OPERATIONS

SUMMARY

NOVEMBER 1990 The unit entered the month operating at -95% power producing -820 MWe gross electrical generation. The unit continued at this power level until November 28th, when a power reduction was commenced as a result of a degrading low pressure feedwater heater tube leak. Plant power was reduced to 75t. The plant closed the month operating at 75% producing 600 MWe. The "B" high pressure and low pressurs feed water heater strings were isola ed to support repairs to the "10B" low pressure feedwater heater.

MAJOR SAFETY RELATED MAINTENANCE During November, the following major safety related maintenance activity was performed:

Control Buildina chiller "A" (AH-C-4A)

The Control Du11 ding "A" Chiller (AH-C-4A) work performed during November included both the monthly and annual inspection activities. The required preventative and minor corrective ma;.r.tnnance items were completed. A Hot Gas Bypass Valve Kit was instclied as a modification to eliminate short cycling of the chillers during low-load operation. The modification was made on the recommendation of the equipment vendor. The chiller was run at low-load conditions to check the operation of the completed . Hot Gas Bypass Valve installation and satisfactory results were achieved.
