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
Overall Plan & Path Forward Obtained Develop Enf./SDP Develop Completed Issue Public Alignment with strategy and long-term Tabletops Report on NRC Mgt. on Regional Panel oversight process at facilities Tabletops PCC Proposal Guidance Dec 2022 April/May 2023 2026 Feb/Mar 2023 Fall 2023 Conduct public Gather feedback Developed meeting Develop from near-term Working Group Workshop with near-term oversight, update as recommendations Tabletop oversight necessary for near-term sites/Industry guidance path forward 2024-2026 Stakeholders Summer 2023 Feb 2023 Mar 2023 2
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.

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.).

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
- 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.
