BOSTON EDISON COMPANY PILGRIM NUCLEAR POWER STATION Summarv of Operations for December, 1979 On December 1, the power was reduced to 50% for about 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to backwash the main condenser and to check for air in-leakage to the condenser. During this period, power was reduced to 15% for a short time due to ' vacuum problems.

Power was increased to 80% on 12/2/79 at 0800 and reached 100% power at 0800 on 12/3/79. Maintained 100% power until 12/11/79 when we started "coas t down" . Power decreased about 1% per day.

On 12/16/79, power was reduced and a control rod adjustment was made and power was returned to 98%. A recire. pump was tripped on 12/18/79 due to cable tray work, which caused a power reduction to about 60%. During this time, some miscellaneous repairs were made to 'B' R.F.P.

Power was increased to 100% on 12/20/79, but failed to stay at 100% due to end of life "coas t-down" . Power continued to reduce to 93% on 12/28/79.

Removed the 1st point heaters f rom service and the power level was 96% on 12/31/79.

The plant availability for the month was 100%. The Plant capacity factor for the month was 93.2%. The 1979 availability was 89.3%. The 1979 capacity factor was 82.55%.

The capacity factor for December was 93.2% due to the fact that power had to be reduced for condenser work.
