PRESSURE BOUNDARY LEAKAGE DISCOVERED DURING HYDRO TEST
The following information was obtained from the licensee via fax (licensee text in quotes):
"At 22:30 on 3/20/2005, the Control Room was notified by the test director that ASME CLASS I Boundary System Leakage Hydrostatic Pressure Test (SE-200-002) had failed. The reason was a leak identified on Reactor Recirc Pump B Discharge Valve, HV243F031B. The leak is coming from the Stub Tube Weld Leakoff Connection for the valve. It is leaking approx. 10 drops per minute. Technical Requirement 3.4.2 was entered. It was determined to be unacceptable under the ASME Section XI Code. Based on guidance provided in NUREG-1022, Rev. 2, this material defect in the primary coolant boundary constitutes a seriously degraded condition and is reportable under 10CFR50.72(b)(3)(ii)(A). A final evaluation of the flaw and a repair plan is being developed."
The NRC Resident was notified.
