3921066460 Docket No. #50-352 Attachment to Monthly Operating Report-for November 1992 LIMERICK OENERATING STATION UNIT 1 NOVEMBER 1 THROUGH NOVEMBER 30, 1992 I. NARRATIVE

SUMMARY

OF OPERATING EXPERIENCES Limerick Unit 1 began the month of November at a nominal 100%

of rated thermal power. On Thursday, November 5,. reactor power was reduced to 80% for control rod scram time testing and control valve testing. Reactor power was restored to 100%

of rated on Friday, November 6. On Friday, November 27, per the load dispatcher's request, reactor power was reduced to 88% rated thermal power due to excess generating capacity.

Reactor power was restored to 100% of rated on the same day.

Unit 1 ended this operating period at a nominal 100% of rated thermal power.

II. CHALLENGES TO MAIN STEAM SAFETY R* LIEF VALVES There were no challenges to the Main Steam Sa Nty Relief Valves during the month.

SUMMARY

OF OPERATING EXPERIENCES Limerick Unit 2 began the month of November in end-of-cycle coastdown at a nominal 91% of rated thermal power with core flow maximized. On Thursday, November 5, reactor power was reduced to 81% RTP to obtain a symmetric rod-pattern for Local Power Range Monitor calibrations. Reactor power was restored to 88% of rated on Monday, November 9. On Friday, November 20, at 0127 hours0.00147 days <br />0.0353 hours <br />2.099868e-4 weeks <br />4.83235e-5 months <br /> an Electro Hydraulic Control (EHC) leak was discovered on the #3 main turbine control valve. The main turbine was tripped at 0411 hours0.00476 days <br />0.114 hours <br />6.795635e-4 weeks <br />1.563855e-4 months <br /> and'the reactor remained critical on bypass valves with power a' 23% of rated. The main turbine was placed on-line at 025F hours on November 22, following repairs to the EHC piping. Reactor power was restored to 84% of rated by 1750 hours0.0203 days <br />0.486 hours <br />0.00289 weeks <br />6.65875e-4 months <br /> on November 22. Unit 2 ended this operating period at a nominal 79% of rated thermal power, in end-of-cycle coastdown with core flow maximized.

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