## Abstract

The Nuclear Regulatory Commission (NRC) is amending its regulations to implement a National Source Tracking System for certain sealed sources. The amendments require licensees to report certain transactions involving these sealed sources to the National Source Tracking System. These transactions include manufacture, transfer, receipt, disassembly, or disposal of nationally tracked sources. The amendments also require each licensee to provide its initial inventory of nationally tracked sources to the National Source Tracking System and annually reconcile the information in the system with the licensee's actual inventory. In addition, the amendments require manufacturers to assign a unique serial number to each nationally tracked source.
