SUMMARY

FEBRt1ARY 1996 Oyster Creek operated the first 16 days of February at full power. On February 17, power was reduced to 60% for 1I hours while a temporary fan was installed in the trunnion room for the disabled 1-7 fan. On February 20 at 0722, operators reduced power to 70% to allow leaking tubes in the C-South Condenser to be identified and plugged. The plant returned to full power operation on February 24 at 1535. Failure of a circulating water valve, V-3-14, motor operator forced plant power to be reduced to 70% for periods on February 25 and 26. Aller replacement of the motor operator on February 26, the plant returned to full power. Full power operation continued for the remainder of the month.

The plant generated 422,590 MWh net electric which was 98.1% ofits MDC rated capacity for the month.

?

APRM Channel 2. Upon investigation the recirculation flow signal for APRM 2 was readin 117% while the flow signal for the other seven channels read approximatel 98%. Maintenance was performed on APRM 2 on January 2, 1996, and th channel was declared operable.

A subsequent review of records revealed that inadequate post maintenance i testing had been performed on APRM 2 following a component replacement.

APRM 2 was believed to be operable but was not. Also revealed was APRM i had been bypassed for maintenance during this time period. This combination l exceeded the allowed out of service time for two APRM channels in the same i Reactar Protection Trip System. )
