[2B06] Development of stable solidification technique of ALPS sediment wastes by apatite ceramics

(4)Development of low temperature solidification technologies for apatite powder

*Takatoshi Hijikata1, Masahiko Nakase2, Kazuo Utsumi2, Kenji Takeshita2 (1. Central Reasearch Institute of Electric Power Industry, 2. Tokyo Institute of Technology)

Keywords:Fukushima Daiichi Nuclear Power Station, ALPS sediment , Solidification, Apatite, 1-axis hot press

市販のアパタイト粉末を用いて、100~600℃とプレス圧力64~325MPaをパラメーターとして、一軸ホットプレスを用いて固化条件について把握した。理論密度の約90%の固化体が得られた。
