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; Addition of Steam Generator System 
(SGS) Thermal Relief Valves

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 AP1000 design control document (DCD) and is 
issuing License Amendment Nos. 99 and 98 to Combined Licenses (COL), 
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 that is requested 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.

SUPPLEMENTARY INFORMATION:

I. Introduction

    The NRC is granting exemptions 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. 99 and 98 to COLs, NPF-91 
and NPF-92, respectively, to the licensee. The exemptions are 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 proposes changes to plant-specific Tier 1 information and 
corresponding changes to Appendix C. Specifically, the licensee 
proposes changes to plant-specific Tier 1, Table 2.2.4-1 and Figure 
2.2.4-1 (Sheets 1 and 2) and corresponding changes to Appendix C of the 
COL to install two main feedwater thermal relief valves and two start-
up feedwater thermal relief valves. The main feedwater thermal relief 
valves will be added to the main feedwater line between the main 
feedwater isolation valves and main feedwater control valves. The 
startup feedwater thermal relief valves will be added between the 
startup feedwater isolation valves and startup feedwater control 
valves. The proposed plant-specific DCD Tier 1 information and 
corresponding changes to Appendix C of the COL require additional 
changes to corresponding Tier 2 information in the Updated Final Safety 
Analysis Report, Chapter 3, ``Design of Structures, Components, 
Equipment, and Systems,'' and Chapter 10, ``Steam and Power 
Conversion.''
    Part of the justification for granting the exemptions was provided 
by the review of the amendments. Because the exemption is necessary in 
order to issue the requested license amendment, the NRC granted the 
exemptions and issued the amendments 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 exemptions met all applicable regulatory criteria set 
forth in 10 CFR 50.12, 10 CFR 52.7, and section VIII.A.4 of appendix D 
to 10 CFR part 52. The license amendments were found to be acceptable 
as well. The combined safety evaluation is available in ADAMS under 
Accession No. ML17263A074.
    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. ML17263A079 and 
ML17263A078, respectively. The exemption is reproduced (with the 
exception of

[[Page 6891]]

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. ML17263A077 and ML17263A075, 
respectively. A summary of the amendment documents is provided in 
Section III of this document.

II. Exemption

    Reproduced below is the exemption document issued to VEGP Units 3 
and Unit 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 April 21, 2017, revised on August 15, 2017, 
and supplemented by letter dated September 18, 2017, the licensee 
requested from the Commission an exemption from the provisions of 10 
CFR part 52, appendix D, section III.B, as part of license amendment 
request 17-012, ``Addition of Steam Generator System (SGS) Thermal 
Relief Valves.''
    For the reasons set forth in Section 3.1, ``Evaluation of 
Exemption,'' of the NRC staff's Safety Evaluation, which can be found 
in ADAMS under Accession No. ML17263A074, 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 Licenses as described in the 
licensee's request dated April 21, 2017, revised on August 15, 2017 and 
supplemented by letter dated September 18, 2017. This exemption is 
related to, and necessary for, the granting of License Amendment Nos. 
99 and 98, which is being issued concurrently with this exemption.
    3. As explained in Section 5.0, ``Environmental Consideration,'' of 
the NRC staff's Safety Evaluation (ADAMS Accession No. ML17263A074), 
these exemptions 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. These exemptions are effective as of the date of its issuance.

III. License Amendment Request

    By letter dated April 21, 2017, revised on August 15, 2017 and 
supplemented by letter dated September 18, 2017, 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 combined license, 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 September 12, 2017 (82 FR 42844). 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 exemption and issued the amendment that the licensee 
requested on April 21, 2017, revised on August 15, 2017, and 
supplemented by letter on September 18, 2017.
    The exemptions and amendments were issued on November 17, 2017, as 
part of a combined package to the licensee (ADAMS Accession No. 
ML17263A070).

    Dated at Rockville, Maryland, this 12th day of February, 2018.

    For the Nuclear Regulatory Commission.
