A circuit card ,

had shorted out due to condensation dripping onto the card from a conduit above. Replaced circuit card and sealed the above conduit. Further details in CR-98-0947.

98-03 980722 F 0.0 A 5 A power reduction was required to take Main Feedwater Pump A offline due to oscillation problems in the pump speed. High moisture content in the turbine lube oil is blamed for the erratic speed fluctuation. The turbine lube oil and filters were changed out and the pump speed is being controlled via the j HP governor valve. Further details in CR-98-0984. l 1
