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; Slab Thickness Changes between Column 
Lines I to J-1 and 2 to 4 at Elevation 153'-0''

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 Design Certification Rule for 
AP1000 Design Control Document (DCD). The Tier 1 information for which 
a plant-specific departure and exemption is being requested includes a 
change to the thickness of one floor in the auxiliary building located 
between Column Lines I to J-1 and Column Lines 2 to 4 at elevation 
153'-0''. The NRC is issuing License Amendment Nos. 89 and 88 to 
Combined Licenses (COL), NPF-91 and NPF-92. 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.

DATES: The exemption and amendment were issued on October 6, 2017.

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. 89 and 88 to COLs, NPF-91 
and NPF-92, 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 in the form of 
departures from the incorporated plant-specific DCD Tier 2* information 
and involves related changes to the VEGP Units 3 and 4 COL Appendix C 
(and corresponding plant-specific DCD Tier 1) information. Pursuant to 
the provisions of 10 CFR 52.63(b)(1), an exemption from elements of the 
design as certified in the 10 CFR part 52, appendix D, design 
certification rule is also requested for the plant-specific Tier 1 
departures.
    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. ML17254A129.
    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. ML17254A131 and 
ML17254A132, 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. ML17254A127 and 
ML17254A128, 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 August 30, 2016, as supplemented by letter 
dated March 14, 2017, Southern Nuclear Operating Company, Inc., 
(licensee) requested from the Nuclear Regulatory Commission (NRC or 
Commission) an exemption to allow departures from Tier 1 information in 
the certified Design Control Document (DCD) incorporated by reference 
in 10 CFR part 52, appendix D, ``Design Certification Rule for AP1000 
Design,'' as part of license amendment request (LAR) 16-019, ``Slab 
Thickness Changes between Column Lines I to J-1 and 2 to 4 at Elevation 
153'-0''.''
    For the reasons set forth in Section 3.1 of the NRC staff's Safety 
Evaluation that supports this license amendment, which can be found at 
ADAMS Accession Number ML17254A129, the Commission finds that:

[[Page 839]]

    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, as described in the licensee's 
request dated August 30, 2016, as supplemented by letter dated March 
14, 2017. This exemption is related to, and necessary for, the granting 
of License Amendments No. 89 and 88, which is being issued concurrently 
with this exemption.
    3. As explained in Section 5 of the NRC staff's Safety Evaluation 
that supports this license amendment (ADAMS Accession Number 
ML17254A129), 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 August 30, 2016, as supplemented by letter dated 
March 14, 2017 (ADAMS Accession Nos. ML16243A373 and ML17007A159, 
respectively), 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 
March 28, 2017 (82 FR 15377). 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 August 30, 2016, and supplemented by letter dated March 
14, 2017. The exemption and amendment were issued on October 6, 2017, 
as part of a combined package to the licensee (ADAMS Accession No. 
ML17254A125).

    Dated at Rockville, Maryland, this 2nd day of January 2, 2018.

    For the Nuclear Regulatory Commission.
