Solidification processing apparatus for radioactive waste materials.

摘要

A solidification processing apparatus for radioactive waste materials comprises a tank (2) for a solidifying agent, a waste material vessel (4) connected to the tank (2), pouring control unit (6,7,19) for controlling pouring of the solidifying agent into the vessel, and a heating and curing chamber (12) for heating the vessel (14) by indirect heating unit after pouring the solidifying agent onto the waste materials in the vessel to polymerize and set the solidifying agent, thereby solidifying the radioactive waste materials. With this arrangement, the solidifying agent capable of good impregnation is poured into the vessel (4) filled with radioactive waste materials, and the amount poured is controlled by the pouring control unit (6,7,19). Use of indirect heating avoids risk of combustion if the solidifying agent is combustible. The solidifying agent can be polymerized and set in a relatively short time, and the radioactive waste materials can be stably solidified.
