High-integrity container with anti-floating mechanisms for radioactive waste disposal

Abstract

The invention provides a high-integrity container with anti-floating mechanisms for radioactive waste disposal. The high-integrity container mainly comprises a container with an opening in the top, aplurality of anti-floating mechanisms and a plurality of workpieces, wherein the anti-floating mechanisms are arranged at the upper part of the inner wall of the container, the workpieces are arrangedin the container, and when the workpieces float, at least one contact surface or contact point exists between the top of the uppermost workpiece and the anti-floating mechanisms. The anti-floating mechanisms allow the workpieces to be smoothly put into the container, and to avoid floatation during secondary grouting, so that the workpieces can be completely sealed; the anti-floating mechanisms can freely stretch out, draw back and rotate, and one-way movement of the workpieces can be achieved without the help of external force.

Description

technical field [0001] The invention belongs to the field of waste treatment equipment, and relates to a high-integrity container for low- and medium-level radioactive waste disposal, in particular to a high-integrity container for radioactive waste disposal with an anti-floating mechanism. Background technique [0002] During the operation of nuclear power plants, a large amount of waste containing radioactive substances will be generated, and these wastes containing radioactive substances must be treated before they can be discharged. [0003] When dealing with waste containing radioactive substances, place the waste of radioactive substances in the workpiece, then place the waste of radioactive substances in the radioactive waste disposal container and add a top cover. After the secondary grouting, the workpiece is completely covered so that the workpiece is completely sealed. However, the workpiece will generate buoyancy under the action of concrete during the second gro...

AI Technical Summary

Problems solved by technology

However, the workpiece will generate buoyancy under the action of concrete during the second grouting. Under the joint action of the buoyancy and the weight of the workpiece, the workpiece will float up during the second grouting. In severe cases, the top cover of the container will float up, resulting in secondary The primary grouting effect is poor or the workpiece cannot be sealed at all, which eventually leads to complete sealing failure of the workpiece
