Compute to the nearest whole megawatt.

These figures will be used to plot a graph for each reporting month. Note that when maximum dependable capacity is used for the net electrical rating of the unit, there may be occasions when the daily average power level exceeds the 100% line (or the restricted power level line). In such cases, the average daily unit power output sheet should be footnoted to explain the apparent anomaly.

TELEPHONE: (509) 3774448 a REPORT PERIOD: APRIL 1994 No. Date Type Hours Reason Method LER Number System Component Cause and Corrective Action To Prevent Recurrence 94%2 April 26 F 85.8 A 94-008 CB INSTRU While operating at a reduced power level (-50%),

control room operators observed slight fluctuations in

~

power range monitors. The reactor was manually scrammed as per the Abnormal Operating Procedures. An investigation into the reactor power fluctuations showed that small changes in recirc flow control valve position indication caused corresponding changes to reactor coolant fiow and reactor power. A malfunctioning valve position transmitter willbe repaired during the annual refueling outage.

94-03 April 30 S 24.0 RC FUELXX Plant officially entered the annual refueling outage (R-9) on April 30.

SU1VBCARY: WNP-2 operated near 65% power entering a forced outage at the end of the month as the result of a manual scram. The plant began the annual refueling outage on the last day of the month.
