BOSTON EDISON COMPANY PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293 Operational Summary for March 1985 The month commenced with the unit.at 100% power which was maintained until the ninth when power was reduced for a condenser backwash and maintenance on the "B" travelling screen. Subsequent to completion of these tasks, the unit was returned to-100% power on the tenth and maintained at that level until the fifteenth.

On the fifteenth, a reactor scram occurred during surveillance testing of the reactor water level safeguards system (Ref.: LER 85-006). While shut down, maintenance was performed on the reactor water sample system and secondary containment dampers (Ref.: LER 85-007).

Upon completion of maintenance activities, the unit was returned to service on the twentieth at approximately 0830 hours0.00961 days <br />0.231 hours <br />0.00137 weeks <br />3.15815e-4 months <br />. Power was steadily increased to an average daily level of 100% by the twenty-third and maintained at that level until the end of the month.
