SUMMARY
- The unit began the month of October at a nominal 100% power level. On October 28, at approximately 00:08, a small (5 MWe) unplanned power reduction occurred. This was caused by a failure of an electrical component in the integrated control system. Power level was restored to nominal full power at approximately 05:05 on the same day, and remained there for the remainder of the month. There were neither planned nor unplanned power level changes of > 20%
during the month.
