These figures willbe 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.
UNIT SHUTDOWNS AND POWER REDUCTIONS DOCKET NO.: 50-397 UNIT NAME: WNP-2 DATE: September 1; 1993 COMPLETED BY: D.G. Embree TELEPHONE: (509) 3774448 REPORT PERIOD: AUGUST 1993 No. Date Type Hours Reason Method LER Number System Component Cause and Corrective Action To Prevent Recurrence 93%7 8/03/93 F 219.5 93427 CD VALVEX During performance of a surveillance procedure to calibrate Main Steam Radiation Indicating Switch, the reactor unexpectedly scrammed &om 100%
power due to a full isolation of the MSIVs.
It was discovered that a MSIV pilot valve had been improperly rebuilt during the recent refueling outage.
It was correctly rebuilt and the plant vys eventually restarted. See LER 93M7 for other corrective actions taken and training evolutions planned.
SUMMARY
- WNP-2 had one automatic scram during the month of August. Upon completion of required equipment repairs, the plant was restarted and ramped up to full power operation by month's end.
