Power was returned to 100%

within one hour. The plant operated the remainder of the month at 100% power producing approximately 870 MWe.

i MAJOR SAFETY RELATED MAINTENANCE During June, the following major maintenance activities were performed on safety-related equipment:

Feedwater System Vent Valve (FW-V-55A)
