Dockot Nos. 50-277/50-278 Attachment to Monthly Operating Report fo r November, 1985 Peach Bottom Atomic Power Station Narrative Summary of Operating Experiences November, 1985 UNIT 2 Unit 2 began the report period operating at full power and maintained full power operation until November 10.

On November 10, a fire occurred in a cable tray in the radwaste building.

An electrical transient (caused by the fire) caused a recirculation pump runback and a turbine electrohydraulic control system (EHC) runback, resulting in a load reduction to 770 MWe.

On November 11, the unit returned to full power and maintained full power operation until November 29.

Repairs to damaged cables were completed within a week.

Investigation into the cause of the cable tray fire continues.

On November 29, the unit was removed from service for a modification and maintenance outage to complete environmental qualification (EO) work in accordance with NRC regulations and to perform pipe support snubber inspections.

During the manual shutdown for EO work on November 29, th e reactor scrammed due to the closure of the 1, 3 and 4, turbine stop valves while attempting to close th e 2 turbine stop valve.

The 2 turbine stop valve had f ailed to close earlier the same day while being tested and was being investigated at the time of the scram.

UNIT 3 Unit 3 continued its sixth refuel outage Ebroughout the report pe riod.

On November 2, the 3C Residual Heat Removal (RHR) pump motor failed due to a fire in the lower motor guide bearing reservoir.

Guide bearing failure was caused by a pump impeller wear ring failure.

A new pump and a motor have been installed, tested, and i

placed into service.

An investigation concludes that IGSCC of the pump impeller wear ring was the cause of failure.

Weld overlay of the RHR and Recirculation System welds was completed on November 12.

On November 16, the 3A residual heat removal (RHR) pump was disassembled to replace the pump flange gasket.

During disassembly, a cracked impeller wear ring was also observed.

As j

a' result, the motor lower guide bearing was inspected, revealing signs of some damage.

The pump impeller was replaced and the motor lower gaide bearing was repaired.

The 3A motor and pump were returned to service on November 26.

Because of the problems

Attachmant to Monthly Operating Raport for November, 1985 Page 2 4

with the 3A and 3C RHR pumps, the 3B and 3D were also inspected and showed significant impeller wear ring damage.

The 3B and 3D pumps are being re naired.

On November 23, during installation of the steam separator, four of the 48 hold-down bolts broke.

Analysis of the bolt concludes IGSCC to be the cause of failure.

During removal, one of the bolts was dropped into the annulus region of the vessel, resulting in damage to a jet pump pressure sensing line inside the vessel.

Resolution of this problem is being investigated.
