ANO-1 and ANO Acceptance Review of Request for Alternative ANO-CISI-002 RE: Alternative Frequency to Containment Unbonded Post-Tensioning System lnservice Inspection (L-2022-LLR-0080)

By letter November 10, 2022 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML22316A001), Entergy Operations, Inc. (the licensee) submitted a request to use an alternative to certain requirements of Subsection IWL of the American Society for Mechanical Engineers (ASME), Boiler & Pressure Vessel (BPV) Code,Section XI, Rules for In-Service Inspection of Nuclear Power Plant Components at Arkansas Nuclear One, Units 1 and 2 (ANO-1 and ANO-2). Per the ASME BPV Code, the periodic visual examination and physical testing of containment building concrete are required in accordance with Table IWL-2500-1 L-A, as well as physical testing of unbonded post-tensioning systems in accordance with Table IWL-2500-1 L-B. The licensee also proposed an alternative to the requirements of IWL-2523 to limit the scope of wire strands required to be removed (under IWL-2523.1) and examined (in accordance with IWL-2523.2).

The purpose of this letter is to provide the results of the Nuclear Regulatory Commission (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 Sections 50.55a(a)(z)(1) and 50.55a(a)(z)(2) 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, or that compliance with the specified requirements of Section 50.55a would result in hardship or unusual difficulty without a compensating increase in the level of quality or 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 request 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. You will be advised of any further information needed to support the NRC staffs detailed technical review by separate correspondence.

Based on the information provided in your submittal, the NRC staff has estimated the jobhour expenditures to total approximately 150 hours0.00174 days <br />0.0417 hours <br />2.480159e-4 weeks <br />5.7075e-5 months <br />. The NRC staff expects to complete this review by September 29, 2023. 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, 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.

If you have any questions, please contact me at (301) 415-4037.
