DOE orders for Termination of Safeguards and graded material attractiveness was evaluated. As a result, based on the disposition experience through down blending, graded material attractiveness and its policy would be referred for Japan's case for the termination of safeguards.

To clarify nuclear non-proliferation and nuclear security measures for nuclear fuel cycle backend options including direct disposal of spent fuel, analysis of the nuclear material attractiveness categorization in the United States, difficulty in recovering plutonium from spent fuel and plutonium concentration and isotopic ratio in spent fuel were investigated.

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.
