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. 49 to Combined Licenses (COLs), NPF-93 and NPF-94. The COLs were issued to South Carolina Electric & Gas (SCE&G) (the licensee); for construction and operation of the Virgil C. Summer Nuclear Station (VCSNS) Units 2 and 3, located in Fairfield County, South Carolina. 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 combined license amendment referenced in this document are available on July 28, 2016.

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. 49 to COLs, NPF-93 and NPF-94, 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 ASME safety classification and transition location, equipment orientation and removal, and identification of the number of Start Printed Page 49691emergency air storage tanks. The proposed changes to the Main Control Room Emergency Habitability System (VES) revises Tier 1 and corresponding information in COL Appendix C, Figure 2.2.5-1. It also revises Tier 2 information in the Updated Final Safety Analysis Report.

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. ML16095A202.

Identical exemption documents (except for referenced unit numbers and license numbers) were issued to the licensee for VCSNS Units 2 and 3 (COLs NPF-93 and NPF-94). The exemption documents for VCSNS Units 2 and 3 can be found in ADAMS under Accession Nos. ML16095A141 and ML16095A144, 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-93 and NPF-94 are available in ADAMS under Accession Nos. ML16095A132 and ML16095A137, respectively. A summary of the amendment documents is provided in Section III of this document.

II. Exemption

Following is the exemption document issued to VCSNS Units 2 and Unit 3. 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 June 30, 2015, 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 15-03, “Main Control Room Emergency Habitability System (VES) Design Changes (LAR 15-03).”

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. ML16095A202, 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, as described in the licensee's request dated June 30, 2015. This exemption is related to, and necessary for the granting of License Amendment No. 49, 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. ML16095A202), 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 June 30, 2015, the licensee requested that the NRC amend the COLs for VCSNS, Units 2 and 3, COLs NPF-93 and NPF-94. 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 October 15, 2015 (80 FR 61476). 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 June 30, 2015. The exemption and amendment were issued on June 2, 2016, as part of a combined package to the licensee (ADAMS Accession No. ML16095A115).
