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 & Gas Company
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. 29 to Combined Licenses (COL), NPF-93 and NPF-94. The
COLs were issued to South Carolina Electric & Gas Company (SCE&G), and
South Carolina Public Service Authority (the licensee), for
construction and operation of the Virgil C. Summer Nuclear Station
(VCSNS),
[[Page 55382]]
Units 2 and 3 located in Fairfield County, South Carolina.
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.
DATES: September 15, 2015.

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. 29 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 related to the design
details of the containment internal structural wall modules (CA04,
CA01, and CB65). The proposed changes to Tier 2 information in the
VCSNS Units 2 and 3 Updated Final Safety Analysis Report (UFSAR),
plant-specific Tier 1 information, and corresponding COL appendix C
information would allow an increase of the concrete wall thickness
tolerances. The proposed changes would allow:
(1) A change to Tier 2 information in UFSAR Subsection 3.8.3.6.1,
``Fabrication, Erection, and Construction of Structural Modules,'' to
allow an increase in wall thickness tolerance beyond the American
Concrete Institute (ACI) 117, ``Standard Specifications for Tolerance
for Concrete Construction and Material,'' specified tolerance for some
ContainmentInternal Structure (CIS) walls;
(2) the addition of Notes 10 and 11 to Tier 1 Table 3.3-1, which
provides the wall thickness tolerance deviations.
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. ML15216A264.
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. ML15216A245 and ML15216A249, 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.
ML15216A075 and ML15216A183, 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 September 25, 2014, and supplemented by letter
dated March 13, 2015, South Carolina Electric & Gas Company (licensee)
requested from the Nuclear Regulatory Commission (Commission) an
exemption to allow departures from Tier 1 information in the certified
Design Control Document (DCD) incorporated by reference in 10 CFR part
52, appendix D, ``Design Certification Rule for the AP1000 Design,'' as
part of license amendment request (LAR) 14-07, ``CA04 Structural Module
Inspection, Test, Analysis, and Acceptance Criteria Dimensions
Change.''
For the reasons set forth in Section 3.1 of the NRC staff's Safety
Evaluation, which can be found at ADAMS Accession No. ML15216A264, 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 Table: 3.3-1, as described in the licensee's
request dated September 25, 2014, and supplemented by letter dated
March 13, 2015. This exemption is related to, and necessary for the
granting of License Amendment No. 29, which is being issued
concurrently with this exemption.
[[Page 55383]]
3. As explained in Section 5.0 of the NRC staff's Safety Evaluation
(ADAMS Accession No. ML15216A264), 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 September 25, 2014. The licensee supplemented this request
by the letter dated March 13, 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 April 14, 2015 (80 FR 20020). 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.
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 September 25, 2014, and supplemented by the letter dated
March 13, 2015. The exemption and amendment were issued on August 24,
2015, as part of a combined package to the licensee (ADAMS Accession
No. ML15216A071).
Dated at Rockville, Maryland, this 4th day of September 2015.
For the Nuclear Regulatory Commission.
Lawrence Burkhart,
Chief, Licensing Branch 4, Division of New Reactor Licensing, Office of
New Reactors.
