Acceptance Review - Shearon Harris Nuclear Power Plant, Unit 1 - RA-20-0312

-Relief Request, Service Water Pinhole Leak in a Socket Weld, Inservice Inspection (L-2020-LLR-0143)

Hi Chuck, By letter RA-20-0312, dated November 4, 2020 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML20309A774), Duke Energy Carolinas, LLC (the licensee) submitted a relief request for Shearon Harris Nuclear Power Plant, Unit 1. The licensee requested Nuclear Regulatory Commission (NRC) approval for deferral of an American Society of Mechanical Engineers (ASME) Code repair of a through-wall leak in a line in the Emergency Service Water (ESW).

The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this amendment 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)(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 amendment 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 150 hours0.00174 days <br />0.0417 hours <br />2.480159e-4 weeks <br />5.7075e-5 months <br /> to complete. The NRC staff expects to complete this review in approximately 5 months, which is April 1, 2021. 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.

If you have any questions, please contact me.
