"The source of radioactive tritium in monitoring wells at Oconee Nuclear Station remains a mystery, and area residents are waiting for answers while workers are digging new test wells to narrow down the possibilities. ...
Leaking radioactive tritium is a problem at more than a quarter of the nation’s 104 nuclear facilities, said Pam Solo, founder and president of the Civil Society Institute, a Massachusetts-based non-profit and nonpartisan think tank.
Small amounts of tritium within allowable federal limits are released from every nuclear power plant as part of the normal process, said Roger Hannah, a Nuclear Regulatory Commission spokesman.
In addition, underground pipes have developed leaks at a number of plants, Hannah said. To this point, the leaks have been below regulatory limits and are deemed to be of 'low safety significance,' Hannah said."
