The exact cause of the vibration increase has not been determined; however, a potential cause could have been closure of the Reheat Steam Source Valves for the Moisture Separator Reheaters. Testing and inspection revealed no actual failure which would have caused the valves to close. Addtionally, personnel were interviewed to determine if the switch had been repositioned. The results were negative. 90-011 901019 S 0 B 5 N/A HF PUMPXX Load was reduced to allow (B) repair of the oil slinger ring on the "A" Circulating-Water Pump.
