REGULATORY AUDIT
SUMMARY
FOR THE JANUARY 18, 2023, AUDIT FOR TOPICAL REPORT PWROG-21001-P/NP, REVISION 0, HYDROGEN-BASED TRANSIENT CLADDING STRAIN LIMIT (EPID L-2022-TOP-0043)
Dear Mr. Olinski:
By letter dated July 28, 2022 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML22209A254), Pressurized Water Reactor Owners Group (PWROG) submitted Topical Report (TR) PWROG-21001-P/NP, Revision 0, Hydrogen-Based Transient Cladding Strain Limit, for U.S. Nuclear Regulatory Commission (NRC) review and approval for referencing in regulatory actions per the NRC TR program. The purpose of this TR is to establish a new, alternative fuel performance design limit for transient cladding strain. The TR will facilitate PWROG licensees use of a data-driven, performance-based design limit when performing transient cladding strain analyses. This is an alternative limit which, after NRC approval, can be used in lieu of the current one percent transient cladding strain limit established in Section 4.2, Fuel System Design, of NUREG-0800, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition.
This TR is applicable to Westinghouse Electric Company nuclear steam supply system (NSSS) and Combustion Engineering NSSS PWROG members that use Westinghouse Performance Analysis and Design Model (PAD5) fuel performance models for ZIRLO and/or Optimized ZIRLO' high performance fuel cladding material.
The NRC staff conducted a virtual regulatory audit on January 18, 2023, to increase review efficiency (ADAMS Accession No. ML22361A156). The audit was held in accordance with the Office of Nuclear Reactor Regulation (NRR) Office Instruction LIC 111, Regulatory Audits, dated October 31, 2019 (ADAMS Accession No. ML19226A274).
The regulatory audit summary is enclosed with this letter.
NOTICE: Enclosure 1 to this letter contains proprietary information. When separated from, this document is DECONTROLLED.
