PEACH BOTTOM ATOMIC POWER STATION NARRATIVE

SUMMARY

OF OPERATING EXPERIENCES APRIL 1981 Unit 2 The Unit operated at full power until early April 20 when an orderly shutdown was begun as a result of two Core Spray pumps failing to meet the Inservice Inspection operability criteria during a scheduled surveillance test. The Unit was returned to full power later on the same day following recalibration of tne Core Spray punp flow indicator and retesting of the pumps.

Early on April 22, load was reduced to 800 MWe to verify a load relationship with a high " combustibles" indication on the 2A phase main transformer. The Unit was removed from service later in the day following the failure of the 28 recirculation pump seal. Subsequently, the 2B recirculation pump motor bearing was found to be badly damaged. The unit remains shutdown to effect repairs to the 2B recirculation pump motor.

Unit 3 The Unit remains shutdown'to accommodate refueling, modifi-cations and maintenance work. The Torus has been drained, decontaminated and structural modifications are in progress.

During blocking for Emergency Core Cooling System (EECS) sensor replacement, a false ECCS initiation signal was received which led to draining of 160,000 gallons of water from the Unit 3 condensate storage tank into the Unit 3 High Pressure Coolant Injection (HPCI) pump room via the pump suction line and the disassembled pump. Flooding of this room also caused a spurious initiation of the CO, fire protection for the room.

There were no resultant personnel exposures or injuries.

The Feedwater Spargers have been removed and the machining of the reactor vessel feedwater nozzles has begun. Changeout of Control Rod drives continues.
