[2L02] Basic Study on actinide leaching and waste management of MCCI debris

(2)Relation between the temperature of fuel debris generation and leaching behavior of actinides to contaminated water

*Akito Nagatomo1, Akira Kirishima1, Daisuke Akiyama1, Nobuaki Sato1, Takayuki Sasaki2 (1. IMRAM, Tohoku Univ., 2. Kyoto University garaduate school of engineering and faculty of engineering)

Keywords:MCCI fuel debris, Minor actinide, Leaching behavior, Fission products, contaminated water

1200℃または1600℃で熱処理を行い、ウラン酸化物、ジルコニア、セメント構成成分およびFP(137Cs,85Sr,152Eu)とMA(237Np,241Am)トレーサーを含む模擬デブリを調整した。これを海水及び純水に浸漬し、アクチノイド溶出機構を中心に調べ、デブリ生成時の温度とアクチノイド溶出挙動の関係を考察した。
