Key Messages Operating Experience Smart Sample (OpESS) provides maximum flexibility for regional implementation.
Cross-regional review panel process will ensure consistent application across the Regional Offices.
The WG is currently drafting the OpESS and associated guidance.
The OpESS is intended to be resource neutral and is part of the overall graded and balanced approach that will eventually determine the long-term recommendations for PRA Configuration Control (PCC),
which is targeted for implementation in the 2027 ROP inspection cycle.

What is OpESS?
OpE - Operating Experience and SS - Smart Sample = OpESS The OpESS is designed as an additional tool to be used by agency staff in ROP baseline inspection preparation.
The information and trends identified from OpESS inspections may provide further indication that a specific issue warrants additional agency action.
Each OpESS has a unique and sequential identifier.

What will the OpESS look like?
Balanced approach will ensure that inspectors only review aspects from SFCP approved and implemented risk-informed initiatives.
Performance-based in that sampling will be reviewed and adjusted annually until issuance of final 50.69 OpESS NFPA 805 recommendations.

- WG will provide inspectors with guidance (insights/specifics) on appropriate use/utilization of the OpESS.

Applicable OpESS Inspections PRIMARY 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
- 71111.06, Flood Protection Measures,
- 71111.13, Maintenance Risk Assessments and Emergent Work Control
- 71111.18, Plant Modifications (Primary)
- 71111.24, Testing and Maintenance of Equipment Important to Risk.
- 71151, Performance Indicator Verification
OpESS Proposed Details
- 1. Verify processes are in place to maintain risk-informed decisions, (i.e., new information and data).
- 2. Verify processes are in place to ensure the PRA is maintained with the as-built as operated plant.
- 3. Verify significant modifications to the plant screened for review and any needed updates to the PRA and the Model of Record.
- Guidance can be applied in 2-stages:
- 1. Forward looking (future changes) and,
- 2. Backward looking (past completed changes, e.g., last MOR change/inspection etc.).
- Intent would be to revise the OpESS for the subsequent ROP Cycle (2025) based upon observed performance (2024) and refocus, as necessary.
