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; Pipe Rupture Hazard and Flooding
Analysis
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 elements of the certification
information of Tier 1 of the generic AP1000 design control document
(DCD) and is issuing License Amendment Nos. 107 and 106 to Combined
Licenses (COL), NPF-91 and NPF-92, respectively. The COLs were issued
to Southern Nuclear Operating Company, 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 referred to as 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.
The exemption revises the plant-specific Tier 1 information and
corresponding changes to COL Appendix C, and the amendment changes the
associated plant-specific DCD Tier 2 material incorporated into the
VEGP Updated Final Safety Analysis Report (UFSAR), to address
mitigation of fire protection system flooding of the Auxiliary Building
identified following completion of the pipe rupture hazards analysis
for the VEGP Units 3 and 4.
DATES: The exemption and amendment were issued on February 1, 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. 107 and 106 to COLs, NPF-
91 and NPF-92, respectively, to the licensee. The
[[Page 10928]]
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 proposed changes to plant-specific Tier 1
information and corresponding changes to COL Appendix C and associated
plant-specific DCD Tier 2 material incorporated into the VEGP UFSAR, by
revising information to address the need for mitigation of fire
protection system flooding of the Auxiliary Building identified during
completion of the pipe rupture hazards analysis. The exemption 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
amendment met all applicable regulatory criteria and was found to be
acceptable as well. The combined safety evaluation is available in
ADAMS under Accession No. ML18017A261.
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. ML18017A608 and
ML18017A524, 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. ML18017A386 and
ML18017A577, 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 March 31, 2017, as supplemented and revised by
letters dated August 21, October 9, November 1, December 1 and December
15, 2017, and January 3, 2018, Southern Nuclear Operating Company
requested from the Nuclear Regulatory Commission (NRC or Commission) an
exemption to allow departures from Tier 1 information in the certified
DCD incorporated by reference in Title 10 10 CFR part 52, appendix D,
``Design Certification Rule for the AP1000 Design,'' as part of license
amendment request (LAR) 17-010, ``Request for License Amendment and
Exemption: Pipe Rupture Hazard and Flooding Analyses.''
For the reasons set forth in Section 3.1 of the NRC staff's Safety
Evaluation, which can be found at ADAMS Accession No. ML18017A261 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 AP1000 DCD Tier 1 information, with corresponding changes to
Appendix C of the Facility Combined License as described in the request
dated March 31, 2017, as supplemented and revised by letters dated
August 21, October 9, November 1, December 1 and December 15, 2017 and
January 3, 2018. This exemption is related to, and necessary for, the
granting of License Amendment Nos.107 and 106, which is issued
concurrently with this exemption.
3. As explained in Section 6.0 of the NRC staff's Safety Evaluation
(ADAMS Accession Number ML18017A261, 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 March 31, 2017 (ADAMS Accession No. ML17090A570),
and revised and supplemented by letters dated August 21, October 9,
November 1, December 1, and December 15, 2017, and January 3, 2018
(ADAMS Accession Nos. ML17233A325, ML17282A014, ML17305B507,
ML17335A762, ML17349A928, and ML18003B082, 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
June 6, 2017 (82 FR 26123). 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 by letter dated March 31, 2017, (ADAMS Accession No.
ML17090A570) and revised and supplemented by letters dated August 21,
October 9, November 1, December 1, and December 15, 2017, and January
3, 2018 (ADAMS Accession Nos. ML17233A325, ML17282A014, ML17305B507,
ML17335A762, ML17349A928, and ML18003B082, respectively).
The exemption and amendment were issued to the licensee on February
1, 2018, as part of a combined package (ADAMS Accession No.
ML18017A721).
Dated at Rockville, Maryland, this 7th day of March, 2018.
For the Nuclear Regulatory Commission.

Chief, Licensing Branch 4, Division of New Reactor Licensing, Office of
