SUPPLEMENTARY INFORMATION: The U.S. Nuclear Regulatory Commission (NRC) 
is issuing the new Regulatory Guide 1.210, ``Qualification of Safety-
Related Battery Chargers and Inverters for Nuclear Power Plants.'' The 
NRC's regulatory guides 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.
    The 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 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 appear in General Design 
Criterion (GDC) 1, ``Quality Standards and Records,'' GDC 2, ``Design 
Bases for Protection Against Natural Phenomena,'' GDC 4, 
``Environmental and Dynamic Effects Design Bases,'' and GDC 23, 
``Protection System Failure Modes,'' of Appendix A, ``General Design 
Criteria for Nuclear Power Plants,'' to 10 CFR Part 50. Augmenting 
those general requirements, 10 CFR 50.49, ``Environmental Qualification 
of Electric Equipment Important to Safety for Nuclear Power Plants,'' 
contains the specific

[[Page 32363]]

requirements pertaining to qualification of certain electrical 
equipment important to safety. 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 staff 
considers acceptable for complying with the regulations for 
qualification of safety-related battery chargers and inverters for 
nuclear power plants.
    In July 2007, the NRC published a draft of this guide as DG-1148. 
The public comment period closed on October 2, 2007. The staff's 
responses to the public comments are located in the NRC's Agencywide 
Documents Access and Management System (ADAMS) under Accession No. 
ML080640181.
    Electronic copies of Regulatory Guide 1.210 are available through 
the NRC's public Web site under ``Regulatory Guides'' at http://www.nrc.gov/reading-rm/doc-collections/.
    In addition, regulatory guides are available for inspection at the 
NRC's Public Document Room (PDR), which is located at 11555 Rockville 
Pike, Rockville, MD. The PDR mailing address is USNRC PDR, Washington, 
DC 20555-0001. The PDR can also be reached by telephone at (301) 415-
4737 or (800) 397-4209, by fax at (301) 415-3548, and by e-mail to 
[email protected].
    Regulatory guides are not copyrighted, and NRC approval is not 
required to reproduce them.

    Dated at Rockville, Maryland, this 2nd day of June, 2008.

    For the Nuclear Regulatory Commission.
