Issuance of Safety Evaluation for EPRI Technical Report 3002028674/5, LOCA Analysis of Fuel Fragmentation, Relocation, and Dispersal for Westinghouse 2 Loop, 3-Loop, and 4-Loop Plants, for Proprietary Review (EPID L 2024 NTR 0003)

Dr. Aylin Kucuk Program Manager, Nuclear Fuels Electric Power Research Institute Palo Alto Office 3420 Hillview Ave.

Palo Alto, CA 94304-133

Dear Dr. Aylin Kucuk:

By letter dated April 26, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24121A203), Electric Power Research Institute (EPRI) submitted EPRI Report 3002028673, Loss-of-Coolant-Accident-Induced Fuel Fragmentation, Relocation, and Dispersal with Leak-Before-Break Credit -

Alternative Licensing Strategy [ALS], to the U.S. Nuclear Regulatory Commission (NRC) for review and approval.

The NRC staff has completed its review of the subject topical report and documented our review in the enclosed safety evaluation (SE).

Pursuant to Section 2.390 of Title 10 of the Code of Federal Regulations (10 CFR), we have determined that the SE for MRP-480 may contain proprietary information. If you believe that any information in the draft 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 ].

A copy of the SE for proprietary review has been placed in the NRC external sharing folder. Kurshad Muftuoglu has been given access to the folder. 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.

Please provide your response within 30 days of the date of this e-mail. Your response must be via a letter from an authorized individual. The final SE will be issued after making any necessary changes.

Note that at this stage of the process, the NRC staff has completed its review of the submitted information and will not entertain technical arguments. The NRC staff conclusions and conditions will not change unless new information is provided on the docket that was not available during our review. If EPRI would like to discuss the enclosed SE in detail, we can do that in a noticed meeting.

If you have any questions, please feel free to contact me at lois.james@nrc.gov.
