NUCLEAR REGULATORY COMMISSION

[NRC-2026-0133]


Draft Regulatory Guide: Nuclear Power Plant Simulation Facilities 
for Use in Operator Training, License Examinations, and Applicant 
Experience Requirements

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft guide; request for comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for 
public comment draft regulatory guide (DG)-1384, ``Nuclear Power Plant 
Simulation Facilities for Use in Operator Training, License 
Examinations, and Applicant Experience Requirements.'' This DG is 
proposed Revision 5 of Regulatory Guide 1.149 of the same name. This 
proposed revision updates and clarifies the scope of the guideline to 
better serve simulation facility licensees and the regulatory 
community. On October 10, 2019, the American National Standards 
Institute (ANSI) approved ANSI/ANS 3.5 2018, ``Nuclear Power Plant 
Simulators for Use in Operator Training and Examination'' (Ref. 2), as 
an

[[Page 20185]]

American National Standard. The American Nuclear Society (ANS) 
Standards Committee Working Group ANS 3.5 developed and approved this 
industry consensus standard. The proposed revision to RG 1.149 endorses 
this standard.

DATES: Submit comments by May 15, 2026. Comments received after this 
date will be considered if it is practical to do so, but the NRC is 
able to ensure consideration only for comments received on or before 
this date.

ADDRESSES: You may submit comments by any of the following methods; 
however, the NRC encourages electronic comment submission through the 
Federal rulemaking website.
     Federal Rulemaking website: Go to https://www.regulations.gov and search for Docket ID NRC-2026-0133. Address 
questions about Docket IDs in Regulations.gov to Bridget Curran;

     NRC's PDR: The PDR, where you may examine and order copies 
of publicly available documents, is open by appointment. To make an 
appointment to visit the PDR, please send an email to

Federal holidays.

B. Submitting Comments

    The NRC encourages electronic comment submission through the 
Federal rulemaking website (https://www.regulations.gov). Please 
include Docket ID NRC-2026-0133 in your comment submission.
    The NRC cautions you not to include identifying or contact 
information that you do not want to be publicly disclosed in your 
comment submission. The NRC will post all comment submissions at 
https://www.regulations.gov as well as enter the comment submissions 
into ADAMS. The NRC does not routinely edit comment submissions to 
remove identifying or contact information.
    If you are requesting or aggregating comments from other persons 
for submission to the NRC, then you should inform those persons not to 
include identifying or contact information that they do not want to be 
publicly disclosed in their comment submission. Your request should 
state that the NRC does not routinely edit comment submissions to 
remove such information before making the comment submissions available 
to the public or entering the comment into ADAMS.

II. Additional Information

    The NRC is issuing for public comment a DG in the NRC's 
``Regulatory Guide'' series. This series was developed to describe 
methods that are acceptable to the NRC staff for implementing specific 
parts of the NRC's regulations, to explain techniques that the staff 
uses in evaluating specific issues or postulated events, and to 
describe information that the staff needs in its review of applications 
for permits and licenses.
    The DG, entitled ``Nuclear Power Plant Simulation Facilities for 
Use in Operator Training, License Examinations, and Applicant 
Experience Requirements,'' is temporarily identified by its task 
number, DG-1384 (ADAMS Accession No. ML21263A127).
    This guide helps to ensure that simulation facilities used to meet 
the requirements of part 55 of title 10 of the Code of Federal 
Regulations (10 CFR) are sufficient in both scope and fidelity for the 
regulatory purposes for which they are being used with respect to (1) 
operating tests, as described in 10 CFR 55.45(a), (2) licensed operator 
requalification training requirements, as described in 10 CFR 55.59, 
and (3) performance of control manipulations that affect reactivity to 
establish eligibility for an operator's license, as described in 10 CFR 
55.31(a)(5).
    The staff is also issuing for public comment a draft regulatory 
analysis (ADAMS Accession No. ML25337A053). The staff developed a 
regulatory analysis to assess the value of issuing an RG as well as an 
alternative course of action.

III. Backfitting, Forward Fitting, and Issue Finality

    The issuance of DG-1384, if finalized, would be proposed Revision 5 
to RG 1.149, which endorses industry guidance for use to ensure that 
simulation facilities are sufficient in scope and fidelity for 
regulatory purposes to meet NRC regulations in 10 CFR 55, ``Operators' 
Licenses.'' Issuance of DG-1384 in final form wouldnot constitute 
backfitting as defined in10 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. As 
explained in DG-1384, applicants or licensees generally would not be 
required to comply with the positions in DG-1384.

IV. Submitting Suggestions for Improvement of Regulatory Guides

    A member of the public may, at any time, submit suggestions to the 
NRC for improvement of existing RGs or for the development of new RGs. 
Suggestions can be submitted on the NRC's public website at https://www.nrc.gov/reading-rm/doc-collections/reg-guides/contactus.html. 
Suggestions will be

considered in future updates and enhancements to the ``Regulatory 
Guide'' series.

V. Executive Order (E.O.) 12866

    The Office of Information and Regulatory Affairs determined that 
this DG is not a significant regulatory action under E.O. 12866.
