Radioactive waste solidifying apparatus, solidification treatment method of radioactive waste solidified body, and manufacturing method of radioactive waste solidified body

摘要

PROBLEM TO BE SOLVED: To provide a radioactive waste solidification apparatus etc. capable of efficiently solidifying radioactive waste.SOLUTION: The radioactive waste solidification apparatus includes: a mixing section; a forming section: and a firing section. The mixing section adds clay mineral to incineration ash containing radioactive substance and mixes the same. The forming section shapes the mixture containing the incineration ash and the clay mineral mixed by the mixing section into a compact. The firing section fires the compact shaped by the forming section to solidify the same.
