SUPPLEMENTARY INFORMATION:
I. Background
On December 19, 2025, the NRC published a notice in the Federal
Register for a 60-day public comment period (90 FR 59402). The proposed
rule would amend the regulations by the incorporation by reference of
Institute of Electrical and Electronics Engineers Standard (IEEE Std)
603-2018 into title 10 of the Code of Federal Regulations (10 CFR)
50.55a, ``Codes and standards,'' and to provide for its use for nuclear
power reactors of all types. This proposed rule also includes a
conforming amendment to paragraph (b)(1)(v) of section 50.69, ``Risk-
informed categorization and treatment of structures, systems and
components for nuclear power reactors,'' of 10 CFR, which would extend
that provision to allow risk-informed alternatives to Clauses 5.3 and
5.4 of IEEE 603-2018 for certain systems, structure, and components.
II. Public Meeting
The NRC staff plans to hold the public meeting on February 3, 2026,
during the planned, 60-day public comment period to present an overview
of the proposed to amend its regulations to incorporate by reference
the Institute of Electrical and Electronics Engineers (IEEE) Standard
(Std) 603-2018, ``IEEE Standard Criteria for Safety Systems for Nuclear
Power Generating Stations'' and the accompanying DG-1251, Revision 1,
``Guidance for the Power, Instrumentation, and Control Portions of
Safety Systems for Nuclear Power Plants.''
Interested stakeholders may attend via telephone or online seminar.
The public meetings will be transcribed and will include a presentation
of the contents of the proposed rule and draft guidance; and an
opportunity for government agencies, organizations, and individuals to
ask questions. No comments on the proposed rule or draft guide will be
accepted during the meeting. Persons interested in attending this
meeting should monitor the NRC's Public Meeting Schedule web page at
<a href="https://www.nrc.gov/pmns/mtg">https://www.nrc.gov/pmns/mtg</a> for additional information, agendas for
the meeting, and access information for the meeting.
