The NRC has made publicly available a pre-publication version of the proposed rule for Part 57, “Licensing Requirements for Microreactors and Other Reactors with Comparable Risk Profiles.” This early availability offers stakeholders additional time to review the rule before publication in the Federal Register and facilitates an improved opportunity for stakeholders to develop input during the public comment period.

The NRC issued a proposed rule for comment, which aims to streamline the reviews of reactor designs previously authorized by the Department of Energy or Department of War, as part of its EO 14300 rulemaking efforts. Comments can be submitted, referencing Docket ID NRC-2025-1503, at regulations.gov, through May 4, 2026.
