Docket No. 50-352 Attachm3nt to Monthly Operating Report for March 1988 l

Limerick Generating Station Unit 1 March 1 through March 31, 1988 I.

Narrative Summary of Operating Experiences The unit began the report period operating at approximately 100% power.

On March 22, 1988, while starting the Dll Diesel Generator, for a monthly operability run, a loud bang was heard in the generator bay.

The diesel was declared inoperable and an investigation into the origin of the noise was initiated.

Maintenance inspections and testing was performed and no problems were identified.

The operability run of the D11 Diesel Generator was successfully completed and the generator was declared operable.

However, it is suspected that the noise might have occurred if the generator was synchronized slightly out of phase.

On March 25, 1988, reactor power was reduced to approximately 82% due to a weather related decrease in condenser vacuum.

I Full reactor was restored by March 26, 1988.

The report period ended with the unit operating at approximately 97% power due to main turbine backpressure limitations.

On April 8, 1988, Unit 1 is scheduled to be shut down for a two week mini outage for main condenser tube cleaning.

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