SUPPLEMENTARY INFORMATION:

I. Discussion

    NUREG-1022, Revision 3, ``Event Reporting Guidelines: 10 CFR 50.72 
and 50.73,'' issued January 2013 (ADAMS Accession No. ML13032A220), 
contains guidelines that the staff of the NRC considers acceptable for 
use in meeting the reporting requirements in section 50.72 of title 10 
of the Code of Federal Regulations (10 CFR), ``Immediate notification 
requirements for operating nuclear power reactors,'' and 10 CFR 50.73, 
``Licensee event report system.'' In August 2018, the Nuclear Energy 
Institute submitted a petition for rulemaking to amend 10 CFR 50.72 
(ADAMS Accession No. ML18247A204). In 2021, the Commission directed the 
NRC staff to pursue the rulemaking (ADAMS Accession No. ML21209A953). 
As part of this rulemaking effort, the NRC determined that 
clarifications to the guidance in section 3.2.4, ``Degraded or 
Unanalyzed Condition,'' of NUREG 1022, Revision 3, could address part 
of the concerns identified in the petition. In developing draft 
Supplement 2 to NUREG 1022, Revision 3, the NRC

[[Page 80269]]

evaluated data on submitted and retracted events and held a public 
meeting on August 9, 2023 (ADAMS Accession No. ML23270B927), to discuss 
section 3.2.4 of NUREG 1022 with stakeholders.
    The NRC published a notice in the Federal Register on April 17, 
2024 (89 FR 27463) requesting public comment on draft Supplement 2 to 
NUREG 1022, Revision 3 (ADAMS Package Accession No. ML24036A109). The 
public comment period closed on June 17, 2024. The NRC received two 
public comments. The public comments and the NRC staff's responses are 
presented in a comment resolution memo available in ADAMS under 
Accession No. ML24197A131.
    NUREG-1022, Revision 3, Supplement 2 (ADAMS Accession No. 
ML24191A376), provides updated guidance for nuclear power reactor 
licensees and can be used for evaluating and reporting degraded or 
unanalyzed conditions as described in 10 CFR 50.72(b)(3)(ii) and 10 CFR 
50.73(a)(2)(ii). The specific guidance included in Supplement 2 
supersedes the guidance found in section 3.2.4 of NUREG-1022, Revision 
3.

II. Backfitting, Forward Fitting, and Issue Finality

    Issuance of NUREG-1022, Revision 3, Supplement 2, 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''; affect issue finality of any approval issued under 10 CFR 
part 52, ``Licenses, Certificates, and Approvals for Nuclear Power 
Plants''; or constitute forward fitting as defined in MD 8.4, because 
licensees are not required to comply with the guidance in Supplement 2.

III. Congressional Review Act

    NUREG-1022, Revision 3, Supplement 2, 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.

    Dated: September 26, 2024.
