SUPPLEMENTARY INFORMATION:

I. Discussion

    The NRC is issuing a revision 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 proposed Revision 1 to RG 1.210 was issued with a temporary 
identification of Draft Regulatory Guide, DG-1412. This revision 
endorses, with clarifications, the Institute of Electrical and 
Electronic Engineers (IEEE) Standard (Std.) 650-2017, ``IEEE Standard 
for Qualification of Class 1E Static Battery Chargers, Inverters, and 
Uninterruptible Power Supply Systems for Nuclear Power Generating 
Stations.''

II. Additional Information

    The NRC published notice of the availability of DG-1412 in the 
Federal Register on February 1, 2023 (88 FR 6672) for a 30-day public 
comment period. The public comment period closed on March 3, 2023. 
Public comments on DG-1412 and the staff responses to the public 
comments are available in ADAMS under Accession No. ML23202A244.
    As noted in the Federal Register on December 9, 2022 (87 FR 75671), 
this document is being published in the ``Rules'' section of the 
Federal Register to comply with publication requirements under chapter 
I of title 1 the Code of the Federal Register (CFR).

III. Congressional Review Act

    This RG is a rule as defined in the Congressional Review Act (5 
U.S.C. 801-808). However, the Office of Management and Budget has not 
found it to be a major rule as defined in the Congressional Review Act.

IV. Backfitting, Forward Fitting, and Issue Finality

    RG 1.210, Revision 1, does 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''; does not constitute forward 
fitting as that term is defined and described in MD 8.4; and does not 
affect the issue finality of an approval issued under 10 CFR part 52. 
As explained in RG 1.210, applicants and licensees are not required to 
comply with the positions set forth in this RG.

V. 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.

    Dated: June 6, 2024.
