November 6, 2023 MEMORANDUM TO:
Scott W. Moore, Executive Director Advisory Committee on Reactor Safeguards FROM:
Brian W. Smith, Director /RA/
Division of New and Renewed Licenses Office of Nuclear Reactor Regulation
SUBJECT:
NUSCALE POWER, LLC, SAFETY EVALUATION REPORT FOR LICENSING TOPICAL REPORT: TR-108601-P, REVISION 4, STATISTICAL SUBCHANNEL ANALYSIS METHODOLOGY, SUPPLEMENT 1 TO TR-0915-17564-P-A, REVISION 2, SUBCHANNEL ANALYSIS METHODOLOGY By letter dated December 30, 2021 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML21364A133), NuScale Power, LLC (NuScale), submitted licensing Topical Report (TR)-108601-P, Revision 0, Statistical Subchannel Analysis Methodology, Supplement 1 to TR-0915-17564-P-A, Revision 2. By letter dated November 6, 2023 (ML23310A122 ), NuScale submitted Revision 4 of TR-108601-P (hereafter referred to as the TR). NuScale requested U.S. Nuclear Regulatory Commission (NRC) approval of the subchannel methodology for calculating margin to fuel thermal limits.
Based on its review of NuScales TR, the NRC staff prepared a safety evaluation (SE)
(ML23269A087, Proprietary and ML23277A007, Nonproprietary). This SE is being provided to support a meeting of the subcommittee of the Advisory Committee on Reactor Safeguards (ACRS) on January 23, 2024.
The NRC staff concludes that the non-proprietary version of the SE does not contain any information exempt from public disclosure. However, the NRC will withhold the nonproprietary SE from public disclosure for ten business days to allow NuScale the opportunity to verify the staffs conclusion that the SE contains no such exempt information. Therefore, the NRC staff requests that the ACRS withhold the nonproprietary version of SE from public disclosure until the information has been released publicly in ADAMS.
