| Title | Emergency Declared Due to Indicated Fire in Emergency Response Facility Substation |
| Event Description | At 2139, the licensee declared a Notification of Unusual Event in response to a fire alarm and CO2 activation in the emergency response facility (ERF) substation. The licensee entered emergency action level (EAL) 4.1. The fire brigade responded to assess for damage. No damage was found. The incident was attributed to a spurious activation of the CO2 system. The licensee terminated the unusual event at 2236.
The licensee notified the NRC Resident Inspector. The NRC did not change agency response mode for this event.
The CO2 discharge was isolated to the Emergency Response Facility Substation Building, and the building has been ventilated. Investigation into the cause of the spurious CO2 actuation is ongoing. Notified the R1DO (Burritt) via email. |
