I. Introduction

    The U.S. Nuclear Regulatory Commission (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 1.40, ``Qualification of Continuous 
Duty Safety-Related Motors for Nuclear Power Plants,'' was issued with 
a temporary identification as Draft Regulatory Guide DG-1150.
    This RG describes a method that the staff of the NRC deems 
acceptable for complying with the Commission's regulations for 
qualification of continuous duty safety-related motors for nuclear 
power plants.
    The Commission's regulations in Title 10, Part 50, ``Domestic 
Licensing of Production and Utilization Facilities,'' of the Code of 
Federal Regulations (10 CFR part 50), require that structures, systems, 
and components in a nuclear power plant that are important to safety be 
designed to accommodate the effects of environmental conditions (i.e., 
they must remain functional under postulated design-basis events). 
Toward that end, General Design Criteria 1, 2, 4, and 23 of Appendix A, 
``General Design Criteria for Nuclear Power Plants,'' to 10 CFR Part 50 
contain the general requirements. The specific requirements pertaining 
to qualification of certain electrical equipment important to safety 
appear in 10 CFR 50.49, ``Environmental Qualification of Electric 
Equipment Important to Safety for Nuclear Power Plants.'' In addition, 
Criterion III, ``Design Control,'' of Appendix B, ``Quality Assurance 
Criteria for Nuclear Power Plants and Fuel Reprocessing Plants,'' to 10 
CFR part 50, requires that test programs, when used to verify the 
adequacy of a specific design feature, should include suitable 
qualification testing of a prototype unit under the most adverse design 

II. Further Information

    In August 2009, DG-1150 was published with a public comment period 
of 60 days from the issuance of the guide. The public comment period 
closed on October 30, 2009. The staff's responses to the comments 
received are located in the NRC's Agencywide Documents Access and 
Management System under accession number ML093080126. Electronic copies 
of RG 1.40, Revision 1 are available through the NRC's public Web site 
under ``Regulatory Guides'' at http://
