SUBJECT:
REVISION OF DATES FOR REVIEW OF ELECTRIC POWER RESEARCH ALTERNATIVE LICENSING STRATEGY TOPICAL REPORTS (EPID NOS. L-2024-NTR-0002, L-2024-NTR-0003, L-2024-NTR-0004)
Dear Aylin Kucuk:
By letter dated June 25, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24170A813), the U.S. Nuclear Regulatory Commission (NRC) communicated that the following reports submitted by Electric Power Research Institute (EPRI) contain sufficient material to begin review.
(1) EPRI Report 3002028673, Loss-of-Coolant-Accident (LOCA)-Induced Fuel Fragmentation, Relocation and Dispersal (FFRD) with Leak-Before-Break (LBB)
Credit - Alternative Licensing Strategy (ALS)
(2) EPRI Report 3002028675 (NP)/3002028674 (P), LOCA Analysis of Fuel Fragmentation, Relocation, and Dispersal for Westinghouse 2-Loop, 3-Loop and 4-Loop Plants - Proprietary, Evaluation of Cladding Rupture in High Burnup Fuel Rods Susceptible to Fine Fragmentation (3) EPRI Report 3002023895, Materials Reliability Program: xLPR Estimation of PWR
[Pressurized Water Reactor] Loss-of-Coolant Accident Frequencies (MRP-480)
The purpose of this letter is to inform EPRI that the NRC has approved a revision to the original schedule to better manage resources and improve efficiency which can be found on the following table. Note that although intermediate milestones have shifted, neither the completion date of the package nor the anticipated review hours have changed.
EPRI Report MRP-480 Report 3002028674/5 Report 3002028673 Audit Dates March/April 2025 January/February 2025 May/June 2025 Request for Additional Information Issuance May 23, 2025 July 18, 2025 July 21, 2025 Draft SE Issuance December 4, 2025 February 6, 2025 February 17, 2026 Review Hours 1500 1500 1500

Code L-2024-TOP-0016 L-2024-TOP-0015 L-2024-TOP-0018 New EPID Code L-2024-NTR-0004 L-2024-NTR-0003 L-2024-NTR-0002 By letter dated April 26, 2024, EPRI submitted a fee exemption request to the NRC Chief Financial Officer (ADAMS Accession No. ML24121A209). By letter dated August 1, 2024, NRC granted the fee exemption request (ADAMS Accession No. ML24170A671). The table above reflects a change to new EPID codes based on the granting of the fee exemption.
