Docket No. 50-352 Attachment to Monthly Operating Report for October, 1987 i

Limerick' Generating Station Unit 1 October 1, through October 31, 1987 I.

Narrative Summary of Operating Experience Unit 1 began the report period operating at 83.5% power due to turbine Electro-hydraulic Control (EHC) piping vibrations.

On October 13, while performing a surveillance test, the

'A' Recirculation Pump Breaker tripped and reactor power was reduced to approximately 25% power.

The cause of the trip is suspected to be a. spurious signal in the breaker circuitry.

Shortly after the

'A' Recirculation Pump was restarted, the

'B' Recirculation Pump tripped on low lube oil pressure.

The

'B' Recirculation Pump was restored and load was returned to 83% power.

The unit ended the month at approximately 85% power, pending i

resolution of the EHC vibration problem.

II. Challenges to Relief Valves There were no challenges to the Main Steam Safety-Relief valves during the month of October.
