I BOSTON EDISON COMPANY PII.CRIM NUCI. EAR POWER STATION Summary of Operations for July, 1980 The power level was maintained at 100% until July 19, when the power was reduced to 87.4% due to a fouled condenser. The power was reduced to 50%

[ and the main condenser was backwashed. Power was increased to 90% by 0800 July 20, and continued to increase to 100% where it was maintained until 0001 on July 25.

The unit was shut down on July 25 for a planned weekend outage to perform '

i special testing on the scram discharge volume as required by the NRC.

t Miscellaneous maintenance was performed and the special testing was completed.

J "D" relief valve failed to open, during testing, prior to the shutdown. A faulty solenoid was replaced and the valve re-tested during startup.

The unit was back on line at 1136 hrs. on July 27. Power was increased to j

100% and maintained for the remainder of the month.
