  1. Jim HillNuclear Management Company Nuclear Plant Operation under NRC Reactor Oversight Program

  2. Prairie Island Nuclear Generating Plant Safe – Reliable – Predictable – Leader

  3. Adapted from: EED-99-01 Recommendations for the Implementation of Selected Leading Indicators of Performance at Nuclear Power Production Plants, ASQ, 1999

  4. Recognition of Need to Improve • NRC performance determination previously implemented by Systematic Assessment of Licensee Performance (SALP) • In late 1994 NRC conducted in-depth review of SALP process. Issues noted: • Lagging…consequences initiated late, sometimes after performance decline had already been turned • Inconsistent regulatory response • Determination sometimes driven by upper management bias with incomplete data Bottom Line: The process the NRC used to determine licensee performance needed to be more effective

  5. Revised Reactor Oversight Process Developed with input from plant owners/operators, facilitated by NEI • Baseline Inspection • Finding Significance Determination Process (GreenRed) • Performance Measures • Performance thresholds established (GreenRed) • Reported on a quarterly basis • Measures “rolled up” with inspection results for periodic performance assessment • Regulatory Response matrix • Additional and more intrusive Inspection • Continued degradation in performance leads to shut down Piloted at 8 nuclear plants prior to full industry use

  6. Positive Results • Industry Performance in areas measured has improved • Rigorous process for performance measures • Ensure current measures are adequate and provide value • Predictable Regulator Action • Data Driven • Accuracy of performance data has improved • Problems found early on in data reporting • NRC cannot accomplish performance-based oversight without accurate data…poor reporting is serious issue • Periodic review and improvement to ROP is ongoing. • Moving to a new set of equipment performance measures • Adequacy of Security and facility protection from external threat continues to be a priority
