NUCLEAR REGULATORY COMMISSION

Federal Register Volume 82, Issue 83 (May 2, 2017)

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 AP1000 design control document (DCD) and is issuing License Amendment No. 62 to Combined Licenses (COL), NPF-93 and NPF-94. The COLs were issued to South Carolina Electric & Gas Company and the South Carolina Public Service Authority, (both collectively referred to as 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.

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

[[Page 20501]]

License Amendment No. 64 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,'' of appendix D, to 10 CFR part 52 to 
modify the design of the low capacity Central Chilled Water Subsystem 
(VWS) by relocating Air Cooled Chiller Pump 3 and its associated 
equipment, including a new chemical feed tank, from the Auxiliary 
Building to the Annex Building. The LAR consists of changes to the 
Updated Final Safety Analysis Report (UFSAR) in the form of departures 
from the incorporated generic AP1000 Design Control Document (DCD) Tier 
2 and Tier 2* information and changes to Tier 1 information, with 
corresponding changes to the associated COL Appendix C information.
    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, and 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. ML17031A116.
    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. ML17031A106 and 
ML17031A113, 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. ML17031A098 and 
ML17031A104, 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 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 October 21, 2015, as supplemented by letters 
dated March 31 and July 14, 2016, South Carolina Electric & Gas Company 
on behalf of itself and the South Carolina Public Service Authority 
(both hereafter called the licensee) requested from the Nuclear 
Regulatory Commission (NRC or Commission) an exemption to allow 
departures from 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) 13-31, ``Relocation of Air Cooled Chiller Pump 
3.''
    For the reasons set forth in Section 3.1 of the NRC staff's Safety 
Evaluation, which can be found at ADAMS Accession Number ML17031A116, 
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, with corresponding changes to 
Appendix C of the Facility Combined Licenses as described in the 
licensee's request dated October 21, 2015, as supplemented by letters 
dated March 31 and July 14, 2016. This exemption is related to, and 
necessary for, the granting of License Amendment No. 62, which is being 
issued concurrently with this exemption.
    3. As explained in Section 5.0 of the NRC staff's Safety Evaluation 
(ADAMS Accession Number ML17031A116), 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 October 21, 2015 (ADAMS Accession No. ML15295A090), 
supplemented by letters dated March 31 and July 14, 2016 (ADAMS 
Accession Nos. ML16091A380 and ML16196A354, respectively), 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 COL, 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 
January 19, 2016 (81 FR 2915). 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 March 1, 2017. The exemption and amendment were also 
issued on March 1, 2017, as part of a combined package to the licensee 
(ADAMS Accession No. ML17031A088).

    Dated at Rockville, Maryland, this 21st day of April 2017.

    For the Nuclear Regulatory Commission.
