Nuclear Regulatory Commission.
Exemption and combined license amendment; issuance.
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 Nos. 78 and 77 to Combined Licenses (COLs), NPF-91 and NPF-92 for the Vogtle Electric Generating Plant (VEGP) Units 3 and 4, respectively. The COLs were issued to Southern Nuclear Operating Company (SNC), 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 Start Printed Page 27293Vogtle Electric Generating Station (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 and amendment were issued on May 25, 2017.

Start Supplemental Information
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. 78 and 77 to COLs, NPF-91 and NPF-92, respectively, to the licensee. The exemption is required by Paragraph A.4 of Section VIII, “Processes for Changes and Departures,” of 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 request (LAR) revises the inspections, tests, analyses, and acceptance criteria (ITAAC) in COL Appendix C Table 2.3.2-4, ITAAC No. 2.3.02.8a.ii to state that the volume in the boric acid storage tank is at least 70,000 gallons between the tank suction point and the tank overflow; and COL Appendix C Table 2.3.2-4, ITAAC No. 2.3.02.8a.iii to state that the total chemical and volume control system makeup flow to the reactor coolant system is less than or equal to 175 gpm.
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 §§ 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. ML17072A320.
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. ML17072A318 and ML17072A315, 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. ML17072A316 and ML17072A314, respectively. A summary of the amendment documents is provided in Section III of this document.
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 an application dated October 26, 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 amendment request 15-028, “Boric Acid Storage Tank Suction Point ITAAC 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. ML17072A320, 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 boric acid storage tank (BAST) available volume at the suction point, chemical and volume control system (CVS) makeup flow rate, and BAST installation, as described in the licensee's request dated October 26, 2016. This exemption is related to, and necessary for the granting of License Amendment Nos. 78 and 77 for Units 3 and 4, respectively, 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. ML17072A320), this exemption meets the eligibility criteria for categorical exclusion set forth in 10 Start Printed Page 27294CFR 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 October 26, 2016 (ADAMS Accession No. ML16300A325), 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 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 December 20, 2016 (81 FR 92872). 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.
Using the reasons set forth in the combined safety evaluation, the staff granted the exemption and issued the amendment that the licensee requested on October 26, 2016. The exemption and amendment were issued on May 25, 2017, as part of a combined package to the licensee (ADAMS Accession No. ML17072A312).
