Acceptance Review for the Exemption Request From 10 CFR 50.55a(a)(3)(ii) for Code CaseN-921
Dear Ryan Treadway,
By letter dated May 8, 2025 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML25128A041), Duke Energy Carolinas, LLC, (the licensee, Duke Energy) submitted an exemption request for McGuire Nuclear Station (McGuire), Unit 1, H.B. Robinson Steam Electric Plant, Unit 2, and Oconee Nuclear Station, Units 1,2, and 3. The proposed exemption request is from the speci"c regulations of Title 10 of the Code of Federal Regulations (10 CFR) 50.55a(y) and 10 CFR 50.55a(a)(3)(ii), which incorporates by reference Code Case N-921 from Regulatory Guide 1.147, Revision 21. The exemption request, if granted, would allow for the implementation of American Society of Mechanical Engineers Code Case N-921during the current Inservice Inspection Interval.
2 The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) stas acceptance review of this exemption request. The acceptance review was performed to determine if there is suicient technical information in scope and depth to allow the NRC sta to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insuiciencies in its characterization of the regulatory requirements or the licensing basis of the plant.
The NRC sta has reviewed your application and concluded that it does provide technical information in suicient detail to enable the NRC sta to begin its detailed technical review and make an independent assessment regarding the acceptability of the proposed exemption in terms of regulatory requirements and the protection of public health and safety and the environment. Given the lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC stas ability to complete the detailed technical review are identi"ed despite completion of an adequate acceptance review. If additional information is needed, you will be advised by separate correspondence.
The NRC sta has evaluated precedence related to this request and determined that, on average, the reviews have required 132 hours0.00153 days <br />0.0367 hours <br />2.18254e-4 weeks <br />5.0226e-5 months <br /> and 6.7 months. To support a more eicient process, the NRC is setting a goal of achieving a 15% improvement. Based on that, our estimate for this review is 112 hours0.0013 days <br />0.0311 hours <br />1.851852e-4 weeks <br />4.2616e-5 months <br /> and 5.7 months. The NRC sta expects to complete the review by October 30, 2025.
If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date or signi"cant changes in the forecasted hours, the reasons for the changes along with the new estimates, will be communicated during the routine interactions with the assigned project manager.
These estimates are based on the NRC stas initial review of the application, and they can change due to several factors including requests for additional information, and unanticipated addition of scope to the review. Additional delay may occur if the submittal is provided to the NRC in advance or in parallel with industry program initiatives or pilot applications.
If you have any questions, please contact me.
Very Respectfully, Jack Minzer Bryant, Project Manager Nuclear Regulatory Commission Division of Operating Reactor Licensing NRR/DORL/LPL2-1 (301) 415-0610 Docket Nos.
