放射性廃棄物処分にかかわる負担軽減のために、大量の長半減期核分裂生成物(LLFP)を核変換する方法を提案し、核変換効率,炉心積載量,照射用ターゲットに関する検討をもとに、高温ガス炉の核変換特性について報告する。

In order to decrease of nuclear waste, the nuclear transmutation method with HTGRs (High Temperature Gas-cooled Reactor) by which a large amount of LLFP (Long Lived Fission Product) can be transmuted is proposed. This paper describes the characteristics of the nuclear transmutation, which are the relations between transmutation efficiency and the amount of loaded LLFP into the core or the characteristics of the irradiation target, are reported.
