SUMMARY

OF OPERATING EXPERIENCES Limerick Unit 1 began the raonth of September at 100% of rated thermal power. On Friday, September 4, reactor power was briefly reduced to 92% of rated to perform Main Turbine Control Valve testing. On Sunday, Septembar 13, power was bri e fly reduced to 97% to support a Control Rod pattern adjustment. On Wednesday, September 3 0, the Sodium 24 Tracer Test results were entered into the Plant Process Computer, resulting in a reactor power adjustment of approximately 1.36%

equating to a 14.9 Megawatt electric DIWe) output gain. Unit 1 ended this operating period at a nominal 100% of rated thermal power.

II. CHALLENGES TO MAIN STEAM SAFETY RELIEF VALVES There were nm challenges to the Main Steam Safety Eelief Values during the month.

3921.048250 Docket No. #50-353-Attachment.to Monthly Operating Report for September 1S92 LIMLAICK GENERATING STATION UNIT 2 SEPTEMBER 1 THROUGH LOPTEMBER 30, 1992 I. NARRATIVE SUMMARi OF OPERATING EXPERIENCES Limerick Unit 2 began the month of September at a nominal 100%

of rated thermal power. On Friday, September 4, reactoc potar was reduceJ t, >2% to support Main Turbine Control Valve testing. On Saturday, September 5, reactor power was further reduced to 75% to perform Flux- Tilt testing and to locate / repair a tube leak in the Main Condenser Circulating-Waterbox. Reactor power was restorod to a nominal 80% on the same day. On Sunday, September 13, power ascension began, power ascension was held at 90% briefly for Condensate Demineralizer regeneration, and then briefly held again at 96.9% due to stalling of the Plant Process Computer printer, C'n Monday, September 14, reactor power ascension was completed at a nominal 98% of rated. On Friday, September 18, power was briefly reduced to 90% to support Reactor Feed Pump Turbine

'I t ip Testing, reactor powec was restored to 96.5% with increc aed core flow. On Saturday, September 19, power was briefly reduced to 90% to support Control Rod pattern adjustment. On Monday, Septerrber 21, the end of full power life was reached. On Wednesday, September 23, power was reduced to 94% to begin tube leak location / repair in t-he -"2B" Main Condenser Circulating WaterBox. On September 25, pcwer was returned to 97% until September 28, w.en power was reduced to 89% to again suppcrt Helium Leak Testing in the "2Ac . Main Condenser Cire. Waterbox. _ Unit 2 remained at a nominal 89% of rated thermal power through the end of this operating period.

Unit 2 occurrences during this operating period included.

On Friday, September 11, Reactor Engineering flux tilt testing successfully identified reactor control cell 38-07 as .the respective control cell containing degraced (leaking) fuel.

End-of-cycle control rod patterns were adjusted accordingly to minimize offgas radiation rates.

II. CHALLENGES TO MAIN STEAM SAFETY RELIEF VALVE 3 There were no challenges te the Main Steam Safety Relief Valves during the month.
