| Title | Brunswick Declared Alert Due to Halon Discharge in Emergency Diesel Generator Building |
| Event Description | At 1137 EDT, Brunswick Units 1 & 2 declared an Alert condition due to a discharge of Halon gas into the basement of the emergency diesel generator building (EAL H.A.3.1 for toxic gas discharge into a vital area). Initial inspection indicates that there is no fire. No offsite assistance was required and no personnel injuries as a result of the discharge. Both reactors continue to operate at 100% power. The licensee is investigating the cause of the discharge and will terminate the Alert when the area is ventilated and can be reoccupied.
The licensee has notified State and local authorities and the NRC Resident Inspector.
The licensee terminated the Alert at 1614 EDT based on restoring normal atmosphere conditions in the emergency diesel generator building. The initiating cause of this event is still being investigated. State and local authorities have been notified and the Resident Inspector will be notified. The NRC Operations Center has notified the Federal Agencies initially notified of this event. R2DO (Vias), NRR EO (Galloway) and IRD (Grant) notified. |
