MR Number: 3-95-0135 Quad Cities 2 Date: 08/14/95 Cordova,Illinois AUGUST 13, 1995; RI VIA LAN Dockets: 50-265 BWR/GE-3 Subject: FORCED OUTAGE ON UNIT 2 DUE TO RELIEF VALVE "WEEPAGE" AND ELECTRO-HYDRAULIC CONTROL SYSTEM LEAKS. Reportable Event Number: N/A Discussion: Since plant startup from a refueling outage on July 24, four power operated relief valves (PORVs) have exhibited elevated downstream tail pipe temperatures. On August 12 the licensee cycled one PORV in an attempt to better seat the valve. The remaining three PORVs were cycled on August 13. One of the four PORVs reseated properly; however, seat leakage on the other three worsened. The four leaking PORVs were installed during the recent refueling outage. Additionally, on August 12 the licensee identified that about 2 inches of oil had been lost from the EHC system reservoir over a 6 hour period. A leak was found at a plug on a main turbine combined intercept valve's accumulator. That accumulator was also installed during the recent refueling outage. The turbine was taken off line on August 12 to repair the EHC leak. On August 13, operators performed a normal shutdown of Unit 2 to repair the PORV leakage. The licensee was evaluating the scope of the repairs to be performed during the forced outage. Regional Action: The resident inspectors continued to monitor licensee troubleshooting and repair activities. Contact: P.L.
