Monthly summaary STPEGS Unit 2 began the reporting period operating at approximately 87%

reactor power with ascension to 100% in progress following recovery from a '

reactor trip on 3/28/95. The unit achieved full power on 4/1/95 at 0338.

On 4/3/95 at 1936 reactor power was reduced to 75% to allow repair of an electro-hydraulic control oil leak on the low pressure governor valve actuator of Steam Generator Feedwater Pump Turbine 22. Maintenance was completed and the unit was returned to full power on 4/4/95 at 0307.

The unit operated for the remainder of the reporting period with no unit shutdowns or significant power reductions.
