SUPPLEMENTARY INFORMATION: 

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC or Commission) is 
issuing for public comment a draft guide in the agency's ``Regulatory 
Guide'' series. This series was developed to describe and make 
available to the public such information as methods that are acceptable 
to the NRC staff for implementing specific parts of the NRC'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.
    The draft regulatory guide (DG), entitled ``Qualification of 
Connection Assemblies for Nuclear Power Plants,'' is temporarily 
identified by its task number, DG-1254, which should be mentioned in 
all related correspondence. DG-1254 is proposed Revision 1 of 
Regulatory Guide 1.156, dated November 1987.
    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.
    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,'' 
requires, in part, that test programs used to verify the adequacy of 
specific design features include suitable qualification testing of a 
prototype unit under the most adverse design conditions.
    In 10 CFR 50.49, ``Environmental Qualification of Electric 
Equipment Important to Safety for Nuclear Power Plants,'' the NRC 
requires that certain electric equipment important to safety be 
qualified for its application and specified performance. The regulation 
also identifies requirements for establishing environmental 
qualification methods and qualification parameters.

II. Further Information

    The NRC staff is soliciting comments on DG-1254. Comments may be 
accompanied by relevant information or supporting data and should 
mention DG-1254 in the subject line. Comments submitted in writing or 
in electronic form will be made available to the public in their 
entirety through the NRC's Agencywide Documents Access and Management 
System (ADAMS).
    Comments would be most helpful if received by April 27, 2011. 
Comments received after that 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. Although a time limit is given, 
comments and suggestions in connection with items for inclusion in 
guides currently being developed or improvements in all published 
guides are encouraged at any time.

ADDRESSES: You may submit comments by any one of the following methods. 
Please include Docket ID NRC-2011-0046 in the subject line of your 
comments. Comments submitted in writing or in electronic form will be 
posted on the NRC Web site and on the Federal rulemaking Web site 
Regulations.gov. Because your comments will not be edited to remove any 
identifying or contact information, the NRC cautions you against 
including any information in your submission that you do not want to be 
publicly disclosed.
    The NRC requests that any party soliciting or aggregating comments 
received from other persons for submission to the NRC inform those 
persons that the NRC will not edit their
