Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors

The Nuclear Regulatory Commission is proposing to amend its regulations to provide a performance-based option for leakage rate testing of containments of light-water-cooled nuclear power plants. This option will be available for voluntary adoption by licensees, in lieu of compliance with the current prescriptive requirements contained in the current regulation. This action is aimed at improving the focus of the regulations by eliminating prescriptive requirements that are marginal to safety. The proposed rule would allow test intervals to be based on system and component performance, and provide licensees greater flexibility for cost-effective implementation methods of regulatory safety objectives.
