SUPPLEMENTARY INFORMATION:

I. Introduction

The NRC is granting an exemption from Tier 1 information in the certified DCD incorporated by reference in part 52 of title 10 of the Code of Federal Regulations (10 CFR), appendix D, “Design Certification Rule for the AP1000 Design,” and issuing License Amendment No. 45 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 change Tier 1 information. With the requested amendment, the licensee sought proposed changes related to the plant-specific Tier 1 tables related to the Class 1E DC and uninterruptible power supply system. The Tier 1 tables contain ITAAC and specifically, the licensee sought proposed changes to Tier 1 ITAAC Table 2.6.3-1 contains lists Category I equipment and Tier 1 ITAAC Table 2.6.3-4 contains component locations for this system. The proposed changes to plant-specific Tier 1 information also contain corresponding Start Printed Page 35068COL Appendix C and UFSAR Tier 2 information that would facilitate the replacement of four Class 1E DC and uninterruptible power supply system (IDS) spare termination boxes with a single spare battery termination box.

The granting of the exemption allows the changes to Tier 1 information requested 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.

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 10 CFR 52.63(b)(1). The license amendment was found to be acceptable as well. The combined safety evaluation is available in ADAMS under Accession No. ML16075A107.

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). These documents can be found in ADAMS under Accession Nos. ML16075A126 and ML16075A133, 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. ML16068A113 and ML16068A115, 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 VCSNS, Units 2 and 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 July 6, 2015, supplemented March 24, 2016, the South Carolina Electric & Gas Company acting on behalf of the South Carolina Public Service Authority (hereafter referred to as the licensees) requested from the Nuclear Regulatory Commission (NRC or Commission) an exemption to allow changes to Tier 1 information in the certified Design Control Document (DCD) incorporated by reference in Title 10 of the Code of Federal Regulations (10 CFR) part 52, appendix D, “Design Certification Rule for the AP1000 Design,” as part of license amendment request (LAR) 14-10, “Addition of Instruments to Design Reliability Assurance Program (D-RAP).”

For the reasons set forth in Section 3.1 of the NRC staff's Safety Evaluation that supports this license amendment, which can be found at Agencywide Documents Access and Management System (ADAMS) Accession No. ML16075A107, 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 licensees are granted an exemption from the certified AP1000 DCD Tier 1 information, as described in the licensee's request dated July 6, 2015, supplemented by letter dated March 24, 2016. This exemption is related to, and necessary for, the granting of License Amendment No. 45, which is being issued concurrently with this exemption.

3. As explained in Section 5.0 of the NRC staff's Safety Evaluation that supports this license amendment (ADAMS Accession No. ML16075A107), 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

The request for the amendment and exemption was submitted by the letter dated July 6, 2015. The licensee supplemented this request by the letter dated March 24, 2016. The proposed amendment is described in Section I, above.

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 September 1, 2015 (80 FR 52806). No comments were received during the 30-day comment period.

The NRC staff has found that the amendment involves no significant hazards consideration. The Commission has determined that these amendments satisfy the criteria for categorical exclusion in accordance with 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared for these amendments. The supplement dated March 24, 2016, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the staff's original proposed no significant hazards consideration determination as published in the Federal Register.

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 July 6, 2015, and supplemented by the letter dated March 24, 2016. The exemption and amendment were issued on May 2, 2016, as part of a combined package to the licensee (ADAMS Accession No. ML16095A290).
