Adjusted.95%8 8/11/95 F 236.0 A NA CH INSTRU 1)Mechanical linkage loose/out of adjustment on feedwater pump turbine speed control.Adjusted.2)Wiring/coil degradation within the actuator of the governor control system.Replaced with refurbished unit.

SUMMARY

At the beginning of the month, the plant was operating at full power.While conducting monthly turbine valve testing, the plant experienced main turbine throttle valve position indication problems.The plant returned to full power operation following repairs and re-calibration of position indication.

Later, the plant reduced power to trouble shoot reactor feedwater pump speed control problems.Following repairs to speed control linkage and governor valve actuator system, the plant returned to full power operation.
