What the agency says
The U.S. Nuclear Regulatory Commission (NRC) is amending its regulations by adding a risk-informed, performance-based, and technology-inclusive regulatory framework for commercial nuclear plants in response to the Nuclear Energy Innovation and Modernization Act (NEIMA). The current application and licensing requirements were primarily developed to address license requests concerning light water- cooled reactors and operational requirements for those types of reactors. This final rule responds to NEIMA by creating an alternative, technology-inclusive regulatory framework to accommodate licensing of future commercial nuclear plants, including advanced reactor designs that may not employ light-water technology.
