Title | Offsite Notification for Spill in the River Bend Owner Control Area |
Event Description | On January 8, 2014, at 1439 CST, River Bend Station management determined that a spill discovered on the morning of January 7 was reportable in accordance with NEI 07-07 (Nuclear Energy Institute), Ground Water Protection Initiative. The spill was the result of freeze damage that occurred on a valve connected to the cooling tower blow-down line. Dams were installed to prevent the water from reaching any storm drains, and the spill was confined to the owner-controlled area. Since this system has the potential to contain diluted radioactive plant effluent, samples were collected for analysis. The leak was immediately reduced to a small drip and actions are in progress to completely isolate and repair the valve. The effluent was determined today to contain 4584 pico-curies per liter of tritium, but no detectable gamma activity. The calculated volume of the leak was between 100 and 1200 gallons. This exceeds the NEI reporting criterion of 100 gallons from a source containing licensed material. The Louisiana Department of Environmental Quality was notified at 1549 CST today.
This event is being reported in accordance with 10 CFR 50.72(b)(2)(xi) as an event requiring notification of the state government. The NRC resident inspector has been notified. |
