Abstract

The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its regulations to renew the AP1000 design certification and incorporate Revision 20 of the AP1000 design control document. The purpose of this rulemaking action is to update the AP1000 design to be consistent with changes made to the design during the licensing, construction, and operation of Vogtle Electric Generating Plant, Units 3 and 4. This rulemaking incorporates AP1000 design control document Revision 20, which includes updates made to the AP1000 design to represent a current, construction-validated design. The NRC also proposes to issue an environmental assessment supporting this rule.

state that the NRC does not routinely edit comment submissions to 
remove such information before making the comment submissions available 
to the public or entering the comment into ADAMS.

II. Rulemaking Procedure

    Because the NRC considers this action to be non-controversial, the 
NRC is publishing this proposed rule concurrently with a direct final 
rule in the Rules and Regulations section of this issue of the Federal 
Register. The direct final rule will become effective on December 28, 
2026. However, if the NRC receives significant adverse comments by 
November 13, 2026, then the NRC will publish a document that withdraws 
the direct final rule. If the direct final rule is withdrawn, the NRC 
will address the comments in a subsequent final rule. Absent 
significant modifications to the proposed revisions requiring 
republication, the NRC will not initiate a second comment period on 
this action in the event the direct final rule is withdrawn.
    A significant adverse comment is a comment where the commenter 
explains why the rule would be inappropriate, including challenges to 
the rule's underlying premise or approach, or would be ineffective or 
unacceptable without a change. A comment is adverse and significant if:
    (1) The comment opposes the rule and provides a reason sufficient 
to require a substantive response in a notice-and-comment process. For 
example, a substantive response is required when:
    (a) The comment causes the NRC to reevaluate (or reconsider) its 
position or conduct additional analysis;
    (b) The comment raises an issue serious enough to warrant a 
substantive response to clarify or complete the record; or
    (c) The comment raises a relevant issue that was not previously 
addressed or considered by the NRC.
    (2) The comment proposes a change or an addition to the rule, and 
it is apparent that the rule would be ineffective or unacceptable 
without incorporation of the change or addition.
    (3) The comment causes the NRC to make a change (other than 
editorial) to the rule.
    For procedural information and the regulatory analysis, see the 
direct final rule published in the Rules and Regulations section of 
this issue of the Federal Register.

III. Background

    The NRC originally approved the AP1000 design certification in a 
final rule published on January 27, 2006 (71 FR 4464). On December 30, 
2011 (76 FR 82079), the NRC published a final rule amending appendix D, 
``Design Certification Rule for the AP1000 Design,'' to part 52, 
``Licenses, Certifications, and Approvals for

[[Page 65135]]

Nuclear Power Plants,'' of title 10 of the Code of Federal Regulations 
(10 CFR) to incorporate AP1000 Design Control Document (DCD), Revision 
19, APP-GW-GL-702, dated June 13, 2011. On September 22, 2021 (86 FR 
52593), the NRC published a direct final rule extending the duration of 
the AP1000 design certification by five years, with an effective date 
of December 6, 2021.
    On July 2, 2025 (90 FR 28869), the NRC amended its regulations to 
replace the 15-year duration of design certifications with a 40-year 
duration, both for existing design certifications currently in effect 
and generically for future design certifications, including renewals. 
The NRC did not change the date of issuance or renewal for existing 
design certifications but changed their expiration dates based on the 
most recent date of issuance or renewal. The current AP1000 design 
certification expires on February 27, 2046.
    On February 10, 2012, the NRC issued combined licenses (COLs) to 
Southern Nuclear Operating Company (SNC) for the Vogtle Electric 
Generating Plant (VEGP) Units 3 and 4 (COLs NPF-91 and NPF-92). During 
the licensing, construction, and operation of VEGP Units 3 and 4, SNC 
submitted over 180 license amendment requests (LARs) to the NRC 
addressing design changes, construction-discovered issues, and 
operational refinements. The NRC reviewed and approved these LARs 
through safety evaluations for each approved amendment. In addition, 
SNC implemented numerous Tier 2 departures under the section VIII.B.5 
of appendix D to 10 CFR part 52 change process that did not require 
prior NRC approval. The VEGP licensing process also resolved the COL 
action items identified in DCD Revision 19 with site-specific design 
details, operational program descriptions, and as-built information. 
The VEGP Unit 3 entered commercial operation on July 31, 2023, and Unit 
4 did so on April 29, 2024.
    In SECY-26-0034, ``NRC Regulatory Pathways and Licensing Readiness 
for Near Term Large Light-Water Reactor Deployment,'' dated March 9, 
2026, the NRC staff informed the Commission, among other things, that 
it anticipated submission of the Westinghouse Electric Company LLC 
(Westinghouse) application to update and renew the AP1000 design 
certification. The NRC staff also informed the Commission of its plan 
to incorporate the as-built changes incorporated into VEGP Units 3 and 
4, previously approved safety findings, and lessons learned into a 
revised AP1000 design certification. The NRC's verification review 
determined that no new changes were incorporated into AP1000 DCD 
Revision 20 that require additional technical review, and that all 
changes incorporated into the AP1000 DCD Revision 20 were either 
previously reviewed and approved by the NRC or were incorporated using 
a process that does not require NRC approval. Therefore, the NRC is 
using the direct final rule process to update appendix D to 10 CFR part 
52 to include AP1000 DCD Revision 20. This renewal would improve 
regulatory clarity, avoid unnecessary re-review, and streamline future 
AP1000 licensing activities by providing applicants with an updated, 
standardized design basis. The NRC is amending appendix D to 10 CFR 
part 52 to include AP1000 DCD Revision 20. The NRC is also retaining 
the incorporation by reference of AP1000 DCD Revision 19 in appendix D 
to 10 CFR part 52 because several combined license holders were 
licensed to AP1000 Revision 19 and the incorporation of the AP1000 DCD 
Revision 19 in appendix D to 10 CFR part 52 remains part of the 
licensing basis for those combined license holders. Applicants could 
reference either revision in future applications.
    While 10 CFR 52.63(a) imposes restrictive limits on the types of 
changes that may be made while a design certification rule is in 
effect, 10 CFR 52.59(c) allows a design certification renewal applicant 
greater flexibility in seeking changes to the design certification. 
Thus, a design certification renewal application that includes 
amendments to a certified design is not required to address the 
criteria in 10 CFR 52.63, ``Finality of standard design 
certifications.'' However, if the amendment request entails such an 
extensive change to the design certification that an essentially new 
standard design is being proposed, 10 CFR 52.59(c) provides that an 
application for a design certification must be filed. The AP1000 
amendment request does not propose an essentially new standard design.
    The NRC is amending the design certification for the AP1000 
standard plant design to renew the AP1000 design certification for 40 
years from the effective date of the direct final rule. The NRC 
determined the submitted application for incorporation by reference of 
DCD Revision 20 into appendix D to 10 CFR part 52 is acceptable. 
Further, the Commission granted an exemption from 10 CFR 52.57(a) to 
allow renewal more than 36 months before expiration of the current 
design certification rule (91 FR 40596; July 2, 2026). The requirements 
of 10 CFR 52.55, ``Duration of certification,'' govern the duration of 
a design certification and the effect of timely renewal. The AP1000 
design certification rule does not expire until 2046.
    The NRC is amending section VIII.B.6 of appendix D to 10 CFR part 
52 to incorporate the alternative change process that was previously 
reviewed and approved for Vogtle Units 3 and 4 into appendix D to 10 
CFR part 52. The license amendments and exemptions included in AP1000 
DCD Revision 20 include a previously reviewed and approved change 
process for Tier 2* information. On December 21, 2017, SNC submitted 
LAR-17-037, and an associated exemption request, seeking changes to the 
Vogtle Units 3 and 4 COLs to add a license condition that would apply 
the change process for Tier 2 information for a proposed departure from 
Tier 2* information provided that specific criteria are not met. If one 
of the criteria were met for the proposed departure, then the proposed 
departure would continue to require prior NRC approval. On September 
20, 2018, the NRC granted the amendments and exemptions to Vogtle Units 
3 and 4 that effectively replaced the Tier 2* change process with an 
alternative process (reflected in a license condition) that applied the 
Tier 2 change process along with nine additional criteria to determine 
whether a license amendment was required. Inclusion of this change 
process in section VIII.B.6 of appendix D to 10 CFR part 52 promotes 
regulatory efficiency by eliminating the need for unnecessary licensing 
actions for applicants referencing either AP1000 DCD Revision 19 or 
AP1000 DCD Revision 20.

IV. Plain Writing

    The Plain Writing Act of 2010 (Pub. L. 111-274) requires Federal 
agencies to write documents in a clear, concise, and well-organized 
manner. The NRC has written this document to be consistent with the 
Plain Writing Act as well as the Presidential Memorandum, ``Plain 
Language in Government Writing,'' published June 10, 1998 (63 FR 
31885). The NRC requests comment on this proposed rule with respect to 
clarity and effectiveness of the language used.

V. National Environmental Policy Act: Environmental Assessment and 
Proposed Finding of No Significant Impact

    The NRC has determined under the National Environmental Policy Act 
of 1969, as amended (NEPA), and the NRC's regulations in subpart A, 
``National Environmental Policy Act--Regulations Implementing Section 
102(2),'' of 10 CFR part 51,

[[Page 65136]]

``Environmental Protection Regulations for Domestic Licensing and 
Related Regulatory Functions,'' that this proposed rule, if issued, 
would not be a major Federal action significantly affecting the quality 
of the human environment and, therefore, an environmental impact 
statement is not required. The NRC's generic determination in this 
regard, reflected in 10 CFR 51.32(b)(1), is based upon the following 
considerations: (1) A design certification rule does not authorize the 
siting, construction, or operation of a facility referencing any 
particular design, but only codifies a standard design certification in 
a rule (extending the AP1000 design certification and incorporating 
changes to the design in this case); (2) the NRC will evaluate the 
environmental impacts and issue an environmental finding in a Record of 
Decision as appropriate under NEPA as part of the application for the 
construction and operation of a facility referencing any particular 
design certification rule; and (3) comments on the environmental 
assessment will be limited to the consideration of severe accident 
mitigation design alternatives as required by 10 CFR 51.30(d). The 
environmental assessment is available in the companion direct final 
rule published in the Rules and Regulations section of this issue of 
the Federal Register. In keeping with Commission policy, that 
environmental assessment also updates the agency's consideration of 
severe accident mitigation design alternatives.

VI. Paperwork Reduction Act

    This proposed rule does not contain any new or amended collections 
of information subject to the Paperwork Reduction Act of 1995 (44 
U.S.C. 3501 et seq.). Existing collections of information were approved 
by the Office of Management and Budget, control number 3150-0151.

Public Protection Notification

    The NRC may not conduct or sponsor, and a person is not required to 
respond to, a collection of information unless the document requesting 
or requiring the collection displays a currently valid Office of 
Management and Budget control number.

VII. Executive Orders

    The following are Executive orders that are related to this 
proposed rule:

A. Executive Order 12866: Regulatory Planning and Review (as amended by 
E.O. 14215, Ensuring Accountability for All Agencies)

    The Office of Information and Regulatory Affairs (OIRA) has 
determined that this direct final rule is not a significant regulatory 
action.

B. Executive Order 14154: Unleashing American Energy

    The NRC has examined this proposed rule and has determined that it 
is consistent with the policies and directives outlined in E.O. 14154.

C. Executive Order 14192: Unleashing Prosperity Through Deregulation

    This action is determined to be a deregulatory action as defined by 
E.O. 14192. The AP1000 renewal and amendments will facilitate future 
reactor licensing by resolving design issues generically, which will 
lead to shorter and more efficient reviews yielding savings to the 
agency and future applicants.

D. Executive Order 14267: Reducing Anti-Competitive Regulatory Barriers

    E.O. 14267 requires the NRC to identify anti-competitive 
regulations for recission or modification. The purpose of a design 
certification rule is to facilitate the licensing process for future 
applicants that reference the certified design. Therefore, there are no 
anti-competitive regulatory barriers associated with this rule.

E. Executive Order 14270: Zero-Based Regulatory Budgeting To Unleash 
American Energy

    E.O. 14270, ``Zero-Based Regulatory Budgeting to Unleash American 
Energy,'' requires the NRC to insert a conditional sunset date into all 
new or amended NRC regulations provided the regulations are (1) 
promulgated under the Atomic Energy Act of 1954, as amended (AEA), the 
Energy Reorganization Act of 1974, as amended (ERA), or the Nuclear 
Waste Policy Act of 1982, as amended (NWPA); (2) not statutorily 
required; and (3) not part of the NRC's permitting regime. The NRC 
determined that the regulatory changes proposed in this rule are part 
of the NRC permitting regime as future licensing applicants may 
reference the AP1000 certified design to obtain operating licenses. 
Therefore, the NRC views this rulemaking to be outside the scope of 
E.O. 14270 and did not insert conditional sunset dates for the 
regulatory changes in this direct final rule.

VIII. Availability of Documents

    The documents identified in the following table are available to 
interested persons through one or more of the following methods, as 
indicated.

\1\ The regulatory history of the NRC's design certification reviews is
  a package of documents that is available in the NRC's Public Document
  Room and NRC Library: Reactor Regulatory History on Design
  Certification Rules, April 26, 2000. This history spans the period
  during which the NRC simultaneously developed the regulatory standards
  for reviewing these designs and the form and content of the rules that
  certified the designs. This document predates this rulemaking and
