Docket No. 50-352 Attachm:nt to Monthly Op3rtting Raport for December 1987 Limerick Generating Station Unit 1 December 1 through December 31, 1987 I. Narrative Summary of Operating Experiences The unit began the report period operating at approximately 100% power.

On December 8, 1987, during the performance of the quarterly HPCI Pump, Valve and Flow Surveillance Test, the auxiliary oil pump began to cycle and the stop valve began to oscillate. An investigation revealed that the mechanical overspeed trip mechanism was malfunctioning. The suspected cause of the malfunction was dirt accumulation in one of the trip mechanism's oil ports. Following flushing of the oil system and exercising the trip mechanism, the surveillance test was completed satisfactorily.

On December 24, 1987, a condensate filter demineralizer resin intrusion occurred while returning a condensate filter demineralizer to service. This resulted in reactor coolant chemistry changes and increased steam line radiation levels necessitating a power reduction to 78% power. On December 27, 1987, following reactor coolant cleanup and subsequent investigation, the reactor was returned to full power operations.

The unit ended the report period operating at approximately 100% power.

II. Challenges to Main Steam Safety Relief valves The:m were no challenges to the Main Steam Safety-Relief va: c.c during the month of December.
