NUCLEAR REGULATORY COMMISSION
[NRC-2020-0279]
Application and Testing of Safety-Related Diesel Generators in
Nuclear Power Plants
AGENCY: Nuclear Regulatory Commission.
ACTION: Draft regulatory guide; request for comment.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for
public comment draft regulatory guide (DG), DG-1303, ``Application and
Testing of Safety-Related Diesel Generators in Nuclear Power.'' This
draft guide is proposed revision 5 of Regularity Guide (RG) 1.9. DG-
1303 provides updated guidance that the staff of the NRC considers
acceptable to demonstrate
[[Page 5268]]
compliance with the NRC regulations for safety-related alternating
current (AC) power supplies intended for use as onsite emergency power
sources in nuclear power plants. This revision of RG 1.9 would endorse,
with supplements and clarifications, Institute of Electrical and
Electronics Engineers (IEEE) Std 387-2017, ``IEEE Standard for Criteria
for Diesel Generator Units Applied as Standby Power Supplies for
Nuclear Power Generating Stations'' and IEEE Std 2420-2019, ``IEEE
Standard for Combustion Turbine Generator Units Applied as Standby
Power Supplies for Nuclear Power Generating Stations.'' This guidance
would help ensure that the standby emergency power supplies are
qualified, have sufficient capacity, and have the necessary reliability
and availability for design-basis events.
DATES: Submit comments by February 18, 2021. 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. Although a time limit is given, comments and suggestions in
connection with items for inclusion in guides currently being developed
or improvements in all published guides are encouraged at any time.
ADDRESSES: You may submit comments by any of the following methods;
however, the NRC encourages electronic comment submission through the
Federal Rulemaking website:

SUPPLEMENTARY INFORMATION:
I. Obtaining Information and Submitting Comments
A. Obtaining Information
Please refer to Docket ID NRC-2020-0279 when contacting the NRC
about the availability of information regarding this action. You may
obtain publicly available information related to this action, by any of
the following methods:
Federal Rulemaking Website: Go to https://www.regulations.gov and search for Docket ID NRC-2020-0279.
NRC's Agencywide Documents Access and Management System
(ADAMS): You may obtain publicly available documents online in the
ADAMS Public Documents collection at https://www.nrc.gov/reading-rm/adams.html. To begin the search, select ``Begin Web-based ADAMS
Search.'' For problems with ADAMS, please contact the NRC's Public
Document Room (PDR) reference staff at 1-800-397-4209, 301-415-4737, or
by email to [email protected].
Attention: The PDR, where you may examine and order copies
of public documents, is currently closed. You may submit your request
to the PDR via email at [email protected] or call 1-800-397-4209 or
301-415-4737, between 8:00 a.m. and 4:00 p.m. (EST), Monday through
Friday, except Federal holidays.
B. Submitting Comments
The NRC encourages electronic comment submission through the
Federal Rulemaking website (https://www.regulations.gov). Please
include Docket ID NRC-2020-0279 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 posts all comment submissions at https://www.regulations.gov/ as well as enters 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 submissions into ADAMS.
II. Additional Information
The NRC is issuing for public comment a draft regulatory guide in
the NRC's ``Regulatory Guide'' series. This series was developed to
describe methods that are acceptable to the NRC staff for implementing
specific parts of the NRC'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.
This DG titled, ``Application and Testing of Safety-Related Diesel
Generators in Nuclear Power Plants,'' is identified by its temporary
task number, DG-1303. The draft guide is proposed revision 5 of RG 1.9
of the same name (ADAMS Accession No. ML14281A071). This DG provides
updated guidance for actions and information that is needed for
licensees, applicants, and combined operating license (COL) holders to
meet the NRC regulations for safety-related standby AC power supplies
intended for use as onsite emergency power sources in nuclear power
plants. Information provided in this DG may be used by NRC staff,
applicants, COLs holders, and licensees. This guidance helps ensure
that the emergency standby AC power supplies are qualified, have
sufficient capacity, and have the necessary reliability and
availability for design-basis events.
The staff is also issuing for public comment a draft regulatory
analysis (ADAMS Accession No. ML14297A097). The staff develops a
regulatory analysis to assess the value of issuing or revising a
regulatory guide as well as alternative courses of action.
III. Backfitting, Forward Fitting, and Issue Finality
DG-1303, if finalized, would revise RG 1.9, revision 4, which
describes methods acceptable to the NRC staff for complying with the
NRC's regulations for safety-related standby AC power supplies intended
for use as onsite emergency power sources in nuclear power plants.
Issuance of DG-1303, if finalized, would not constitute backfitting
as defined in section 50.109 of title 10 of the Code of Federal
Regulations (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''; constitute forward
fitting as that term is defined and described in MD 8.4; or affect the
[[Page 5269]]
issue finality of any approval issued under 10 CFR part 52. As
explained in DG-1303, applicants and licensees would not be required to
comply with the positions set forth in DG-1303.
