CRUST COMPOSITION, RADIATION DETOXIFYING SYSTEM, METHOD FOR MANUFACTURING CRUST COMPOSITION, AND METHOD FOR DETOXIFYING RADIATION

摘要

PROBLEM TO BE SOLVED: To relatively easily dispose radioactive waste by detoxifying it.SOLUTION: A solid-phase composition is obtained by incinerating: a calcium carbonate composition comprising a geological composition primarily composed of calcium carbonate; a fine geological composition with the grain size of 0.05 mm or less primarily composed of laminar silicate; a siliceous composition primarily composed of a siliceous geological composition; and an iron oxide composition primarily composed of iron oxide-based substance. The solid-phase composition, a reaction rate adjusting material for adjusting a curing rate and/or a hydrogen reaction rate, an appropriate amount of fine aggregate, and an appropriate amount of coarse aggregate are kneaded together with an appropriate amount of water to form a pasty composition. Radioactive material with the concentration of a predetermined value or less is included in the pasty composition.
