BOSTON EDISON COMPANY PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293 OPERATIONAL

SUMMARY

FOR JULY 1994 The unit started the reporting period at 100 percent core thermal power (CTP) where it was essentially maintained until July 9, 1994.

On July 9, 1994 at approximately 2300 hours0.0266 days <br />0.639 hours <br />0.0038 weeks <br />8.7515e-4 months <br /> the plant commenced a power reduction to 50 percent CTP to facilitate a backwash of the main condenser.

Following completion of the backwash a power increase was commenced, and at 0637 hours0.00737 days <br />0.177 hours <br />0.00105 weeks <br />2.423785e-4 months <br /> on July 10, 1994, the plant attained 100 percent CTP where it was essentially maintained until July 17, 1994.

On July 17, 1994, power was briefly reduced to approximately 98 percent CTP in response to problems with the " EPIC Computer".

On July 19 and 20, 1994, unusually high inlet water temperature adversely affected main condenser back pressure, requiring the plant to trim power to maintain adequate vacuum in the main condenser.

At 1914 hours0.0222 days <br />0.532 hours <br />0.00316 weeks <br />7.28277e-4 months <br /> on July 20, 1994, the plant attained 100 percent CTP where it was essentially maintained throughout the remainder of the reporting period.
