| Title | Unusual Event Declared Due to Toxic Gas Leak |
| Event Description | At 0900, the Brunswick Steam Electric Plant (BSEP) declared an Unusual Event due to a release of Freon from the 2A Turbine Building Chiller. The classification of the Unusual Event is based on Emergency Action Level (EAL) HU3.1, 'Toxic, corrosive, asphyxiant or flammable gases in amounts that have or could adversely affect normal plant operations.' Actions have been taken to secure the chiller and isolate the release of Freon; however, Freon continues to be released. The release is only affecting the area immediately surrounding the 2A Turbine Building Chiller. No other plant areas are being impacted.
There is no impact on the health and safety of the public. The licensee notified Brunswick Warning Point, Hanover Warning Point, State Warning Point and the NRC Resident Inspector. Notified DHS, FEMA, DHS NICC and NuclearSSA (email).
At 1545 EST on 2/26/13, Brunswick terminated their Unusual Event based on the fact that the entry conditions no longer existed. A temporary patch has been installed on the 2A Turbine Building Chiller and work is in progress to evacuate residual Freon from the chiller unit. The licensee notified state and local agencies and the NRC Resident Inspector. Notified R2DO (Musser), IRD (Kozal) and NRR (Chernoff). Notified DHS, FEMA, DHS NICC and NuclearSSA (email). |
