SUMMARY
- Unit 1 began the month of March operating at rated thermal power (2804 CMWt). Shift reduced load to approximately 903 GMWe (-2720 CMWt) on March 19 to perform a rod pattern adjustment. Unit 1 was returned to rated thermal power on March 20. Shift maintained unit operation at rated thermal power for the remainder of the month. There were no challenges to the safety relief valves.

SUMMARY
- Unit 2 began the month of March with continuation of its 18th Refueling Outage. Core reload was completed on March 1. Shift brought the reactor critical on March 12, and then tied the main generator to the grid on March 14. Power ascension to rated thermal power was stopped at approximately 522 GMWe (-1660 CMWt) on March 15 to repair 2B reactor feed pump. Power ascension resumed on March 16, but was stopped at approximately 840 (-2550 CMWt) on March 17 to repair 2A condensate booster pump. Shift reduced power to - 700 GMWe (-2170 CMWt) later on March 17 to perform a rod pattern adjustment. Power ascension began late on March 17, and was stopped at -896 GMWe (-2690 CMWt) for current rod pattern. Shift reduced load to -835 GMWe (-2515 CMWt) on March 18 to perform a rod pattern adjustment. Shift continued power ascension and reached maximum operating power of -932 GMWe (-2787 CMWI) on March 19. Shift reduced load to -880 GMWe (-2635 CMWt) on March 20 to perform a rod pattern adjustment, and ramped to maximum operating power early on March 20. Shift reduced load to
- 890 GMWe (-2660 CMWt) on March 22 to perform a rod pattern adjustment. Shift ramped the unit to maximum operating power early on March 23. Shift raised the unit to 100% rated thermal power (-2804 CMWt) on March 24.
Shift reduced load to -835 GMWe (-2515 CMWt) on March 27 to perform control rod drive exercise and main turbine stop valve testing. Shift reached 100% rated thermal power on March 28. Shift continued unit operation at rated thermal power for the remainder of the month. There were no challenges to the safety relief valves.
