Opening Remarks
Working Group Charter ML25125A115
Purpose Perform a comprehensive review of ROP performance indicators (PIs), which will inform a potential re-evaluation of the role of PIs in the assessment process and re-baselining of the inspection program to meet ADVANCE Act directives to review the balance of oversight and inspection resources commensurate with safety significance and licensee performance.

Initial Concepts
ROP Bases ROP bases documents prescribe risk-informed baseline inspection to cover risk-significant cornerstone attributes of performance not adequately covered by PIs, plus:
- Verification of PI data
- Comprehensive review of corrective action program/problem identification and resolution
- Event response
Gain Efficiency
- Can we increase the use of performance indicators to reduce the resources required for inspection?
- Is there a role for performance-based indicators that inform baseline samples without action matrix movement?
- Can we create a framework with indicators that can (also) apply to new and advanced designs?
- Is there an opportunity to incorporate plant-specific design and risk factors into new indicators?
Gain Efficiency
- Can we leverage indicators and data that licensees already compile?
- Can we minimize/eliminate the need for the FAQ process?
- Is there a path to streamline the data submission process?
- Can we make use of programs that are already in broad use (Maintenance Rule, Corrective Action Program etc.)?
Caveats
- Need to ensure coverage of cornerstone attributes (Inspection Manual Chapter 0308, ADAMS ML24269A231)
- Program requires flexibility to adjust based on lessons learned and emerging trends
- Accurate data submission essential for program integrity
- Inspection for verification
- Potential inspection samples for anomalous data submissions
