Arkansas Nuclear One, Unit 2 - Acceptance Review of Request to Use Alternative Examination of RV Flange Threads, ANO2-ISI-020 (EPID L-2018-LLR-0003)

By letter dated February 5, 2018 (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML18038A876), Entergy Operations, Inc. (the licensee) submitted an alternative request (ANO2-ISI-020) for Arkansas Nuclear One, Unit 2 (ANO-2). The licensee has requested approval for an alternative to the examination of American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section XI, Examination Category B-G-1, Item Number B6.40, Threads in Flange at ANO-2. The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this relief/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), an applicant or licensee shall demonstrate that the proposed alternative 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 relief/alternative 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 that this licensing request will take approximately 180 hours7.5 days <br />1.071 weeks <br />0.247 months <br /> to complete. The NRC staff expects to complete this review in approximately 12 months, which is February 2019. 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.
