80STON'EDIS0N COMPANY-j PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293' Oper3tional Summary for Auaust 1992 JThe unit started the reporting period at approximately 100 percent core thermal' power (CTP).

Reactor power was lowered several times'during August 5 through 8 to stab "ize condenser 3ccuum, and on August 8 reactor power was reduced to approximately 45 percent to facilitate-a main-cordenser backwash.

Following the successful backwash power was increased to 100 percent at approximately 0700 Sours on August o.

Power was maintained at approximately 100 percent until August-21 when at ?040 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> R culation' pump 'A'-
