologies and disposal options • Fill data gaps • Reclassify and re-characterize Safely Delivering DOE’s Vision for the 4 East Tennessee Technology Park Mission
Current Status Reason for “No Disposition Waste Category Path” Path Identified Complete? Designation Classified F027 Mixed LLW Debris F027 Listing, NNSS Classified Classified PCB LLW Debris PCBs, Classified NNSS Reactive Mixed LLW Returns Reactivity M&EC, NNSS Characteristic Classified Mixed LLW Liquids/Debris/Soils Classified MLLW M&EC, NNSS Mercury Mixed LLW Debris Returns Mercury, Organics NNSS Dioxin/Furan Mixed LLW Liquids and Debris UHCs 29 to M&EC, 31 In process awaiting results of treatability study Sodium and Lithium Hydride shields Reactivity 22 to M&EC, 38 In process (material for recovery) Characteristic TBD Safely Delivering DOE’s Vision for the 5 East Tennessee Technology Park Mission
Remaining Challenges • Dioxin & Furan Waste – Problem: LLW includes both solid phase and liquid phase dioxin/furan F and U hazardous waste codes Treatment technology exists to treat the primary waste, however the secondary liquids have no treatment/disposal path – Solution: Able to re-characterize and remove Dioxin & Furan codes which opened path for 29 of 60 to DSSI for incineration. Treatability study under way for remaining 31 containers Safely Delivering DOE’s Vision for the 6 East Tennessee Technology Park Mission
Remaining Challenges (cont.) • Sodium and Lithium Shields – Problem: Large, odd-shaped items containing bulk sodium metal or lithium hydride – Solution: Prepared Request for Expression of Interest – Result: Path for in-cell macro at Clive has hit regulatory hurdle M&EC can treat 22 of the small shields that fit into their treatment unit. Searching paths for remaining shields Safely Delivering DOE’s Vision for the 7 East Tennessee Technology Park Mission
Complex Wide Challenges • Eventual loss of M&EC South Bay will impact complex with processing high activity waste • Due to lack of waste destined for several specific treatment technologies, TSDRF’s are considering eliminating for business reasons – Could result in no treatment technology available and “no path to disposal” waste Safely Delivering DOE’s Vision for the 8 East Tennessee Technology Park Mission
ETTP STATUS • 2016 Vision – Complete demo of K-27, in progess • 2020 Vision – Complete UCOR Contract Scope • Determine gap between contract scope and end-state vision Safely Delivering DOE’s Vision for the 9 East Tennessee Technology Park Mission
