Performance Monitoring Value PI (1 year) Confirmed – 3 trip avoidances Potential – 6 trip avoidances Equipment Abnormalities – Over 70 abnormalities monitored - - - > long term reliability System Abnormalities SmartSignal (3 months) Equipment Abnormalities - 14 identified that either returned to normal or communications to plant lead to corrective actions. - - - > long term reliability Instrumentation Issues – Over 35 identified resulting in a potential increase of plant reliability. - - - > long term reliability Efficiency - 2 efficiency catches resulting in the scheduling of a water wash and NH3 injection reduction. Culture Change PSC has noticed plant personnel are more cognizant of equipment abnormalities that are not yet urgent. Operational procedures have been modified to prevent less than optimal operational conditions.
