PRA Configuration Control Workshop Proposed Path Forward x
March 30, 2023 Lundy Pressley Reliability and Risk Analyst Office of Nuclear Reactor Regulation Division of Risk Assessment PRA Oversight Branch
2 Completed Tabletops at facilities Dec 2022 Conduct public meeting Workshop with Tabletop sites/Industry Stakeholders Mar 2023 Developed Working Group recommendations for near-term path forward Feb 2023 Obtained Alignment with NRC Mgt. on PCC Proposal Feb/Mar 2023 Overall Plan & Path Forward Develop near-term oversight guidance Summer 2023 Develop Enf./SDP strategy and Regional Panel Guidance Fall 2023 Issue Public Report on Tabletops April/May 2023 Gather feedback from near-term oversight, update as necessary 2024-2026 Develop long-term oversight process 2026
3 Proposal:
- Some level of oversight is appropriate to ensure the PRA is maintained over the life of the plant.
- Balanced approach of focused inspections within the existing ROP to monitor Plant/PRA changes and ensure appropriate implementation of PRA Configuration Control (PCC) programs for licensee PRA models that support risk-informed decision-making.
- The NRC Working Group has leveraged insights from the information gathered from the voluntarily performed tabletops, as well as interactions with industry and public meetings, to develop options and a draft recommendation for the PRA CC framework.
4 Evaluated Options Four options considered:
- Option 1 - Comprehensive Engineering Team Inspection (CETI)
(Internal Events, Flooding & Other Approved Hazards)
Focused Engineering Inspection (FEI) / (71111.21N)
- Option 2 - Resident Inspector Baseline Procedures. All hazards.
- Option 3 - IMC 2515 Appendix C, Infrequent Inspection.
- Option 4 - OpE Smart Sample (OpESS)
Added to current CETI/FEI/Fire/and Others as applicable (i.e., IP 37060, 71151, etc.).
5 WGs Recommended Inspection Enhancement
- Step 1 (Near-term): OpE Smart Sample (OpESS+)
PROPOSED Inspection Procedures:
71111.21M, Comprehensive Engineering Team Inspection, (CETI) 71111.21N.05, Fire Protection Team Inspection (FTPI) 37060, 10 CFR 50.69 Risk-Informed Categorization and Treatment SSC Resident Baseline: 71111 as appropriate (TBD) 71111.13, Maintenance Risk Assessments and Emergent Work Control 71111.18, Plant Modifications 71151, Performance Indicator Verification 71152, Problem Identification and Resolution (PI&R) 71153, Follow up of Events and Notices of Enforcement Discretion Focused Engineering Inspection (FEI) - None Current, Future TBD (2024-2026)
Step 1.A: Evolve/Update OpESS+ as needed.
6 OpESS+
SFCP NFPA 805 RICT 50.69 Proposed OpESS+
applicable and flexible to the Risk-Informed Initiatives in place.
Balanced and graded approach.
7 Near-term Actions - OpESS Obtained preliminary NRC Management endorsement of the WG recommendation (Complete)
Obtain and address Industry and Public Feedback (Ongoing)
Internal Communication/Awareness (Ongoing)
Training and Communication with Inspectors (Ongoing)
Finalize OpESS guidance (Ongoing)
Enforcement / Significance Determination Process
- Initiate Cross Regional Panel Process (Ongoing)
- Develop Screening Guidance (Ongoing)
- More-than-Minor/Green Threshold criteria (Ongoing)
8 Long-term Actions - ROP Update Based upon Feedback from OpESS institutionalize changes to ROP (Target 2026-2027)
Update SDP/Enforcement of PCC issues
9 Planned Outreach Efforts Issue publicly available report on insights from Tabletops Continue to engage with public and industry ROP Bi-Monthly public meetings Public workshops Industry meetings/interactions
