Abstract: FINAL RULE: Risk-Informed, Technology-Inclusive Regulatory Framework for Advanced Reactors The 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. The information collections associated with the final rule have been submitted under the following clearance numbers: 3150-0146 Burden for 10 CFR Part 26 (revision) 3150-0274 Burden for 10 CFR Part 53 (new clearance number for a new CFR Part) 3150-0272 NRC Forms 893 and 894 (new clearance number for a new form) 3150-0002: 10 CFR Part 73 (revision) 3150-0104: NRC Form 366 (revision) 3150-0271 Burden for 10 CFR Part 50 (temporary clearance number, 3150-0011 is currently unavailable for submissions due to the Alternatives to the Use of Credit Ratings final rule) 3150-XXXX: Burden for NRC Form 361 (temporary clearance number, 3150-0238 will soon be unavailable due to the upcoming renewal of this form) 3150-XXXX: Burden for NRC Form 396 (temporary clearance number, 3150-0027 is currently unavailable for submissions due to renewal) 3150-XXXX: Burden for NRC Form 398 (temporary clearance number, 3150-0090 is currently unavailable for submissions due to the renewal)
