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 sta accepted EPRI TR 3002025288 for review.

By e-mail dated June 27, 2025 (ADAMS Accession No. ML25191A213), EPRI informed the NRC sta that there was no proprietary information in the SE for proprietary review.

The NRC sta has found that EPRI Report 3002025288, Enhanced Risk-Informed Categorization Methodology for Pressure Boundary Components is acceptable for referencing in licensing applications for nuclear power plants to the extent speci"ed and under the limitations delineated in the TR and in the enclosed "nal SE. The "nal SE de"nes the basis for our acceptance of the TR.

Our acceptance applies only to material provided in the subject TR. We do not intend to repeat our review of the acceptable material described in the TR.
