SUMMARY
- Unit 1 began the month of December operating at rated thermal power. Shift reduced load to -835 GMWe (-2520 CMWt) on December 5 to perform CRD Stall Flow Testing, Turbine Stop Valve Testing and make a minor Rod Pattem Adjustment. The unit was returned to rated thermal power later that day. Shift reduced load to
-930 GMWe (<2790 CMWt) on December 11 due to loss of the process computer and the Core Thermal Power (CTP) program. The unit was returned to rated thermal power later that evening. Shift reduced load to -890 GMWe (-2650 CMWI) on December 18 to perform a minor Rod Pattern Adjustment and returned the unit to rated thermal power approximately 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> later. Unit 1 completed the month of December operating at rated thermal power. There were no challenges to the safety relief valves.

SUMMARY
- Unit 2 began the month of December operating at 2790 CMWt, Maximum Operating Power (MOP).
Shift reduced load to -835 GMWe (-2520 CMWt) on December 5 to perform CRD Stall Flow Testing, Turbine Stop Valve Testing, and make a minor Rod Pattern Adjustment. The unit was returned to MOP later that day. Sift reduced load to -785 GMWe (-2300 CMWt) on December 12 to make a Rod Pattern Adjustment and began power ascension to MOP a few hours later. Shift halted the power ascension for approximately one hour on December 13 to investigate a high level alarm on the 4th Stage "B' Feedwater Heater. Shift resumed power ascension after it was determined the normal level control valve was not functioning properly and the heater level control was being maintained by the high level control valve. The unit attained MOP a short time later on December 13. Shift reduced load to -660 GMWe (-2050 CMWt) on December 19 to perform Turbine Control Valve Testing and repair the positioner for the normal level control valve to the 4th Stage "B" Feedwater Heater. The unit was returned to MOP early on December 20 with the normal level control valve for the 4th Stage "B" Feedwater Heater operating properly.
Shift reduced load to -660 GMWe (-2050 CMWt) on December 22 to perform a Rod Pattern Adjustment and fully open the throttled MSR 2nd Stage Scavenging Steam Vent Valves to allow for completion of the Appendix K Power Uprate. The unit was returned to MOP early on December 23. Later that day Shift increased power to 2804 CMWt, verifying that opening the MSR 2nd Stage Scavenging Steam Vent Valves provide sufficient margin to attain rated thermal power. The unit was returned to MOP a few hours later. Shift reduced load to -880 GMWe (-2660 CMWt) for a minor Rod Pattern Adjustment late on December 23. Shift returned the unit to MOP early on December 24. Unit 2 completed the month of December operating at MOP. There were no challenges to the safety relief valves.
