Categories of special nuclear material
Term · Nuclear energy and radiation · MLC-T-NUC-000057
The NRC groups special nuclear materials and the facilities that possess them into three categories based upon the materials’ potential for use in nuclear weapons or their “strategic significance”:
• Category I: High strategic significance
• Category II: Moderate strategic significance
• Category III: Low strategic significance
The NRC’s physical security and safeguards requirements differ by category, with Category I facilities subject to more stringent requirements because they pose greater security and safeguards risks.
