The Nuclear Regulatory Commission unveiled a final rule Wednesday that for the first time creates a distinct regulatory pathway for advanced nuclear reactors.
The “Part 53” rule would be the first regulation to address licensing of U.S. reactors in more than three decades. Existing NRC rules were designed to cover larger, “light-water” reactors, but not many of the new models being eyed by industry and the Trump administration.
The final rule “is another example of how the NRC is delivering on its mission by keeping safety at the forefront while aligning to the evolving nuclear energy landscape,” said NRC Chair Ho Nieh in a statement.
The plan aims to slash the time for approval of projects through various means, including by reducing unnecessary duplication in reviews and allowing developers to complete licensing in stages. It creates a new category of licensing for advanced reactors.
