Virgil C. Summer, Unit 1 - Acceptance of Requested License Amendment Request regarding Reactor Coolant System Operational Leakage TS Surveillance Requirement 4.4.6.2.2(a) (EPID No. L-2018-LLA-0267)

Dear Mr. Moore,

By letter dated October 8, 2018 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML18281A014), the South Carolina Electric & Gas Company submitted an amendment request to revise the Virgil C.

Summer Nuclear Plant, Unit 1, Reactor Coolant System (RCS) Operational Leakage Technical Specifications (TS)

Surveillance Requirement (SR) 4.4.6.2.2. The proposed amendment would revise the surveillance frequency of TS 4.4.6.2.2 (a) to allow the RCS pressure isolation valve leakage test to be extended to a performance-based frequency not to exceed 3 refueling outages or 60 months following two consecutive satisfactory tests.

The purpose of this letter is to provide the results of NRC staffs acceptance review. 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. Consistent with Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), an amendment to the license (including the technical specifications) must fully describe the changes requested, and following as far as applicable, the form prescribed for original applications. Section 50.34 of 10 CFR addresses the content of technical information required. This section stipulates that the submittal address the design and operating characteristics, unusual or novel design features, and principal safety considerations.

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. 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 135 hours5.625 days <br />0.804 weeks <br />0.185 months <br /> to complete. The NRC staff expects to complete this review by October 2019, as requested in your application. 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 Shawn Williams at (301) 415-1009.
