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; Design Reliability Assurance Program 
(D-RAP) Changes

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 certification information of 
Tier 1 of the generic design control document (DCD) and is issuing 
License Amendment No. 67 to Combined Licenses (COLs), 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 January 30, 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 No. 67 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 that 
would revise the updated final safety analysis report (UFSAR) in the 
form of departures from the incorporated plant-specific DCD Tier 2 
information. The proposed amendment also involves related changes to 
plant-specific Tier 1 information, with corresponding changes to the 
associated COL Appendix C information. Specifically, the license 
amendment revises the Design Reliability Assurance Program (D-RAP) to 
identify the covers for the in-containment refueling water storage tank 
(IRWST) vents and overflow weirs as the risk-significant components 
included in the D-RAP and to identify that the field control relays of 
each rod drive motor-generator sets are a part of the rod drive power 
supply control cabinets in which the relays are located.
    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. ML16343A760.
    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. ML16343A775 and 
ML16343A789, 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. ML16343A773 and 
ML16343A786, 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 23, 2016, as supplemented by letter 
dated December 7, 2016, the licensee 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

[[Page 14767]]

amendment request 16-017, ``Design Reliability Assurance Program (D-
RAP) 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. 
ML16343A760, 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 related to the in-containment 
refueling water storage tank vents and overflow weirs, the rod drive 
motor-generator sets field control relays, and the rod drive power 
supply control cabinets, as described in the licensee's request dated 
August 23, 2016, as supplemented by letter dated December 7, 2016. This 
exemption is related to, and necessary for the granting of License 
Amendment No. 67, 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. ML16343A760), 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 23, 2016 (ADAMS Accession No. ML16236A266), 
as supplemented by letter dated December 7, 2016 (ADAMS Accession No. 
ML16342C564), 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 document.
    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 COL, 
proposed no significant hazards consideration determination, and 
opportunity for a hearing in connection with these actions, was 
published in the Federal Register on October 25, 2016 (81 FR 73439). 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 23, 2016, as supplemented by letter dated December 
7, 2016. The exemption and amendment were issued on January 30, 2017, 
as part of a combined package to the licensee (ADAMS Accession No. 
ML16343A657).

    Dated at Rockville, Maryland, this 13th day of March 2017.

    For the Nuclear Regulatory Commission.
