Groundwater Contamination (Tritium) at Nuclear Plants

The recent identification of the inadvertent release of water containing tritium at several reactors sites has caused the NRC to increase our oversight activities in this area. The NRC is reviewing these contamination incidents to determine what, if any, changes are needed to our regulatory program. Although the measured levels of tritium at the affected plants are above background levels, they remain well below NRC's regulations for release. Because there is a substantial amount of public interest, the NRC is providing information on the status of the unintended tritium leaks and the NRC's response.
