有機添加剤を含むMOX粉末を装荷する粉末ホッパーは、有機添加剤の熱劣化を防止するため冷却機能を有するが、将来のプルトニウムの高次化(高発熱化)までは対応できていない。このため、将来の高発熱化に対応した粉末ホッパーを開発するべく、事前試験として粉末ホッパー内のMOX粉末の温度測定を行った。

MOX powder containing organic additives is loaded in a hopper. The hopper has a cooling function to mitigate heat deterioration of organic additives, but its cooling may not be enough for higher order plutonium in the future. So temperature measurement of MOX powder in the hopper was carried out as a preliminarily test for development of cooling hopper.
