Program Overview Topics

  • Industry Trends Program Results
  • ROP Enhancement Activities
  • ROP Self-Assessment Revisions

11

slide-12
SLIDE 12

No Adverse Industry Trends

  • ITP complements licensee-specific

ROP – Assesses industry-wide performance

  • FY 2014 results

– No short-term indicator prediction limits exceeded – No long-term statistically significant adverse trends

12

slide-14
SLIDE 14

Considering Changes to Industry Trends Program

  • ITP results provide confidence in
  • verall industry safety performance
  • Planning to implement several

program enhancements to: – Assess all ROP cornerstones – Reduce time delays – Realize substantial resource savings

14

slide-15
SLIDE 15

Reactor Oversight Process Enhancements Underway

  • ROP remains effective overall
  • Numerous updates completed or in

progress – 130+ inputs from multiple sources – Grouped and prioritized for action – Working most substantive issues first

15

slide-16
SLIDE 16

Baseline Inspection Procedures Being Updated

  • Baseline Inspection Procedure

Improvement Project

  • Key activities:

– Performance “Issue Screening” – Problem Identification and Resolution Inspection – Component Design Basis Inspection – Independent Spent Fuel Storage Installations

16

slide-17
SLIDE 17

Progress Made on Assessment Program Changes

  • Completed major revision to

“substantive cross-cutting issue” process

  • Proposing revision to definition of

“degraded cornerstone”

17

slide-18
SLIDE 18

Streamlining the Significance Determination Process

  • Phase 1 – Completed “Business Process

Improvement” effort on existing process to: – Improve coordination between regional and headquarters staff – Reinforce management expectations for timeliness of risk analyses – Focus on impacts of modeling uncertainties and assumptions

18

slide-19
SLIDE 19

Streamlining the Significance Determination Process (cont.)

  • Phase 2 – Longer-term effort to:

– Ensure optimal use of integrated risk-informed decision-making – Simplify analyses to improve timeliness and minimize resources – Seek input from key internal and external stakeholders

19

slide-20
SLIDE 20

Enhancing ROP Communications using Plain Language

  • Employing several new and

revised tools

  • ROP external webpage redesign
  • ROP internal webpage redesign
  • Obtaining stakeholder feedback

20

slide-21
SLIDE 21

No 2014 ROP Self-Assessment Performed

  • Commission approved request to

forgo 2014 self-assessment to: –Develop new self-assessment process –Implement ROP enhancements

  • Plan to implement new process in

CY 2015

21

slide-22
SLIDE 22

Revised Self-Assessment Approach Adds Accountability

  • Three major elements

– Use metrics to assess “compliance” with ROP governance – Evaluate effectiveness of recent program changes – Perform targeted, in-depth assessment(s)

22

slide-23
SLIDE 23

Request to Eliminate Reporting Requirements

  • Three extensive annual evaluations

conducted as part of existing self- assessment process

– Regulatory impact summary – ROP resource expenditures – Resident Inspector demographic

  • Minimal decision-making insights
  • All require Commission approval to

discontinue

slide-25
SLIDE 25

Increased Regulatory Oversight

  • Transition to IMC 0350 process

(December 2011)

  • Comprehensive corrective actions

independently verified via extensive NRC inspection

  • CAL closed and post-restart CAL

issued (December 2013)

  • Plant startup (December 2013)

25

slide-26
SLIDE 26

Increased Regulatory Oversight (cont.)

  • IMC 0350 process termination

criteria

– Effective long-range improvement program – Sufficiently implementing the CAP – Demonstrated safe plant performance – Adequately addressed issues leading to invoking IMC 0350

26

slide-27
SLIDE 27

Increased Regulatory Oversight (cont.)

  • 13-person NRC team inspection in

July 2014

  • Concerns identified with

implementation of CAP

  • NRC follow up team inspection

conducted in January 2015

– Significant CAP improvements

27

slide-28
SLIDE 28

Return to Normal NRC Oversight

  • NRC concluded IMC 0350 process

termination criteria satisfied

– Transition of station to Column I of the Reactor Oversight Process – All performance indicators in effect

  • Post-restart CAL follow up

inspections

– Containment internal structure – Design-Basis Reconstitution initiative

28

slide-29
SLIDE 29

Return to Normal NRC Oversight (cont.)

  • NRC staff effort since entry into

IMC 0350

– Approximately 61,000 hours total – 45,000 inspection hours – 16,000 hours associated with licensing and assessment activities

Safety Significant Performance Issues

  • Yello

ellow w finding finding – Sta Stator tor dr drop

  • p

– Finding issued June 2014 – Inadequate oversight of contractor activities – Failure to load-test lift rig – Event exposed latent conditions (degraded flood barriers) – Narrow scope of initial Root Cause Evaluation

  • tec

ection tion

– Finding issued January 2015 – Inadequate design and maintenance of flood barrier seals – Issues not treated commensurate with safety significance – Minimal oversight of contractor-conducted post-Fukushima flooding walkdowns – Incomplete analysis of mitigating strategies

SLIDE 34

NRC Driving Licensee Actions

  • Problem evaluation weaknesses

– Root cause evaluation quality – Extent of condition reviews narrow

  • Unit 1 auxiliary feedwater pump
  • Latent Equipment Issues

– Alternate AC diesel generator failure (February 2013) – Unit 1 decay heat removal pump failure (March 2013)

Performance Assessment

  • Column 4 oversight actions are

appropriate

– Performance deficiencies associated with Yellow findings are potentially broader

  • Safe to continue power operation

– Strong operator performance – Good equipment reliability
