McGuire Nuclear Station, Units 1 and 2 - Acceptance of Requested Licensing Action Re: NSWS One-Time CT Extension (CACs MG0242 & 3, EPID L-2017-LLA-0299)

Lee, By letter dated September 14, 2016, Duke Energy submitted a license amendment request (LAR) for McGuire Nuclear Station, Units 1 and 2. The LAR revises the Technical Specifications to allow temporary changes to TS 3.5.2, Emergency Core Cooling System (ECCS) - Operating; TS 3.6.6, Containment Spray System (CSS); TS 3.7.5, Auxiliary Feedwater (AFW) System; TS 3.7.6, Component Cooling Water (CCW) System; TS 3.7.7, Nuclear Service Water System (NSWS); TS 3.7.9, Control Room Area Ventilation System (CRAVS); TS 3.7.11 , Auxiliary Building Filtered Ventilation Exhaust System (ABFVES), and TS 3.8.1 , AC Sources- Operating. The proposed amendment will permit the 'A' Train NSWS to be inoperable for a total of 14 days to address a operable but non-conforming condition on the 'A' Train supply piping from the Standby Nuclear Service Water Pond (SNSWP).

The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this LAR. 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 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 300 hours12.5 days <br />1.786 weeks <br />0.411 months <br /> to complete. Although the NRC staff typically reviews LARs in a 12-month timeframe, we will be working to support the licensees requested January 31, 2018 approval date. 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.

Thanks Mike Michael Mahoney McGuire and Catawba Project Manager, Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation U. S. Nuclear Regulatory Commission 1
