i PEACH BOTTOM ATOMIC POWER STATION NARRATIVE

SUMMARY

OF OPERATING EXPERIENCES October, 1981 UNIT 2 OPERATIONS Power was reduced to approximately 50% on October 9 to accommodate a control rod pattern adjustment and to remove the fifth feedwater heaters from service to improve end of life power levels.

The unit was returned to full power late on October 12.

l The reactor scrammed on October 14 during on line maintenance of an ECCS power supply.

All four power supplies were replaced to correct a 4 volt ripple in the 24 volt DC output which was causing setpoint drift in ECCS instrumentation.

The unit was returned to service on October 15.

The unit reached full power on October 19 following delays in the rise to power due to failure of the 2A condensate pump motor.

A-Loadwasreducedbyapproximately50MWeonOctoberj20 for approximately eleven hours due to high bearing vibration.

The problem was corrected by adjusting the generator hydrogen cooling water.

Load was reduced to 650 MWe on October 23, 1981 to accommodate a control rod pattern adjustment.

The unit reached full load on October 26, 1981.

During the reporting period, repairs were completed to i

the vertical drive and one cylinder of the E-4 diesel generator.

Leaks on a fuel oil injector, cooling water fitting, and emergency service water outlet bellows expansion joint for the E-3 diesel engine heat exchangers were also corrected.

The HPCI system gland seal condenser gasket was replaced during this month.

Additionally, during the period, 'a failed reactor protective system relay was replaced to correct a false "A" channel half-scram.

N A

m-e

^

UNIT 3 OPERATIONS The reactor was returned to service on October 2 following completion of the Unit 3 fourth refueling outage.

The unit was not returned to service until October 23'.

Between l

October 2 and October 23, return to service was delayed due to repairs to two turbine-generator bearings caused by insufficient lubricating oil flow, steam jet air ejector start-up difficulties, and a false condenser low vacuum scram.

Load was reduced on October 24 to accommodate overspeed trip testing of the main turbine.

The unit reached a limit of 834 power on October 30 pending correction of a high vibration problem with the 3

'B' condensate pump motor.
