NRC introduces microreactor regulatory framework
The Nuclear Regulatory Commission has released a new licensing framework for microreactors and similar reactor designs that may provide a more suitable pathway for applicants with simpler technologies.
The proposed rule—known as Part 57—is the latest to come out of the NRC’s rules review and overhaul stemming from the ADVANCE Act and 2025 nuclear-related executive orders. It is also the latest framework developed for advanced reactor designs shifting away from light water reactor technology, such as the Part 53 rule finalized in March.

Take part in a workshop convening space nuclear leaders to shape the success of commercial space radioisotope power systems (RPS) by taking the first step toward developing industry-led consensus standards for testing and qualification of radioisotope heat sources.
Engage in discussions about current standards, gaps, and the crucial role of industry in creating a successful safety standards framework. During this three-hour session, we will collaborate on a roadmap for an industry-developed standard to drive innovation, ensure safety, and pave the way for qualifying new radioisotope heat and power source designs for space missions.
The workshop will be facilitated by the Pacific Northwest National Laboratory (PNNL). Drawing on diverse technical, regulatory, and policy expertise and capabilities from across the laboratory, PNNL leads creative and multidisciplinary teams that are developing solutions for complex, rapidly evolving space challenges. Founded in 1965, PNNL is managed and operated by the Battelle Memorial Institute for the U.S. Department of Energy’s Office of Science.
