ACCEPTANCE REVIEW OF SOUTHERN NUCLEAR OPERATING COMPANYS REQUEST FOR LICENSE AMENDMENT AND EXEMPTION: UNIT 3 AUXILIARY BUILDING WALL 11 SEISMIC GAP REQUIREMENTS (EPID NO. L-2020-LLE-0009)

Dear Mr. Whitley:

By letter dated February 7, 2020 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML20038A939), Southern Nuclear Operating Company (SNC) submitted a request for a license amendment and an exemption to Combined License (COL)

Number NPF-91 for Vogtle Electric Generating Plant, Unit 3. The requested amendment proposes changes to COL Appendix C (and plant-specific Tier 1) and corresponding Tier 2*

and Tier 2 information in the Updated Final Safety Analyses Report (UFSAR). Specifically, the request proposes to modify the north-south minimum seismic gap requirements above grade between the nuclear island and the annex building west of Column Line I from elevation 141 feet through 154 feet to accommodate as-built localized nonconformances.

SNC has also requested an exemption from the provisions of Title 10 of the Code of Federal Regulations (10 CFR) Part 52, Appendix D,Section III.B, Design Certification Rule for the AP1000 Design, Scope and Contents, to allow a departure from the elements of the certification information in Tier 1 of the generic Design Control Document.

The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission staffs acceptance review of these requests. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the staff to complete its detailed technical reviews. 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 the 10 CFR, an amendment to the license must fully describe the changes requested, and follow as far as applicable, the form prescribed for original applications. Section 52.79 of the 10 CFR addresses 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 staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the staff to complete its detailed technical review and make an independent assessment regarding the acceptability, of the proposed amendment and exemption, 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 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 staffs detailed technical review by separate correspondence.

SNC has requested staff approval of this LAR by August 7, 2020. The staff intends to complete this action by November 21, 2020. However, the staff will try to expedite its review to have it completed by August 7, 2020, unless we agree to a different date at a later time due to circumstances beyond our control. The staff estimates that it may take 320 hours13.333 days <br />1.905 weeks <br />0.438 months <br /> to complete this licensing action.

If you have any questions, please contact me at (301) 415-7270 or Cayetano.Santos@NRC.GOV.

Sincerely, Cayetano Santos, Project Manager Vogtle Project Office Office of Nuclear Reactor Regulation Docket No(s): 52-025
