Acceptance Review - Hatch Alternative Request to ISTC-3700 _ RR-V-5 (EPID No. L-2025-LLR-0081)
- Adam, By letter dated August 26, 2025 (Agencywide Documents and Access Management System Accession No. ML25238A190), Southern Nuclear Operating Company (SNC, the licensee) submitted a valve alternative request RR-V-5 associated with the Inservice Testing (IST) Program at Edwin I. Hatch Nuclear Plant (Hatch), Units 1 and 2. SNC proposes an alternative to the ISTC-3700 position verification requirements of the American Society of Mechanical Engineers Operation and Maintenance of Nuclear Power Plants (ASME OM Code). Additionally, the frequency of these tests, along with U.S. Nuclear Regulatory Commission (NRC) Condition 10 CFR 50.55a(b)(3)(xi), would be performed every four (4) years.
The purpose of this e-mail is to provide the results of the NRC staffs acceptance review of this alternative request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.
Pursuant to Section 50.55a(z)(1) of Title 10 of the Code of Federal Regulations (10 CFR), the applicant shall demonstrate that the proposed alternative would provide an acceptable level of quality and safety.
The NRC staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed alternative 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 staffs ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. If additional information is needed, you will be advised by separate correspondence.
Based on the information provided in your submittal, the NRC staff has estimated that this alternative request will take approximately 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> to complete. The NRC staff expects to complete this alternative request by December 31, 2025. If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date or significant 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 staffs initial review of the application, and they could 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.
