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 (DG), entitled, ``Bypassed and 
Inoperable Status Indication for Nuclear Power Plant Safety Systems,'' 
is temporarily identified by its task number, DG-1205, which should be 
mentioned in all related correspondence. DG-1205 is proposed Revision 1 
of Regulatory Guide 1.47.
    DG-1205 describes a method that the staff of the NRC considers 
acceptable for use in complying with the NRC's regulations with respect 
to bypassed and inoperable status indication for nuclear power plant 
safety systems. The regulatory framework that the NRC has established 
for nuclear power plants consists of a number of regulations and 
supporting guidelines applicable to bypassed and inoperable status 
indication, including, but not limited to, General Design Criterion 
(GDC) 1, ``Quality Standards and Records,'' GDC 13, ``Instrumentation 
and Control,'' GDC 19, ``Control Room,'' GDC 21, ``Protection System 
Reliability and Testability,'' GDC 22, ``Protection System 
Independence,'' and GDC 24, ``Separation of Protection and Control 
Systems,'' as set forth in Appendix A, ``General Design Criteria for 
Nuclear Power Plants,'' to Title 10, Part 50, ``Domestic Licensing of 
Production and Utilization Facilities,'' of the Code of Federal 
Regulations (10 CFR part 50). GDC 1 requires that structures, systems, 
and components important to safety be designed and installed to quality 
standards commensurate with the importance-to-safety of the functions 
to be performed. GDC 13 requires that appropriate controls be provided 
to maintain variables and systems that can affect the fission process, 
the integrity of the reactor core, the reactor coolant pressure 
boundary, and the containment and its associated systems within 
prescribed operating ranges. GDC 19 requires that a control room be 
provided from which actions can be taken to operate the nuclear power 
unit safely under normal operating conditions. GDC 21 requires that the 
protection system be designed for high functional reliability and 
inservice testability. GDC 22 requires that the protection system be 
designed to ensure that the effects of normal operating, maintenance, 
and testing on redundant channels do not result in the loss of the 
protection function. GDC 24 requires that interconnection of the 
protection and control systems be limited to ensure that safety is not 
significantly impaired.

II. Further Information

    The NRC staff is soliciting comments on DG-1205. Comments may be 
accompanied by relevant information or supporting data and should 
mention DG-1205 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).
    Personal information will not be removed from your comments. You 
may submit comments by any of the following methods:
    1. Mail comments to: Rulemaking, Directives, and Editing Branch, 
Office of Administration, U.S. Nuclear Regulatory Commission, 
Washington, DC 20555-0001.
    2. E-mail comments to: [email protected].
    3. Hand-deliver comments to: Rulemaking, Directives, and Editing 
Branch, Office of Administration, U.S. Nuclear Regulatory Commission, 
11555 Rockville Pike, Rockville, Maryland 20852, between 7:30 a.m. and 
4:15 p.m. on Federal workdays.
    4. Fax comments to: Rulemaking, Directives, and Editing Branch, 
Office of Administration, U.S. Nuclear Regulatory Commission at (301) 
415-5144.
    Requests for technical information about DG-1205 may be directed to 
the NRC contact, Khoi Nguyen at (301) 415-0701 or e-mail to 
[email protected].
    Comments would be most helpful if received by December 22, 2008. 
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.
