Transmittal of Safety Evaluation for EPRI Report 3002025288, Enhanced Risk-Informed Categorization Methodology for Pressure Boundary Components, for Proprietary Review (L-2023-NTR-0008)

Fernando Ferrante, Program Manager, Risk & Safety Electric Power Research Institute 1300 West W.T. Harris Boulevard Charlotte, NC 28262-8550

Dear Fernando Ferrante:

By letter dated August 17, 2023 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML23234A266), as supplemented on November 30 and June 14, 2023 (ADAMS Accession Nos. ML23334A210 and ML24180A016), and April 30, 2025 (ADAMS Accession No. ML25121A201) Electric Power Research Institute (EPRI) submitted EPRI Technical Report (TR) 3002025288, Enhanced Risk-Informed Categorization Methodology for Pressure Boundary Components, dated June 2023, to the U.S. Nuclear Regulatory Commission (NRC) for review and approval. By e-mail dated July 11, 2024 (ADAMS Accession No. ML23352A054), the NRC staff accepted EPRI TR 3002025288 for review.

Based on its review of the information submitted in the TR, the NRC staff finds the TR is acceptable for referencing subject to the limitations specified in the TR, and in the NRC safety evaluation (SE).

The NRC staff evaluation is provided in the draft SE.

A copy of the SE for proprietary has been placed in the NRC external sharing folder for EPRI topical reports. Ashley Lindeman and you have been given access to the folder. Currently, the SE is being provided for a proprietary information review. If EPRI provides comments on other areas, the NRC staff will exercise its discretion on whether to address those comments.

Pursuant to Section 2.390 of Title 10 of the Code of Federal Regulations (10 CFR), we do not believe that the SE contains proprietary information. If you believe that any information in the SE is proprietary, please identify such information line-by-line and define the basis pursuant to the criteria of 10 CFR 2.390. Use double brackets and yellow highlight to identify any (( proprietary information )). Your response is due back to the NRC no later than 30 days from the date of this email and be via a letter from an authorized individual.
