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. 140 and 139 to Combined Licenses (COLs), 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 (collectively SNC); 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. 140 and 139 to COLs, NPF-
91 and NPF-92, respectively, to SNC. 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 SNC to depart from 
Tier 1 information. With the requested amendment, SNC sought proposed 
changes that would revise the Updated Final Safety Analysis Report in 
the form of departures from the plant-specific Design Control Document 
(DCD) Tier 2 information. The proposed amendment also involves changes 
to plant-specific Tier 1 information with corresponding changes to the 
associated COL Appendix C information. Specifically, the amendment 
proposes changes to plant-specific Tier 1 (and COL Appendix C) to 
reflect a new design of containment sump level sensors, which affects 
the acceptance criterion for the detected containment sump level change 
test and the associated minimum detectable unidentified leakage rate in 
plant-specific DCD Tier 2 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 10 CFR 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. ML18220B104.
    Identical exemption documents (except for referenced unit numbers 
and license numbers) were issued to SNC for VEGP Units 3 and 4 (COL 
Nos. NPF-91 and NPF-92). The exemption documents for VEGP Units 3 and 4 
can be found in ADAMS under Accession Nos. ML18220B097 and ML18220B098, 
respectively. The exemption is reproduced (with the exception of 
abbreviated titles and additional citations) in Section II of this 
document. The amendment documents for COL Nos. NPF-91 and NPF-92 are 
available in ADAMS under Accession Nos. ML18220B099 and ML18220B100, 
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 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 26, 2018, 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 18-014, ``Containment Sump 
Level Instrumentation.''
    For the reasons set forth in Section 3.1 [sic] of the NRC staff's 
Safety Evaluation, which can be found in ADAMS under Accession No. 
ML18220B104, 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 26, 2018. This exemption is related to, 
and necessary for the granting of License Amendment No. 140 [for Unit 3 
and No. 139 for 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. ML18220B104), 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 26, 2018 (ADAMS Accession No. ML18116A138), 
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 
June 19, 2018 (83 FR 28463). 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

[[Page 53317]]

granted the exemptions and issued the amendments that SNC requested on 
April 26, 2018. The exemption and amendment were issued on August 24, 
2018, as part of a combined package to SNC (ADAMS Accession No. 
ML18220B095).

    Dated at Rockville, Maryland, this 17th day of October 2018.

    For the Nuclear Regulatory Commission.
