NUCLEAR REGULATORY COMMISSION

[Docket Nos. 52-025, and 52-026; NRC-2008-0252]


Vogtle Electric Generating Station, Units 3 and 4; Southern 
Nuclear Operating Company; Changes to the Chemical Volume Control 
System

AGENCY: Nuclear Regulatory Commission.

ACTION: Exemption and combined license amendment; issuance.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is both granting 
an exemption to allow a departure from the certification information of 
Tier 1 of the generic design control document (DCD) and issuing License 
Amendment No. 12 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, Municipal Electric 
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 amendment 
requests changes that modify the Chemical and Volume Control System 
(CVS), including changes to information located in Tier 1 Tables 2.3.2-
1 and 2.3.2-2, and Tier 1 Figures 2.2.1-1 and 2.3.2-1. The granting of 
the exemption allows the changes to Tier 1 information as specified in 
the license amendment request. 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 issuing 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 License Amendment No. 12 to COLs, NPF-91 and NPF-92, 
issued 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 to modify the design 
of the CVS. As part of this request, the licensee needed to change 
information located in Tier 1 Tables 2.3.2-1 and 2.3.2-2, and Tier 1 
Figures 2.2.1-1 and 2.3.2-1. These changes were necessary as part of a 
design modification which provides a spring-assisted check valve to the 
Reactor Coolant System Purification Return Line in order to maintain 
overpressure protection, replaces an isolation check valve in the CVS 
with an air operated globe valve, and separates the zinc and hydrogen 
injection lines.
    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, 10 CFR 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. ML13172A326.
    Identical exemption documents (except for referenced unit numbers 
and license numbers) were issued to the licensee for Vogtle Units 3 and 
4 (COLs NPF-91 and NPF-92). These documents can be found in ADAMS under 
Accession Nos. ML13172A218 and ML13172A223. 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. ML13172A242 and 
ML13172A299. A summary of the amendment documents is provided in 
Section III of this document.

II. Exemption

    Reproduced below is the exemption document issued to Vogtle Unit 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 January 11, 2013, and as supplemented by 
letters dated February 27, 2013 and June 11, 2013, the licensee 
requested from the Commission an exemption from the provisions of 10 
CFR part 52, appendix D, Section III.B, as part of license amendment 
request 13-002, ``Changes to the Chemical and Volume Control System 
(CVS) (LAR-13-002).
    For the reasons set forth in Section 3.1, ``Evaluation of 
Exemption,'' of the NRC staff's Safety Evaluation, which can be found 
in ADAMS under Accession No. ML13172A326, 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 to the 
provisions of 10 CFR part 52, appendix D, Section III.B, to allow 
deviations from the certified DCD Tier 1 Tables 2.3.2-1 and 2.3.2-2, 
and Figures 2.2.1-1 and 2.3.2-1, as described in the licensee's request 
dated January 11, 2013, and as supplemented on February 27, 2013 and 
June 11, 2013. This exemption is related to, and necessary for the 
granting of License Amendment No. 12, which is being issued 
concurrently with this exemption.
    3. As explained in Section 5.0, ``Environmental Consideration,'' of 
the NRC staff's Safety Evaluation (ADAMS Accession No. ML13172A326), 
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 July 25, 2013.

III. License Amendment Request

    By letter dated January 11, 2013, the licensee requested that the 
NRC amend the COLs for VEGP, Units 3 and 4, COLs NPF-91 and NPF-92. The 
licensee supplemented this application on February 27, 2013, and June 
11, 2013. The proposed amendment would depart from the UFSAR Tier 1 
material, and would revise the associated material that has been 
included in Appendix C of each of the VEGP, Units 3 and 4, COLs. The 
requested amendment will revise the Tier 2 UFSAR information pertaining 
to the CVS, found throughout the UFSAR. These Tier 2 changes require 
modifications to particular information located in Tier 1 Tables 2.3.2-
1 and 2.3.2-2, and Tier 1 Figures 2.2.1-1 and 2.3.2-1. These changes 
were necessary as part of a design modification which provides a 
spring-assisted check valve to the Reactor Coolant System Purification 
Return Line in order to maintain overpressure protection, replaces an 
isolation check valve in the CVS with an air operated globe valve, and 
separates the zinc and hydrogen injection lines.
    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.

[[Page 50457]]

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 combined license, 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 4, 2013 (78 FR 14137). The supplements had no effect 
on the no significant hazards consideration determination and no 
comments were received during the 60-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 January 11, 2013, and supplemented by letters February 27, 
2013 and June 11, 2013. The exemption and amendment were issued on July 
25, 2013 as part of a combined package to the licensee. (ADAMS 
Accession No. ML13172A181).

    Dated at Rockville, Maryland, this 12th day of August, 2013.
