Acceptance Review: Comanche Peak multiple relief requests for Unit 2 third inservice inspection interval due to impracticality (EPID: L-2024-LLR-0053 through -0058)
By letter dated August 13, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24226A120), Vistra Operations Company LLC (the licensee) submitted multiple relief requests for Comanche Peak Nuclear Power Plant, Unit 2, third ten-year inservice inspection interval from Title 10 of the Code of Federal Regulations (10 CFR) 50.55(a) inspection requirements due to impracticality. The August 13, 2024, letter replaced a licensee letter dated August 5, 2024 (ML24218A217) for these multiple relief requests. The purpose of this email is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this 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.
The NRC staff has reviewed the licensees 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 change 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, the licensee will be advised by separate correspondence.
Based on the information provided in the licensees relief requests B-1, B-2, B-3, B-4, C-1, and C-2, the NRC staff has estimated that these relief requests will take approximately 160, 120, 120, 160, 160, and 160 hours0.00185 days <br />0.0444 hours <br />2.645503e-4 weeks <br />6.088e-5 months <br />, respectively, to complete. The NRC staff expects to complete this review by September 18, 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 complexity and uniqueness of the review, requests for additional information, unanticipated addition of scope to the review, and review by NRC advisory committees or hearing-related activities. Additional delay may occur if the submittal is provided to the NRC in advance or in parallel with industry program initiatives or pilot applications.
