Developed Conduct public Gather feedback Working Group meeting Develop from near-term recommendations Workshop with near-term oversight, update as for near-term Tabletop oversight necessary path forward sites/Industry guidance 2024-2026 Feb 2023 Stakeholders Summer 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.

3 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.).

4 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 W ork 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.

5 Proposed OpESS+
