Regulatory Roulette: The NRC’s Inconsistent Oversight of Radioactive Releases from Nuclear Power Plants

The Union of Concerned Scientists reports that the NRC has inconsistently enforced safety regulations for radioactive releases, allowing numerous accidental leaks to occur without sanction. While the NRC previously issued sanctions for monitoring and control failures, the report claims the agency has tolerated 27 accidental releases over a four-year period with impunity, effectively breaching its safety contract with the public.

• The NRC has failed to consistently apply its regulatory requirements—monitoring, controlling, and capping radioactive releases—resulting in more than 400 accidental leaks, some of which involved millions of gallons of contaminated water and remained undetected for years.
• The NRC has shifted from sporadically sanctioning plant owners to a period of total non-enforcement; specifically, the agency imposed no sanctions for 27 accidental releases occurring between 2006 and 2010.
• Accidental radioactive leaks have caused tangible financial harm to the public, such as at the Braidwood plant in Illinois, where over six million gallons of tritium-laden water leaked, leading to depressed home prices for nearby residents.
• The NRC's enforcement is described as inconsistent and arbitrary, as evidenced by the agency preventing the River Bend plant from restarting in 2008 due to a potential (but not actual) leak pathway, while allowing the Vermont Yankee plant to continue operating in 2010 despite an active, unmonitored release of contaminated liquid.
• The nuclear industry was actively involved in crafting the General Design Criteria (GDC) that govern radioactive releases, meaning the industry cannot claim these regulations are too vague or onerous to follow.
• The NRC often dismisses leaks by citing Environmental Protection Agency (EPA) drinking water standards, but the report argues that meeting EPA limits does not excuse the violation of NRC's more stringent monitoring and control standards.
