NUCLEAR REGULATORY COMMISSION

10 CFR Part 52

RIN 3150-AI84
[NRC-2010-0134]


U.S. Advanced Boiling Water Reactor Aircraft Impact Design 
Certification Amendment

AGENCY: Nuclear Regulatory Commission.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or the Commission) 
proposes to amend its regulations to certify an amendment to the U.S. 
Advanced Boiling Water Reactor (ABWR) standard plant design to comply 
with the NRC's aircraft impact assessment (AIA) regulations. This 
action would allow applicants or licensees intending to construct and 
operate a U.S. ABWR to comply with the NRC's AIA regulations by 
referencing the amended design certification rule (DCR). The applicant 
for certification of the amendment to the U.S. ABWR design is STP 
Nuclear Operating Company (STPNOC). The public is invited to submit 
comments on this proposed DCR, the STPNOC design control document (DCD) 
that would be incorporated by reference into the DCR, and the 
environmental assessment (EA) for the amendment to the U.S. ABWR 
design. The public is also invited to submit comments on the NRC's 
proposed approach for treating multiple suppliers of a single certified 
design.

DATES: Submit comments on the DCR, DCD, and/or EA by April 5, 2011.

Comments on the Proposed Amendment to the U.S. ABWR Design 
Certification.''

II. Background

    Title 10 of the Code of Federal Regulations, (10 CFR) Part 52 
``Licenses, Certifications, and Approvals for Nuclear Power Plants,'' 
Subpart B, presents the process for obtaining standard design 
certifications. Section 52.63, ``Finality of standard design 
certifications,'' provides criteria for determining when the Commission 
may amend the certification information for a previously certified 
standard design in response to a request for amendment from any person. 
On June 30, 2009, STPNOC tendered its application with the NRC for 
amendment of the U.S. ABWR standard plant design certification to 
comply with the requirements of 10 CFR 50.150, ``Aircraft impact 
assessment'' (ADAMS Accession Number ML092040048). STPNOC submitted 
this application in accordance with 10 CFR 52.63. STPNOC proposed 
several changes to the certified U.S. ABWR design to comply with 10 CFR 
50.150, including the addition of an alternate feedwater injection 
system, the addition and upgrading of fire barriers and doors, and the 
strengthening of certain structural barriers. The NRC formally accepted 
the application as a docketed application for amendment to the U.S. 
ABWR design certification (Docket No. 52-001) on December 1, 2009 (74 
FR 62829).
    On June 12, 2009 (74 FR 28112), the NRC amended its regulations to 
require applicants for new nuclear power reactor designs to perform a 
design-specific assessment of the effects of the impact of a large, 
commercial aircraft (the AIA rule). These new provisions in 10 CFR 
50.150 require applicants to use

[[Page 3542]]

realistic analyses to identify and incorporate design features and 
functional capabilities to ensure, with reduced use of operator 
actions, that (1) the reactor core remains cooled or the containment 
remains intact, and (2) spent fuel cooling or spent fuel pool integrity 
is maintained. When it issued the AIA rule, the Commission stated that 
the requirements in existence at that time, in conjunction with the 
March 2009 revisions to 10 CFR 50.54 to address loss of large areas of 
the plant due to explosions or fires, would continue to provide 
adequate protection of the public health and safety and the common 
defense and security. Nevertheless, the Commission decided to also 
require applicants for new nuclear power reactors to incorporate into 
their design additional features to show that the facility can 
withstand the effects of an aircraft impact. The Commission stated that 
the AIA rule to address the capability of new nuclear power reactors 
relative to an aircraft impact is based both on enhanced public health 
and safety and enhanced common defense and security, but is not 
necessary for adequate protection. Rather, the AIA rule's goal is to 
enhance the facility's inherent robustness at the design stage.
    The AIA rule requirements apply to various categories of 
applicants, including applicants for combined licenses (COLs) that 
reference a standard design certification issued before the effective 
date of the AIA rule, which have not been amended to comply with the 
rule. These COL applicants have two methods by which they can comply 
with 10 CFR 50.150. They can request an amendment to the certified 
design or they can address the requirements of 10 CFR 50.150 directly 
in their COL application. STPNOC submitted an application for a COL on 
September 20, 2007. STPNOC has requested this amendment to the U.S. 
ABWR certified design to address the requirements of the AIA rule.

III. Discussion

A. Technical Evaluation of STPNOC Amendment to U.S. ABWR Design

    The NRC's review of the applicant's proposed amendment to the U.S. 
ABWR design certification confirmed that the applicant has complied 
with 10 CFR 50.150. Specifically, the staff confirmed that the 
applicant adequately described key AIA design features and functional 
capabilities in accordance with the AIA rule and conducted an 
assessment reasonably formulated to identify design features and 
functional capabilities to show, with reduced use of operator action, 
that the facility can withstand the effects of an aircraft impact. In 
addition, the staff determined that there will be no adverse impacts 
from complying with the requirements for consideration of aircraft 
impacts on conclusions reached by the NRC in its review of the original 
U.S. ABWR design certification. Finally, the staff determined that 
STPNOC and its contractors are technically qualified to perform the 
design work associated with the amended portion of the U.S. ABWR design 
represented by STPNOC's application and to supply the amended portion 
of the U.S. ABWR design. STPNOC's amendment to the U.S. ABWR design has 
achieved the Commission's objectives of enhanced public health and 
safety and enhanced common defense and security through improvement of 
the facility's inherent robustness at the design stage.

B. Regulatory and Policy Issues

Multiple Suppliers for a Single Certified Design
    In the 1989 10 CFR part 52 rulemaking, the Commission decided to 
approve standard reactor designs by rulemaking, as opposed to 
licensing, and stated that a design certification rule ``does not, 
strictly speaking, belong to the designer'' (54 FR 15327; April 18, 
1989, at 15375, third column). Nonetheless, the Commission implicitly 
recognized the need to protect the commercial and proprietary interests 
of the original applicant who intends to supply the certified design, 
should there be another entity who intends to use the design in some 
fashion without approval or compensation to the original design 
certification applicant. Id. The protection was provided, in part, 
through the decision of the Commission to protect ``proprietary 
information''\1\ developed by the original design certification 
applicant, as well as by several other regulatory provisions in both 10 
CFR part 52 and 10 CFR part 170.
---------------------------------------------------------------------------

    \1\ The term, ``proprietary information,'' means trade secrets 
or commercial or financial information that are privileged or 
confidential, as those terms are used under the Freedom of 
Information Act and the NRC's implementing regulation at 10 CFR part 
9.
---------------------------------------------------------------------------

    Based upon the licensing experience with operating nuclear power 
plants, the Commission understood that portions of proposed design 
certifications, primarily in the area of fuel design, would likely be 
regarded as proprietary information (trade secrets) by future design 
certification applicants. To ensure that design certification 
applicants would not be adversely affected in their capability to 
protect this proprietary information as a result of the NRC's decision 
to approve designs by rulemaking rather than licensing, the Commission 
adopted 10 CFR 52.51(c), which states, in relevant part:

    Notwithstanding anything in 10 CFR 2.390 to the contrary, 
proprietary information will be protected in the same manner and to 
the same extent as proprietary information submitted in connection 
with applications for licenses, provided that the design 
certification shall be published in Chapter I of this title.

10 CFR 52.51(c) (1990, as originally promulgated in the 1989 Part 52 
rulemaking, see 54 FR 15372; April 18, 1989, at 15390).\2\
---------------------------------------------------------------------------

    \2\ As originally adopted in 1989, 10 CFR 52.51(c) consisted of 
two sentences. The first sentence limited the bases for a decision 
in a hearing on a design certification to information on which all 
parties had an opportunity to comment; the second sentence is the 
language of the current regulation. The first sentence was removed 
in 2004 as a conforming change when the Commission removed the 
hearing requirements for design certification (69 FR 2182; January 
14, 2004).
---------------------------------------------------------------------------

    Having protected proprietary information developed by the design 
certification applicant, the Commission then adopted several additional 
rulemaking provisions in 10 CFR part 52 providing additional regulatory 
protection to the original design certification applicant against 
unfair use of the design certification by other suppliers. The 
Commission required the (original) design certification applicant, as 
well as the applicant for renewal of the design certification, to 
include in the application:

a level of design information sufficient to enable the Commission to 
judge the applicant's proposed means of assuring that construction 
conforms to the design and to reach a final conclusion on all safety 
questions associated with the design before the certification is 
granted. The information submitted for a design certification must 
include performance requirements and design information sufficiently 
detailed to permit the preparation of acceptance and inspection 
requirements by the NRC, and procurement specifications and 
construction and installation specifications by an applicant.

10 CFR 52.47(a)(2) (1990, as originally promulgated in the 1989 Part 52 
rulemaking, see 54 FR 15372; April 18, 1989; at 15390);\3\ 10 CFR 
52.57(a).
---------------------------------------------------------------------------

    \3\ This language was moved to the introductory paragraph of the 
current 10 CFR 52.47 in the 2007 revision of 10 CFR part 52.
---------------------------------------------------------------------------

    The Commission also adopted 10 CFR 52.63(c), requiring the 
applicant referencing the design certification to provide the 
information required to be developed by 10 CFR 52.47(a)(2) or its 
equivalent:


[[Page 3543]]


    The Commission will require, before granting a construction 
permit, combined license, operating license, or manufacturing 
license which references a design certification rule, that 
information normally contained in certain procurement specifications 
and construction and installation specifications be completed and 
available for audit if the information is necessary for the 
Commission to make its safety determinations, including the 
determination that the application is consistent with the 
certification information. This information may be acquired by 
appropriate arrangements with the design certification applicant.

10 CFR 52.63(c) (1990). By requiring a level of detailed information 
supporting the certified design to be developed and available for NRC 
audit at renewal and when the design was referenced for use, the 
Commission ensured (among other things) that entities who were not the 
original design certification applicant would not have an inordinate 
financial advantage when either supplying the certified design to a 
referencing user, or referencing the certified design in an 
application.
    The Commission also relied on its statutory authority to make a 
technical qualifications finding under Section 182 of the Atomic Energy 
Act of 1954 (AEA) as amended, to adopt 10 CFR 52.73, which effectively 
prohibits a COL applicant from referencing a certified design unless 
the entity that actually supplies the design to the referencing 
applicant is technically qualified to supply the certified design:

    In the absence of a demonstration that an entity other than the 
one originally sponsoring and obtaining a design certification is 
qualified to supply such design, the Commission will entertain an 
application for a combined license which references a standard 
design certification issued under Subpart B only if the entity that 
sponsored and obtained the certification supplies the certified 
design for the applicant's use.

10 CFR 52.73 (1990, as originally promulgated in the 1989 Part 52 
rulemaking, see 54 FR 15372; April 18, 1989, at 15393).\4\
---------------------------------------------------------------------------

    \4\ This provision was slightly reworded in the 2007 rulemaking 
amending 10 CFR part 52 in a newly-designated paragraph (b) to 10 
CFR 52.73 (72 FR 49352; August 28, 2007).
---------------------------------------------------------------------------

    Apart from the provisions discussed previously, the Commission also 
indicated in the statements of consideration for the 1989 10 CFR part 
52 rulemaking that the finality provisions in 10 CFR 52.63 provided 
some protection against arbitrary amendment or rescission of the design 
certification. Any proposed rescission or amendment of the design 
certification must be accomplished under notice and comment rulemaking 
procedures, as required by 10 CFR 52.63(a)(1). The original applicant 
would, accordingly, have the opportunity to comment on any proposed 
change to the design, including those changes initiated by other 
entities.
    Finally, the Commission adopted, as part of the 1989 rulemaking, 
conforming amendments to 10 CFR 170.12(d) and (e). Under these 
provisions, entities other than the original design certification 
applicant who provide either the renewed or original certified design 
to a referencing applicant for a construction permit, operating license 
or COL must pay the applicable installment of the deferred NRC fee \5\ 
for review of the original or renewed design certification.
---------------------------------------------------------------------------

    \5\ In the 1989 final 10 CFR part 52 rulemaking, the Commission 
decided that the payment of the fee imposed upon the design 
certification applicant to recover the NRC's costs for review and 
approval of the certified design via rulemaking, and renewal of the 
design certification rule, should be deferred and recovered in equal 
increments the first five times the DCR was referenced in an 
application. See 10 CFR 107.12(d)(2) (renewal of DCR); 10 CFR 
170.12(e)(2)(i) (initial certification) (1990), as originally 
promulgated in the 1989 10 CFR part 52 rulemaking (see 54 FR 15372; 
April 18, 1989, at 15399).
---------------------------------------------------------------------------

    After the 1989 rulemaking, in each of the four existing DCRs in 10 
CFR part 52, Appendices A through D, the Commission adopted an 
additional provision serving to protect the proprietary information and 
SGI developed by the original design certification applicant. Paragraph 
IV.A.3 of each rule required an applicant referencing the DCR to 
``physically include in the plant-specific DCD proprietary information 
and safeguards information referenced in the DCD.'' The Commission's 
view was that by ``physically'' including the proprietary information 
and SGI developed by the original DCR applicant in the application, 
this would be demonstrative of the referencing applicant's rights to 
use that information; otherwise, the referencing applicant could 
provide the equivalent information (62 FR 25800; May 12, 1997, at 
25818, third column). In 2007, at the request of NEI and other industry 
commenters, the word, ``physically'' was removed from Paragraph IV of 
each of the four DCRs, to allow the DCR applicant more flexibility in 
how the proprietary information and SGI are included in the application 
referencing the DCR (72 FR 49352; August 28, 2007, at 49363-49365). 
This change was not intended to represent a retreat from the 
Commission's position that the referencing applicant has the 
appropriate commercial rights to reference the proprietary and SGI 
information or its equivalent. However, the NRC acknowledges that under 
the current language of paragraph IV.A.3., the NRC must do more to 
verify that the referencing applicant has the appropriate commercial 
rights to the proprietary and SGI information developed by the 
originating applicant (unless, of course, the referencing applicant 
indicates that it is supplying ``equivalent'' information).
    The Commission did not describe in the 1989 rulemaking the 
particular regulatory approach and structure to be used for a design 
certification rule with two or more suppliers of the certified design. 
In the years after the 1989 Part 52 rulemaking, the Commission did not 
need to address the circumstance of multiple suppliers of the same 
certified design (multiple suppliers) to an end user.\6\ However, with 
the filing of the U.S. ABWR design certification amendment request by 
STPNOC, as well as Toshiba's March 3, 2010, letter to the NRC stating 
that it intends to seek renewal of the U.S. ABWR design certification 
(ADAMS Accession No. ML100710026), the NRC must now determine the 
regulatory approach and structure for the amendment (and, for 
completeness, the renewal) of a certified design where there will be 
multiple suppliers.
---------------------------------------------------------------------------

    \6\ The term, ``user,'' means an entity which references the 
standard design certification rule in its application, and the 
holder of a permit or license which incorporates the standard design 
certification.
---------------------------------------------------------------------------

    When the NRC was advised of STPNOC's intent to submit an amendment 
of the U.S. ABWR design certification, it began a process of 
identifying and considering possible regulatory alternatives, with the 
goal of identifying a single regulatory approach and structure to be 
used for all design certifications with multiple suppliers. The NRC 
considered three alternatives which it could reasonably select:
    1. Separate rules: Develop separate design certification rules for 
each supplier.
    2. Branches: Develop one design certification rule with multiple 
branches, with each branch describing a complete design to be supplied 
by each supplier.
    3. Options: Develop one design certification rule with options, 
with each option describing a portion of the certified design which may 
be selected by the user as an option to the original ``reference'' 
certified design.
    Table 1 presents the NRC's current views with respect to the 
differences between these three alternatives.

[[Page 3544]]

    In light of the Commission's past practice of protecting the 
proprietary information and legitimate commercial interests of the 
original design certification applicant wherever consistent with other 
applicable law, the NRC believes that it should consider that practice 
when evaluating possible alternatives for the approach and structure of 
a design certification rule with multiple suppliers. Upon 
consideration, the NRC concludes that the ``branches'' alternative 
should be adopted as the general approach for all renewals of design 
certifications and for major design certification amendments. The 
``branches'' alternative: (1) Is consistent with all applicable law; 
(2) protects the proprietary information and legitimate commercial 
interests of the original design certification applicant (as well as 
the additional suppliers); and (3) meets the NRC's regulatory concerns. 
Each of these considerations is discussed separately below.

No Statutory or Other Legal Prohibition to the ``Branches'' Alternative

    There is no statutory or other legal prohibition, explicit or 
otherwise, against use of the ``branches'' alternative in the AEA, the 
Administrative Procedure Act, the National Technology Transfer and 
Advancement Act, or other statutes applicable to the NRC. Design 
certification rulemaking is not specifically addressed in the AEA. The 
AEA provisions do not appear to circumscribe or prohibit the NRC's use 
of a regulatory approach of approving multiple suppliers of a set of 
closely related certified designs in a single codified rule. Moreover, 
nothing in Part 52 compels the use of a particular alternative for 
addressing multiple suppliers. As discussed previously, the Commission 
contemplated that multiple suppliers could supply the same certified 
design from the time it first adopted the concept of design 
certification by rulemaking. However, the Commission did not mandate 
any specific regulatory approach for accommodating multiple suppliers 
of a certified design. Those provisions intended to protect proprietary 
information and the commercial interests of each supplier do not 
mandate any specific approach for accommodating multiple suppliers, and 
do not foreclose the use of the ``branches'' alternative.

Protection of Proprietary Information and Legitimate Commercial 
Interests of All Suppliers

    The ``branches'' alternative fully protects the proprietary 
information and legitimate commercial interests of all suppliers. Under 
the ``branches'' alternative, each supplier is responsible for creating 
and maintaining its own DCD (including the non-public version of the 
DCD containing SUNSI (including proprietary information) and SGI 
developed by the supplier). Because each DCD is self-contained, the NRC 
does not foresee any circumstance that would require the NRC to provide 
the non-public DCD (or information supporting its DCD) prepared and 
supported by the original design certification applicant to the new 
supplier, or to provide the non-public DCD prepared and supported by 
the new supplier to the original applicant. Nor does the use of the 
``branches'' alternative affect the legal issues associated with 
providing access to SUNSI (including proprietary information) and SGI 
to members of the public to facilitate public comment on a proposed 
design certification rulemaking adding a new supplier and branch.
    The ``branches'' alternative has no effect on the legal 
applicability, or on the NRC's implementation of the 10 CFR part 52 and 
part 170 provisions discussed previously, which are directed at 
protecting the proprietary information and commercial interests of the 
original design applicant. These provisions, properly applied, should 
also protect the proprietary information and interests of all other 
suppliers of a subsequently-approved ``branch.'' Thus, the ``branches'' 
alternative affords all suppliers all of the protection of their 
proprietary information and commercial interests, which the Commission 
intended to be provided to these suppliers.
    A rulemaking adopting a new ``branch'' (a `` `branch' rulemaking'') 
would not disturb the issue resolution and finality accorded to the 
original certified design (as amended in any subsequent rulemakings), 
or to the certified design of any other suppliers in any previously 
approved branches. Nor would a ``branch'' rulemaking necessarily 
require the Commission to consider and address, in the final rulemaking 
adding the new ``branch,'' comments on the existing certified design. 
The NRC believes that each ``branch'' rulemaking is limited to adding 
the new ``branch'' together with requirements and conditions specific 
to the new ``branch.'' Therefore, the NRC asserts that: (1) The nuclear 
safety and other associated matters (severe accident mitigation design 
alternatives (SAMDAs)) resolved in the preceding design certification 
rulemaking(s) continue to be effective and are not being re-examined in 
the ``branch'' rulemaking; and (2) comments on the existing certified 
design(s) are out-of-scope and should not be considered in the 
``branch'' rulemaking.\7\
---------------------------------------------------------------------------

    \7\ If the out-of-scope comment seeking to modify the existing 
certified design was submitted by the original sponsor of that 
design, then the NRC believes that the original sponsor should seek 
an amendment of its certified design in accordance with the design 
certification amendment process as addressed in 10 CFR 52.57 and 
52.59, and 10 CFR 2.800(c) and 10 CFR 2.811 through 2.819 (as well 
as the procedures common to all petitions for rulemaking in 10 CFR 
2.804 through 2.810, as prescribed in 10 CFR 2.800(b)). By contrast, 
if the out-of-scope comment seeking to modify the existing certified 
design was submitted by any other entity (e.g., an entity that is 
not the supplier of that certified design branch), then the staff 
believes that these comments should be regarded as petitions for 
rulemaking and processed in accordance with the provisions of 10 CFR 
2.800(c) and 10 CFR 2.802 through 2.803 (as well as the procedures 
common to all petitions for rulemaking in 10 CFR 2.804 through 
2.810, as prescribed in 10 CFR 2.800(b)).
---------------------------------------------------------------------------

    The ``branches'' alternative would not require the original 
supplier (or indeed any previously-approved supplier) of the certified 
design to modify their DCD, or incur other costs as part of the 
``branch'' rulemaking. Hence, there is no financial impact upon the 
pre-existing suppliers. The NRC has not identified any credible 
argument that could be raised by the original design certification 
applicant that an NRC decision allowing a new supplier to supply the 
certified design could be the proximate cause of any diminution in the 
commercial value of the original applicant's certified design. The 
concept of multiple suppliers of a single certified design is inherent 
in the concept of design certification by rulemaking. The Commission 
anticipated multiple suppliers of a single design certification when it 
was considering the regulatory approach for certification (rulemaking 
versus licensing), and afforded protection to the original applicant by 
various provisions of 10 CFR part 52. This protection was embodied in 
provisions included in each of the design certification rules issued to 
date, and these provisions would continue to be included in future 
design certification rules. Hence, no supplier--including the original 
design certification applicant--may reasonably claim that the approval 
of a new ``branch'' constitutes an unwarranted diminution in the 
commercial value of the certified design which it sponsored.

NRC's Regulatory Concerns Are Met

    The NRC believes that any alternative and structure for a design 
certification rule with multiple suppliers must meet the following 
regulatory concerns. Any rule amendment (or renewal) which introduces a 
new supplier must

[[Page 3545]]

minimize the possibility of re-opening the safety and regulatory 
conclusions reached by the NRC with respect to previously approved 
aspects of the design and supplier(s). In addition, if the new supplier 
is proposing changes to the actual certified design, then the 
substitute or new portions of the design \8\ must, to the maximum 
extent practical, be attributable solely to the ``sponsoring'' 
supplier, and therefore distinguishable from the ``common'' portions of 
the design which each supplier must support (the ``branches'' 
alternative adopting the premise that the supplier must be technically 
qualified to supply all of the certified design, including the 
``common'' portions).\9\ The regulatory approach and structure must 
reflect a sound basis for allowing the NRC to make a technical 
qualifications finding with respect to the supplier. Finally, the 
approach and structure must allow for imposition of applicable NRC 
requirements on each supplier, and the legal ability of the NRC to 
undertake enforcement and regulatory action on each supplier.
---------------------------------------------------------------------------

    \8\ A ``substitute'' portion of the certified design sponsored 
by the new supplier serves to replace a discrete portion of a design 
as sponsored by the original design certification applicant (in 
other words, the basis for comparison of a new branch must always be 
the original certified design), but without augmenting or adding a 
completely new functional capability. By contrast, a ``new'' portion 
of the certified design sponsored by the new supplier serves to 
either: (1) Augment a discrete portion of the design as sponsored by 
the original design certification applicant; or (2) add a completely 
new functional capability not previously considered and addressed in 
the original certified design. As an example, the amendment of the 
ABWR DCR sought by STPNOC would add new functional capabilities--the 
ability to withstand aircraft impacts of the kind described in the 
AIA rule, 10 CFR 50.150. Hence, the ``changes'' sought by STPNOC 
would be considered ``new'' portions of the certified design.
    \9\ The NRC believes a broad finding of technical qualifications 
is necessary because the original design certification applicant is 
under no legal or NRC regulatory obligation (consistent with the 
concept of providing protection to the proprietary information and 
legitimate commercial interests of the original supplier) to provide 
technical support on the ``common'' portions of the certified design 
to either the new supplier or a user.
---------------------------------------------------------------------------

    The ``branches'' alternative meets all of these regulatory 
concerns. By creating a separate branch for the design to be supplied 
by the new supplier in the rule and requiring the new certified design 
to be described in a separate DCD created and supported by the new 
supplier, there is a strong basis for arguing that the certified 
design(s) already approved by the NRC are not affected and that the 
issue finality accorded to those certified designs (as controlled by 10 
CFR 52.63) continues. Hence, in any rulemaking approving a new branch, 
the NRC need not consider any comments seeking changes to the existing 
certified design.
    The use of a separate DCD to describe the new certified design, by 
its very nature, serves to distinguish any substitute or new portions 
of the certified design sponsored only by the new supplier, and make 
clear that the substitute or new portions are being sponsored solely by 
the new supplier (because the other branches do not contain any 
reference to or mention of the substitute or new portions of the design 
sponsored by the new supplier). The use of a separate DCD describing 
the entire design is also consistent with the NRC's position that it 
must conduct a technical qualifications review of the new supplier, and 
make a finding that the new supplier is technically qualified to 
provide the entire certified design. The NRC's recommendation to use a 
separate DCD, coupled with a structure of the design certification rule 
language (as codified in one of the appendices to 10 CFR part 52) that 
applies common regulatory requirements to all suppliers, allows for the 
NRC to take regulatory action against any supplier without regard to 
whether the supplier was the original design certification applicant.
    For these reasons, the NRC concluded that its regulatory concerns 
are met under the ``branches'' alternative. However, during discussions 
with STPNOC about the processing of its request to amend the U.S. ABWR 
design certification, STPNOC proposed that the NRC adopt a process 
similar to the ``options'' approach for the STPNOC U.S. ABWR amendment. 
The STPNOC request was based upon a number of factors which the NRC 
considered to be unique to STPNOC's situation. First, under the 
``branches'' approach, STPNOC would have to supply the U.S. ABWR 
proprietary information (or its equivalent) which was originally 
developed by GE Nuclear Energy (GE) and approved by the NRC in the 
original U.S. ABWR design certification rulemaking. While STPNOC has 
contractual rights from GE Hitachi Nuclear Energy (GEH) to use the GE-
developed U.S. ABWR proprietary information for South Texas Project 
(STP) Units 3 & 4, it does not have the right to supply the GE-
developed U.S. ABWR proprietary information to other companies in 
connection with any other application for a COL that references the 
certified U.S. ABWR. In addition, neither STPNOC nor its contractors 
would be in a position to provide complete information to substitute 
for the GE-developed U.S. ABWR proprietary information in time to 
support the schedule for issuance of the COLs for STP Units 3 & 4, 
should they be approved by the NRC. Second, STPNOC indicated that some 
portion of the GE-developed U.S. ABWR proprietary information relates 
to fuel design, and STPNOC does not intend to use the GE fuel design 
for initial operation of STP Units 3 & 4. Rather, STPNOC intends to use 
another fuel design and obtain NRC approval via an application for a 
COL amendment (i.e., after the issuance of the COLs). The GE-developed 
fuel design also would not be used to operate any of the possible six 
U.S. ABWRs that could be developed under the agreement between Toshiba 
and Nuclear Innovation North America LLC, which has the right to 
develop four U.S. ABWRs in addition to STP Units 3 & 4. Finally, STPNOC 
indicated that the ``options'' approach would not be used at renewal; 
the renewal application Toshiba was developing would reflect the use of 
the ``branches'' alternative (i.e., Toshiba would be seeking approval 
of and supplying the entire U.S. ABWR design at renewal, including 
replacement proprietary information). Based on these factors, STPNOC 
requested that it be considered the supplier for only that portion of 
the U.S. ABWR design certification necessary to comply with the AIA, 
and which is the subject of its amendment request.
    Upon consideration, the NRC is proposing to use the ``options'' 
approach for the STPNOC amendment of the U.S. ABWR design 
certification, based on the following considerations. As with the 
``branches'' alternative, there is no statute or NRC regulation 
prohibiting the use of the ``options'' approach. Nor is there any 
provision which prohibits the concurrent use of both alternatives--so 
long as the NRC is able to articulate a basis for doing so. Moreover, 
all of the NRC's safety and regulatory objectives are met. STPNOC is 
providing sufficient information to determine its technical 
qualifications\10\ to supply the STPNOC-sponsored amendments addressing 
the AIA rule to third party users (i.e., users other than STPNOC 
itself). In addition, the NRC believes that there are no

[[Page 3546]]

insurmountable issues in requiring the user (in most cases, the COL 
applicant referencing the U.S. ABWR and the STPNOC option) to prepare a 
single DCD integrating information from both the DCD developed by GE 
and the DCD developed by STPNOC. The ``options'' approach also avoids 
or addresses all of STPNOC's concerns with the use of the ``branches'' 
alternative for its request to amend the U.S. ABWR. STPNOC would not 
have to develop and submit to the NRC information equivalent to the 
proprietary information developed by GE to support the STPNOC amendment 
application. Nor does STPNOC have to demonstrate its technical 
qualifications to supply the entire U.S. ABWR certified design; it 
would only have to demonstrate its technical qualifications to supply 
the STPNOC option. Toshiba will prepare an application for renewal of 
the U.S. ABWR design certification (with Toshiba being the renewal 
applicant) that reflects the ``branches'' approach, and that 
application is likely to be submitted within the next year. Thus, the 
STPNOC option would have a limited period of effectiveness, that is, 
until the renewal of the U.S. ABWR design certification. Finally, the 
``options'' approach fully protects the legitimate proprietary and 
commercial interests of GE in the original U.S. ABWR design 
certification.
---------------------------------------------------------------------------

    \10\ The NRC staff determined that STPNOC and its contractors 
are technically qualified to perform the design work associated with 
the amended portion of the ABWR design represented by STPNOC's 
application and to supply the amended portion of the ABWR design. 
However, the NRC staff determined that STPNOC, by itself, is not 
technically qualified to supply the amended portion of the ABWR 
design certification represented in STPNOC's DCD, Revision 1. The 
NRC is proposing a provision in the amended ABWR DCR to specify that 
if a COL applicant references the STPNOC option but does not show 
they are obtaining the design from STPNOC and Toshiba American 
Nuclear Energy (TANE), acting together, then the COL applicant must 
demonstrate that the entity supplying the STPNOC option to the 
applicant possesses the technical qualifications to do so.
---------------------------------------------------------------------------

    Based on these considerations, the NRC is proposing to adopt the 
``options'' alternative for the STPNOC amendment of the U.S. ABWR 
design certification, but will regard the ``branches'' alternative as 
the default for all renewals of design certifications and for major 
design certification amendments. Under the ``options'' approach, 
applicants seeking amendments to already certified designs must be 
found to be qualified to supply the limited scope of the revisions they 
seek. If the NRC receives other limited-scope design certification 
amendments (similar in scope to the STPNOC amendment request), it will 
consider whether the ``branches'' approach or the ``options'' approach 
offers the most effective and efficient regulatory option at that time 
based on the scope of the amendment and the specific circumstances 
associated with the particular application.
    By implementing the ``options'' approach for the STPNOC U.S. ABWR 
amendment, a COL applicant that references the U.S. ABWR standard 
design certification can meet the requirements of the AIA rule by 
referencing both the GE DCD and the STPNOC DCD or by referencing only 
the GE DCD and addressing the requirements of the AIA rule separately 
in its COL application.

Notes:
1. If there is only a single description in a table cell, then that means that the description applies to all
  suppliers.
2. For purposes of this table, ``supplier'' means an entity that: (1) Submits an application for a new design
  certification, an amendment to an existing design certification, or a renewal for a design certification; and
  (2) intends to, has offered, or is providing design and engineering services related to the certified design
  to a license applicant. The information in this table does not apply to petitions for rulemaking under 10 CFR
  2.802 submitted by entities who are not acting, do not intend to act, or the NRC believes are not reasonably
  capable of acting as a ``supplier.'' ``Original supplier'' means the supplier who was the original applicant
  for the design certification.

C. Changes to Appendix A to Part 52--Design Certification Rule for the 
U.S. Advanced Boiling Water Reactor

1. Introduction (Section I)
    The NRC proposes to amend Section I, ``Introduction,'' to identify 
STPNOC as the applicant for the amendment of the U.S. ABWR design 
certification rule to address the AIA rule, 10 CFR 50.150. The portion 
of the certified design sponsored by STPNOC in this amendment, and 
which this rulemaking finds STPNOC (acting together with TANE) is 
technically qualified to supply, is termed the ``STPNOC certified 
design option'' or ``STPNOC option.'' As discussed in greater detail in 
the section-by-section analysis for Section III, ``Scope and 
Contents,'' an applicant or licensee referencing this appendix may use 
the GE certified design (which was first certified by the NRC in a 1997 
rulemaking (62 FR 25800; May 12, 1997)), or both the GE certified 
design together with the STPNOC option (the GE/STPNOC composite 
certified design).
    The overall purpose of paragraph I of this appendix is to identify 
the standard plant design that was approved and the applicant for 
certification of the standard design. Identification of both the 
original design certification applicant and the applicant for any 
amendment to the design is necessary to implement this appendix, for 
two reasons. First, the implementation of 10 CFR 52.63(c) depends on 
whether an applicant for a COL contracts with the design certification 
applicant to provide the generic DCD and supporting design information. 
If the COL applicant does not use the design certification applicant to 
provide the design information and instead uses an alternate nuclear 
plant supplier, then the COL applicant must meet the requirements in 
paragraph IV.A.4 of this appendix and 10 CFR 52.73. The COL applicant 
must demonstrate that the alternate supplier is qualified to provide 
the standard plant design information.
    By identifying STPNOC as the applicant for the amendment of the 
U.S. ABWR design certification rule, the provisions of 10 CFR 52.63 
will be given effect whenever a COL applicant references the certified 
design option sponsored by STPNOC, but does not use STPNOC to supply 
the design information for this option and instead uses an alternate 
supplier. In this circumstance, the COL applicant must meet the 
requirements in paragraph IV.A.4 of this appendix and 10 CFR 52.73 with 
respect to the STPNOC option (i.e., the COL applicant must demonstrate 
that the alternate supplier is qualified to provide the certified 
design information constituting the STPNOC option).
    In addition, by identifying STPNOC as the applicant, STPNOC must 
maintain the generic DCD for the STPNOC option throughout the time this 
appendix may be referenced by a COL, as required by paragraph X.A.1 of 
this appendix.
2. Definitions (Section II)
    The NRC is proposing to revise the definition of ``generic design 
control document (generic DCD)'' in paragraph A in Section II, 
``Definitions,'' to indicate that there will now be two generic DCDs 
incorporated by reference into this appendix--the DCD for the original 
U.S. ABWR design certification submitted by GE Nuclear Energy (GE DCD) 
and the DCD for the amendment to the U.S. ABWR design submitted by 
STPNOC (STPNOC DCD). The NRC is proposing this change to the definition 
of ``generic DCD'' to make it clear that all requirements in this 
appendix related to

[[Page 3551]]

the ``generic DCD'' apply to both the GE DCD and the STPNOC DCD, unless 
otherwise specified.
    During development of the first two DCRs, the Commission decided 
that there would be both generic (master) DCDs maintained by the NRC 
and the design certification applicant, as well as individual plant-
specific DCDs maintained by each applicant and licensee that reference 
this appendix. This distinction is necessary to specify the relevant 
plant-specific requirements to applicants and licensees referencing the 
appendix. To facilitate the maintenance of the master DCDs, the NRC 
proposes that each application for a standard design certification or 
amendment to a standard design certification be updated to include an 
electronic copy of the final version of the DCD. The final version 
would be required to incorporate all amendments to the DCD submitted 
since the original application as well as any changes directed by the 
NRC as a result of its review of the original DCD or as a result of 
public comments. This final version would become the master DCD 
incorporated by reference in the DCR. The master DCD would be revised 
as needed to include generic changes to the version of the DCD approved 
in this design certification rulemaking. These changes would occur as 
the result of generic rulemaking by the Commission, under the change 
criteria in Section VIII.
    The NRC proposes to incorporate by reference a second DCD into 
Appendix A of 10 CFR part 52, i.e., the DCD for the STPNOC option 
(STPNOC DCD). Under the proposed rule, a reference to a ``generic DCD'' 
means, in context, either or both: (i) The DCD for the original U.S. 
ABWR design certification submitted by GE (GE DCD); and (ii) the STPNOC 
DCD submitted by STPNOC.
3. Scope and Contents (Section III)
    The purpose of Section III is to describe and define the scope and 
contents of this design certification and to present how documentation 
discrepancies or inconsistencies are to be resolved. Paragraph III.A is 
the required statement of the Office of the Federal Register (OFR) for 
approval of the incorporation by reference of Tier 1, Tier 2, and the 
generic technical specifications into this appendix. The NRC is 
proposing to redesignate the existing paragraph A regarding the GE DCD 
as paragraph A.1 and to add a new paragraph A.2 indicating that the 
STPNOC DCD is also approved for incorporation by reference.
    The legal effect of incorporation by reference is that the 
incorporated material has the same legal status as if it were published 
in the Code of Federal Regulations. This material, like any other 
properly issued regulation, has the force and effect of law. The STPNOC 
DCD was prepared to meet the technical information contents of 
application requirements for design certifications under 10 CFR 
52.47(a) and the requirements of the OFR for incorporation by reference 
under 1 CFR part 51. One of the requirements of the OFR for 
incorporation by reference is that the applicant for the design 
certification (or amendment to the design certification) must make the 
generic DCD available upon request after the final rule becomes 
effective. Therefore, paragraph III.A.2 would identify a STPNOC 
representative to be contacted to obtain a copy of the STPNOC DCD.
    The generic DCD (master copy) for the STPNOC DCD is electronically 
accessible in ADAMS (Accession No. ML102870017); at the OFR; and at 
www.regulations.gov by searching under Docket ID NRC-2010-0134. Copies 
of the generic DCD would also be available at the NRC's PDR. Questions 
concerning the accuracy of information in an application that 
references this appendix will be resolved by checking the master copy 
of the generic DCD in ADAMS. If the design certification amendment 
applicant makes a generic change (through NRC rulemaking) to the DCD 
under 10 CFR 52.63 and the change process provided in Section VIII, 
then at the completion of the rulemaking the NRC would request approval 
of the Director, OFR, for the revised master DCD. The NRC would require 
that the design certification amendment applicant maintain an up-to-
date copy of the master DCD under paragraph X.A.1 that includes any 
generic changes it has made because it is likely that most applicants 
intending to reference the standard design would obtain the generic DCD 
from the design certification amendment applicant.
    In addition, the NRC is proposing to revise paragraph III.B to add 
text indicating that an applicant or licensee referencing this appendix 
may reference either the GE DCD, or both the GE DCD and the STPNOC DCD. 
An applicant referencing this appendix would be required to indicate in 
its application and in all necessary supporting documentation which of 
these two alternatives it is implementing. This information is 
necessary to support the NRC's review and processing of the license 
application. A COL applicant that does not reference both the GE DCD 
and the STPNOC DCD will be required, in accordance with 10 CFR 
50.150(a)(3)(v)(B) to comply with the requirements of 10 CFR 50.150 as 
part of its COL application.
    Paragraphs III.C and III.D set forth the way potential conflicts 
are to be resolved. Paragraph III.C would establish the Tier 1 
description in the DCD as controlling in the event of an inconsistency 
between the Tier 1 and Tier 2 information in the DCD. The NRC is 
proposing a minor change to paragraph III.C, which currently states 
that, if there is a conflict between Tier 1 and Tier 2 of the DCD, then 
Tier 1 controls. The revised paragraph would state that, if there is a 
conflict between Tier 1 and Tier 2 of a DCD, then Tier 1 controls. This 
change is necessary to indicate that this requirement applies to both 
the GE DCD and the STPNOC DCD.
    The NRC is also proposing a change to paragraph III.D. Paragraph 
III.D establishes the generic DCD as the controlling document in the 
event of an inconsistency between the DCD and the Final Safety 
Evaluation Report (FSER) for the certified standard design. The 
proposed revision would indicate that this is also the case for an 
inconsistency between the STPNOC DCD and the NRC's associated FSER, 
referred to as the ``AIA FSER.''
    The NRC is proposing to redesignate current paragraph III.E as 
proposed paragraph III.F and to add a new paragraph, III.E. Proposed 
paragraph III.E would state that, if there is a conflict between the 
design as described in the GE DCD and a design matter which implements 
the STPNOC certified design option but is not specifically described in 
the STPNOC DCD, then the GE DCD controls. This paragraph, which would 
be effective only with respect to the GE/STPNOC composite certified 
design, addresses the situation when, despite the best efforts of 
STPNOC and the NRC, there are unintended consequences or unaddressed 
issues resulting from STPNOC's amendment to the U.S. ABWR design. The 
NRC would expect the applicant or licensee discovering such issues to 
notify the NRC and STPNOC so that the issue could be addressed 
generically (if not reportable under existing NRC requirements such as 
10 CFR part 21, 10 CFR 52.6, 10 CFR 50.72 and 10 CFR 50.73).
4. Additional Requirements and Restrictions (Section IV)
    Section IV presents additional requirements and restrictions 
imposed upon an applicant who references this appendix. Paragraph IV.A 
presents the information requirements for these applicants. Paragraph 
IV.A.3 currently requires the applicant to include, not

[[Page 3552]]

simply reference, the proprietary and SGI referenced in the U.S. ABWR 
DCD, or its equivalent, to ensure that the applicant has actual notice 
of these requirements. The NRC is proposing to revise paragraph IV.A.3 
to indicate that a COL applicant must include, in the plant-specific 
DCD, the proprietary information and SGI referenced in both the GE DCD 
and the STPNOC DCD, as applicable.
    The NRC is also proposing to add a new paragraph IV.A.4 to indicate 
requirements that must be met in cases where the COL applicant is not 
using the entity that was the original applicant for the design 
certification (or amendment) to supply the design for the applicant's 
use. Proposed paragraph IV.A.4.a would require that a COL applicant 
referencing this appendix include, as part of its application, a 
demonstration that an entity other than GE Nuclear Energy is qualified 
to supply the U.S. ABWR certified design unless GE Nuclear Energy 
supplies the design for the applicant's use. Proposed paragraph 
IV.A.4.b would require that a COL applicant referencing the STPNOC 
certified design option include, as part of its application, a 
demonstration that an entity other than STPNOC and TANE acting together 
is qualified to supply the STPNOC certified design option, unless 
STPNOC and TANE acting together supply the design option for the 
applicant's use. In cases where a COL applicant is not using GE Nuclear 
Energy to supply the U.S. ABWR certified design, or is not using STPNOC 
and TANE acting together to supply the STPNOC certified design option, 
this information is necessary to support any NRC finding under 10 CFR 
52.73(a) that an entity other than the one originally sponsoring the 
design certification or design certification amendment is qualified to 
supply the certified design or certified design option.
    Under 10 CFR 52.47(a)(7), a design certification applicant is 
required to include information in its application to demonstrate that 
it is technically qualified to engage in the proposed activities (e.g., 
supplying the certified design to license applicants). Based on the 
NRC's review of the STPNOC application to amend to the U.S. ABWR 
certified design, the NRC determined that STPNOC and its contractors 
are technically qualified to perform the design work associated with 
the amended portion of the U.S. ABWR design represented by STPNOC's 
application and to supply the amended portion of the U.S. ABWR design. 
However, the staff determined that STPNOC, by itself, is not 
technically qualified to supply the amended portion of the U.S. ABWR 
design certification represented in STPNOC's DCD. Rather, the staff 
determined that STPNOC and TANE acting together are qualified to supply 
the amended portion of the U.S. ABWR design certification represented 
in STPNOC's DCD. Therefore, the NRC is including paragraph IV.A.4.b to 
ensure that the basis for the NRC finding of technical qualifications 
in support of this design certification amendment remains valid.
5. Applicable Regulations (Section V)
    The purpose of Section V is to specify the regulations applicable 
and in effect when the design certification is approved (i.e., as of 
the date specified in paragraph V.A, which is the date that Appendix A 
was originally approved by the Commission and signed by the Secretary 
of the Commission). The NRC is proposing to revise paragraph V.A to 
indicate that the current text in this paragraph applies to the GE DCD 
and to add a new paragraph indicating the regulations that apply to the 
STPNOC DCD (10 CFR Parts 50 and 52), as would be approved by the 
Commission and signed by the Secretary of the Commission should this 
amendment to Appendix A be approved. All of the requirements related to 
the NRC's AIA requirements can be found in 10 CFR Parts 50 and 52.
6. Issue Resolution (Section VI)
    The purpose of Section VI is to identify the scope of issues that 
were resolved by the Commission in the original certification 
rulemaking and, therefore, are ``matters resolved'' within the meaning 
and intent of 10 CFR 52.63(a)(5). Paragraph VI.B presents the scope of 
issues that may not be challenged as a matter of right in subsequent 
proceedings and describes the categories of information for which there 
is issue resolution. Paragraph VI.B.1 provides that all nuclear safety 
issues arising from the Atomic Energy Act of 1954, as amended, that are 
associated with the information in the NRC staff's FSER (ADAMS 
Accession No. ML102710198), the Tier 1 and Tier 2 information and the 
rulemaking record for this appendix are resolved within the meaning of 
10 CFR 52.63(a)(5). These issues include the information referenced in 
the DCD that are requirements (i.e., ``secondary references''), as well 
as all issues arising from proprietary information and SGI which are 
intended to be requirements. Paragraph VI.B.2 provides for issue 
preclusion of proprietary and SGI.
    The NRC is proposing to revise paragraphs VI.B.1 and VI.B.2 to 
redesignate references to the ``FSER'' as references to the ``ABWR 
FSER,'' and references to the ``generic DCD'' as references to the ``GE 
DCD'' to distinguish the FSER and DCD for the original certified design 
from the FSER and DCD that would be issued to support the STPNOC 
amendment to the U.S. ABWR design. In addition, this proposed revision 
would add additional text to paragraph VI.B.1 to identify the 
information that would be resolved by the Commission in the rulemaking 
to certify the STPNOC amendment to the U.S. ABWR design.
    The NRC is also proposing to revise paragraph VI.B.7, which 
identifies as resolved all environmental issues concerning severe 
accident mitigation design alternatives arising under the National 
Environmental Policy Act of 1969 (NEPA) associated with the information 
in the NRC's final environmental assessment for the U.S. ABWR design 
and Revision 1 of the technical support document for the U.S. ABWR, 
dated December 1994, for plants referencing this appendix whose site 
parameters are within those specified in the technical support 
document. The NRC is proposing to revise this paragraph to also 
identify as resolved all environmental issues concerning severe 
accident mitigation design alternatives associated with the information 
in the NRC's final environmental assessment and Revision 0 of ABWR-LIC-
09-621, ``Applicant's Supplemental Environmental Report-Amendment to 
ABWR Standard Design Certification,'' for the AIA amendment to the U.S. 
ABWR design for plants referencing this appendix whose site parameters 
are within those specified in the technical support document.
    Finally, the NRC is proposing to revise paragraph VI.E, which 
provides the procedure for an interested member of the public to obtain 
access to proprietary information and SGI for the U.S. ABWR design, and 
to request and participate in proceedings identified in paragraph VI.B 
of this appendix, that is, proceedings involving licenses and 
applications which reference this appendix. The NRC is proposing to 
replace the current information in this paragraph with a statement that 
the NRC will specify, at an appropriate time, the procedure for 
interested persons to review SGI or SUNSI (including proprietary 
information), for the purpose of participating in the hearing required 
by 10 CFR 52.85, the hearing provided under 10 CFR 52.103, or in any 
other proceeding relating to this appendix in which interested persons 
have a right to request an adjudicatory hearing.

[[Page 3553]]

    Access to such information would be for the sole purpose of 
requesting or participating in certain specified hearings, viz., (i) 
the hearing required by 10 CFR 52.85 where the underlying application 
references this appendix; (ii) any hearing provided under 10 CFR 52.103 
where the underlying COL references this appendix; and (iii) any other 
hearing relating to this appendix in which interested persons have the 
right to request an adjudicatory hearing.
    For proceedings where the notice of hearing was published before 
[effective date of final rule], the Commission's order governing access 
to SUNSI and SGI shall be used to govern access to SUNSI (including 
proprietary information) and SGI on the STPNOC option. For proceedings 
in which the notice of hearing or opportunity for hearing is published 
after [effective date of final rule], paragraph VI.E. applies and 
governs access to SUNSI (including proprietary information) and SGI for 
both the original GE certified design, and the STPNOC option; as stated 
in paragraph VI.E, the NRC will specify the access procedures at an 
appropriate time.
    The NRC expects to follow its current practice of establishing the 
procedures by order when the notice of hearing is published in the 
Federal Register. (See, e.g., Florida Power and Light Co, Combined 
License Application for the Turkey Point Units 6 & 7, Notice of 
Hearing, Opportunity To Petition for Leave To Intervene and Associated 
Order Imposing Procedures for Access to Sensitive Unclassified Non-
Safeguards Information and Safeguards Information for Contention 
Preparation (75 FR 34777; June 18, 2010); Notice of Receipt of 
Application for License; Notice of Consideration of Issuance of 
License; Notice of Hearing and Commission Order and Order Imposing 
Procedures for Access to Sensitive Unclassified Non-Safeguards 
Information and Safeguards Information for Contention Preparation; In 
the Matter of AREVA Enrichment Services, LLC (Eagle Rock Enrichment 
Facility) (74 FR 38052; July 30, 2009).
    In the four currently approved design certifications (10 CFR part 
52, Appendices A through D), paragraph VI.E presents specific 
directions on how to obtain access to proprietary information and SGI 
on the design certification in connection with a license application 
proceeding referencing that design certification rule. The NRC is 
proposing this change because these provisions were developed before 
the terrorist events of September 11, 2001. After September 11, 2001, 
the Congress changed the statutory requirements governing access to 
SGI, and the NRC revised its rules, procedures, and practices governing 
control and access to SUNSI and SGI. The NRC now believes that generic 
direction on obtaining access to SUNSI and SGI is no longer appropriate 
for newly approved DCRs. Accordingly, the specific requirements 
governing access to SUNSI and SGI contained in paragraph VI.E of the 
four currently approved DCRs should not be included in the design 
certification rule for the U.S. ABWR. Instead, the NRC should specify 
the procedures to be used for obtaining access at an appropriate time 
in the COL proceeding referencing the U.S. ABWR DCR. The NRC intends to 
include this change in any future amendment or renewal of the other 
existing DCRs. However, the NRC is not planning to initiate rulemaking 
to change paragraph VI.E of the existing DCRs, to minimize unnecessary 
resource expenditures by both the original DCR applicant and the NRC.
7. Processes for Changes and Departures (Section VIII)
    The purpose of Section VIII is to present the processes for generic 
changes to, or plant-specific departures (including exemptions) from, 
the DCD. The Commission adopted this restrictive change process to 
achieve a more stable licensing process for applicants and licensees 
that reference this DCR. The change processes for the three different 
categories of Tier 2 information, namely, Tier 2, Tier 2*, and Tier 2* 
with a time of expiration, are presented in paragraph VIII.B.
    Departures from Tier 2 that a licensee may make without prior NRC 
approval are addressed under paragraph VIII.B.5 (similar to the process 
in 10 CFR 50.59). The NRC is proposing changes to Section VIII to 
address the change control process specific to departures from the 
information required by 10 CFR 52.47(a)(28) to address the NRC's AIA 
requirements in 10 CFR 50.150. Specifically, the NRC is proposing to 
revise paragraph VIII.B.5.b to indicate that the criteria in this 
paragraph for determining if a proposed departure from Tier 2 requires 
a license amendment do not apply to a proposed departure affecting 
information required by 10 CFR 52.47(a)(28) to address 10 CFR 50.150. 
In addition, the NRC is proposing to redesignate paragraphs VIII.B.5.d, 
B.5.e, and B.5.f as paragraphs VIII.B.5.e, B.5.f, and B.5.g, 
respectively, and to add a new paragraph VIII.B.5.d. Proposed paragraph 
VIII.B.5.d would require an applicant or licensee who proposed to 
depart from the information required by 10 CFR 52.47(a)(28) to be 
included in the final safety analysis report (FSAR) for the standard 
design certification to consider the effect of the changed feature or 
capability on the original assessment required by 10 CFR 50.150(a). The 
FSAR information required by the aircraft impact rule which is subject 
to this change control requirement are the descriptions of the design 
features and functional capabilities incorporated into the final design 
of the nuclear power facility and the description of how the identified 
design features and functional capabilities meet the assessment 
requirements in 10 CFR 50.150(a)(1). The objective of the change 
controls is to determine whether the design of the facility, as changed 
or modified, is shown to withstand the effects of the aircraft impact 
with reduced use of operator actions. In other words, the applicant or 
licensee must continue to show, with the modified design, that the 
acceptance criteria in 10 CFR 50.150(a)(1) are met with reduced use of 
operator actions. The rule does not require an applicant or a licensee 
implementing a design change to redo the complete aircraft impact 
assessment (AIA) to evaluate the effects of the change. The NRC 
believes it may be possible to demonstrate that a design change is 
bound by the original design or that the change provides an equivalent 
level of protection, without redoing the original assessment.
    Consistent with the NRC's intent when it issued the AIA rule, under 
the proposed revision to this section, plant-specific departures from 
the AIA information in the FSAR would not require a license amendment, 
but may be made by the licensee upon compliance with the substantive 
requirements of the AIA rule (i.e., the AIA rule acceptance criteria). 
The applicant or licensee would also be required to document, in the 
plant-specific departure, how the modified design features and 
functional capabilities continue to meet the assessment requirements in 
10 CFR 50.150(a)(1) in accordance with Section X of this appendix. 
Applicants and licensees making changes to design features or 
capabilities included in the certified design may also need to develop 
alternate means to cope with the loss of large areas of the plant from 
explosions or fires to comply with the requirements in 10 CFR 
50.54(hh). The proposed addition of these provisions to this appendix 
is consistent with the NRC's intent when it issued the AIA rule in 
2009, as noted in the statements of consideration for that rule (74 FR

[[Page 3554]]

28112; June 12, 2009, at 28122, third column).
8. Records and Reporting (Section X)
    The purpose of Section X is to present the requirements that apply 
to maintaining records of changes to and departures from the generic 
DCD, which would be reflected in the plant-specific DCD. Section X also 
presents the requirements for submitting reports (including updates to 
the plant-specific DCD) to the NRC. Paragraph X.A.1 requires that a 
generic DCD and the proprietary information and SGI referenced in the 
generic DCD be maintained by the applicant for this rule. The NRC is 
proposing to revise paragraph X.A.1 to indicate that there are two 
applicants for this appendix and that the requirements to maintain a 
copy of the applicable generic DCD would apply to both the applicant 
for the original U.S. ABWR certification (GE) and the applicant for the 
AIA amendment to the U.S. ABWR design (STPNOC). Paragraph X.A.1 would 
also require the design certification applicant to maintain the 
proprietary information and SGI referenced in the generic DCD. The NRC 
is proposing to replace the term ``proprietary information'' with the 
broader term ``sensitive unclassified non-safeguards information 
(including proprietary information).'' Information categorized as SUNSI 
is information that is generally not publicly available and encompasses 
a wide variety of categories, including information about a licensee's 
or applicant's physical protection or material control and accounting 
program for special nuclear material not otherwise designated as SGI or 
classified as National Security Information or Restricted Data 
(security-related information), which is required by 10 CFR 2.390 to be 
protected in the same manner as commercial or financial information 
(i.e., they are exempt from public disclosure). This change is 
necessary because, although the NRC is not approving any proprietary 
information or SGI as part of this amendment rulemaking, it is 
approving some security-related information that is categorized as 
SUNSI.
    This change would ensure that both GE and STPNOC (as well as any 
future applicants for amendments to the U.S. ABWR DCR who intend to 
supply the certified design) are required to maintain a copy of the 
applicable generic DCD, and maintain the applicable SUNSI (including 
proprietary information) and SGI--developed by that applicant--that 
were approved as part of the relevant design certification rulemakings. 
In the certification of the original U.S. ABWR design, the NRC approved 
both proprietary information and SGI as part of the design 
certification rulemaking. In this amendment to the U.S. ABWR design, 
the NRC would only be approving non-proprietary SUNSI as part of the 
amendment rulemaking.
    The NRC notes that the generic DCD concept was developed, in part, 
to meet OFR requirements for incorporation by reference, including 
public availability of documents incorporated by reference. However, 
the proprietary information and SGI were not included in the public 
version of the DCD prepared by GE, and the SUNSI was not included in 
the public version of the DCD prepared by STPNOC. Only the public 
version of the generic STPNOC DCD would be identified and incorporated 
by reference into this rule. Nonetheless, the SUNSI for the STPNOC 
option was reviewed by the NRC and, as stated in paragraph VI.B.2, the 
NRC would consider the information to be resolved within the meaning of 
10 CFR 52.63(a)(5). Because this information is in the non-public 
versions of the GE and STPNOC DCDs, this SUNSI (including proprietary 
information) and SGI, or its equivalent, is required to be provided by 
an applicant for a license referencing this DCR.
    In addition, the NRC is proposing to add a new paragraph X.A.4.a 
that would require the applicant for the amendment to the U.S. ABWR 
design to address the AIA requirements to maintain a copy of the AIA 
performed to comply with the requirements of 10 CFR 50.150(a) for the 
term of the certification (including any period of renewal). The NRC is 
also proposing a new paragraph X.A.4.b that would require an applicant 
or licensee who references this appendix to include both the GE DCD and 
the STPNOC DCD to maintain a copy of the AIA performed to comply with 
the requirements of 10 CFR 50.150(a) throughout the pendency of the 
application and for the term of the license (including any period of 
renewal). The addition of paragraphs X.A.4.a and X.A.4.b is consistent 
with the NRC's intent when it issued the AIA rule in 2009 (74 FR 28112; 
June 12, 2009, at 28121, second column).

IV. Section-by-Section Analysis

A. Introduction (Section I)

    The NRC is proposing to amend Section I, ``Introduction,'' to 
identify STPNOC as the applicant for the amendment of the U.S. ABWR 
design certification rule to address the AIA rule, 10 CFR 50.150.

B. Definitions (Section II)

    The NRC is proposing to revise the definition of ``generic design 
control document (generic DCD)'' to indicate that there will be two 
generic DCDs incorporated by reference into this appendix--the DCD for 
the original U.S. ABWR design certification submitted by GE Nuclear 
Energy (GE DCD) and the DCD for the amendment to the U.S. ABWR design 
submitted by STPNOC (STPNOC DCD). This will make it clear that all 
requirements in this appendix related to the ``generic DCD'' apply to 
both the GE DCD and the STPNOC DCD, unless otherwise specified.

C. Scope and Contents (Section III)

    The NRC is proposing to redesignate existing paragraph A regarding 
the GE DCD as paragraph A.1 and to add a new paragraph A.2 indicating 
that the STPNOC DCD is also approved for incorporation by reference 
into 10 CFR part 52, Appendix A by OFR.
    The NRC is proposing to revise paragraph III.B to add text 
indicating that an applicant or licensee referencing this appendix may 
use either the GE DCD, or both the GE DCD and the STPNOC DCD. By doing 
so, the applicant or licensee effectively indicates which generic 
design it is using (i.e., the GE certified design, or the GE/STPNOC 
composite certified design). An applicant referencing this appendix 
would be required to indicate in its application and in all necessary 
supporting documentation which of these two alternatives it is 
implementing.
    The NRC is proposing a minor change to paragraph III.C, which 
currently states that, if there is a conflict between Tier 1 and Tier 2 
of the DCD, then Tier 1 controls. The revised paragraph would state 
that, if there is a conflict between Tier 1 and Tier 2 of a DCD, then 
Tier 1 controls, because the requirement would also apply to the STPNOC 
DCD.
    Paragraph III.D establishes the generic DCD as the controlling 
document in the event of an inconsistency between the DCD and the FSER 
for the certified standard design. The NRC is proposing a change to 
paragraph III.D which would indicate that in the event of an 
inconsistency between the STPNOC DCD and the AIA FSER, the STPNOC DCD 
controls.
    The NRC is proposing to redesignate current paragraph III.E as 
proposed paragraph III.F and to add a new paragraph III.E. Proposed 
paragraph III.E would state that, if there is a conflict between the 
design as described in the GE DCD and a design matter which implements 
the STPNOC certified

[[Page 3555]]

design option but is not specifically described in the STPNOC DCD, then 
the GE DCD controls.

D. Additional Requirements and Restrictions (Section IV)

    The NRC is proposing to revise paragraph IV.A.3 to indicate that a 
COL applicant must include, in the plant-specific DCD, the proprietary 
information and SGI referenced in both the GE DCD and the STPNOC DCD, 
as applicable, or its equivalent.
    Section IV presents additional requirements and restrictions 
imposed upon an applicant who references this appendix. Paragraph IV.A 
presents the information requirements for these applicants. Paragraph 
IV.A.3 requires the applicant to include the proprietary information 
and SGI referenced in the DCD, or its equivalent, to ensure that the 
applicant has actual notice of these requirements. The NRC is proposing 
to revise paragraph IV.A.3 to indicate that a COL applicant must 
include, in the plant-specific DCD, the proprietary information and SGI 
referenced in both the GE DCD and the STPNOC DCD, as applicable, or the 
equivalent of this information. If the COL applicant is referencing 
only the GE DC, then the applicant must include the proprietary 
information and SGI developed by GE (as presented in the non-public 
version of the GE DCD), or the equivalent of this information. If the 
COL applicant is referencing both the GE DCD and the STPNOC DCD, then 
the applicant must include: (1) The proprietary information and SGI 
developed by GE (as presented in the non-public version of the GE DCD), 
or the equivalent of this information; and (2) the proprietary 
information and SGI developed by STPNOC (as presented in the non public 
version of the STPNOC DCD), or the equivalent of this information.
    The NRC is also proposing to add a new paragraph IV.A.4 to indicate 
requirements that must be met in cases where the COL applicant is not 
using the entity that was the original applicant for the design 
certification (or amendment) to supply the design for the applicant's 
use. Proposed paragraph IV.A.4.a would require that a COL applicant 
referencing this appendix include, as part of its application, a 
demonstration that an entity other than GE is qualified to supply the 
U.S. ABWR certified design unless GE supplies the design for the 
applicant's use. Proposed paragraph IV.A.4.b would require that a COL 
applicant referencing the STPNOC certified design option include, as 
part of its application, a demonstration that an entity other than 
STPNOC and TANE acting together is qualified to supply the STPNOC 
certified design option, unless STPNOC and TANE acting together supply 
the design option for the applicant's use. In cases where a COL 
applicant is not using GE to supply the U.S. ABWR certified design, or 
is not using STPNOC and TANE acting together to supply the STPNOC 
certified design option, the required information would be used to 
support any NRC finding under 10 CFR 52.73(a) that an entity other than 
the one originally sponsoring the design certification or design 
certification amendment is qualified to supply the certified design or 
certified design option.

E. Applicable Regulations (Section V)

    Paragraph V.A would be revised so that the first sentence of 
paragraph V.A identifies the applicable regulations for the GE 
certified design, and the second sentence presents the applicable 
regulations for the STPNOC Option.

F. Issue Resolution (Section VI)

    The NRC is proposing to revise paragraphs VI.B.1 and VI.B.2 to 
redesignate references to the ``FSER'' as references to the ``ABWR 
FSER'' and references to the ``generic DCD'' as references to the ``GE 
DCD'' to distinguish the FSER and DCD for the original certified design 
from the FSER and DCD that would be issued to support the STPNOC 
amendment to the U.S. ABWR design. In addition, this proposed revision 
would add text to paragraph VI.B.1 to identify the information that 
would be resolved by the Commission in the rulemaking to certify the 
STPNOC AIA amendment to the U.S. ABWR design.
    The NRC is proposing to revise paragraph VI.B.7 to identify as 
resolved all environmental issues concerning severe accident mitigation 
design alternatives associated with the information in the NRC's final 
environmental assessment and Revision 0 of ABWR-LIC-09-621, 
``Applicant's Supplemental Environmental Report-Amendment to ABWR 
Standard Design Certification,'' for the AIA amendment to the U.S. ABWR 
design for plants referencing this appendix whose site parameters are 
within those specified in the technical support document. The existing 
site parameters specified in the technical support document are not 
affected by this design certification amendment.

G. Processes for Changes and Departures (Section VIII)

    The NRC is proposing changes to Section VIII to address the change 
control process specific to departures from the information required by 
10 CFR 52.47(a)(28) to address the NRC's AIA requirements in 10 CFR 
50.150. Specifically, the NRC is proposing to revise paragraph 
VIII.B.5.b to indicate that the criteria in this paragraph for 
determining if a proposed departure from Tier 2 requires a license 
amendment do not apply to a proposed departure affecting information 
required by 10 CFR 52.47(a)(28) to address aircraft impacts.
    In addition, the NRC is proposing to redesignate paragraphs 
VIII.B.5.d, B.5.e, and B.5.f as paragraphs VIII.B.5.e, B.5.f, and 
B.5.g, respectively, and to add a new paragraph VIII.B.5.d. Proposed 
paragraph VIII.B.5.d would require an applicant referencing the U.S. 
ABWR DCR, who proposed to depart from the information required by 10 
CFR 52.47(a)(28) to be included in the FSAR for the standard design 
certification, to consider the effect of the changed feature or 
capability on the original 10 CFR 50.150(a) assessment.

H. Records and Reporting (Section X)

    The NRC is proposing to revise paragraph X.A.1 to refer to 
``applicants'' for this appendix and to replace the term ``proprietary 
information'' with the broader term ``sensitive unclassified non-
safeguards information.'' Paragraph X.A.1 would be revised to require 
the design certification amendment applicant to maintain the SUNSI 
which it developed and used to support its design certification 
amendment application. This would ensure that the referencing applicant 
has direct access to this information from the design certification 
amendment applicant, if it has contracted with the applicant to provide 
the SUNSI to support its license application. The STPNOC generic DCD 
and the NRC-approved version of the SUNSI would be required to be 
maintained for the period that this appendix may be referenced.
    The NRC is also proposing to add a new paragraph X.A.4.a that would 
require STPNOC to maintain a copy of the AIA performed to comply with 
the requirements of 10 CFR 50.150(a) for the term of the certification 
(including any period of renewal). This proposed provision, which is 
consistent with 10 CFR 50.150(c)(3), would facilitate any NRC 
inspections of the assessment that the NRC decides to conduct.
    Similarly, the NRC is proposing new paragraph X.A.4.b that would 
require an applicant or licensee who references this appendix, to 
include both the GE DCD and the STPNOC DCD, to maintain a copy of the 
AIA performed to comply with the requirements of 10 CFR 50.150(a) 
throughout the pendency of

[[Page 3556]]

the application and for the term of the license (including any period 
of renewal). This provision is consistent with 10 CFR 50.150(c)(4). For 
all applicants and licensees, the supporting documentation retained 
onsite should describe the methodology used in performing the 
assessment, including the identification of potential design features 
and functional capabilities to show that the acceptance criteria in 10 
CFR 50.150(a)(1) would be met.

V. Agreement State Compatibility

    Under the ``Policy Statement on Adequacy and Compatibility of 
Agreement States Programs,'' approved by the Commission on June 20, 
1997, and published in the Federal Register (62 FR 46517; September 3, 
1997), this rule is classified as compatibility ``NRC.'' Compatibility 
is not required for Category ``NRC'' regulations. The NRC program 
elements in this category are those that relate directly to areas of 
regulation reserved to the NRC by the AEA or the provisions of this 
chapter. Although an Agreement State may not adopt program elements 
reserved to the NRC, it may wish to inform its licensees of certain 
requirements by a mechanism that is consistent with the particular 
State's administrative procedure laws. Category ``NRC'' regulations do 
not confer regulatory authority on the State.

VI. Availability of Documents

    The NRC is making the documents identified below available to 
interested persons through one or more of the following methods, as

VII. Procedures for Access to Sensitive Unclassified Non-Safeguards 
Information for Preparation of Comments on the Proposed Amendment to 
the U.S. ABWR Design Certification

    This section contains instructions regarding how interested persons 
who wish to comment on the proposed design certification amendment may 
request access to documents containing SUNSI to prepare their comments.

Submitting a Request to the NRC

    Within 10 days after publication of this document, an individual or 
entity (thereinafter, the ``requester'') may request access to such 
information. Requests for access to SUNSI submitted more than 10 days 
after publication of this document will not be considered absent a 
showing of good cause for the late filing explaining why the request 
could not have been filed earlier.
    The requester shall submit a letter requesting permission to access 
SUNSI to the Office of the Secretary, U.S. Nuclear Regulatory 
Commission, Attention: Rulemakings and Adjudications Staff, Washington, 
DC 20555-0001. The expedited delivery or courier mail address is: 
Office of the Secretary, U.S. Nuclear Regulatory Commission, Attention: 
Rulemakings and Adjudications Staff, 11555 Rockville Pike, Rockville, 
Maryland 20852. The e-mail address for the Office of the Secretary is 
<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="80f2f5ece5ede1ebe9eee7aee3efedede5eef4f3c0eef2e3aee7eff6">[email protected]</a>. The requester must send a copy of the 
request to the design certification applicant at the same time as the 
original transmission to the NRC using the same method of transmission. 
Copies of the request to the applicant must be sent to Mr. Scott M. 
Head, Regulatory Affairs Manager, South Texas Project Nuclear Operating 
Company, P.O. Box 289, Wadsworth, TX 77483, or to <a href="/cdn-cgi/l/email-protection#dba8b6b3bebabf9b888f8b9e9c88f5b8b4b6"><span class="__cf_email__" data-cfemail="1467797c717570544740445153473a777b79">[email protected]</span></a>. 
For purposes of complying with this requirement, a ``request'' includes 
all the information required to be submitted to the NRC as presented in 
this section.
    The request must include the following information:
    1. The name of this design certification amendment at the top of 
the first page of the request, and a citation to this document.
    2. The name, address, and e-mail or FAX number of the requester. If 
the requester is an entity, the name of the individual(s) to whom 
access is to be provided, then the address and e-mail or FAX number for 
each individual, and a

[[Page 3557]]

statement of the authority granted by the entity to each individual to 
review the information and to prepare comments on behalf of the entity 
must be provided. If the requester is relying upon another individual 
to evaluate the requested SUNSI and prepare comments, then the name, 
affiliation, address, and e-mail or FAX number for that individual must 
be provided.
    3. The requester's need for the information to prepare meaningful 
comments on the proposed design certification must be demonstrated. 
Each of the following areas must be addressed with specificity.
    (a) The specific issue or subject matter on which the requester 
wishes to comment;
    (b) An explanation why information which is publicly available, 
including the publicly available versions of the application and design 
control document, and information on the NRC's docket for the design 
certification application is insufficient to provide the basis for 
developing meaningful comment on the proposed design certification with 
respect to the issue or subject matter described previously in 
paragraph 3(a); and
    (c) Information demonstrating that the individual to whom access is 
to be provided has the technical competence (demonstrable knowledge, 
skill, experience, education, training or certification) to understand 
and use (or evaluate) the requested information in order to develop 
meaningful comments on the proposed design certification with respect 
to the issue or subject matter described in paragraph 3(a) above.
    4. Based on an evaluation of the information submitted under 
paragraph 3 of this section, the NRC staff will determine within 10 
days of receipt of the written access request whether the requester has 
established a legitimate need for the SUNSI access requested.
    5. If the NRC staff determines that the requester has established a 
legitimate need for access to SUNSI, the NRC staff will notify the 
requester in writing that access to SUNSI has been granted.
    The written notification to the requester will contain instructions 
on how the requester may obtain copies of the requested documents, and 
any other conditions that may apply to access to those documents. These 
conditions will include, but are not necessarily limited to, the 
signing of a protective order presenting terms and conditions to 
prevent the unauthorized or inadvertent disclosure of SUNSI by each 
individual who will be granted access to SUNSI. Claims that the 
provisions of such a protective order have not been complied with may 
be filed by calling NRC's toll-free safety hotline at 1-800-695-7403. 
Please note that calls to this number are not recorded between the 
hours of 7 a.m. to 5 p.m. Eastern Time. However, calls received outside 
these hours are answered by the Incident Response Operations Center on 
a recorded line. Claims may also be filed via e-mail to <a href="/cdn-cgi/l/email-protection#d49a869b8b95b8b8b1b3b5a0bdbbbaa794baa6b7fab3bba2"><span class="__cf_email__" data-cfemail="da948895859bb6b6bfbdbbaeb3b5b4a99ab4a8b9f4bdb5ac">[email protected]</span></a>, or may be sent in writing to the U.S. Nuclear 
Regulatory Commission, Attention: N. Rivera-Feliciano, Mail Stop T7-
D24, Washington, DC 20555-0001.
    6. Any comments in this rulemaking proceeding that are based upon 
the disclosed SUNSI must be filed by the requester no later than 25 
days after receipt of (or access to) that information, or the close of 
the public comment period, whichever is later. The commenter must 
comply with the NRC requirements regarding the submission of SUNSI to 
the NRC when submitting comments to the NRC (including marking and 
transmission requirements).
    7. Review of Denials of Access.
    (a) If the request for access to SUNSI is denied by the NRC staff, 
the staff shall promptly notify the requester in writing, briefly 
stating the reason or reasons for the denial.
    (b) Appeals from a denial of access must be made to the Executive 
Director for Operations (EDO) in accordance with 10 CFR 9.29. The 
decision of the EDO constitutes final agency action, as provided in 10 
CFR 9.29(d).

VIII. Plain Language

    The Presidential memorandum `Plain Language in Government Writing'' 
published on June 10, 1998 (63 FR 31883), directed that the 
Government's documents be in clear and accessible language. The NRC 
requests comments on the proposed rule specifically with respect to the 
clarity and effectiveness of the language used. Comments should be sent 
to the NRC as explained in the ADDRESSES heading of this document.

IX. Voluntary Consensus Standards

    The National Technology and Transfer Act of 1995 (Act), Public Law 
104-113, requires that Federal agencies use technical standards that 
are developed or adopted by voluntary consensus standards bodies unless 
using such a standard is inconsistent with applicable law or is 
otherwise impractical. The NRC proposes to approve the AIA amendment to 
the U.S. ABWR standard plant design for use in nuclear power plant 
licensing under 10 CFR part 50 or 52. Design certifications (and 
amendments thereto) are not generic rulemakings establishing a 
generally applicable standard with which all 10 CFR Parts 50 and 52 
nuclear power plant licensees must comply. Design certifications (and 
amendments thereto) are Commission approvals of specific nuclear power 
plant designs by rulemaking. Furthermore, design certifications (and 
amendments thereto) are initiated by an applicant for rulemaking, 
rather than by the NRC. For these reasons, the NRC concludes that the 
Act does not apply to this proposed rule.

X. Finding of No Significant Environmental Impact: Availability

    The Commission has determined under NEPA, and the Commission's 
regulations in Subpart A, ``National Environmental Policy Act; 
Regulations Implementing Section 102(2),'' of 10 CFR part 51, 
``Environmental Protection Regulations for Domestic Licensing and 
Related Regulatory Functions,'' that this proposed design certification 
rule, if adopted, would not be a major Federal action significantly 
affecting the quality of the human environment and, therefore, an 
environmental impact statement (EIS) is not required. The basis for 
this determination, as documented in the draft environmental assessment 
(EA), is that that the Commission has made a generic determination 
under 10 CFR 51.32(b)(2) that there is no significant environmental 
impact associated with the issuance of an amendment to a design 
certification.
    This amendment to 10 CFR part 52 would not authorize the siting, 
construction, or operation of a facility using the AIA amendment to the 
U.S. ABWR design; it would only codify the AIA amendment to the U.S. 
ABWR design in a rule. The NRC will evaluate the environmental impacts 
and issue an EIS as appropriate under NEPA as part of the application 
for the construction and operation of a facility referencing the AIA 
amendment to the U.S. ABWR design certification rule.
    In addition, as part of the draft EA for the AIA amendment to the 
U.S. ABWR design, the NRC reviewed STPNOC's evaluation of various 
design alternatives to prevent and mitigate severe accidents in 
Revision 0 of ABWR-LIC-09-621, ``Applicant's Supplemental Environmental 
Report-Amendment to ABWR Standard Design Certification.'' According to 
10 CFR 51.30(d), an EA for a design certification amendment is limited 
to the consideration of whether the design change which is the subject 
of the proposed amendment renders a severe accident mitigation design 
alternative (SAMDA) previously rejected in the earlier EA to become 
cost

[[Page 3558]]

beneficial, or results in the identification of new SAMDAs, in which 
case the costs and benefits of new SAMDAs and the bases for not 
incorporating new SAMDAs in the design certification must be addressed. 
Based upon review of STPNOC's evaluation, the Commission concludes that 
the proposed design changes (1) do not cause a SAMDA previously 
rejected in the environmental assessment for the original U.S. ABWR 
design certification to become cost-beneficial; and (2) do not result 
in the identification of any new SAMDAs that could become cost 
beneficial.
    The Commission is requesting comment on the draft EA. As provided 
in 10 CFR 51.31(b), comments on the draft EA will be limited to the 
consideration of SAMDAs as required by 10 CFR 51.30(d). The Commission 
will prepare a final EA following the close of the comment period for 
the proposed standard design certification. If a final rule is issued, 
all environmental issues concerning SAMDAs associated with the 
information in the final EA and Revision 0 of ABWR-LIC-09-621, 
``Applicant's Supplemental Environmental Report-Amendment to ABWR 
Standard Design Certification,'' will be considered resolved for plants 
referencing the AIA amendment to the U.S. ABWR design whose site 
parameters are within those specified in Revision 1 of the technical 
support document for the U.S. ABWR, dated December 1994. The existing 
site parameters specified in the technical support document are not 
affected by this design certification amendment.
    The draft EA, upon which the Commission's finding of no significant 
impact is based, and the STPNOC DCD are available for examination and 
copying at the NRC's Public Document Room (PDR), One White Flint North, 
11555 Rockville Pike, Room O1-F21, Rockville, Maryland 20852.

XI. Paperwork Reduction Act Statement

    This proposed rule contains new or amended information collection 
requirements that are subject to the Paperwork Reduction Act of 1995 
(44 U.S.C. 3501 et seq.). This rule has been submitted to the Office of 
Management and Budget (OMB) for review and approval of the information 
collection requirements.
    Type of submission, new or revision: Revision.
    The title of the information collection: 10 CFR part 52, Advanced 
Boiling Water Reactor Aircraft Impact Design Certification Amendment.
    The form number if applicable: N/A.
    How often the collection is required: On occasion. Reports required 
under 10 CFR part 52, Appendix A, paragraph IV.A.4, are collected and 
evaluated once, when licensing action is sought on a combined license 
application referencing the U.S. ABWR design and the combined license 
applicant is not using the entity that was the original applicant for 
the design certification, or amendment, to supply the design for the 
license applicant's use.
    Who will be required or asked to report: Combined license 
applicants.
    An estimate of the number of annual responses: 2 (0 annual 
responses plus 2 recordkeepers).
    The estimated number of annual respondents: 2.
    An estimate of the total number of hours needed annually to 
complete the requirement or request: 6 hours (0 hours reporting and 6 
hours recordkeeping).
    Abstract: The NRC proposes to amend its regulations to certify an 
amendment to the U.S. ABWR standard plant design to comply with 10 CFR 
50.150, ``Aircraft Impact Assessment.'' This action will allow 
applicants or licensees intending to construct and operate a U.S. ABWR 
to comply with 10 CFR 50.150 by referencing the amended DCR.
    The NRC is seeking public comment on the potential impact of the 
information collections contained in this proposed rule (or proposed 
policy statement) and on the following issues:
    1. Is the proposed information collection necessary for the proper 
performance of the functions of the NRC, including whether the 
information will have practical utility?
    2. Is the estimate of burden accurate?
    3. Is there a way to enhance the quality, utility, and clarity of 
the information to be collected?
    4. How can the burden of the information collection be minimized, 
including the use of automated collection techniques?
    A copy of the OMB clearance package may be viewed free of charge at 
the NRC's PDR, One White Flint North, 11555 Rockville Pike, Room O1-
F21, Rockville, Maryland 20852. The OMB clearance package and rule are 
available at the NRC worldwide Web site: http://www.nrc.gov/public-involve/doc-comment/omb/index.html for 60 days after the signature date 
of this notice.

Public Protection Notification

    The NRC may not conduct or sponsor, and a person is not required to 
respond to, a request for information or an information collection 
requirement unless the requesting document displays a currently valid 
OMB control number.

XII. Regulatory Analysis

    The NRC has not prepared a regulatory analysis for this proposed 
rule. The NRC prepares regulatory analyses for rulemakings that 
establish generic regulatory requirements applicable to all licensees. 
Design certifications (and amendments thereto) are not generic 
rulemakings in the sense that design certifications (and amendments 
thereto) do not establish standards or requirements with which all 
licensees must comply. Rather, design certifications (and amendments 
thereto) are Commission approvals of specific nuclear power plant 
designs by rulemaking, which then may be voluntarily referenced by 
applicants for COLs. Furthermore, design certification rulemakings are 
initiated by an applicant for a design certification (or amendments 
thereto), rather than the NRC. Preparation of a regulatory analysis in 
this circumstance would not be useful because the design to be 
certified is proposed by the applicant rather than the NRC. For these 
reasons, the Commission concludes that preparation of a regulatory 
analysis is neither required nor appropriate.

XIII. Regulatory Flexibility Act Certification

    Under the Regulatory Flexibility Act (5 U.S.C. 605(b)), the 
Commission certifies that this rule would not, if promulgated, have a 
significant economic impact on a substantial number of small entities. 
This proposed rule provides for certification of an

[[Page 3559]]

amendment to a nuclear power plant design. Neither the design 
certification amendment applicant, nor prospective nuclear power plant 
licensees who reference this design certification rule, fall within the 
scope of the definition of ``small entities'' presented in the 
Regulatory Flexibility Act, or the size standards established by the 
NRC (10 CFR 2.810). Thus, this rule does not fall within the purview of 
the Regulatory Flexibility Act.

XIV. Backfitting

    The Commission has determined that this proposed rule does not 
constitute a backfit as defined in the backfit rule (10 CFR 50.109) 
because this design certification amendment does not impose new or 
changed requirements on existing 10 CFR part 50 licensees, nor does it 
impose new or changed requirements on existing DCRs in Appendices A 
through D of 10 CFR part 52. Therefore, a backfit analysis was not 
prepared for this rule.
    The proposed rule does not constitute backfitting as defined in the 
backfit rule (10 CFR 50.109) with respect to either operating licenses 
under 10 CFR part 50 because there are no operating licenses 
referencing this design certification rule. The proposed rule does not 
constitute backfitting as defined in the backfit rule or otherwise 
impose requirements inconsistent with the applicable finality 
requirements under 10 CFR part 52 (10 CFR 52.63, 52.83 and 52.98) 
because: (i) There are no COLs issued by the NRC referencing this rule, 
and (ii) neither the backfit rule nor the finality provisions in 10 CFR 
part 52 protect COL applicants from changes in NRC requirements which 
may occur during the pendency of their application before the NRC.
    The proposed rule is not inconsistent with the finality 
requirements in 10 CFR 52.63 as applied to COLs. The proposed rule 
would establish an option to the existing design certification rule 
which addresses the requirements of the AIA rule. A COL referencing the 
U.S. ABWR design certification rule may voluntarily choose to select 
the STPNOC option, or may choose to reference the U.S. ABWR design 
without selecting the STPNOC option.
    The AIA rule itself mandated that the U.S. ABWR DCR be revised 
(either during the DCR's current term or no later than its renewal) to 
address the requirements of the AIA rule. The AIA rule may therefore be 
regarded as inconsistent with applicable finality provisions in 10 CFR 
part 52 and Section VI of the U.S. ABWR DCR. However, the NRC provided 
an administrative exemption from these finality requirements when the 
final AIA rule was issued. See 74 FR 28112; June 12, 2009, at 28143-45. 
Accordingly, the NRC has already addressed the backfitting implications 
of applying the AIA rule to the U.S. ABWR.
    Because the proposed rule does not constitute backfitting and is 
not otherwise inconsistent with finality provisions in 10 CFR part 52, 
the NRC has not prepared a backfit analysis or documented evaluation 
for this rule.

assessment (PRA) in the ABWR standard safety analysis report do not 
incorporate the PRA into Tier 2.
    C. If there is a conflict between Tier 1 and Tier 2 of a DCD, 
then Tier 1 controls.
    D. If there is a conflict between the generic DCD and the 
application for design certification of the U.S. ABWR design, NUREG-
1503, ``Final Safety Evaluation Report related to the Certification 
of the Advanced Boiling Water Reactor Design'' (ABWR FSER), and 
Supplement No. 1, or NUREG-XXXX ``Final Safety Evaluation Report 
related to the Certification of the AIA Amendment to the ABWR 
Design'' (AIA FSER), then the generic DCD controls.
    E. If there is a conflict between the design as described in the 
GE DCD and a design matter which implements the STPNOC certified 
design option but is not specifically described in the STPNOC DCD, 
then the GE DCD controls.
    F. Design activities for structures, systems, and components 
that are wholly outside the scope of this appendix may be performed 
using site characteristics, provided the design activities do not 
affect the DCD or conflict with the interface requirements.

IV. Additional Requirements and Restrictions
