Compute to the nearest whole megawatt.

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 ofthe 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.

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 fullisolation of the MSIVs.

It was discovered that a MSIVpilot 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 ofAugust. Upon completion ofrequired equipment repairs, the plant was restarted and ramped up to fullpower operation by month's end.
