PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293 Operational Summary for May, 1983 The unit was operating at 100% power at the start of the month.

.On May.4th, the "A" SGTS was made inoperable for maintenance and the "A" i

- emergency diesel generator fuel booster pump belt broke during surveillance and was returned to service the same day. (Ref: LER 83-23/03L-0). The "A" SGTS was made operable on May 6th, the "B" SSW loop was made inoperable for maintenance and power was reduced to 50% for a short period for a condenser backwash. On May 7th, the "B" SSW loop was made operable. On May 8th, the RCIC was taken out of service for a short period to check calibration of a flow indicator. The unit was operated at 100% until May 15th when power was reduced for a. condenser backwash with a return to 100% the same day.

r On May 18th, the "B" diesel generator fuel booster pump belt broke during scheduled surveillance (Ref: LER 83-028/03L-0). A crack was found in an ex-pansion joint on the "B" train 5th point heater.

On May 20th, power was reduced to backwash the condensers. The "A" SSW loop was taken.out of service on May 26th to replace a drain valve and was placed back in service the same day. On May 27th, power u s reduced for a condenser backwash with a return to 100%'the same day. The HPCI system was taken out of service on May 28th to repack A0-2301-31 valve, because of a steam leak.

The system was returned to service the next day. The unit ended the month at 100% power.

NOTES:

1.

The condansers were required to be backwashed every weekend because of an influx of horseshoe crabs.

2.

Reactor pressure is limited to 1025 psig because of safety /

relief valve simmer margin considerations.-
