A new rule proposed by the Nuclear Regulatory Commission (NRC) would expand the categories of information considered by the agency to be sensitive. Such data would be added to a special category of sensitive unclassified information, termed safeguards information (SGI), that would be protected from unauthorized disclosure.Current SGI includes data on power reactors, research and test reactors, and spent-fuel storage installations. Under the new rule, information such as engineering or safety analyses, emergency planning procedures, or scenario training materials relating to facility protection would be considered SGI. Also protected would be information concerning the tactics and capabilities required to defend against attempted radiological sabotage or theft of nuclear material. @ To read the full text, visit Security Management Online.
