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. 43 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.
    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. 
Specifically, the amendments allow the implementation of changes to the 
Class 1E dc and Uninterruptible Power Supply System (IDS), replacing 
four spare termination boxes with a single spare battery termination 
box and minor cable raceway and cable routing changes. The exemptions 
allow the implementation of changes to the plant-specific Tier 1 UFSAR 
that are different from those in the generic Tier 1 information in the 
AP1000 Certified Design Control Document.

[[Page 35386]]

    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 
inspection, test, analysis, and acceptance criteria (ITAAC) and 
specifically, the licensee sought proposed changes to Tier 1 ITAAC 
Table 2.6.3-1 that contains lists Category I equipment and Tier 1 ITAAC 
Table 2.6.3-4 that contains component locations for this system. The 
proposed changes to plant-specific Tier 1 information also contain 
corresponding COL 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.
    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. ML16068A149.
    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. ML16068A119 and ML16068A120, 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 ML16068A117, 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 December 19, 2014, supplemented February 25, 
2015, the South Carolina Electric & Gas Company (SC&G/licensee) 
requested from the Nuclear Regulatory Commission (NRC/Commission) an 
exemption from the provisions of Title 10 of the Code of Federal 
Regulations (10 CFR) Part 52, Appendix D, ``Design Certification Rule 
for AP1000 Design,'' Section VIII.B.6.b, Item (4), to allow a departure 
from the certified information as part of license amendment request 
(LAR) 13-29, ``Consolidation of Class 1E DC and Uninterruptible Power 
Supply System Spare Battery Termination Boxes.''
    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 
Number ML16068A149, 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 AP1000 DCD Tier 1 information, as described in the licensee's 
request dated December 19, 2014, supplemented February 25, 2015. This 
exemption is related to, and necessary for, the granting of License 
Amendment No. 43, which is being issued concurrently with this 
exemption.
    3. As explained in Section 5 of the NRC staff's Safety Evaluation 
that supports this license amendment (ADAMS Accession Number 
ML16068A149), 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 December 19, 2014. The licensee supplemented this request 
by the letter dated February 25, 2015. 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 May 12, 2015 (80 FR 27200). 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 February 25, 2015, 
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 December 19, 2014, and supplemented by the letter dated 
February 25, 2015. The exemption and amendment were issued on April 25, 
2016, as part of a combined package to the licensee (ADAMS Accession 
No. ML16077A120).

    Dated at Rockville, Maryland, this 24th day of May 2016.

    For the Nuclear Regulatory Commission.
