SUMMARY
The unit underwent power ascension testing in early June following a planned refueling outage. The unit reached 100% Rated Thermal Power (RTP) on June 40h. There was a planned reduction in power on June 1St in support of an SG chemistry cleanup, which required the unit to be off line. The unit was also forced to downpower to repair a steam leak. This yielded an availability factor of 98.5 % and a capacity factor of 93.2 % based on the MDC value of 1155.3 Net MWe.
