| Title | Unusual Event Declared Due to a Toxic Gas Release Affecting Normal Operations |
| Event Description | At 1054 EST on 11/04/04, the licensee declared an Unusual Event due to an acidic water spray in the Water Treatment Building affecting normal access. Licensee entered EAL MU-1, Toxic Gas detected within the Protected Area that impacts normal operations. There were two personnel in the building at the time of the leak, one Non-licensed operator and his supervisor. The Non-licensed operator was overcome by fumes and became nauseous and was taken to the onsite dispensary. The non-licensed operator was treated and taken to the local hospital. The supervisor did not seem to be affected, but he has been taken to the onsite dispensary for any necessary treatment.
No unplanned release has occurred and no protective action recommendations are applicable at this time. The acidic water spray made contact with a 480 Vac panel in the building and has caused an electrical ground. Equipment in the building that may potentially affect plant operation if damaged are the clearwell pumps. The clearwell pumps supply seal water for the Main Circulating water pumps, and the non vital service water pumps. The licensee notified the NRC Resident Inspector and made all state and local government emergency management notifications.
Atmospheric conditions in the area have been confirmed to be normal. Slippery conditions and acid hazard still exist on the floor. Licensee is still in an Unusual Event. NRC Resident Inspector has been notified of this update. R3DO (S. Burgess) notified.
