LIC-109 Acceptance - ANO 2 - Proposed Alternative for Implementation of Extended Reactor Vessel In-Service Inspection Interval (ANO2-ISI-24-02) -
Dear Mr. Couture,
By letter dated July 19, 2024 (ADAMS Accession No. ML24201A052), Entergy Operations, Inc., (Entergy)(the licensee) submitted a request to the U.S. Nuclear Regulatory Commission (NRC) for approval of proposed alternative for Arkansas Nuclear One, Unit 2 (ANO-2). Entergy requests NRC approval to extend the In-Service Inspection (ISI) interval for the ANO-2 reactor pressure vessel (RPV) weld examinations from 2027 to end of the current renewed operating license (July 17, 2038). Entergy proposes to implement an alternative to the requirement of American Society of Mechanical Engineers (ASME)
Section XI, IWB 2411, Inspection Program, that volumetric examination of RPV Examination categories B-A and B-D be performed once each 10-year ISI interval. Entergy requests authorization to use the proposed alternative pursuant to 10 CFR 50.55a(z)(1) on the basis that the alternative provides an acceptable level of quality and safety.
The purpose of this e-mail is to provide the results of the 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. Pursuant to Sections 50.55a(z)(1) of Title 10 of the Code of Federal Regulations (10 CFR), the applicant shall demonstrate that the proposed alternatives 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 alternatives 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 licensing request will take approximately 200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> to complete. The NRC staff expects to complete this review in approximately 12 months, which is August 13, 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.
If you have any questions, please contact me.
