NUCLEAR REGULATORY 
COMMISSION 
10 CFR Parts 50 and 52 
[NRC–2022–0143] 
Draft Regulatory Guide: Criteria for 
Programmable Digital Devices in Safety-Related Systems of Nuclear Power Plants 
AGENCY : Nuclear Regulatory 
Commission. 
ACTION : Proposed guide; request for 
comment. 
SUMMARY : The U.S. Nuclear Regulatory 
Commission (NRC) is issuing for public comment a draft regulatory guide (DG), DG–1374, ‘‘Criteria for Programmable Digital Devices in Safety-Related Systems of Nuclear Power Plants.’’ This DG is proposed Revision 4 of Regulatory Guide (RG) 1.152, ‘‘Criteria for Use of Computers in Safety Systems of Nuclear Power Plants.’’ DG–1374 describes an approach that is acceptable to the NRC staff to meet regulatory requirements for promoting high functional reliability, design quality, and a secure development and operational environment (SDOE) for the use of programmable digital devices (PDDs) in the safety-related systems of nuclear power generating stations. 
DATES : Submit comments by April 10, 
2023. 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:

B. Submitting Comments 
The NRC encourages electronic 
comment submission through the 
Federal rulemaking website (https://www.regulations.gov). Please include Docket ID NRC–2022–0143 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 agency’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 ‘‘Criteria for 
Programmable Digital Devices in Safety- Related Systems of Nuclear Power Plants,’’ is temporarily identified by its task number, DG–1374 (ADAMS Accession No. ML23012A242). 
This revision (Revision 4) of the guide 
endorses the Institute of Electrical and Electronic Engineers (IEEE) Standard (Std) 7–4.3.2–2016, ‘‘IEEE Standard Criteria for Programmable Digital Devices in Safety Systems of Nuclear 
VerDate Sep<11>2014 16:43 Mar 09, 2023 Jkt 259001 PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 E:\FR\FM\10MRP1.SGM 10MRP1lotter on DSK11XQN23PROD with PROPOSALS114958 Federal Register / Vol. 88, No. 47 / Friday, March 10, 2023 / Proposed Rules 
Power Generating Stations,’’ with some 
exceptions and clarifications. Specifically, this revision removes the previous SDOE guidance from this guide and instead endorses, with clarifications, the SDOE criteria within IEEE Std 7–4.3.2–2016. This revision also includes additional guidance for fault detection and self-diagnostics, if used, in Digital Instrumentation and Control systems. In addition, this revision endorses Annex D of IEEE Std 7–4.3.2–2016 and clarifies the applicability of the control of access guidance for safety-related PDDs. 
The staff is also issuing for public 
comment a draft regulatory analysis (ADAMS Accession No. ML22132A293). The staff developed a regulatory analysis to assess the value of issuing or revising a regulatory guide as well as alternative courses of action. 
As noted in the Federal Register on 
December 9, 2022 (87 FR 75671), this document is being published in the ‘‘Proposed Rules’’ section of the Federal Register to comply with publication 
requirements under 1 CFR chapter I. 
III. Backfitting, Forward Fitting, and 
Issue Finality 
If finalized, the NRC staff may use this 
DG as a reference in its regulatory processes, such as licensing, inspection, or enforcement. However, the NRC staff does not intend to use the guidance in this DG to support NRC staff actions in a manner that would constitute backfitting as that term is defined in Section 50.109 of title 10 of the Code of Federal Regulations (10 CFR), ‘‘Backfitting,’’ and as described in NRC Management Directive (MD) 8.4, ‘‘Management of Backfitting, Forward Fitting, Issue Finality, and Information Requests,’’ nor does the NRC staff intend to use the guidance to affect the issue finality of an approval under 10 CFR part 52, ‘‘Licenses, Certifications, and Approvals for Nuclear Power Plants.’’ The staff also does not intend to use the guidance to support NRC staff actions in a manner that constitutes forward fitting as that term is defined and described in MD 8.4. If a licensee believes that the NRC is using this regulatory guide in a manner inconsistent with the discussion in this Implementation section, then the licensee may file a backfitting or forward fitting appeal with the NRC in accordance with the process in Management Directive 8.4. 
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.
