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of the contents of the proposed rule and draft guidance; and an 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 
https://www.nrc.gov/pmns/mtg for additional information, agendas for 
the meeting, and access information for the meeting.
    If special equipment or accommodations are needed to attend or 
present information at a public meeting, please contact Denise Edwards, 
telephone: 301-415-7204, email: [email protected], no later than 
10 days before the meeting to provide the NRC staff adequate notice to 
determine whether the request can be accommodated.
