Dear Michael Ruszkowski:

By letter dated July 23, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24205A146), Electric Power Research Institute (EPRI) submitted EPRI Technical Report 3002028939, Risk-Informed High-Energy Line Break Evaluation Requirements, to the U.S. Nuclear Regulatory Commission (NRC) for review and approval. EPRI Report 3002028939 provides an alternative means for assessing and confirming that plant structures, systems, and components that are important to safety are adequate to accommodate the effects of postulated accidents, including appropriate protection against the dynamic and environmental effects of postulated pipe ruptures.

By letter dated July 11, 2024 (ADAMS Accession No. ML23352A054), the NRC staff accepted EPRI TR 3002025288 for review.

The NRC staff has reviewed the EPRIs topical report and determined that a regulatory audit would assist in the timely completion of the NRC staffs review. The NRC staff will conduct a regulatory audit to support its review of EPRI Report 3002028939 in accordance with the enclosed audit plan. The audit will increase the NRC staffs understanding of the topical report and identify information that will require docketing to support the NRC staffs regulatory findings.

The NRC staff plans to conduct the audit virtually at NRC Headquarters in Rockville, Maryland via a vendor-established electronic portal. However, should the staff determine that an in-person audit would be a more efficient method to conduct the audit and gather needed information, the staff may use that approach in addition to the virtual audit.

If you have any questions, please contact me by email at lois.james@nrc.gov.

Sincerely, Lois M. James, Senior Project Manager Licensing Projects Branch
