• BOSTON EDISON COMPANY PILGRIM NUCLEAR POWER STATION Summary of Operations for Januarv , 1981 The month of January began with the unit operating at 100% reactor power. The unit operated at 100% thru January 4th when a unit reduction to 50% power was conducted to repair brushes on A & B reactor recircula-tion motor-generator sets and other minor maintenance. The unit was returned to 100% power and operated at this level until January 18th.

On January 18th the unit power was reduced to 50% power to back-wash the main condenser and bypass the "B" Low Pressure Heater Train.

During this power reduction, a 3b" crack was identified in the 1-2 waterbox (Main Condenser) outlet piping. Power increase was commenced and unit returned to 80% on January 19th.

Problems with control of level in the "B" Low Pressure Heater Train limited reactor power to 80% until January 22nd. On January 23rd, feedwater heaters were returned to service and unit power reached 100%

on January 23rd. Shortly af ter reaching 100%, increased leakage in the 1-2 outlet piping necessitated a power reduction to 55% to remove the waterbox.

Power was increased to 100% on January 24th and continued to operate at this power until 1125 hours0.013 days <br />0.313 hours <br />0.00186 weeks <br />4.280625e-4 months <br /> on January 28th. At this time, the reactor scrammd due to surveillance testing of Reactor High Water Trip. The unit war; started up and synchronized to the grid @l506 hours on January 29th. Power was increased to 75% and limit'ed to that power for the remainder of the month because "B" Low and High Pressure Heater Trains were isolated.
