Increased Enrichment of Conventional and Accident Tolerant Fuel 
Designs for Light-Water Reactors; Extension of Comment Period

AGENCY: Nuclear Regulatory Commission.

ACTION: Regulatory basis; extension of comment period.

-----------------------------------------------------------------------

SUMMARY: On September 8, 2023, the U.S. Nuclear Regulatory Commission 
(NRC) requested comments on the regulatory basis to support a 
rulemaking to amend the NRC's regulations related to the use of 
conventional and accident tolerant light-water reactor fuel designs. 
The public comment period was originally scheduled to close on November 
22, 2023. The NRC has decided to extend the public comment period to 
allow more time for members of the public to develop and submit their 
comments.

DATES: The due date of comments requested in the document published on 
September 8, 2023 (88 FR 61986) is extended. Comments should be filed 
no later than January 22, 2024. Comments received after this date will 
be considered, if it is practical to do so, but the NRC is able to 
ensure consideration only for comments received on or before this date.

ADDRESSES: You may submit comments by any of the following methods; 
however, the NRC encourages electronic comment submission through the 
Federal rulemaking website:
     Federal Rulemaking Website: Go to https://www.regulations.gov and search for Docket ID NRC-2020-0034. Address 
questions about NRC dockets to Dawn Forder; telephone: 301-415-3407;

Light-Water Reactors, is available in ADAMS under Accession No. 
ML23032A504.
     NRC's PDR: The PDR, where you may examine and order copies 
of publicly available documents, is open by appointment. To make an

state that the NRC does not routinely edit comment submissions to 
remove such information before making the comment submissions available 
to the public or entering the comment into ADAMS.

II. Discussion

    On September 8, 2023, the NRC requested comments on a regulatory 
basis titled ``Increased Enrichment of Conventional and Accident 
Tolerant Fuel Designs for Light-Water Reactors'' to support a 
rulemaking that would amend the NRC's regulations to facilitate the use 
of light-water reactor fuel containing uranium enriched to greater than 
5.0 weight percent uranium-235 (U-235) in part 50 of title 10 of the 
Code of Federal Regulations (10 CFR), ``Domestic Licensing of 
Production and Utilization Facilities,'' 10 CFR part 51, 
``Environmental Protection Regulations for Domestic Licensing and 
Related Regulatory Functions,'' and 10 CFR part 71, ``Packaging and 
Transportation of Radioactive Material.'' This rulemaking would allow 
the NRC to prepare for the effective and efficient licensing of 
applications using fuels enriched to greater than 5.0 and less than 
20.0 weight percent U-235 without compromising reasonable assurance of 
adequate protection of public health and safety, reduce the need for 
exemptions from existing regulations and license amendment requests, 
provide licensees operational flexibility and certainty in licensing of 
accident tolerant fuel, and support the principles of good regulation. 
The rule changes would apply to any light-water power reactor 
application submitted to the NRC under 10 CFR part 50 and part 52, 
``Licenses, Certifications, and Approvals for Nuclear Power Plants.''
    The public comment period was originally scheduled to close on 
November 22, 2023. The NRC has decided to extend the public comment 
period on this document until January 22, 2024, to allow more time for 
members of the public to submit their comments.
    The NRC may post materials related to this document, including 
public comments, on the Federal rulemaking website at https://www.regulations.gov under Docket ID NRC-2020-0034. In addition, the 
Federal rulemaking website allows members of the public to receive
