BOSTON EDISON COMPANY PILGR1M NUCLEAR POWER STATION DOCKET NO. 50-293 Operational Summary for Feburary 1986 t,

The month commenced with the unit at full power. Power was reduced to an average daily level of 97% on the third in response to inoperable isolated phase bus y cooling fans. From the fourth through the fifteenth, the unit was operated between

, 99% and 100% power.

3 On the sixteenth power was reduced to an average daily level of 64% to backwash the main condenser and perform a control rod pattern change. Power level was increased on the seventeenth and from the eighteenth through the twentieth was maintained between 99% and 100%. At approximately 2330 hours0.027 days <br />0.647 hours <br />0.00385 weeks <br />8.86565e-4 months <br /> on the twentieth a controlled shutdown was initiated in response to the standby liquid control system being  !

potentially inoperable. This reduced the average daily power level to 98%. The l shutdown was terminated on the twenty first and from the twenty first through the end of the month the unit was operated between 99% and 100% power.

An unusual event was declared on 2/14/86, when the "A" emergency diesel and a LPCI injection valve were simultaneously out of service for approximately two hours.
