NUCLEAR REGULATORY COMMISSION
10 CFR Parts 50 and 52
[NRC-2024-0140]
Draft Regulatory Guides: Criteria for Power Systems for Nuclear
Power Plants and Criteria for the Protection of Class 1E Power Systems
and Equipment for Nuclear Power Plants
AGENCY: Nuclear Regulatory Commission
ACTION: Draft guides; request for comment.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for
public comment two related draft Regulatory Guides (DGs) namely DG-
1420, ``Criteria for Power Systems for Nuclear Power Plants,'' and DG-
1354, ``Criteria for the Protection of Class 1E Power Systems and
Equipment for Nuclear Power Plants.'' DG-1420 is proposed Revision 4 to
Regulatory Guide (RG) 1.32 of the same name and DG-1354 is newly
proposed Revision 0 of RG 1.238. DG-1420 describes an approach that is
acceptable to the NRC staff to meet regulatory requirements for the
design, operation, and testing of electric power systems in nuclear
power plants. DG-1354 describes an approach that is acceptable to the
NRC staff for use in complying with NRC regulations that address the
protection of Class 1E power systems and equipment at nuclear power
plants.
DATES: Submit comments by September 27, 2024. Comments received after
this date will be considered if it is practical to do so, but the NRC
is able to ensure consideration only for comments received on or before
this date.
ADDRESSES: You may submit comments by any of the following methods;
however, the NRC encourages electronic comment submission through the

NRC's PDR: The PDR, where you may examine and order copies
of publicly available documents, is open by appointment. To make an
appointment to visit the PDR, please send an email to
[email protected] or call 1-800-397-4209 or 301-415-4737, between 8

B. Submitting Comments
The NRC encourages electronic comment submission through the
Federal rulemaking website (https://www.regulations.gov). Please
include Docket ID NRC-2024-0140 in your comment submission.
The NRC cautions you not to include identifying or contact
information that you do not want to be publicly disclosed in your
comment submission. The NRC will post all comment submissions at
https://www.regulations.gov as well as enter the comment submissions
into ADAMS. The NRC does not routinely edit comment submissions to
remove identifying or contact information.
If you are requesting or aggregating comments from other persons
for submission to the NRC, then you should inform those persons not to
include identifying or contact information that they do not want to be
publicly disclosed in their comment submission. Your request should
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. Additional Information
The NRC is issuing for public comment two DGs in the NRC's
``Regulatory Guide'' series namely DG-1354 and DG-1420. This series was
developed to describe methods that are acceptable to the NRC staff for
implementing specific parts of the agency's regulations, to explain
techniques that the staff uses in evaluating specific issues or
postulated events, and to describe information that the staff needs in
its review of applications for permits and licenses.
The DG, entitled ``Criteria for Power Systems for Nuclear Power
Plants,'' is temporarily identified by its task
[[Page 68788]]
number, DG-1420 (ADAMS Accession No. ML24158A060) and the DG, entitled,
``Criteria for the Protection of Class 1E Power Systems and Equipment
for Nuclear Power Plants,'' is temporarily identified by its task
number, DG-1354 (ADAMS Accession No. ML24158A041).
DG-1420 describes an approach that is acceptable to the NRC staff
to meet regulatory requirements for the design, operation, and testing
of electric power systems in nuclear power plants. DG-1420 endorses,
with exceptions and clarifications, the Institute of Electrical and
Electronics Engineers (IEEE) Standard (Std.) 308 2020, ``IEEE Standard
Criteria for Class 1E Power Systems for Nuclear Power Generating
Stations.'' In addition, DG-1420 includes the guidance provisions of RG
1.41, Revision 0, ``Preoperational Testing of Redundant On-Site
Electric Power Systems to Verify Proper Load Group Assignments,'' which
describes methods acceptable to the NRC for independence among
redundant, onsite power sources and their load groups as part of the
initial preoperational testing program and after major modifications or
repairs. The staff plans to withdraw RG 1.41 if DG-1420 is finalized as
RG 1.32, Revision 4.
DG-1354 describes an approach that is acceptable to the staff of
the NRC for use in complying with NRC regulations that address the
protection of Class 1E power systems and equipment at nuclear power
plants. DG-1354 endorses, with exceptions, additions and
clarifications, IEEE Std. 741-2022, ``IEEE Standard for Criteria for
the Protection of Class 1E Power Systems and Equipment for Nuclear
Power Generating Stations.''
The staff is also issuing for public comment the draft regulatory
analyses (ADAMS Accession Nos. ML24158A062 and ML24158A042). The staff
developed these regulatory analyses to assess the value of issuing or
revising the RGs as well as alternative courses of action.
As noted in the Federal Register on December 9, 2022 (87 FR 75671),
this document is being published in the ``Proposed Rules'' section of
the Federal Register to comply with publication requirements under
chapter I of title 1 of the Code of Federal Regulations (CFR).
III. Backfitting, Forward Fitting, and Issue Finality
If finalized, DG-1420 and DG-1354, would not constitute backfitting
as defined in 10 CFR 50.109, ``Backfitting,'' and as described in NRC
Management Directive (MD) 8.4, ``Management of Backfitting, Forward
Fitting, Issue Finality, and Information Requests''; affect issue
finality of any approval issued under 10 CFR part 52, ``Licenses,
Certificates, and Approvals for Nuclear Power Plants''; or constitute
forward fitting as defined in MD 8.4, because, as explained in these
DGs, licensees would not be required to comply with the positions set
forth in these DGs.
IV. Submitting Suggestions for Improvement of Regulatory Guides
A member of the public may, at any time, submit suggestions to the
NRC for improvement of existing RGs or for the development of new RGs.
Suggestions can be submitted on the NRC's public website at https://www.nrc.gov/reading-rm/doc-collections/reg-guides/contactus.html.
Suggestions will be considered in future updates and enhancements to
the ``Regulatory Guide'' series.
