3150-AK79 202304 Unified Agenda of Federal Regulatory and Deregulatory Actions 3150 Nuclear Regulatory Commission NRC Increased Enrichment of Conventional and Accident Tolerant Fuel Designs for Light-Water Reactors [NRC-2020-0034]

This rulemaking would amend the NRC’s regulations associated with uranium-235 enrichment limit. The rulemaking would increase flexibility and reduce exemption requests for the use of increased enrichment fuel greater than the current value of 5.0 weight percent U-235. This rulemaking would affect nuclear reactor licensees seeking to use fuel designs that make use of enrichments greater than the current limit (e.g., accident tolerant fuel).
