May 15, 2019 MEMORANDUM TO: Jennifer Dixon-Herrity, Chief Licensing Branch 2 Division of Licensing, Siting, and Environmental Analysis Office of New Reactors FROM: Chandu Patel, Senior Project Manager /RA/

Licensing Branch 2 Division of Licensing, Siting, and Environmental Analysis Office of New Reactors

SUBJECT:

AUDIT PLAN FOR VOGTLE ELECTRIC GENERATING PLANT UNITS 3 AND 4, REQUEST FOR LICENSE AMENDMENT:

CREDITING PREVIOUSLY COMPLETED ADS BLOWDOWN FIRST THREE PLANT TESTS (LAR 19-006)

By letter dated April 26, 2019 (Agencywide Documents Access and Management System (ADAMS) Accession Number ML19119A249), Southern Nuclear Operating Company (the licensee) requested an amendment to Combined License (COL) Numbers NPF-91 and NPF-92, for Vogtle Electric Generating Plant (VEGP) Units 3 and 4.

The requested amendment requires changes to the COL Conditions and Updated Final Safety Analysis Report in the form of departures from the incorporated plant-specific Design Control Document Tier 2* and Tier 2 information and related changes to the VEGP Units 3 and 4 COL.

The requested amendment includes changes to credit the previously completed Automatic Depressurization System (ADS) Blowdown first three plant tests as described in the licensing basis documents, including COL Condition 2.D.(2)(a). Specifically, the proposed changes would revise the COL, License Condition 2.D.(2)(a)2, by removing the requirement to perform the ADS Blowdown first three plant test during preoperational testing.

AUDIT OF REPORTS AND CALCULATIONS IN SUPPORT OF A REQUEST FOR A LICENSE AMENDMENT RELATED TO CREDITING PREVIOUSLY COMPLETED AUTOMATIC DEPRESSURIZATION SYSTEM (ADS)

BLOWDOWN FIRST THREE PLANT TESTS SOUTHERN NUCLEAR OPERATING COMPANY VOGTLE ELECTRIC GENERATING PLANT, UNITS 3 AND 4 Docket Nos.52-025 and 52-026 The purpose of the audit is to review the documentation and calculations needed by the U.S Nuclear Regulatory Commission (NRC) staff to verify the information and conclusions in the Request for License Amendment: Crediting Previously Completed ADS Blowdown First Three Plant Tests (LAR 19-006) submitted by Southern Nuclear Operating Company (SNC) for the Vogtle Electric Generating Plant (VEGP), Units 3 and 4 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML19119A249).

A.

Background:

In LAR 19-006, SNC requests changes to the Updated Final Safety Analysis Report (UFSAR) in the form of departures from the incorporated plant-specific Design Control Document Tier 2*

and Tier 2 information and related changes to the VEGP Units 3 and 4 Combined License (COL).

The LAR includes changes to credit previously completed Automatic Depressurization System (ADS) Blowdown first three plant tests as described in the licensing basis documents, including COL Condition 2.D.(2)(a). SNC requested prior NRC approval because the proposed changes impact the COL and plant-specific Tier 2* information.

B. Regulatory Audit Basis This regulatory audit is based on the following:

  • VEGP Unit 3, Current Facility Combined License NPF-91, Revised April 30, 2019, License Condition 2.D.(2)(a) (ADAMS Accession No. ML14100A106).
  • VEGP Unit 4, Current Facility Combined License NPF-92, Revised April 30, 2019, License Condition 2.D.(2)(a) (ADAMS Accession No. ML14100A135).

C. Regulatory Audit Scope and Methodology The audit team will view the documentation and calculations that provide the technical support for LAR 19-006. In addition, the audit team might request to discuss with subject matter expert(s) (1) potential differences between VEGP Units 3 and 4, and the plants for which testing has been conducted, (2) quality assurance of the test data, (3) physical phenomena

observed in the test data, and (4) design changes to the ADS valves in response to operating experience.

D. Information and Other Material Necessary for the Regulatory Audit The staff requests that the following documents be made available to the staff in the electronic reading room:

a) Applicable Quality Assurance (QA) requirements, administrative procedures, and ADS Blowdown test specification, test procedures, test diagnostic equipment, test acceptance criteria, blowdown test simulation, test results, test analysis methods, test reports, test anomaly resolution, and post-test analyses by Westinghouse Electric Company.

b) Reviews of QA requirements, administrative procedures, and ADS Blowdown test specification, test procedures, test diagnostic equipment, test acceptance criteria, blowdown test simulation, test results, test analysis methods, test reports, test anomaly resolution, and post-test analyses documented by the licensee.

c) Test observations documented by the licensee.

d) Disposition of inconsistencies in test procedures and other aspects noted in LAR 19-006.

e) Documentation of resolution of operational experience that resulted in design changes to ADS valves in support of the ADS Blowdown test that will be addressed as part of ADS valve qualification in accordance with American Society of Mechanical Engineers (ASME) Standard QME-1-2007, Qualification of Active Mechanical Equipment Used in Nuclear Power Plants, as accepted in NRC Regulatory Guide 1.100 (Revision 3),

Seismic Qualification of Electrical and Active Mechanical Equipment and Functional Qualification of Active Mechanical Equipment for Nuclear Power Plants.

f) Report documenting the review of Sanmen and Haiyang nuclear power plant design changes for the critical design attributes for the ADS Blowdown test.

Other documents may be requested based on the staffs review of the above documents.

The staff acknowledges and will observe appropriate handling and protection of proprietary information made available for the audit.
