Docket No. 50-352 Attachment _to Monthly Oparating Report for June, 1988 Limerick Generating Station Unit 1 June 1 through June 30, 1988 I.
Narrative Summary of Operating Experiences The unit began the report period operating at approximately PO\\ power limited by a fuel rod leak.
On June 7, 1988, reactor power was further reduced and maintained at approximately 85% due to an increase in condenser offgas activity caused by the fuel rod leak.
On June 10, 1988 reactor power was reduced to approximately 65% when a failure of the "5C" feedwater heater level controllers caused a reduction in feedwater hercing and an unexpectcd increase in core reactivity.
The ' 5C" level controllers were repaired and the unit was ristored to approximately 85% by June 12, 1988.
On June 13, 1988, while attempting to stcrt the "lB" Reactor Enclosure Circulating Water (RECW) pump, an electrical arc occurred damaging a MCC bus bar and tripping the supply breaker to the MCC.
This loss of power resulted in the inoperability of the "D" RHR loop, "B" RHRSW loop, "D" Core Spray pump, "B"
Post-LOCA recombiner, and various primary containment isolation valves.
Power was restored and the systems were declared operable within 55 minutes.
No load reduction was experienced as a result of this event and the bus bar was replaced by June 15, 1988.
The Unit ended the report period operating at app 3 6ximately 85% power limited by a fuel rod leak.
II. Challenges to Main Steam Safety Relief Valves There were no challenges to the Main SteE. Relief valves during the month of June.
