SUPPLEMENTARY INFORMATION: 

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC) has issued for public 
comment a draft guide in the agency's Regulatory Guide Series. This 
series has been 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, entitled ``Qualification of Safety-
Related Battery Chargers & Inverters for Nuclear Power Plants,'' is 
temporarily identified by its task number, DG-1148, which should be 
mentioned in all related correspondence.
    The Commission's regulations in Title 10, Part 50, of the Code of 
Federal Regulations (10 CFR part 50), ``Domestic Licensing of 
Production and Utilization Facilities,'' require that structures, 
systems, and components that are important to safety in a nuclear power 
plant must be designed to accommodate the effects of environmental 
conditions [i.e., remain functional under postulated design-basis 
events (DBEs)]. Toward that end, the general requirements are contained 
in General Design Criteria 1, 2, 4, and 23 of Appendix A, ``General 
Design Criteria for Nuclear Power Plants,'' to 10 CFR part 50. 
Augmenting those general requirements, the specific requirements 
pertaining to qualification of certain electrical equipment important 
to safety are contained 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,'' to 10 CFR part 
50, requires that where a test program is used to verify the adequacy 
of a specific design feature, it should include suitable qualification 
testing of a prototype unit under the most severe DBE.
    This regulatory guide describes a method that the NRC considers 
acceptable for use in implementing specific parts of the agency's 
regulations for qualification of safety-related battery chargers and 
inverters for nuclear power plants.

II. Further Information

    The NRC is soliciting comments on Draft Regulatory Guide DG-1148. 
Comments may be accompanied by relevant information or supporting data,
