NUCLEAR REGULATORY COMMISSION
[Docket Nos. 52-027 and 52-028; NRC-2008-0441]
Virgil C. Summer Nuclear Station, Units 2 and 3; South Carolina
Electric and Gas; Change to the Bracing Design in the Turbine Building
and Corresponding Change to Structural Design Code
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 issuing License
Amendment No. 7 to Combined Licenses (COL), NPF-93 and NPF-94. The COLs
were issued to South Carolina Electric and Gas (SCE&G) and South
Carolina Public Service Authority (Santee Cooper) (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
amendment changes requested revise the design of the bracing used to
support the Turbine Building structure. This request requires changing
Tier 1 information found in the Design Description portion of Updated
Final Safety Analysis Report (UFSAR) section 3.3, ``Buildings.'' 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:
[[Page 48725]]
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. 7 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 to revise UFSAR
information related to the design of the bracing used to support the
non-seismic portion of the Turbine Building. As part of this request,
the licensee needed to change Tier 1 information located in the
``Design Description'' portion of section 3.3, ``Buildings'' of the
UFSAR. These changes sought to allow the licensee to use a mixed
bracing system of both eccentrically and concentrically braced framing
versus only eccentrically braced framing in the Turbine Building.
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. ML13151A472.
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. ML13151A466 and ML13151A468. 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. ML13151A461 and
ML13151A463. 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 February 7, 2013, and supplemented by a letter
dated February 14, 2013, the licensee requested from the Commission an
exemption from the provisions of 10 CFR Part 52, Appendix D, Section
III.B, ``Design Certification Rule for the AP1000 Design, Scope, and
Contents,'' as part of license amendment request 13-03, ``Turbine
Building Eccentric and Concentric Bracing.''
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. ML13151A472, 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 to the
provisions of 10 CFR Part 52, Appendix D, Section III.B, to allow
deviations from the Tier 1 certification information in the ``Design
Description'' portion of section 3.3 ``Buildings'' of the Certified
Design Control Document regarding the design of the supports used in
the non-seismic portion of the Turbine Building, as described in the
licensee's request dated February 7, 2013 and supplemented on February
14, 2013. This exemption is related to, and necessary for the granting
of License Amendment No. 7, which is being issued concurrently with
this exemption.
3. As explained in Section 5.0, ``Environmental Consideration,'' of
the NRC staff Safety Evaluation (ADAMS Accession No. ML13151A472), 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 July 1, 2013.
III. License Amendment Request
By letter dated February 7, 2012, the licensee requested that the
NRC amend the COLs for VCSNS Units 2 and 3, COLs NPF-93 and NPF-94. The
licensee supplemented this application on February 14, 2013. The
licensee sought to change Tier 2 information previously incorporated
into the UFSAR. Additionally, these Tier 2 changes involved changes to
Tier 1 material in the UFSAR, and would revise the associated material
that has been included in Appendix C of each of the VCS, Units 2 and 3,
COLs. The Tier 2 changes modified sections of the UFSAR related to the
design information and code requirements regarding the supports used in
the Turbine Building. These Tier 2 changes require modifications to
particular Tier 1 information located in the ``Design Description''
portion of Section 3.3. ``Buildings'' of the UFSAR. In this section the
licensee sought to revise the original design of only using
eccentrically braced framing in the non-seismic portion of the Turbine
Building. Instead the licensee plans to use a mixed bracing system
consisting of both eccentrically and concentrically braced framing. The
staff determined that these changes did not alter any relevant
conclusions made for the AP1000 standard design.
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 March 4, 2013 (78 FR 14126). The supplements had no effect
on the no significant hazards consideration determination and no
comments were received during the 60-day comment period.
The Commission has determined that these amendments satisfy the
criteria for categorical exclusion in accordance
[[Page 48726]]
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 February 7, 2013, and supplemented by letter dated
February 14, 2013. The exemption and amendment were issued on July 1,
2013 as part of a combined package to the licensee. (ADAMS Accession
No. ML13151A457).
Dated at Rockville, Maryland, this 5th day of August 2013.
