WESTINGHOUSE ELECTRIC COMPANY, LLC. - FINAL SAFETY EVALUATION FOR REVISION 0 OF THE EVR-LIC-RL-003-P/NP, TRISO FUEL DESIGN METHODOLOGY TOPICAL REPORT (EPID: L-2024-TOP-0028)
Dear Mr. Schoedel:
By letter dated July 31, 2024 (Agencywide Documents Access and Management System, Accession Number, ML24214A277), Westinghouse Electric Company, LLC. (Westinghouse) submitted for the U.S. Nuclear Regulatory Commission (NRC) staffs review, Revision 0 of the EVR-LIC-RL-003-P/NP, TRISO Fuel Design Methodology Topical Report.
The NRC staff's final safety evaluation (SE) for the topical report (TR) is enclosed. Enclosure 1 is the redacted version of the SE and will be made publicly available. Enclosure 2 contains proprietary information and access to this document will be controlled, consistent with the regulations in Title 10 of the Code of Federal Regulations, Section 2.390, Public inspections, exemptions, requests for withholding.
The NRC staff has determined that Westinghouse provides an acceptable approach for TRISO fuel qualification, subject to the limitations and conditions discussed in the SE, by outlining a methodology that follows NUREG-2246, Fuel Qualification for Advanced Reactors, and Regulatory Guide 1.203, Transient and Accident Analysis Methods. Successful implementation of this methodology will rely on benchmarking and data validation; the completion of both are conditions that must be met for the TR to be referenced in future submittals. Accordingly, the NRC staff concludes that Westinghouses TR can be used to support reactor licensing applications for permits, licenses, certifications, or approvals under 10 CFR Part 50, Domestic Licensing of Production and Utilization Facilities, or 10 CFR Part 52, Licenses, Certifications, and Approvals for Nuclear Power Plants. to this letter contains proprietary information. When separated from the Enclosure 2, this letter is DECONTROLLED.
