Title | Offsite Notification for Condensate Spill in the Turbine Building |
Event Description | On August 1, 2015, during tagging activities to support planned maintenance on a condensate demineralizer, operators incorrectly positioned certain air-operated components which, combined with apparent leakage past a solenoid valve, resulted in a drain opening on a demineralizer that was in service. Flow through the drain line caused a turbine building sump to overflow to the floor of the 67 foot elevation of the Turbine Building. Immediate actions were taken to stop the leak.
The spill volume was approximately 60,000 gallons of condensate. The tritium activity of the water is estimated at 1.32E-2 microCi/ml. Gamma activity was from noble gases only in a concentration of approximately 2.30E-6 microCi/ml. The spill was confined to the Turbine Building. The affected area contains degraded floor seals which might allow the spill to reach groundwater. The reason for this notification is that industry and governmental officials were notified of this event on August 3, 2015. The NRC Senior Resident Inspector was notified and informal notification was made to the NRC Region IV office, the Louisiana Department of Environmental Quality, and West Feliciana Parish government authorities. The Nuclear Energy Institute was informed as specified in their ground water protection initiative. Plant cleanup activities arising from the spill are complete. |
