SUMMARY

Unit 2 began the month of February operating at - 2700 CMWT with end of cycle coastdown in progress.

On February 04 with the unit at -2663 CMWt, the shift began a power reduction to allow the unit to begin its 18th refueling outage. The unit entered the 18th Refueling Outage when the Shift manually tripped the Main Turbine on February 05, after which a Main Turbine overspeed trip test was performed. Later that day, the shift inserted a manual scram to enter mode 3. Shift began fuel offload on February 10. The initial fuel offload was completed on February 12.

The Shift began core reload activities on February 25. Outage activities continued for the remainder of the month.

There were no challenges to the safety relief valves.
