NUCLEAR REGULATORY COMMISSION

Draft Regulatory Guide; Issuance, Availability

    The Nuclear Regulatory Commission has issued for public comment a 
draft of a guide planned for its Regulatory Guide Series. This series 
has been developed to describe and make available to the public such 
information as methods acceptable to the NRC staff for implementing 
specific parts of the Commission's regulations, techniques used by the 
staff in evaluating specific problems or postulated accidents, and data 
needed by the staff in its review of applications for permits and 
licenses.
    The draft guide is a proposed Revision 1 to Regulatory Guide 1.152, 
and it is temporarily identified as DG-1039, ``Criteria for Digital 
Computers in Safety Systems of Nuclear Power Plants.'' The guide will 
be in Division 1, ``Power Reactors.'' This regulatory guide is being 
revised to provide current guidance on methods acceptable to the NRC 
staff for promoting high functional reliability and design quality for 
the use of digital computers in safety systems of nuclear power plants. 
The term ``computer'' is used here has a system that includes computer 
hardware, software, firmware, and interfaces. This guide endorses the 
Institute of Electrical and Electronics Engineers Standard Std. 7-
4.3.2-1993, ``Standard Criteria for Digital Computers in Safety Systems 
of Nuclear Power Generating Stations.''
    The draft guide has not received complete staff review and does not 
represent an official NRC staff position.
    Public comments are being solicited on the guide. Comments should 
be accompanied by supporting data. Written comments may be submitted to 
the Rules Review and Directives Branch, Division of Freedom of 
Information and [[Page 29901]] Publications Services, Office of 
Administration, U.S. Nuclear Regulatory Commission, Washington, DC 
20555. Copies of comments received may be examined at the NRC Public 
Document Room, 2120 L Street NW., Washington, DC. Comments will be most 
helpful if received by July 31, 1995.
    Although a time limit is given for comments on this draft guide, 
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.
    Comments may be submitted electronically, in either ASCII text or 
Wordperfect format (version 5.1 or later), by calling the NRC 
Electronic Bulletin Board on FedWorld. The bulletin board may be 
accessed using a personal computer, a modem, and one of the commonly 
available communications software packages, or directly via Internet.
    If using a personal computer and modem, the NRC subsystem on 
FedWorld can be accessed directly by dialing the toll free number: 1-
800-303-9672. Communication software parameters should be set as 
follows: parity to none, data bits to 8, and stop bits to 1 (N,8,1). 
Using ANSI or VT-100 terminal emulation, the NRC NUREGs and RegGuides 
for Comment subsystem can then be accessed by selecting the ``Rules 
Menu'' option from the ``NRC Main Menu.'' For further information about 
options available for NRC at FedWorld, consult the ``Help/Information 
Center'' from the ``NRC Main Menu.'' Users will find the ``FedWorld 
Online User's Guides'' particularly helpful. Many NRC subsystems and 
data bases also have a ``Help/Information Center'' option that is 
tailored to the particular subsystem.
    The NRC subsystem on FedWorld can also be accessed by a direct dial 
phone number for the main FedWorld BBS, 703-321-3339, or by using 
Telnet via Internet, fedworld.gov. If using 703-321-3339 to contact 
FedWorld, the NRC subsystem will be accessed from the main FedWorld 
menu by selecting the ``Regulatory, Government Administration and State 
Systems,'' then selecting ``Regulatory Information Mall.'' At that 
point, a menu will be displayed that has an option ``U.S. Nuclear 
Regulatory Commission'' that will take you to the NRC Online main menu. 
The NRC Online area also can be accessed directly by typing ``/go nrc'' 
at a FedWorld command line. If you access NRC from FedWorld's main 
menu, you may return to FedWorld by selecting the ``Return to 
FedWorld'' option from the NRC Online Main Menu. However, if you access 
NRC at FedWorld by using NRC's toll-free number, you will have full 
access to all NRC systems but you will not have access to the main 
FedWorld system.
    If you contact FedWorld using Telnet, you will see the NRC area and 
menus, including the Rules menu. Although you will be able to download 
documents and leave messages, you will not be able to write comments or 
upload files (comments). If you contact FedWorld using FTP, all files 
can be accessed and downloaded but uploads are not allowed; all you 
will see is a list of files without descriptions (normal Gopher look). 
An index file listing all files within a subdirectory, with 
descriptions, is included. There is a 15-minute time limit for FTP 
access.
    Although FedWorld can be accessed through the World Wide Web, like 
FTP that mode only provides access for downloading files and does not 
display the NRC Rules menu.
    For more information on NRC bulletin boards call Mr. Arthur Davis, 
Systems Integration and Development Branch, U.S. Nuclear Regulatory 
Commission, Washington, DC 20555, telephone (301)415-5780; e-mail 
AXD[email protected]. For more information on this draft regulatory guide, 
contact S.K. Aggarwal at the NRC, telephone (301)415-6005; e-mail 
[email protected].
    Regulatory guides are available for inspection at the Commission's 
Public Document Room, 2120 L Street NW., Washington, DC. Requests for 
single copies of draft or final guides (which may be reproduced) or for 
placement on an automatic distribution list for single copies of future 
draft guides in specific divisions should be made in writing to the 
U.S. Nuclear Regulatory Commission, Washington, DC 20555, Attention: 
Distribution and Mail Services Section; or by fax at (301)415-2260. 
Telephone requests cannot be accommodated. Regulatory guides are not 
copyrighted, and Commission approval is not required to reproduce them.
