Licensing Requirements for Microreactors and Other Reactors With Comparable Risk Profiles

Document 2026-08550 is a Proposed Rule published by the Nuclear Regulatory Commission in the Federal Register on May 1, 2026. The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its regulations to establish a risk-informed and performance- based regulatory framework for rapid licensing of new microreactors and other reactors with comparable risk profiles and for high-volume deployment of these reactors. The proposed rule would provide a flexible set of licensing pathways, reduce regulatory burden, and ensure that safety and security requirements remain commensurate with the potential hazards posed by these facilities.
