CAUSE/CORRECTIVE ACTION/COMMENTS:

NARRATIVE REPORT Unit 1 began the month of November operating at rated thermal power. Shift reduced load to approximately 790 GMWe (-2485 CMWr) on November 1 to perform control rod drive exercises. The unit was returned to rated thermal power on November 2. Shift reduced load to approximately 865 GMWe (-2625 CMWT) on November 8 to perform main turbine valve testing, then further reduced load to approximately 805 GMWe (-2485 CMWM) and performed control rod drive exercises. The unit was returned to -99.5% of rated thermal power on November 9. Shift reduced load to approximately 755 GMWe (-2350 CMWT) on November 16 to perform control rod drive exercises, then further reduced load to approximately 555 GMWe (-1795 CMWT) on November 17 to perform scram time testing and a rod pattern adjustment. The unit was returned to rated thermal power on November 18. Shift reduced load to approximately 815 GMWe (-2515 CMWT) on November 19 after power was momentarily lost to the fans on the Helper Cooling Tower, due to a failed transformer. The fans cycled back on as designed and the unit was returned to rated thermal power on November20. Shift reduced load to approximately 810 GMWe (-2485 CMWT) on November22 to perform control rod drive exercises. The unit was returned to rated thermal power on November 23. The unit dropped below rated thermal power on November 25 due to the current control rod pattem. Shift increased reactor power to approximately 99.7% of rated thermal on November 27 after the high speed stops were reset on the reactor recirculation system. Shift reduced load to approximately 810 GMWe (-2485 CMWT) on November 29 to perform control rod drive exercises. The unit was returned to approximately 99% of rated thermal power on November 30. Reactor power was at approximately 98.5% of rated thermal at the end of this reporting period and will continue to "coastdowne due to the current rod pattern.

CAUSEICORRECTIVE ACTION/COMMENTS:

NARRATIVE REPORT Unit 2 began the month of November operating at approximately 98.5% of rated thermal power due to concerns with the flow margin on the #4 main turbine control valve. Shift reduced load to approximately 875 GMWe (-2635 CMWT) on November 2 to perform control rod drive exercises. The unit was returned to -98.5% of rated thermal power later the same day. Shift reduced load to approximately 880 GMWe (-2635 CMWT) on November 9 to perform control rod drive exercises. The unit was returned to -98.5% of rated thermal power on November 10. Shift reduced reactor power to approximately 97% of rated thermal on November 14 due to the unreliability of the process computer core thermal power program. The unit was returned to -98.5% of rated thermal power on November 15. Shift reduced load to approximately 870 GMWe (-2635 CMWT) on November 17 to perform control rod drive exercises. The unit was returned to -98.5% of rated thermal power on November 18. Shift increased reactor power to approximately 2777 CMWr on November 18 for Appendix K Power Uprate Testing. The unit was returned to -98.5% of rated thermal power later the same day. Shift reduced load to approximately 855 GMWe (-2555 CMWT) on November 19 after power was momentarily lost to the fans on the Helper Cooling Tower, due to a failed transformer. The fans cycled back on as designed and the unit was returned to -98.5% of rated thermal power later the same day. Shift increased power to approximately 2777 CMWT on November 21, which is the maximum operating power (MOP) established from results of the Appendix K Power Uprate Testing. Shift reduced load to approximately 565 GMWe (-1795 CMWT) on November 22 to perform a control rod sequence exchange, scram time testing, and turbine control valve testing. The unit was returned to MOP on November 23.

Shift reduced load to approximately 680 GMWe (-2105 CMWT) on November 23 to perform control rod drive exercises and maintenance on selected condensate demineralizers. The unit was returned to MOP on November 24. Shift reduced load to approximately 850 GMWe (-2520 CMWT) on November 25 to perform a rod pattern adjustment. The unit was returned to MOP on November 26. Shift began reducing power to approximately 94% of rated thermal on November 30 to perform control rod drive exercises. The power reduction was still in progress at the end of this reporting period with the unit at approximately 94.2% of rated thermal.
