ACCEPTANCE REVIEW OF SOUTHERN NUCLEAR OPERATING COMPANYS CREDITING PREVIOUSLY COMPLETED FIRST PLANT ONLY STARTUP TESTS (EPID NO. L-2019-LLA-0138)

Dear Mr. Whitley:

By letter dated June 28, 2019 (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML19179A209), Southern Nuclear Operating Company (SNC) submitted a request for a license amendment to Combined License (COL) Numbers NPF-91 and NPF-92, for the Vogtle Electric Generating Plant Units 3 and 4, respectively. The requested amendment proposes changes to credit previously completed first plant only startup testing described in licensing basis documents, including License Condition 2.D.(4)(b) and 2.D.(5)(b) of the COL related to the Natural Circulation (Steam Generator) test, the Rod Cluster Control Assembly (RCCA) Out of Bank Measurements, the Load Demonstration, and the Passive Residual Heat Exchanger Test.

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, 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 December 31, 2019. The staff intends to complete this action by April 22, 2020. However, the staff will try to expedite its review to have it completed by December 31, 2019, unless we agree to a different date at a later time due to circumstances beyond our control. The staff estimates that it may take 425 hours17.708 days <br />2.53 weeks <br />0.582 months <br /> to complete this licensing action.

If you have any questions, please contact me at (301) 415-1530 or Jennivine.rankin@nrc.gov.
