| description | PROBLEM TO BE SOLVED: To use a large filling amount of sodium salt of a solidified body and make it insoluble in water by adding the compound of elements selected from alkali earth metal, transition metal, metalloid or the like to a vitrification base material, and forming to heat and melt them. SOLUTION: In a preprocessing process, radioactive waste liquid containing sodium compound is dried to become powder, and in a storing process, the powder is stored in a storage tank. In a first mixing process, the dried powder is weighed to supply the powder of SiO2 so as to be mixed at a constant rate. In a second mixing process, about 2-22 mol.% of one oxide out of CaO, B2O3, Al2O3, Fe2O3, TiO2 or the like is added to the mixed powder, and sodium oxide in a vitrified and solidified body is made about 26-35 wt.% to be mixed and agitated. In a heating melting process, the heating and melting temperature of a furnace is set at 850-1100 deg.C, and a mixture is put into a crucible to be heated or continuously heated in a cylindrical furnace. In a cooling and solidifying process, it is preferably forcedly cooled at about 500-600 deg.C by furnace outside air cooling, fan air cooling, water cooling or the like. |
