Narrative Summary of Operating Experiences The unit began the report period operating at approximately 85% power.

On May 3, 1988, 90% reactor power was achieved and was limited due to concerns about a fuel leak.

On May 7, 1988, a Reactor Protection System (RPS) half-scram signal and various-Nuclear Steam Supply Shutoff (NSSSS) isolations occurred due to the failure of a 60 amp fuse.

Recirculation Pump temperature increased as a result of the isolation of the Drywell Chilled Water and Reactor Enclosure Cooling Water systems.

Reactor power was reduced to 80%

until normal cooling could be restored.

The fuse was replaced, the isolations reset, and the plant systems were returned to normal.

The unit ended the report period operating at approximately 90% power limited by the fuel leak concern.

II. Challenges to Main Steam Safety Relief Valves There were no challenges to the Main Steam Relief valves during the month of May.
