NUCLEAR REGULATORY COMMISSION
10 CFR Parts 50 and 52
[NRC-2022-0083]
Qualification of Connection Assemblies for Production and Utili zation Facilities
AGENCY: Nuclear Regulatory Commission.
ACTION: Regulatory guide; issuance.
SUMMARY
- The U.S. Nuclear Regulatory Commission (NRC) is issuing Revi sion 2 of
Regulatory Guide (RG) 1.156, Qualification of Connection Assem blies for Production
and Utilization Facilities. This revised guide was updated to endorse Institute of
Electrical and Electronics Engineers Std. 572-2019 to provide the latest technical
information on approaches to satisfy the qualification requirem ents for connection
assemblies. This includes guidance that when used in conjuncti on with the guidance in
RG 1.89, Environmental Qualification of Certain Electric Equip ment Important to Safety
for Nuclear Power Plants, provides an acceptable method of dem onstrating compliance
with the NRC regulations pertaining to the environmental qualif ication of connectors,
terminations, and environmental seals in combination with cable s or wires as assemblies
for service in production and utilization facilities to ensure that the connection
assemblies can perform their safety functions. Further, the re vised guide modifies the
title of the RG to include other nuclear facilities, as discuss ed in the RG Section A, under
Applicability.
DATES: Revision 2 of RG 1.156 is available on February 13, 2023.

SUPPLEMENTARY INFORMATION:
I. Discussion
The NRC is issuing a revision to an existing guide in the NRCs Regulatory
Guide series. This series was developed to describe methods t hat are acceptable to
the NRC staff for implementing specific parts of the agencys r egulations, 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 appl ications for permits and
licenses.
The proposed Revision 2 of RG 1.156 was issued with a temporary identification
number of DG-1400 (ADAMS Accession No. ML21288A562).
Revision 2 of RG 1.156 describes basic procedures for qualifyin g connection
assemblies (e.g., connectors, terminations, and environmental s eals in combination with
related cables or wires as assemblies). The qualification requ irements in this standard,
when used in conjunction with RG 1.89 (ADAMS Accession No. ML00 3740271) allow an
applicant or licensee to demonstrate and document the ability o f the equipment to
perform safety functions under applicable service conditions, i ncluding design-basis
events. Additionally, Revision 2 of RG 1.156 modifies the titl e of the RG to include other
nuclear facilities, as discuss in the RG Section A, under Appli cability.
II. Additional Information
In January 2017 the staff conducted a periodic review of Revisi on 1 to RG 1.156,
and on January 17, 2017, the staff reported the results of the periodic review, Results of
Periodic Review of Regulatory Guide 1.156, (ADAMS Package Acce ssion No.
3 ML16350A346). Based on the results of the periodic review, the staff concluded that
there were no technical issues for staff to address related to the periodic review of
RG 1.156, Revision 1, and no changes to RG 1.156, Revision 1, w ere warranted.
The NRC published a notice of availability of DG-1400 in the Federal Register on
April 11, 2022 (87 FR 21221) for a 30-day public comment period. The public comment
period ended May 11, 2022. Public comments and staff responses to those comments
are available in ADAMS under Accession No. ML22224A053.
As noted in the Federal Register on December 9, 2022 (87 FR75671), this
document is being published in the Rules section of the Federal Register to comply
with publication requirements under 1 CFR chapter I.
III. Congressional Review Act
This RG is a rule as defined in the Congressional Review Act (5 U.S.C. 801-808).
However, the Office of Management and Budget has not found it t o be a major rule as
defined in the Congressional Review Act.
IV. Backfitting, Forward Fitting, and Issue Finality
The issuance of this regulatory guide does not constitute backf itting as defined in
section 50.109 of title 10 of the Code of Federal Regulations (10 CFR), Backfitting, and
as described in NRC Management Directive 8.4, Management of Ba ckfitting, Forward
Fitting, Issue Finality, and Information Requests, or affect i ssue finality of any approval
issued under 10 CFR part 52, Licenses, Certificates, and Appro vals for Nuclear Power
Plants, because, as explained in this regulatory guide, licens ees are not required to
comply with the positions set forth in this regulatory guide.
V. 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
4 submitted on the NRCs public website at https://www.nrc.gov/re ading-rm/doc-
collections/reg-guides/contactus.html. Suggestions will be con sidered in future updates
and enhancements to the Regulatory Guide series.
