I OPERATIONS The plant began the month at 100% power, generating 1138 MWe gross.

+

' A. reactor trip was experienced on August 9th at 1647. The trip was caused by the north main feed pump thrust bearing wear

' detector. The' reactor was taken critical on August 10th at 2216

~

'and the turbine generator snychronized to the grid on August j

t lith at 1043.

The plant _ returned to 100% power and. generated there until-August 25th when plant power was reduced to 90% for turbine valve testing.-

L

.t The plant was returned to ;00% power af ter the turbine valve
