Acceptance Review - Vogtle Units 3 and 4 - Use of 2019 Edition of ASME B&PV Code for ISI - EPID L-2025-LLR-0053
- Ken, By letter dated May 20, 2025 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML25140A970), Southern Nuclear Operating Company (SNC, the licensee) submitted a licensing request to the U.S. Nuclear Regulatory Commission (NRC) for use of a later code edition of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code,Section XI, requirements at Vogtle Electric Generating Plant (VEGP), Units 3 and 4. Pursuant to Section 50.55a(g)(4)(iv) of Title 10 of the Code of Federal Regulations (10 CFR), the licensee requested approval to use the 2019 Edition of the ASME B&PV Code,Section XI, in its entirety for inservice inspections (ISI) during the remainder of ISI interval 1 at VEGP, Units 3 and 4.
The purpose of this e-mail is to provide the results of the NRC stas acceptance review of this proposed licensing request. The acceptance review was performed to determine whether the application contains suicient technical information to allow the NRC sta to complete a detailed technical review. The acceptance review is also intended to identify any readily apparent de"ciencies related to the characterization of the regulatory requirements or plant licensing basis.
The NRC sta has reviewed your application and concluded that it includes technical information in suicient detail to enable the NRC sta to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed licensing request in terms of regulatory requirements and the protection of public health and safety and the environment. Given the more limited scope and depth of the acceptance review compared to the detailed technical review, issues that aect the NRC stas ability to complete the technical review may still be identi"ed despite the acceptance review being deemed adequate. If additional information is needed, you will be noti"ed by separate correspondence.
The NRC sta has evaluated precedence related to this request and determined that, on average, the reviews have required 46 hours5.324074e-4 days <br />0.0128 hours <br />7.60582e-5 weeks <br />1.7503e-5 months <br /> and 4.5 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 39 hours4.513889e-4 days <br />0.0108 hours <br />6.448413e-5 weeks <br />1.48395e-5 months <br /> and 4 months. The NRC sta expects to complete the review by September 11, 2025.
If emergent complexities or challenges arise during the NRC stas review that aect the initial forecasted completion date or result in signi"cant changes to the estimated review hours, the reasons for those changes along with updated estimateswill be communicated during routine interactions with the assigned project manager. These estimates are based on the NRC stas initial review of the application and may change due to several factors, including requests for additional information, unanticipated expansion of the review scope, involvement of NRC advisory committees, hearing-related activities, or if the submittal is provided to the NRC in advance of or concurrently with industry program initiatives or pilot applications.
