SUPPLEMENTARY INFORMATION: 

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC) 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 
Continuous Duty Safety-Related Motors for Nuclear Power Plants,'' is 
temporarily identified by its task number, DG-1150, which should be 
mentioned in all related correspondence. DG-1150 is proposed Revision 1 
of Regulatory Guide 1.40, dated March 1973.
    This regulatory guide 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. Augmenting those general requirements 
are the specific requirements pertaining to qualification of certain 
electrical equipment important to safety that 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 conditions.

II. Further Information

    The NRC staff is soliciting comments on DG-1150. Comments may be 
accompanied by relevant information or supporting data and should 
mention DG-1150 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). Requests for technical information about DG-1150 may be 
directed to the NRC contact, Satish Aggarwal at (301) 251-7627 or e-
mail to [email protected].
    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 comments to remove any 
identifying or contact information, and therefore, they should not 
include any information in their comments that they do not want 
publicly disclosed. You may submit comments by any of the following 
methods:
    1. Mail comments to: Rulemaking and Directives Branch, Mail Stop: 
TWB-05-B01M, Office of Administration, U.S. Nuclear Regulatory 
Commission, Washington, DC 20555-0001.
    2. Federal e-Rulemaking Portal: Go to http://www.regulations.gov

Administration, U.S. Nuclear Regulatory Commission at (301) 492-3446.
    Comments would be most helpful if received by October 30, 2009. 
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.
    Electronic copies of DG-1150 are available through the NRC's public 
Web site under Draft Regulatory Guides in the ``Regulatory Guides'' 
collection of the NRC's Electronic Reading Room at http://www.nrc.gov/reading-rm/doc-collections/. Electronic copies are also available in 
ADAMS (http://www.nrc.gov/reading-rm/adams.html ), under Accession No. 
ML091200454.
    In addition, regulatory guides are available for inspection at the 
NRC's Public Document Room (PDR) located at 11555 Rockville Pike, 
Rockville, Maryland. The PDR's mailing address is USNRC PDR,
