regulatory requirements for the quality and reliability of safety-
related equipment with embedded digital devices.

DATES: Submit comments by July 7, 2014. 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.

remove such information before making the comment submissions available 
to the public or entering the comment submissions into ADAMS.

II. Discussion

    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.
    The NRC staff has developed draft revised RIS 2014-XX, ``Embedded 
Digital Devices in Safety-Related Systems,'' to clarify the NRC's 
technical position on existing regulatory requirements for the quality 
and reliability of safety-related equipment 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.
    This RIS is available electronically through the Agencywide 
Documents Access and Management System (ADAMS) Accession Number 
ML13338A769. This RIS is a revision of the original draft RIS 2013-XX, 
``Embedded Digital Devices in Safety-Related Systems, Systems Important 
to Safety, and Items Relied on For Safety,'' (ADAMS Accession Number 
ML12248A065) issued for public comment May 20, 2013 and reflects 
adjustments made in response to the public comments received. A table 
of the public comments received on the original draft RIS with the NRC 
staff response is publically available electronically (ADAMS Accession 
Number ML13351A204).

    Dated at Rockville, Maryland, this 22nd day of April 2014.

    For the Nuclear Regulatory Commission.
