It serves to reduce the radioactive concentration.

If the radioactive concentration is reduced, it can be treated like a general waste, and thus treatment efficiency can be increased. Therefore, a large space is not necessarily required as before, and the processing cost is not high.

For reference, the radioactive waste applied to the ultrasonic cleaning device according to the present embodiment may include contaminated waste such as a wide range of solidified wastes such as sand, gravel, activated carbon, anthracite, and concrete.

The hopper 160 is a structure that is detachably coupled to the lower region of the drum 120 for reducing nuclides in the device body 110. This hopper 160 serves to store radioactive waste and demineralized water in the drum 120 for reducing nuclides.

In this embodiment, the inclined surface 161 is formed on the bottom of the hopper 160 so that the height gradually decreases toward one end. Therefore, radioactive waste and demineralized water falling into the hopper 160, particularly demineralized water, can flow down without being collected.

At this time, a removable screen 162 having a mesh structure is coupled to the lowest position of the hopper 160. Accordingly, the demineralized water can escape through the detachable screen 162 to separate the radioactive waste from the demineralized water. In particular, it is possible to separate the demineralized water and obtain only solid radioactive waste.

It may include a handle 173, a plurality of wheels 174 coupled to the lower end of the bogie body 171, and a valve 175 connected to one side of the bogie body 171.

Since the filter unit 172 is applied to the waste transfer cart 170, the radioactive waste and demineralized water may be separated and stored in the waste transfer cart 170.

Demineralized water may be disposed of separately by opening the valve 175, and solid radioactive waste may be transferred to another place. At this time, the transferred radioactive waste is already in a state in which the radioactivity concentration has been significantly reduced, so that it can be treated together with general waste.

Meanwhile, the input unit 180 and the controller 190 are further mounted in the ultrasonic cleaning apparatus 100 for reducing radioactive waste nuclides according to the present embodiment.
