Change in Estimated Review Schedule and Level of Effort for Palisades Nuclear Plant Relief Request Number RR 5 RCS Piping Nozzle Dissimilar Metal Welds-L-2025-LLR-0079 Date:
Tuesday, December 2, 2025 12:46:00 PM Good afternoon Mike,
By letter dated August 20, 2025 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML25232A168), Holtec submitted a relief request for the Palisades Nuclear Plant. Specifically, Holtec is requesting an alternative to the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code), Case N-853-1, PWR Class 1 Primary Piping Alloy 600 Full Penetration Branch Connection Weld Metal Buildup for Material Susceptible to Primary Water Stress Corrosion Cracking,Section XI, Division 1, requirements. ASME Code Case N-853-1 has been incorporated by reference into 10 CFR 50.55a via inclusion in Regulatory Guide (RG) 1.147, Revision 21, Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1, without conditions. On September 19, 2025 (ML25280A005), the NRC staff notified you that your alternative request had been accepted for review and estimated a completion date by November 10, 2025, and 95 NRC staff hours to complete.
Due to ongoing work at the Palisades site related to this and several other relief requests, as well as unavailability of supplemental information until additional nondestructive examination (NDE) activities are completed at the site, the NRC staff was unable to meet the initially forecasted completion date of November 10, 2025. During recent routine interactions between myself and my Palisades Nuclear Plant licensing contact, Ms. Kami Miller, I informed her of the delay and reasons for the change in the schedule. The purpose of this email is to revise the schedule and staff hours estimate provided in the September 19, 2025, acceptance email.
The NRC staff now estimates that this licensing request may take up to 120 NRC staff hours to complete and expects to complete its review by January 30, 2026. This estimate is based on receiving supplemental information following completion of NDE activities, anticipated by December 19, 2025. These estimates could change due to several factors such as requests for additional information and an unanticipated addition of scope to the review. If there are emergent complexities or challenges in our review that would result in a change to the estimated completion date or significant changes in the estimated hours, the reasons for the change, and a revised estimate will be communicated during routine interactions with the assigned project manager.
The change in the estimated completion date and estimated hours was approved by the Deputy Director for the Division of Operating Reactor Licensing.
If you have any questions, please contact me.
