II. The Petitioner and Petition The petition for rulemaking (PRM) was filed by Ralph O. Meyer. The PRM requests that the NRC revise its regulations at part 50 of title 10 of the Code of Federal Regulations (10 CFR), ‘‘Domestic Licensing of Production and Utilization Facilities,’’ regarding the licensing safety analysis for loss-ofcoolant accidents (LOCAs). The PRM requests that the NRC amend its regulations at 10 CFR 50.46, ‘‘Acceptance criteria for emergency core cooling systems for light-water nuclear power reactors,’’ which limits peak cladding temperature and maximum cladding oxidation to satisfy General Design Criterion No. 35 of appendix A to part 50, ‘‘Emergency core cooling.’’ The petition may be found in ADAMS at Accession No. ML22284A087. III. Discussion of the Petition The letter from the petitioner states that the NRC’s current rule ‘‘limits peak cladding temperature and maximum cladding oxidation’’ and ‘‘no longer ensures coolable geometry at higher fuel burnups’’ and includes an analysis and discussion of a proposed alternative. The petitioner requests the NRC to conduct rulemaking to implement criteria in 10 CFR 50.46 that would limit the number of fuel rod ruptures to 10 percent for large break LOCAs and to 1 percent for small break LOCAs, in lieu E:\FR\FM\23NOP1.SGM 23NOP1 71532 Federal Register / Vol. 87, No. 225 / Wednesday, November 23, 2022 / Proposed Rules of existing acceptance criteria in 10 CFR 50.46(b). The petitioner argues that current licensing safety analyses for LOCAs are no longer valid for fuel at moderate and higher burnups. According to the petitioner, the German regulatory agency uses these criteria. IV. Conclusion The NRC has determined that the petition meets the sufficiency requirements for docketing a PRM under 10 CFR 2.803, ‘‘Petition for rulemakingNRC action.’’ The NRC will examine the issues raised in PRM–50–124 and any comments received in response to this comment request to determine whether these issues should be considered in rulemaking.

II. The Petitioner and Petition

    The petition for rulemaking (PRM) was filed by Ralph O. Meyer. The 
PRM requests that the NRC revise its regulations at part 50 of title 10 
of the Code of Federal Regulations (10 CFR), ``Domestic Licensing of 
Production and Utilization Facilities,'' regarding the licensing safety

the NRC amend its regulations at 10 CFR 50.46, ``Acceptance criteria

requirements for docketing a PRM under 10 CFR 2.803, ``Petition for
