Cyber Security for Byproduct Materials Licensees

The U.S. Nuclear Regulatory Commission (NRC) is discontinuing the rulemaking activity that would have developed cyber security requirements for byproduct materials licensees possessing risk- significant quantities of radioactive materials. The purpose of this action is to inform members of the public of the discontinuation of the rulemaking activity and to provide a brief discussion of the NRC's decision. The rulemaking activity will no longer be reported in the NRC's portion of the Unified Agenda of Regulatory and Deregulatory Actions (the Unified Agenda).
