Event Reports: Three nuclear facilities fail recent tests

Some items from this morning’s NRC Event Reports page:

1. Global Nuclear Fuels notified the NRC that one of the alarm sirens, part of its onsite Critical Accident Alerm System at its nuclear fuel fabrication facility in Wilmington, North Carolina, was found to be inoperable during routine testing Thursday morning. Personnel were evacuated from the affected building until the siren is repaired.

2. Thursday afternoon, the High Pressure Coolant Injection (HPCI) for Unit 1 at the Browns Ferry nuclear power plant in Alabama failed during surveillance testing. The HPCI failure was determined to be reportable as an “event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.”

3. Early Thursday evening, operators performing testing at the McGuire nuclear power plant in North Carolina discovered a condition in the Unit 2 Steam Generator Power Operated Relief Valves that “could adversely affect the ability to achieve and maintain a cold shutdown of Unit 2.” An indentical situation was indentified at McGuire’s Unit 1 reactor in late March. Both units continue to operate at 100 per cent power.
