ABSTRACT:
An apparatus for discharging radioactive waste from its container comprises a truck movable toward and away from the container by a driving motor, a seizing member including claws capable of closing and opening to seize and release the radioactive waste little by little, a cylinder connected to the seizing member for closing and opening the claws, a further cylinder for tilting the seizing member downwardly to eject the seized waste and a detector for detecting pressure caused by the seizing member penetrating into the waste when the truck is driven toward the container by the driving motor to produce signals for stopping the truck and operating the first mentioned cylinder to close the claws. The apparatus safely and securely discharges little by little the radioactive waste filled in the storage container without any risk of exposing operators to the radioactive radiation emitted from the waste, thereby saving time and labor and making easy next processes for burning it.
