The Nuclear Regulatory Commission (NRC) has issued Revision 1 to Regulatory Issue Summary (RIS) 2005-31: “Control of Security-Related Sensitive Unclassified Nonsafeguards Information Handled By Individuals, Firms, and Entities Subject to NRC Regulation of the Use of Source, Byproduct, and Special Nuclear Material” (ML16196A237) on December 26, 2017. The NRC has developed criteria enclosed in this RIS for identifying security-related sensitive information that the staff encourages licensees to screen out or to mark and protect as sensitive information, particularly before those licensees that handle source, byproduct, or special nuclear material submit documents to the NRC. The advice in this RIS and its enclosures does not apply to classified information, Safeguards Information, or Safeguards Information-Modified Handling, which by law must be withheld from the public.
