なく繰り返して使用することができるので。Effects of the Invention As described above, according to the present invention, the lid of the shielding container with the lid of the sealed container attached is attached to the shielding container main body that houses the sealed container main body, and the lid is fixed to the shielding container main body. After that, the lid can be fixed to the sealed container main body with a fitting through the through hole of the shielding container lid, and after transportation, only the shielding container lid is removed and the sealed container is taken out from the shielding container, and the radioactive waste is removed together with the sealed container. Since it can be disposed of, the radiation exposure for each worker can be reduced, and the shielding container can be used repeatedly without radioactive contamination.
輸送容器のコストを大幅に低減できる。The cost of transportation containers can be significantly reduced.
