This study discusses the safeguards and nuclear security requirements for disposition of radioactive waste including nuclear materials. This research examines how the US Department of Energy (DOE) evaluates and regulates the disposal of waste. In this research, it is ascertained that the categorization of the material attractiveness is determined by the relative effort required to convert that material into a device, and self-protection characteristics (radioactivity). This paper reports the result of the DOE's implementation of safeguards and security measures.
