Performance Monitoring Value– PI (1 year)
• Confirmed – 3 trip avoidances• Potential – 6 trip avoidances• Equipment Abnormalities – Over 70 abnormalities monitored - - - > long term reliability
– 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.
