Title | Unusual Event Declared Due A Fire Alarm In The Containment Building |
Event Description | An Unusual Event (NOUE) was declared at 0013 EST on 3/2/2014 due to a possible fire in the protected area inside containment which could not be verified within 15 minutes (EAL HU4). A containment building smoke alarm was received at 2120 on 3/1/14 after indications that a relief valve lifted during a safety injection accumulator fill evolution. Diverse containment instrumentation was checked and showed that containment dew point was elevated while containment temperature and pressure remained steady. The fire alarm was reset and did not reflash. A containment entry will be made to investigate the alarm. There are no requests for the local fire department to respond and there are no indications of a radiological release to the environment.
The NRC Resident Inspector has been notified. The licensee notified the Commonwealth of Pennsylvania Emergency Management Agency, Beaver County in Pennsylvania, the State of Ohio, Columbiana County in Ohio, the State of West Virginia and Hancock County in West Virginia. Notified DHS SWO, FEMA, NICC and Nuclear SSA (via email).
The licensee terminated the NOUE at 0205 EST after a containment entry determined no fire or indications of fire existed. Notified R1DO (DeFrancisco) IRD (Grant), NRR EO (Nieh), DHS SWO, FEMA, DHS NICC, and Nuclear SSA (via email). |
