NUCLEAR REGULATORY COMMISSION

[Docket Nos. 52-025 and 52-026; NRC-2008-0252]


Southern Nuclear Operating Company, Inc.; Vogtle Electric 
Generating Plant, Units 3 and 4; Changes to the Building Gap Between 
the Nuclear Island and Adjacent Buildings

AGENCY: Nuclear Regulatory Commission.

ACTION: Exemption and combined license amendment; issuance.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is granting an 
exemption to allow a departure from the certification information of 
Tier 1 of the generic design control document (DCD) and is issuing 
License Amendment Nos. 127 and 126 to Combined License (COL) Nos. NPF-
91 and NPF-92, respectively. The COLs were issued to Southern Nuclear 
Operating Company, Inc., and Georgia Power Company, Oglethorpe Power 
Corporation, MEAG Power SPVM, LLC, MEAG Power SPVJ, LLC, MEAG Power 
SPVP, LLC, and the City of Dalton, Georgia (the licensee); for 
construction and operation of the Vogtle Electric Generating Plant 
(VEGP) Units 3 and 4, located in Burke County, Georgia.
    The granting of the exemption allows the changes to Tier 1 
information asked for in the amendment. Because the acceptability of 
the exemption was determined in part by the acceptability of the 
amendment, the exemption and amendment are being issued concurrently.

DATES: The exemption and amendment were issued on June 15, 2018.

SUPPLEMENTARY INFORMATION:

I. Introduction

    The NRC is granting an exemption from paragraph B of section III, 
``Scope and Contents,'' of appendix D, ``Design Certification Rule for 
the AP1000,'' to part 52 of title 10 of the Code of Federal Regulations 
(10 CFR), and issuing License Amendment Nos. 127 and 126 to COL Nos. 
NPF-91 and NPF-92, respectively, to the licensee. The exemption is 
required by paragraph A.4 of section VIII, ``Processes for Changes and 
Departures,'' appendix D, to 10 CFR part 52 to allow the licensee to 
depart from Tier 1 information. With the requested amendment, the 
licensee sought proposed changes to plant-specific DCD Tier 2 and Tier 
2* information and related changes to plant-specific Tier 1 
information, with corresponding changes to Inspections, Tests, 
Analyses, and Acceptance Criteria (ITAAC) in COL appendix C. 
Specifically, the proposed changes relax the minimum gap requirement 
above grade between the nuclear island and the annex building/turbine 
building and remove the minimum gap requirement between the nuclear 
island and the radwaste building from the ITAAC and corresponding Tier 
1 information.
    Part of the justification for granting the exemption was provided 
by the review of the amendment. Because the exemption is necessary in 
order to issue the requested license amendment, the NRC granted the 
exemption and issued the amendment concurrently, rather than in 
sequence. This included issuing a combined safety evaluation containing 
the NRC staff's review of both the exemption request and the license 
amendment. The exemption met all applicable regulatory criteria set 
forth in sections 50.12 and 52.7, and section VIII.A.4 of appendix D to 
10 CFR part 52. The license amendment was found to be acceptable as 
well. The combined safety evaluation is available in ADAMS under 
Accession No. ML18120A345.
    Identical exemption documents (except for referenced unit numbers 
and license numbers) were issued to the licensee for VEGP Units 3 and 4 
(COLs NPF-91 and NPF-92). The exemption documents for VEGP Units 3 and 
4 can be found in ADAMS under Accession Nos. ML18120A339 and 
ML18120A340, respectively. The exemption is reproduced (with the 
exception of abbreviated titles and additional citations) in section II 
of this document. The amendment documents for COLs NPF-91 and NPF-92 
are available in ADAMS under Accession Nos. ML18120A341 and 
ML18120A343, respectively. A summary of the amendment documents is 
provided in section III of this document.

II. Exemption

    Reproduced in this notice is the exemption document issued to VEGP 
Unit Nos. 3 and 4. It makes reference to the combined safety evaluation 
that provides the reasoning for the findings made by the NRC (and 
listed under Item 1) in order to grant the exemption:
    1. In a letter dated February 1, 2018, the Southern Nuclear 
Operating Company (SNC) requested from the Commission an exemption to 
allow departures from Tier 1 information in the certified DCD 
incorporated by reference in 10 CFR part 52, appendix D, as part of 
license amendment request 18-002, ``Changes to the Building Gap

[[Page 32157]]

between the Nuclear Island and Adjacent Buildings.''
    For the reasons set forth in section 3.2 of the NRC staff's Safety 
Evaluation, which can be found in ADAMS under Accession No. 
ML18120A345, the Commission finds that:
    A. the exemption is authorized by law;
    B. the exemption presents no undue risk to public health and 
safety;
    C. the exemption is consistent with the common defense and 
security;
    D. special circumstances are present in that the application of the 
rule in this circumstance is not necessary to serve the underlying 
purpose of the rule;
    E. the special circumstances outweigh any decrease in safety that 
may result from the reduction in standardization caused by the 
exemption; and
    F. the exemption will not result in a significant decrease in the 
level of safety otherwise provided by the design.
    2. Accordingly, the licensee is granted an exemption from the 
certified DCD Tier 1 information, with corresponding changes to 
appendix C of the Facility Combined License, as described in the 
licensee's request dated February 1, 2018. This exemption is related 
to, and necessary for the granting of License Amendment No. 127 (Unit 
3) and 126 (Unit 4), which is being issued concurrently with this 
exemption.
    3. As explained in section 5.0 of the NRC staff's Safety Evaluation 
(ADAMS Accession No. ML18120A345), this exemption meets the eligibility 
criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). 
Therefore, pursuant to 10 CFR 51.22(b), no environmental impact 
statement or environmental assessment needs to be prepared in 
connection with the issuance of the exemption.
    4. This exemption is effective as of the date of its issuance.

III. License Amendment Request

    By letter dated February 1, 2018 (ADAMS Accession No. ML18032A359), 
the licensee 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 
February 27, 2018 (83 FR 8519). 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.

IV. Conclusion

    Using the reasons set forth in the combined safety evaluation, the 
staff granted the exemptions and issued the amendments that the 
licensee requested on February 1, 2018.
    The exemptions and amendments were issued on June 15, 2018, as part 
of a combined package to the licensee (ADAMS Accession No. 
ML18120A348).

    Dated at Rockville, Maryland, this 5th day of July 2018.

    For the Nuclear Regulatory Commission.

Chief, Licensing Branch 4, Division of Licensing, Siting, and 
Environmental Analysis, Office of New Reactors.
