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; PXS/ADS Line Resistance Changes

AGENCY: Nuclear Regulatory Commission.

ACTION: Exemption and combined license amendment; issuance.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) has issued an 
exemption to allow a departure from the certification information of 
Tier 1 of the generic design control document (DCD) and has issued 
License Amendment Nos. 111 and 110 to Combined License (COL) Nos. 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 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 February 28, 2018.

SUPPLEMENTARY INFORMATION: 

I. Background

    The NRC has granted 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 issued License Amendment Nos. 111 and 110 to COL Nos. 
NPF-91 and NPF-92,

[[Page 13532]]

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 Updated Final Safety Analysis Report (UFSAR) Tier 2 
information and plant-specific Tier 1 information, with corresponding 
changes to COL Appendix C. Specifically, the changes relate to the 
passive core cooling system (PXS) low pressure injection and fourth-
stage automatic depressurization system (ADS) flow resistances. This 
includes proposed changes to inspections, tests, and acceptance 
criteria and UFSAR information in various locations.
    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 and the license amendment 
request. The exemption met all applicable regulatory criteria set forth 
in Sec. Sec.  50.12 and 52.7 of 10 CFR, 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. ML18026A571.
    Identical exemption documents (except for referenced unit numbers 
and license numbers) were issued to the licensee 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. ML18026A568 and 
ML18026A567, respectively. The exemption is reproduced (with the 
exception of abbreviated titles and additional citations) in Section II 
of this notice. The amendment documents for COL Nos. NPF-91 and NPF-92 
are available in ADAMS under Accession Nos. ML18026A570 and 
ML18026A569, respectively. A summary of the amendment documents is 
provided in Section III of this notice.

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 March 31, 2017, Southern Nuclear Operating 
Company 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 the license amendment request 
(LAR-17-009) regarding PXS/ADS line resistance changes.''
    For the reasons set forth in Section 3.1 of the NRC staff's safety 
evaluation, 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.
    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 COL 
Appendix C, as described in the request dated March 31, 2017. This 
exemption is related to, and necessary for, the granting of License 
Amendment No. 111 [for Unit 3, 110 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, 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, the licensee requested that the NRC 
amend the COL Nos. NPF-91 and NPF-92 for VEGP, Units 3 and 4. The 
proposed amendment is described in Section I of this notice.
    The Commission has determined that the application for amendment 
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 26128). 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 exemptions and issued these amendments on March 31, 
2017, as part of a combined package to the licensee (ADAMS Accession 
No. ML18026A565).

    Dated at Rockville, Maryland, this 26th day of March 2018.

    For the Nuclear Regulatory Commission.

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