SUPPLEMENTARY INFORMATION:

I. Discussion

    The NRC is issuing a new 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 
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.
    RG 1.250 was issued with a temporary identification of Draft 
Regulatory Guide, DG-1402 (ADAMS Accession No. ML22003A180).

II. Additional Information

    The NRC published a notice of the availability of DG-1402 in the 
Federal Register on March 18, 2022 (87 FR 15456) for a 30-day public 
comment period. The public comment period closed on April 18, 2022. 
Public comments on DG-1402 and the staff responses to the public 
comments are available under ADAMS under Accession No. ML22153A416.
    RG 1.250 endorses, with clarifications, Nuclear Energy Institute 
(NEI) 17-06, ``Guidance on Using IEC 61508 SIL Certification to Support 
the Acceptance of Commercial Grade Digital Equipment for Nuclear Safety 
Related Applications,'' Revision 1, issued December 2021 (ADAMS 
Accession No. ML21337A380).

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 1.250 describes a method that the NRC staff considers acceptable 
to implement regulatory requirements for dedication of commercial-grade 
I&C items as basic components. Issuance of this RG does not constitute 
backfitting as defined in Sec.  50.109 of title 10 of the Code of 
Federal Regulations (10 CFR) (the Backfit Rule); forward fitting as 
defined in Management Directive (MD) 8.4, ``Management of Backfitting, 
Forward Fitting, Issue Finality, and Information Requests;'' and does 
not affect the issue finality of any approval under 10 CFR part 52. As 
discussed in the ``Implementation'' section of this RG, the NRC has no 
intention to impose this RG as a new requirement.

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: October 27, 2022.

    For the Nuclear Regulatory Commission.
