I. Introduction

The NRC is issuing VEGP Units 3 and 4 License Amendment Nos. 179 and 178 to COLs NPF-91 and NPF-92. With the requested amendment, SNC proposed changes to the VEGP Units 3 and 4 Cyber Security Plan (CSP) to identify the VEGP Units 1 and 2 CSP for cyber security protection of digital assets in common systems, to align language in the VEGP Units 3 and 4 CSP with the corresponding elements of the NRC-endorsed CSP template contained in Nuclear Energy Institute (NEI) 08-09, Revision 6, including Addendum 1, and to enhance certain controls for the VEGP Units 3 and 4 protection and safety monitoring system.

II. License Amendment Request

By letter dated December 20, 2019, and available in ADAMS under Accession No. ML19354B986, SNC requested that the NRC amend the COLs for VEGP, Units 3 and 4, COLs NPF-91 and NPF-92. The proposed amendment is described in Section I of this Federal Register notice.

The Commission has determined for these amendments that the application complies with the standards and requirements of the Atomic Energy Act of 1954, as amended (the Act), and the Commission's rules and regulations. The Commission has made appropriate findings as required by the Act and the Commission's rules and regulations in 10 CFR Chapter I, which are set forth in the license amendment.

A notice of consideration of issuance of amendment to facility operating license or COL, as applicable, proposed no significant hazards consideration determination, and opportunity for a hearing in connection with these actions, was published in the Federal Register on January 2, 2020 (85 FR 144). No comments were received during the 30-day comment period.

The Commission has determined that these amendments satisfy the criteria for categorical exclusion in accordance with 10 CFR 51.22. Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared for these amendments.

III. Conclusion

Using the reasons set forth in the combined safety evaluation, the staff approved the amendment and it was issued to SNC on April 30, 2020, as part of a combined package (ADAMS Package Accession No. ML20057E069).
