Final Request for Additional Information for EPRI Report 3002028675 (NP)/3002028674 (P), LOCA Analysis of Fuel Fragmentation, Relocation, and Dispersal [FFRD] for Westinghouse 2-Loop, 3-Loop and 4-Loop Plants - Proprietary, Evaluation of Cladding Rupture Dr. Aylin Kucuk Program Manager, Nuclear Fuels Electric Power Research Institute Palo Alto Oice 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 (1) EPRI Report 3002028673, Loss-of-Coolant-Accident-Induced Fuel Fragmentation, Relocation, and Dispersal with Leak-Before-Break Credit -
Alternative Licensing Strategy [ALS], (2) EPRI Report 3002028675 (NP)/3002028674 (P), LOCA [Loss of Coolant Accident] Analysis of Fuel Fragmentation, Relocation, and Dispersal [FFRD] for Westinghouse 2-Loop, 3-Loop and 4-Loop Plants - Proprietary, Evaluation of Cladding Rupture in High Burnup Fuel Rods Susceptible to Fine Fragmentation (collectively called ALS for LOCA Analysis of FFRD), and (3) EPRI Report 3002023895, Materials Reliability Program: xLPR [Extremely Low Probability of Rupture] Estimation of PWR Loss-of-Coolant Accident Frequencies (MRP-480) to the U.S. Nuclear Regulatory Commission (NRC) for review and approval. The ALS for LOCA Analysis for FFRD topical report demonstrates an alternative performance for LOCA induced FFRD phenomena in high burnup pressurized water reactor (PWR) fuel.
By email dated June 25, 2024 (ADAMS Accession No. ML24170A812), the NRC accepted the EPRI topical reports (TRs) for review and approval. The NRC acceptance package includes completion forms and schedules for three TRs, and the withholding determination for the proprietary TR.
The NRC sta the Nuclear Methods and Fuel Analysis Branch (SFNB) in the Division of Safety Systems (DSS) is in the process of reviewing your application. Based on our review, the NRC sta has identi"ed the attached draft requests for additional information (RAIs).
