SUPPLEMENTARY INFORMATION:

I. Discussion

    The NRC is issuing a new guide in the NRC's ``Regulatory Guide'' 
series. This series was developed to describe and make available to the 
public information regarding methods that are acceptable to the NRC 
staff for implementing specific parts of the agency's regulations, 
techniques that the NRC staff uses in evaluating specific issues or 
postulated events, and data that the NRC staff needs in its review of 
applications for permits and licenses.
    RG 1.243 was issued with a temporary identification of Draft 
Regulatory Guide, DG-1304.

II. Additional Information

    The NRC published a notice of the availability of DG-1304 in the 
Federal Register on February 10, 2021 (86 FR 8928) for a 45-day public 
comment period. The public comment period closed on March 29, 2020. 
Public comments on DG-1304 and the staff responses to the public 
comments are available in ADAMS under Accession No. ML21089A033.

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

    Issuance of this RG does not constitute backfitting as defined in 
section 50.109 of title 10 of the Code of Federal Regulations (10 CFR), 
``Backfitting,'' and as described in NRC Management Directive 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 issue finality of any 
approval issued under 10 CFR part 52, ``Licenses, Certificates, and 
Approvals for Nuclear Power Plants.'' As explained in this regulatory 
guide, applicants and licensees are not required to comply with the 
positions set forth in this regulatory guide.

    Dated: August 31, 2021.
