DAY TlHE REMARK /H00E l

02/01 0000 Unit began the month at 100% Power.

1207 Condensate Polishing Vessel 'E' partially isolated, causing a reduction in condensate /feedwater flow. Unit stabilized at 86% power.

t I

PIl0 0627 Unit began coast down for refueling outage 2RF02.

l 02/14 0832 Loss of feedwater heaters followed by automatic turbine runback due to the unexpected opening of feedwater heater bypass valve 2 PV 2286 resulting from the closing of Gland Steam Condenser (GSD) condensate bypass flow control valve 2-FV-2243 upon the removal of an associated l

controller card for calibration. Following the turbine runback, unit l

stabilized at 871 electric power. As part of corrective measure, l

issued Instrumentation & Control procedure changes'to address precautions for shared card scenario, l

l 02/23-0152 Unit began end of cycle ramp down to start 2RF02.
