SUPPLEMENTARY INFORMATION:

I. Discussion

    The NRC is issuing a revision to an existing 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 1.91 was issued with a temporary identification of 
Draft Regulatory Guide (DG)-1388. The NRC published a notice of the 
availability of DG-1388 in the Federal Register on August 2, 2021, (86 
FR 41525) for a 30-day public comment period. The public comment period 
closed on September 1, 2021. Public comments on DG-1388 and the staff 
responses to the public comments are available in ADAMS under Accession 
No. ML21260A167.

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 1.91 does not constitute backfitting as defined in 
section 50.109 of title 10 of the Code of Federal Regulations, 
``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 any approval issued under 10 CFR part 52. As explained in 
Revision 3 of RG 1.91, applicants and licensees would not be required 
to comply with the positions set forth in the RG.

    For the Nuclear Regulatory Commission.
