SOLIDIFICATION MATERIAL AND SOLIDIFICATION METHOD OF RADIOACTIVE INCINERATION ASH
PROBLEM TO BE SOLVED: To provide a high-intensity solidified body that has a high fill factor into a disposal container, suppresses a crack due to expansion during forming a solidified body, and can stably hold a radioactive material, even when a radioactive incineration ash contains a radioactive material and salts of a high salinity concentration, and to provide a method of solidifying the solidified body in a rapid processing, with a small number of processes, and at a high workability.SOLUTION: A solidified body contains hexa metaphosphate and cement used for solidifying a radioactive incineration ash.SELECTED DRAWING: None
【課題】放射性物質と、高塩分濃度の塩類を含む放射性焼却灰であっても、処分容器への充填率が高く、固化体形成時の膨張によるひび割れを抑止して、放射性物質を安定に保持できる高強度の固化体及び、前記固化体を、迅速な処理で少ない工程数で、作業性良く、行なえる固化方法を提供する。【解決手段】放射性焼却灰の固定に用いる、ヘキサメタリン酸塩およびセメントを含むことを特徴とする固化材、を提供する。【選択図】なし
