Nuclear Regulatory Commission.
Exemption and Combined License Amendment: Issuance.
The U.S. Nuclear Regulatory Commission (NRC) is issuing an exemption to allow a departure from the certification information of Tier 1 of the generic design control document (DCD) and License Amendment No. 6 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 changes requested improve the clarity and accuracy of the Tier 1 information located in Table 3.3-1, “Definition of Wall Thicknesses for Nuclear Island Buildings, Turbine Buildings, and Annex Building,” which describes wall and floor thicknesses in the plant. The granting of the exemption allows the changes 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.

Start Supplemental Information
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. 6 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. The licensee sought to change the Tier 1 information located in Table 3.3-1 of its Updated Final Safety Analysis Report (UFSAR). These changes sought to improve the clarity and accuracy of the table so that it could be more easily inspected during Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) closure.
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. ML13074A178.
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. ML13112A231 and ML13112A242. The exemption is reproduced (with the exception of Start Printed Page 32279abbreviated 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. ML13074A151 and ML13074A160. A summary of the amendment documents is provided in Section III of this document.
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 September 21, 2012, and as supplemented by letters dated October 29, 2012, and January 25, 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 12-008, “Definition of Wall Thicknesses for Nuclear Island Buildings, Turbine Buildings, and Annex Building” (LAR 12-008).
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. ML13074A178, 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 Tier 1 certification information in Table 3.3-1 of the certified Design Control Document, as described in the licensee's request dated September 21, 2012, and as supplemented on October 29, 2012, and January 25, 2013. This exemption is related to, and necessary for the granting of License Amendment No. 6, 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. ML13074A178), 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 May 8, 2013.
III. License Amendment Request
By letter dated September 21, 2012, 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 October 29, 2012, and January 25, 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. Specifically the requested amendment will revise the Tier 1 information located in Table 3.3-1, to correctly translate information found in Tier 1 and Tier 2 drawings. No physical changes or design changes were requested as part of this amendment, only the presentation of design information in Table 3.3-1 changed.
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 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 November 13, 2012 (77 FR 67685). 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.
Using the reasons set forth in the combined safety evaluation, the staff granted the exemption and issued the amendment that the licensee requested on September 21, 2012, and supplemented by letters dated October 29, 2012, and January 25, 2013. The exemption and amendment were issued on May 8, 2013 as part of a combined package to the licensee. (ADAMS Accession No. ML13074A139).
