RIC 2005 SESSION W-F3 EXPANDING THE BENEFIT OF PIs A Licensees Perspective Bill Mookhoek Sr. Staff Licensing Engineer STP Nuclear Operating Company March 9, 2005
2 A Licensees Perspective
- Performance Indicators are de facto Performance Standards
- Licensees do not willingly accept crossing the Green-White threshold
- Plant generated indicators require action prior to crossing the NRC threshold
3 Station Specific Thresholds Example - AFW which has an NRC white threshold of 2.0%
a) Station Green - <1.0 b) Station White - 1.0 - 1.5 c) Station Yellow - 1.51 - 2.0 d) Station Red - >2.0 AND NRC WHITE Actions are required for declining performance
4 Using Industry Trends
- Trend plant performance against industry performance
5 Communicate Declining Performance NRC CORNERSTONE NRC INDICATOR SITE PERFORMANCE SCRAMS SCRAMS WITH LOSS OF NORMAL HEAT REMOVAL
INITIATING EVENTS UNPLANNED POWER CHANGES EDG UNAVAILABILITY
HPSI UNAVAILABILITY
AFW UNAVAILABILITY
RHR UNAVAILABILITY
SAFETY SYSTEM FUNCTIONAL FAILURES
RCS ACTIVITY
BARRIER INTEGRITY RCS LEAKAGE DRILL/EXERCISE PERFORMANCE
DRILL PARTICIPATION EMERGENCY PREPAREDNESS
ALERT NOTIFICATION SYSTEM PERFORMANCE
OCCUPATIONAL EXPOSURE CONTROL
RETS/ODCM OCCURRENCE
6 Recognizing Opportunities Licensee sponsored meeting to review performance indicators every 2 years
- Discontinue those of diminished benefit
- Forum to suggest industry areas to investigate development of new indicators which can substitute for inspection Open to Change the Process
- Risk informed indicators
- Indicator with no threshold
7 Conclusions
- Performance Indicators are Performance Standards
- Resources expended should result in a real benefit to the regulator, the public, and the industry
- Use performance indicators to compare station to industry performance
