B. Submitting Comments

    The NRC encourages electronic comment submission through the 
Federal rulemaking website (https://www.regulations.gov). Please 
include Docket ID NRC 2022-0039 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

    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 ``Dedication of Commercial-Grade Digital 
Instrumentation and Control Items for Use in Nuclear Power Plants,'' is 
temporarily identified by its task number, DG-1402 (ADAMS Accession No. 
ML22003A180).
    The staff is also issuing for public comment a draft regulatory 
analysis (ADAMS Accession No. ML22003A181) for DG-1402. The staff 
developed the regulatory analysis to assess the value of issuing DG-
1402 as well as alternative courses of action.
    The draft guide is a proposed new regulatory guide for the 
dedication of commercial-grade digital I&C items for use in nuclear 
power plant safety applications. It endorses, with clarifications, 
Nuclear Energy Institute 17-06, ``Guidance on Using IEC 61508 SIL 
Certification to Support the Acceptance of Commercial Grade Digital

[[Page 15457]]

Equipment for Nuclear Safety Related Applications,'' Revision 1, issued 
December 2021 (ADAMS Accession No. ML21337A380), to supplement existing 
guidance.

III. Backfitting, Forward Fitting, and Issue Finality

    The NRC staff may use this regulatory guide as a reference in its 
regulatory processes, such as licensing, inspection, or enforcement. 
However, the NRC staff does not intend to use the guidance in this 
regulatory guide to support NRC staff actions in a manner that would 
constitute backfitting as that term is defined in Section 50.109 of 
title 10 of the Code of Federal Regulations (10 CFR), ``Backfitting,'' 
and as described in NRC Management Directive (MD) 8.4, ``Management of 
Backfitting, Forward Fitting, Issue Finality, and Information 
Requests,'' nor does the NRC staff intend to use the guidance to affect 
the issue finality of an approval under 10 CFR part 52. The staff also 
does not intend to use the guidance to support NRC staff actions in a 
manner that constitutes forward fitting as that term is defined and 
described in MD 8.4. If a licensee believes that the NRC is using this 
regulatory guide in a manner inconsistent with the discussion in this 
Implementation section, then the licensee may file a backfitting or 
forward fitting appeal with the NRC in accordance with the process in 
MD 8.4.

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.htm. 
Suggestions will be considered in future updates and enhancements to 
the ``Regulatory Guide'' series.
