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. 93 and 92 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, Authority of Georgia, 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.

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. 93 and 92 to COLs, 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 the Updated Final Safety Analysis 
Report (UFSAR) in the form of departures from the plant-specific Design 
Control Document (DCD) Tier 2 information, and involves changes to 
related plant-specific DCD Tier 1 information, with corresponding 
changes to the associated COL appendix C information. The proposed 
changes revise the COLs concerning the minimum chilled water flowrates 
to the supply air handling units serving the main control room and the 
Class 1E electrical rooms, and the unit coolers serving the normal 
residual heat removal system and chemical and volume control system 
makeup pump rooms.
    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 Sec. Sec.  50.12, 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. ML17208A163.
    Identical exemption documents (except for referenced unit numbers 
and

[[Page 57004]]

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. ML17205A478 and 
ML17205A479, 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. ML17205A476 and 
ML17205A477, 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 27, 2017, as supplemented by letter 
dated August 3, 2017, Southern Nuclear Operating Company, Inc., 
(licensee) requested from the NRC an exemption to allow departures from 
Tier 1 information in the certified Design Control Document (DCD) 
incorporated by reference in part 52 of title 10 of the Code of Federal 
Regulations (10 CFR), appendix D, ``Design Certification Rule for the 
AP1000 Design,'' as part of license amendment request (LAR) 17-015, 
``Central Chilled Water System (VWS) Optimization Changes.''
    For the reasons set forth in Section 3.1 of the NRC staff's Safety 
Evaluation, which can be found in ADAMS under Accession No. 
ML17208A163, 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 April 27, 2017, as supplemented by letter 
dated August 3, 2017. This exemption is related to, and necessary for 
the granting of License Amendment Nos. 93 (Unit 3) and 92 (Unit 4), 
which is being issued concurrently with this exemption.
    3. As explained in Section 6.0 of the NRC staff's Safety Evaluation 
(ADAMS Accession No. ML17208A163), 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 April 27, 2017 (ADAMS Accession No. ML17118A049), 
as supplemented by letter dated August 3, 2017 (ADAMS Accession No. 
ML17215B187), 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 
June 19, 2017 (82 FR 27891). 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 27, 2017, as supplemented by letter dated August 3, 
2017.
    The exemption and amendment were issued on October 20, 2017, as 
part of a combined package to the licensee (ADAMS Accession No. 
ML17205A473).

    Dated at Rockville, Maryland, this 28th day of November 2017.
