NUCLEAR REGULATORY COMMISSION

10 CFR Parts 50 and 52

[NRC-2024-0019]


Draft Regulatory Guide: Installation Design and Installation of 
Vented Lead-Acid Storage Batteries for Production and Utilization 
Facilities

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft guide; request for comment.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for 
public comment a draft Regulatory Guide (DG), DG-1421, ``Installation 
Design and Installation of Vented Lead-Acid Storage Batteries for 
Production and Utilization Facilities.'' This DG is proposed Revision 3 
of Regulatory Guide 1.128, ``Installation Design and Installation of 
Vented Lead-Acid Storage Batteries for Nuclear Power Plants,'' and 
provides methods acceptable to the NRC to meet regulatory requirements 
for the installation design and installation of vented lead-acid 
storage batteries in production and utilization facilities. It 
endorses, with clarifications, the Institute of Electrical and 
Electronics Engineers (IEEE) Standard (Std.) 484-2019, ``IEEE 
Recommended Practice for Installation Design and Installation of Vented 
Lead-Acid Batteries for Stationary Applications.''

DATES: Submit comments by February 7, 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

B. Submitting Comments

    The NRC encourages electronic comment submission through the 
Federal rulemaking website (https://www.regulations.gov). Please 
include Docket ID NRC-2024-0019 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 a DG 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 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 ``Installation Design and Installation of Vented 
Lead-Acid Storage Batteries for Production and Utilization 
Facilities,'' is temporarily identified by its task number, DG-1421 
(ADAMS Accession No. ML23277A276).
    This revision of the guide (Revision 3) endorses, with 
clarifications, IEEE Std. 484-2019 and applies to production and 
utilization facilities licensed under part 50 and part 52 of title 10 
of the Code of Federal Regulations (10 CFR) within the scope of this 
RG. The previous version of this RG (ADAMS Accession No. ML070080013) 
endorsed, with certain clarifications, IEEE Std. 484-2002. In 2019, the 
IEEE revised IEEE Std. 484 to add information on thermal factors of 
influence (exposure temperature, ambient temperature, temperature 
gradient, and rate of temperature change) and safety provisions (e.g., 
electrical hazards, shock hazards, ground fault hazards, arc flash 
hazards, chemical hazards), modifications to the personal protective 
equipment section, major changes to mounting and ventilation sections, 
new provisions on connection to direct current systems and spare cells, 
and new provisions for material handling and hazard assessment, as well 
as many other updates, corrections, and clarifications to various 
sections. The revised IEEE standard also provides two new normative 
annexes.

[[Page 896]]

    The staff is also issuing for public comment a draft regulatory 
analysis (ADAMS Accession No. ML23277A279). The staff developed a 
regulatory analysis to assess the value of issuing or revising a 
regulatory guide 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 1 
CFR chapter I.

III. Backfitting, Forward Fitting, and Issue Finality

    Issuance of DG-1421, if finalized, 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 the issue 
finality of an approval issued under 10 CFR part 52, ``Licenses, 
Certifications, and Approvals for Nuclear Power Plants''; or constitute 
forward fitting as that term is defined and described in MD 8.4, 
because, as explained in this DG, licensees would not be required to 
comply with the positions set forth in this DG.

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.
