Tritium is a mildly radioactive type of hydrogen that occurs both naturally and during the operation of nuclear power plants. Water containing tritium and other radioactive substances is normally released from nuclear plants under controlled, monitored conditions the NRC manda...
A radioactive isotope of hydrogen. Because it is chemically identical to natural hydrogen, tritium can easily be taken into the body by any ingestion path. It decays by emitting beta particles and has a half-life of about 12.5 years. For related information, see the Fact Shee...
The NRC was notified on Feb. 5, 2016, by Entergy of a new on-site tritium leak at the Indian Point nuclear power plant. Entergy, which owns and operates the Buchanan, N.Y., facility became aware of the leakage via samples drawn from existing groundwater monitoring wells. One o...
Water containing trace amounts of various radioactive materials is normally released from U.S. nuclear power plants under controlled, monitored conditions that meet conservative NRC limits to protect public health and safety. Recently, several instances of unintended, abnormal...
§ 63.331 Separate standards for protection of groundwater.DOE must demonstrate that there is a reasonable expectation that, for 10,000 years of undisturbed performance after disposal, releases of radionuclides from waste in the Yucca Mountain disposal system into the accessibl...
The Nuclear Regulatory Commission has been overseeing nuclear power plants and their tritium monitoring programs for several years. Our reviews have confirmed leaks with tritium in underground pipes have not affected public health and safety and the environment. More informati...
