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 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 acceptable 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 staff has determined that a regulatory audit of the EPRI TR 3002028673 should be conducted in accordance with the Office of Nuclear Regulatory Reactor Office Instruction (OI) LIC-111, Regulatory Audits, Revision 2, dated December 2024 (ADAMS Accession No. ML24309A281), for the staff to gain a better understanding of EPRIs proposed ALS for LOCA Analysis for FFRD with LBB Credit. Regulatory review activities for EPRI Reports 3002028675 (NP)/3002028674 (P) and 3002023895 are being handled as separate activities.
The NRC staff plans to conduct the audit to better understand the application 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 and NRC-established MS Teams Meeting. However, should the staff determine that an in-person audit would be a more
