Risk-Informed, Technology-Inclusive Regulatory Framework for
Advanced Reactors; Correction
AGENCY: Nuclear Regulatory Commission.
ACTION: Final rule; correction.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is correcting a
final rule that was published in the Federal Register (FR) on March 30,
2026, regarding the amendment of the NRC's regulations to add a risk-
informed, performance-based, and technology-inclusive regulatory
framework for commercial nuclear plants in response to the Nuclear
Energy Innovation and Modernization Act. This action is necessary to
correct errors in the final rule and address conflicting amendatory
instructions between this final rule and the ``Categorical Exclusions
From Environmental Review'' final rule also published on March 30,
2026.
DATES: The correction is effective on April 29, 2026.

SUPPLEMENTARY INFORMATION: The final rule, ``Risk-Informed, Technology-
Inclusive Regulatory Framework for Advanced Reactors'' (RIN 3150-AK31;
NRC-2019-0062), (91 FR 15696; March 30, 2026) contained some minor
errors in the regulatory instructions for Sec. Sec. 20.1002, 20.1401,
and 53.020 that this document corrects. In addition, on the same date,
the final rule, ``Categorical Exclusions From Environmental Review''
(RIN 3150-AK54; NRC-2018-0030), (91 FR 15519; March 30, 2026) expanded
and reorganized Sec. 51.22. The final rules contained conflicting
amendatory instructions for Sec. 51.22. This document corrects the
amendatory instructions for Sec. 51.22 in FR Doc. 2026-06048 to
include the references to 10 CFR part 53 that remain applicable
following the reorganization of the affected provisions of Sec. 51.22
in the final rule, ``Categorical Exclusions From Environmental
Review.''
This document corrects errors in the preamble and in amendatory
instructions 54, 57.a, 114, and 133 for Sec. Sec. 20.1002, 20.1401,
51.22 and the addition of part 53, respectively. Amendatory
instructions 54 and 57.a repeated the word ``under'' so this document
revises those amendatory instructions by removing the extra word.
Amendatory instruction 114 of 91 FR 15696 conflicts with amendatory
instruction 4 of 91 FR 15519. This document revises amendatory
instruction 114 to include the appropriate references to 10 CFR part
53, after Sec. 51.22 was revised and republished by 91 FR 15519. This
document revises the definition of ``Construction'' in Sec. 53.020 in
amendatory instruction 133 to correct a spelling mistake. Finally, this
document also corrects the preamble discussion of anticipated event
sequences, unlikely event sequences, and very unlikely event sequences
to add a superscript negative sign in front of the five instances of
exponents.
Corrections
In the FR on March 30, 2026, in FR Doc. 2026-06048, beginning on
page 15696, the NRC makes the following corrections:
Preamble
1. On page 15702, in the first column, lines 5-17 are corrected to
read as follows: ``mean frequencies of 1x10-2/plant-year and
greater are classified as anticipated event sequences. Within the LMP
methodology, infrequent event sequences with mean frequencies of
1x10-4/plant-year to 1x10-2/plant-year are
classified as unlikely event sequences. ``Very unlikely event
sequences'' are less likely to occur than unlikely event sequences.
Within the LMP methodology, rare event sequences with frequencies of
5x10-7/plant-year to 1x10-4/plant-year are
classified as''.
