The solidification and transportation device has the advantages of being high in safety, easy to operate, convenient to move, simple in structure, high in expandability and the like, the defects that an existing radioactive substance transportation method and device are complex in structure, poor in expandability and the like can be effectively overcome, and the solidification and transportation device can be suitable for transportation of radioactive substances of different structural forms and overall transportation of a reactor.

Description

technical field [0001] The present invention relates to the related technical field of radioactive material transportation, in particular to a coagulation transport device and method based on coagulable fluid containing radioactive material. Background technique [0002] At present, the method of transporting radioactive substances and the devices for this method mainly use solid storage structural devices to fix and shield radioactive substances, such as spent fuel transport tanks for spent fuel transportation, mainly through component shelves, neutron absorbers, shielding Materials, cushioning materials, heat-conducting materials, and fire-proof and heat-insulating containers mainly adopt the solid structure design concept of layer-by-layer containment, which is not only bulky, but also complex in design and expensive, especially the buffer system designed to deal with falling accidents , but also increased the volume and weight of the tank. [0003] In the future, there ...
