Title | Offsite Notification Due to Water Sample Testing Positive for Low Level of Tritium |
Event Description | On December 20, 2011, Vermont Yankee (VY) was notified by its vendor laboratory that a water sample, taken from the Connecticut River on November 3, 2011, tested positive for a low level of tritium [1120 pCi/L]. This report is being made in accordance with 10 CFR50.72(b)(2)(xi) since VY is notifying government agencies and issuing a press release. The VY Off-Site Dose Calculation Manual contains effluent dose calculations that account for groundwater releases of this type. There is no impact on public health and safety as a result of this event.
The licensee has notified the NRC Resident Inspector and the state of Vermont. |
