Docket No. 50-352 Attachment to Monthly Operating Report for July 1994 Limerick Generating Station Unit 1 July 1 through July 31, 1994 I.

Narrative Summary of Operatina Exneriences Unit 1 began the month of July at a nominal 100% of rated thermal power (RTP).

Power was reduced a number of times during the month of July as a result of high turbine backpressure.

On July 9, 1994, at 0020 hours2.314815e-4 days 0.00556 hours 3.306878e-5 weeks 7.61e-6 months power was reduced for condenser maintenance activities and to perform other testing activities.

Power was reduced to 75% RTP.

At 0104 hours0.0012 days 0.0289 hours 1.719577e-4 weeks 3.9572e-5 months on July 10, 1994, power was restored to 100% RTP.

On July 29, 1994, at 1342 hours0.0155 days 0.373 hours 0.00222 weeks 5.10631e-4 months the

'C' Reactor Feed Pump (RFP) tripped off.

This resulted in an automatic Reactor Recirculation Pump runback.

Power was stabilized at 80% RTP at 1348 hours0.0156 days 0.374 hours 0.00223 weeks 5.12914e-4 months .

The cause of this event was that a housekeeping individual changing lights inadvertently hit the mechanical trip lever on the feedpump local panel.

The

'C' RFP was returned to service at 1520 hours0.0176 days 0.422 hours 0.00251 weeks 5.7836e-4 months and power was restored to 100% RTP at 1645.

Unit 1 ended this operating period at 100% of RTP.

II.

Challences to Main Steam Safety Relief Valves There were no challenges to the Main Steam Safety Relief Valves during the month of July.
