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.

II. Additional Information

    Revision 3 of RG 1.21 was issued with a temporary identification of 
Draft Regulatory Guide (DG) 1377. The NRC published a notice of the 
availability of DG-1377 in the Federal Register on January 5, 2021, (86 
FR 326) for a 45-day public comment period. The public comment period 
closed on February 19, 2021. Public comments on DG-1377 and the staff 
responses to the public comments are available under ADAMS under 
Accession No. ML21132A226.

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

    Revision 3 of RG 1.21 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''; constitute forward fitting as 
that term is defined and described in MD 8.4; or affect the issue 
finality of any approval issued under 10 CFR part 52. As explained in 
Revision 3 of RG 1.21, applicants and licensees would not be required 
to comply with the positions set forth in the RG.
