いる。(Prior art) Combustible waste contaminated with radioactivity generated from radioactive material handling facilities such as nuclear power plants is generally incinerated, and the incinerated ash is stored in drum cans, etc. It is normally filled with water and stored at an appropriate location within the facility. However, these incinerated ash are in the form of powder and granules, so when transporting or storing drums filled with incinerated ash, it is desirable to stabilize the incinerated ash and to reduce its volume. A lot of research has been done on it.

つてしまう欠点があつた。(Problems to be Solved by the Invention) However, in the first method, the cement solidification method, it is difficult to mix waste or incinerated ash with cement to obtain a solidified product with stable density and strength. It is necessary to set the weight ratio of cement to 1 part of ash, etc. to 4 or more of cement, which has the disadvantage that the volume of the solidified material becomes larger than the volume of ash, etc., resulting in an increase in volume.

A high temperature is achieved by heating a metal container with 1000-1200
It can only be used at a temperature of 30°F (°C), and it cannot be used to melt wastes that melt at higher temperatures.It also has the drawback that it is a batch-type process, which requires a lot of effort to melt, and the amount processed at one time is small. Ta.
