NUCLEAR REGULATORY COMMISSION

[NRC-2011-0046]


Qualification of Connection Assemblies for Nuclear Power Plants

AGENCY: Nuclear Regulatory Commission.

ACTION: Regulatory guide; issuance.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or the Commission) 
is issuing a revision to Regulatory Guide (RG) 1.156, ``Qualification 
of Connection Assemblies for Nuclear Power Plants.'' This guide 
describes a method that the NRC considers acceptable for complying with 
the Commission's regulations on the environmental qualification of 
connection assemblies and environmental seals in combination with 
cables or wires as assemblies for service in nuclear power plants. The 
environmental qualification helps ensure that connection assemblies can 
perform their safety functions during and after a design-basis event.

SUPPLEMENTARY INFORMATION:

I. Introduction

    The NRC is issuing a revision to an existing guide in the agency's 
``Regulatory Guide'' series. This series was developed to describe and 
make available to the public information such as methods that are 
acceptable to the NRC staff for implementing specific parts of the 
agency's regulations, techniques that the staff uses in evaluating 
specific problems or postulated accidents, and data that the staff 
needs in its review of applications for permits and licenses.
    Revision 1 of Regulatory Guide 1.156, ``Qualification of Connection 
Assemblies for Nuclear Power Plants,'' was issued with a temporary 
identification as Draft Regulatory Guide, DG-1254.
    This guide provides information that supports Title 10 of the Code 
of Federal Regulations, part 50, ``Domestic Licensing of Production and 
Utilization Facilities'' (10 CFR Part 50), Appendix B, ``Quality 
Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing 
Plants,'' Criterion III, ``Design Control,'' and 10 CFR 50.49, 
``Environmental Qualification of Electric Equipment Important to Safety 
for Nuclear Power Plants.''

II. Further Information

    DG-1254 was published in the Federal Register (76 FR 10917) 
February 28, 2011, for a 60-day public comment period. The public

comments on DG-1254 are available under ML111730478.
