。Currently, radioactive waste generated at nuclear power plants is processed in radioactive waste processing equipment, and in the final stage of processing, the volume is reduced and the remaining waste is solidified with concrete or asphalt, filled into drums, and placed on the site of the power plant. A warehouse and other facilities have been set up within the building, which are being stored and managed and are not used at all. Furthermore, there are limits to storage within the narrow premises. Therefore, in order to solve this problem, the filled containers that had been stored will be used as construction materials.

うに凹凸を設ける。FIG. 1 shows a concrete IJ structure for filling radioactive waste that can be used as a construction material. In FIG. A metal mortar 2 is provided for filling radioactive waste.
and a lid 3. Radioactive waste 1 is filled into a metal mortar 2, capped with a lid 3, and sealed with a welded part 8 to prevent moisture from entering. After that, it is filled with filling concrete 7 and sealed. The concrete structure is made of reinforcing steel 5
It has sufficient strength as a construction material, and the supplementary loose shields 4 and 6 and concrete 6 and 7 keep the surface dose rate below 0.2 mR/hr, which is necessary for shielding. In addition, unevenness will be provided on the upper and lower parts of the conventional structure to enable stacking.
