Change in Estimated Review Schedule and Level of Effort for Palisades Nuclear Plant Relief Request Number RR 5 RPV Vent Line Penetration Modifications - L-2025-LLR-0073 Date:
Tuesday, December 2, 2025 12:43:00 PM Good afternoon Mike,
By letter dated July 31, 2025 (Agencywide Documents Access and Management System (ADAMS) Accession No.ML25212A032), as supplemented on October 22, 2025 (ML25295A537), 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) requirements of a 100% surface examination coverage of the modified reactor vessel closure head vent line penetration weld due to hardship under Title 10 of the Code of Federal Regulations (10 CFR) 50.55a(z)(2). On September 12, 2025 (ML25258A098), 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 the timing of the supplemental information received on October 22, 2025, 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 12, 2025, acceptance email.
The NRC staff now estimates that this licensing request may take up to 150 NRC staff hours to complete and expects to complete its review by December 31, 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.
