TELEPHONE: (509) 3774448 REPORT PERIOD: APRIL 1995 Date Type Hours Reason Method LER Number System Component Cause and Corrective Action To Prevent Recurrence 95-04 4/5/95 F 152.4 A 95-006 HA INSTRU Relay failure caused turbine trip and automatic scram during monthly surveillance testing. Relay replaced.

95-05 4/22/95 S 206.0 C N/A RC FUELXX Plant entered annual refueling and maintenance outage (R-10) on April 22.

SUMMARY

At the beginning of the month the plant was operating at full power. Qn April 5, the plant experienced an automatic scram resulting in about'6 days of forced outage. Following the forced outage, the plant restarted and operated an additional 11 days then plant shutdown for the annual refueling outage on April 22.

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.
