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

    RG 1.29, Revision 6 corrects a minor error in the numbering within 
the Section C, ``Staff Regulatory Guidance.'' What was C.1.i became 
C.2. This results in C.2 becoming C.3 and C.3 became C.4. In addition, 
RG 1.29 was reformatted to conform with the current template for 
Regulatory Guides.

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 and Issue Finality

    Issuance of RG 1.29 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 (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 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 would not be required to comply with 
the positions set forth in this RG.

    Dated: July 27, 2021.
