NUCLEAR REGULATORY COMMISSION

[NRC-2013-0098]


Embedded Digital Devices in Safety-Related Systems, Systems 
Important to Safety, and Items Relied on for Safety

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft regulatory issue summary; request for comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for 
public comment Draft Regulatory Issue Summary (RIS) 2013-XX, ``Embedded 
Digital Devices in Safety-Related Systems, Systems Important to Safety, 
and Items Relied on For Safety.'' The NRC staff has developed the draft 
RIS to clarify the NRC's technical position on existing regulatory 
requirements for the quality and reliability of basic components with 
embedded digital devices.

DATES: Submit comments by July 19, 2013. Comments received after this 
date will be considered, if it is practical to do so, but the NRC staff 
is able to ensure consideration only for comments received on or before 
this date.

B. Submitting Comments

    Please include Docket ID NRC-2013-0098 in the subject line of your 
comment submission, in order to ensure that the NRC is able to make 
your comment submission available to the public in this docket.
    The NRC cautions you not to include identifying or contact

ADAMS. The NRC does not routinely edit comment submissions to remove 
identifying or contact information.
    If you are requesting or aggregating comments from other persons 
for submission to the NRC, then you should inform those persons not to

publicly disclosed in their comment submission. Your request should 
state that the NRC does not routinely edit comment submissions to 
remove such information before making the comment submissions available 
to the public or entering the comment submissions into ADAMS.

II. Background

    The RIS discusses, and clarifies, the NRC's technical position on 
existing regulatory requirements for the quality and reliability of 
basic components with embedded digital devices. Further, the purpose is 
to also raise awareness that there may be potential safety issues from 
a postulated common cause failure (CCF) if an undetected software error 
should occur in embedded digital devices located in multiple trains of 
redundant safety equipment in nuclear facilities.
    The NRC plans to hold a public meeting to discuss this RIS and the 
issues associated with embedded digital devices. All comments that are 
to receive consideration in the final RIS must still be submitted 
electronically or in writing as indicated below. Additional details 
regarding the meeting will be posted at least 10 days prior to the 
public meeting on NRC's Public Meeting Schedule Web site at http://www.nrc.gov/public-involve/public-meetings/index.cfm.
    The NRC issues RISs to communicate with stakeholders on a broad 
range of matters. This may include communicating staff technical 
positions on matters that have not been communicated to, or, are not 
broadly understood by the nuclear industry.

Proposed Action

    The NRC is requesting public comments on the draft RIS. The NRC 
plans to hold a public meeting in the near future to discuss Draft 
Regulatory Issue Summary (RIS) 2013-XX, ``Embedded Digital Devices in 
Safety-Related Systems, Systems Important to Safety, and Items Relied 
on For Safety,'' and to obtain feedback from members of the public. The 
meeting agenda will be posted at least 10 days prior to the public on 
the NRC's Public Meeting Schedule Web site at http://www.nrc.gov/public-involve/public-meetings/index.cfm. Information regarding topics 
to be discussed, changes to the agenda, whether the meeting has been 
cancelled or rescheduled, and the time allotted for public comments can 
be obtained from the Public Meeting Schedule Web site.

    Dated at Rockville, Maryland, this 8th day of May 2013.

    For the Nuclear Regulatory Commission,
Ian C. Jung,
Chief, Instrumentation, Controls and Electronics Engineering Branch 2 
Division of Engineering, Office of New Reactor.
