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).
