Risk-Informed, Technology-Inclusive Regulatory Framework for Advanced Reactors

Monday, March 30, 2026

Plain English Summary

The U.S. Nuclear Regulatory Commission (NRC) has updated its rules to create a new framework for regulating commercial nuclear plants. This change affects all future nuclear plants, especially those using advanced technologies that are different from traditional light-water reactors. The new rules are designed to be more flexible and take into account the specific risks and performance of these newer reactor designs. Insurance agents should be aware of these changes as they may impact coverage and liability for nuclear facilities moving forward.

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.
