50-301 UNIT NAME Point Beach, Unit 2 DATE January 9, 1991 COMPLETED BY J.

W. Jack TELEPHO!,'E 414/755-2321 Unit 2 operated at approximately 500 MWe not thrcughout this report period with the following load reductions:

December 2 Power was reduced to 469 MWe for condenser steam dump testing.

l Power was reduced to 369 MWe for turbine stop December 9 valve testing.

December 13 -

Power was reduced to 200 MWe in response to inadvertent actuation of relay 2ClaX.

An operator accidentally bumrv? containment pressure concensate isolattun relay 2CPAX while attempting to verify wiring in a control board.

The relay in turn tripped the condensate pumps and heater drain tank pumps.

Operators promptly responded by initiating a manual runback from 100 percent to 38 percent power and restarting the condensate the heater drain tank pumps prior, thereby preventing a unit trip.

December 20 -

Power was reduced to 295 MWe to repair condensate pump B.

Safety-related maintenance included the following:

Corrosion repaired on cooling water supply lines to the turbine-driven aux 311ary feedwater pump.
