Reason 1
Method of Shutting Down Reactor2 Cause and Corrective Action to Prevent Recurrence No power reductions of greater than 20 percent during June 2002.
Summary : Unit 1 operated at 100 percent power throughout the month of June with a capacity factor of 100 percent. No PORVs or safety valves were challenged in June. A design change has been implemented on Unit 1 increasing the Design Electrical Rating and the Maximum Dependable Capacity.

4 Unit 2 remained offline at the beginning of the month because of an automatic reactor trip in May, as a result of high stator cooling water temperature. The cause of the trip was the failure of the raw cooling water supply valve to the stator cooling water system. The valve was replaced.
Summary: Unit 2 was offline at the beginning of June as a result of the unplanned automatic reactor trip in May. Unit 2 was returned to service on June 1 and reached 100 percent power on June 2. Unit 2 capacity factor for June was 96.7 percent. No PORVs or safety valves were challenged in June.
