[0002] When a reactor is in operation, there are irradiated liquids, such as coolants, chemical reagents, or solutions specifically used to produce specific isotopes. Among them, the liquid isotopes irradiated in the reactor usually undergo a series of changes, such as radioactive decay and the formation of new isotopes. They have high radioactivity, and radioactive isotopes with short half-lives may decay rapidly, but long-lived isotopes may also be produced. These liquid isotopes may undergo chemical changes during irradiation, such as oxidation or reduction reactions. Their handling and storage require special care to prevent the leakage of radioactive materials and environmental contamination.

[0003] That is to say, the liquid isotopes irradiated in the reactor are highly radioactive, corrosive and toxic. In the process of radioactive liquid treatment, the irradiated liquid isotopes need to be transported and stored. How to effectively shield the radiation and facilitate access, storage and transportation is a difficult problem that needs to be solved, that is, it is difficult to safely transport the irradiated liquid isotopes in the reactor. Summary of the invention

[0004] In view of the technical problem that liquid isotopes after irradiation in a reactor are difficult to transport safely, the present invention provides a radioactive, highly corrosive and toxic liquid transport device and transport method, which is provided with a storage container, a flexible protective structure, a rigid shell and a radiation shielding structure, and can effectively shield radiation and protect the storage container to ensure transportation safety.

[0007] It should be noted that the liquid isotopes irradiated in the reactor are highly radioactive, corrosive and toxic. In the process of handling radioactive liquids, the irradiated liquid isotopes need to be transported and stored. How to effectively shield the radiation and facilitate access, storage and transportation is a difficult problem that needs to be solved, that is, it is difficult to safely transport the irradiated liquid isotopes in the reactor.

[0044] In order to solve the above-mentioned problems, the inventor innovatively designed the following technical solution, and the specific implementation solution of this application will be described in detail with reference to the accompanying drawings.

[0045] Example 1

[0046] Combination Figure 1 The present embodiment provides a radioactive highly corrosive toxic liquid transport device, comprising: a storage container 10, wherein the storage container 10 is capable of storing radioactive highly corrosive toxic liquid in a sealed manner; a flexible protective structure 20, wherein the flexible protective structure 20 is covered on the outside of the storage container 10; a rigid shell 30, wherein the lower end of the rigid shell 30 is closed and the upper end of the rigid shell 30 is open; a radiation shielding structure 40, wherein the radiation shielding structure 40 is adapted to the inner cavity of the rigid shell 30, and a concave cavity for placing the storage container 10 is provided in the middle of the radiation shielding structure 40; a sealing cover body 50, wherein the sealing cover body 50 is detachably connected to the upper end of the rigid shell 30, wherein the sealing cover body 50 is capable of sealing the rigid shell 30, and when the cover is closed, the sealing cover body 50 abuts against the flexible protective structure 20.

[0047] Specifically, the storage container 10 includes: a storage bottle body 11, which is made of glass and has a bottle mouth at the upper end of the storage bottle body 11; and a flexible bottle plug 12, which is adapted to the bottle mouth. The glass storage bottle body 11 can withstand the corrosion of radioactive highly corrosive toxic liquids, and the liquid level in the storage bottle body 11 can also be directly observed to prevent the radioactive highly corrosive toxic liquid loaded into the storage container 10 from exceeding the capacity of the storage bottle body 11. At the same time, the use of the flexible bottle plug 12 to close the bottle mouth can not only ensure the sealing of the storage bottle body 11, but also facilitate the placement and removal of the flexible bottle plug 12, which is conducive to remote operation.

[0048] Generally speaking, the outer side wall of the bottle mouth is provided with a gripping groove 13, and the gripping groove 13 is used to accommodate bottle-taking gripping fingers, so as to facilitate gripping the storage container 10 by a remote tool, thereby realizing remote operation of placing and removing the storage container 10.

[0049] The flexible protective structure 20 is mainly used for shock absorption to prevent the glass container from being damaged by collision, and is usually made of flexible materials such as rubber, foam, sponge, etc. In order to facilitate the loading and unloading of the radioactive and highly corrosive toxic liquid into and out of the storage container 10, the flexible protective structure 20 is usually made into a split structure with upper and lower sections, so that when loading and unloading the radioactive and highly corrosive toxic liquid into and out of the storage container 10, it is convenient to remove the flexible protective structure 20 from the upper end of the storage container 10, which is conducive to remote operation.

[0050] It is understandable that the rigid shell 30 is usually made of metal, and for nuclear facility related products, it is usually made of stainless steel. The rigid shell 30 is usually cylindrical, and its main part is a cylinder structure, and a support bottom plate 31 is arranged at the bottom to ensure the stability of the rigid shell 30. The support bottom plate 31 is usually welded to the lower end of the cylinder structure.

[0051] The radiation shielding structure 40 needs to shield radiation, and is made of lead, and its thickness can be calculated according to radiation protection requirements.

[0052] Combination Figure 1 and Figure 2 In this embodiment, the sealing cover 50 is connected to the rigid shell 30 by a plurality of connecting bolts 60, so as to facilitate fixing the sealing cover 50 on the rigid shell 30 and removing the sealing cover 50 from the rigid shell 30, while ensuring the stability of the sealing cylinder cover. The number of connecting bolts 60 is generally three or more, and four are provided in this embodiment.

[0053] It can be understood that the connecting bolt 60 includes: a connecting screw 61, one end of which is hinged to the rigid shell 30, and the other end of the connecting screw 61 can pass through the sealing cover body 50; a connecting nut 62, which is adapted to the connecting screw 61, and through which the sealing cover body 50 can be pressed onto the upper end of the rigid shell 30.

[0054] Combination Figure 2 and Figure 3 Specifically, a plurality of connecting ear plates 32 are fixed to the upper side wall of the rigid shell 30, and the plurality of connecting ear plates 32 are evenly distributed along the axial direction of the rigid shell 30, and the connecting screw 61 is hinged to the connecting ear plate 32; the sealing cover body 50 is provided with a plurality of connecting grooves 51, and the plurality of connecting grooves 51 are evenly distributed along the circumference of the sealing cover body 50, and the connecting grooves 51 extend from the side wall of the sealing cover body 50 to its center; wherein the connecting screw 61 can move relative to the corresponding connecting groove 51, and when the sealing cover body 50 is covered on the rigid shell 30, the bottom of the connecting groove 51 is located on the outside of the rigid shell 30, so that the fixing and disassembly of the sealing cover body 50 can be achieved by flipping the connecting screw 61, which is conducive to remote operation of covering and removing the sealing cover body 50.

[0055] It should be understood that at least four connecting ear plates 32 are correspondingly arranged on the rigid shell 30, and in order to ensure the stability of the connection between the close connection screw 61 and the rigid shell 30, in this embodiment, four pairs of ear plates are evenly distributed on the circumference of the upper end of the rigid shell 30, and each ear plate is welded to the rigid shell 30, and the lower end of the connecting screw 61 is hinged to the corresponding two ear plates. Correspondingly, at least one connecting groove 51 is arranged on the sealing cover 50, so that the connecting groove 51 and the connecting screw 61 can correspond one to one.

[0056] Thus, the connecting screw 61 can rotate relative to the connecting groove 51 along the hinge axis hinged with the rigid shell 30. When the connecting screw 61 rotates to the vertical direction, the sealing cover 50 and the sealing rigid shell 30 can be tightened by tightening the connecting nut 62. In addition, the cooperation between the connecting screw 61 and the connecting groove 51 can play a guiding role, so that the sealing cover 50 can be quickly installed on the upper end of the rigid shell 30.

[0057] In this embodiment, the connecting nut 62 is a butterfly nut, and the connecting nut 62 is loosened and tightened by remote operation.

[0058] On this basis, the lower section of the sealing cover body 50 is provided with a pressure ring 52, and the pressure ring 52 is adapted to the upper end of the concave cavity of the radiation shielding structure 40; the outer sleeve of the pressure ring 52 is provided with a sealing ring 53, and the sealing ring 53 can seal the gap between the sealing cover body 50 and the radiation shielding structure 40, so as to facilitate the sealing of the rigid shell 30 through the sealing cover body 50, and also facilitate the tight pressing of the flexible protective structure 20.

[0059] It can be known that a connecting lug 54 is provided in the middle of the sealing cover body 50, and the connecting lug 54 is used to connect to a lifting device so as to facilitate remote transportation of the entire device through the lifting device.

[0060] In summary, the radioactive highly corrosive toxic liquid transport device provided in this embodiment includes a storage container 10, a flexible protective structure 20, a rigid shell 30, a radiation shielding structure 40, and a sealing cover 50. The storage container 10 can store radioactive highly corrosive toxic liquid in a sealed manner to prevent the evaporation gas from escaping after the radioactive highly corrosive toxic liquid is stored in the storage container 10, and can also prevent the radioactive highly corrosive toxic liquid from spilling due to the deflection of the storage container 10 during the movement of the storage container 10. The flexible protective structure 20 is coated on the outside of the storage container 10 to perform collision protection on the storage container 10 through the flexible protective structure 20 to prevent the storage container 10 from being damaged due to bumps during transportation.

[0061] At the same time, the lower end of the rigid shell 30 is closed and the upper end of the rigid shell 30 is open, the radiation shielding structure 40 is adapted to the inner cavity of the rigid shell 30, and a concave cavity for placing the storage container 10 is provided in the middle of the radiation shielding structure 40, so as to shield the radiation of the radioactive highly corrosive toxic liquid through the radiation shielding structure 40 to avoid excessive radiation intensity of the radioactive highly corrosive toxic liquid leaking out, and at the same time, the rigid structure is wrapped around the radiation shielding structure 40 to protect the radiation shielding structure 40 to avoid damage to the radiation shielding structure 40 due to bumps during transportation, the sealing cover 50 is detachably connected to the upper end of the rigid shell 30, the sealing cover 50 can seal the rigid shell 30, and in the closed state, the sealing cover 50 abuts against the flexible protective structure 20, so as to seal the rigid shell 30 through the sealing cover 50 while pressing the storage container 10 therein, so as to avoid relative shaking between the storage container 10 and the radiation shielding structure 40 during transportation, thereby causing damage to the storage container 10.

[0062] Therefore, when transporting radioactive highly corrosive and toxic liquids, the radioactive highly corrosive and toxic liquids are loaded into the storage container 10 so as to be sealed and stored in the storage container 10. Then, the flexible protective structure 20 is covered on the outside of the storage container 10, and the flexible protective structure 20 is placed in the concave cavity of the radiation shielding structure 40 so as to provide collision protection for the storage container 10 through the flexible protective structure 20 and shield the radiation of the radioactive highly corrosive and toxic liquid through the radiation shielding structure 40. Then, the sealing cover 50 is covered on the rigid shell 30 to seal the rigid shell 30 to complete the packaging and avoid shaking of the storage container 10 during transportation. Finally, the rigid shell 30 is transported to the radioactive highly corrosive and toxic liquid treatment area to complete the transportation of the radioactive highly corrosive and toxic liquid and facilitate subsequent treatment.

[0063] In summary, the radioactive highly corrosive toxic liquid transfer device provided in this embodiment can effectively shield radiation and protect the storage container 10 to ensure the safety of transportation and reduce the risk of personnel exposure. It also solves the problem of remote operation and has the functions of remote access, remote lifting, and remote sealing of solutions. It can be used for radiation shielding, transportation, and storage of liquid isotopes after reactor irradiation.

[0081] S53, using a long-handled tool to remotely pick up the upper portion of the flexible protective structure 20;

[0082] S54, using a long-handled clamp to clamp the clamping groove 13 at the upper end of the storage bottle body 11, and clamping the designated glove box to allow the operator to perform subsequent operations.

[0083] In summary, the method for transporting radioactive highly corrosive toxic liquids provided in this embodiment is based on the radioactive highly corrosive toxic liquid transport device recorded in Example 1. The radioactive toxic corrosive liquid is first loaded into the storage container 10 to store the radioactive highly corrosive toxic liquid in a closed manner through the storage container 10. Then, the flexible protective structure 20 is covered on the outside of the storage container 10, and the flexible protective structure 20 is placed in the concave cavity of the radiation shielding structure 40. The storage container 10 is protected from collision by the flexible protective structure 20, and the radiation shielding structure 40 is used to shield the radiation of the radioactive highly corrosive toxic liquid. Then, the sealing cover 50 is covered on the rigid shell 30 to seal the rigid shell 30 to complete the packaging and prevent the storage container 10 from shaking during the transportation process. Then, the rigid shell 30 is transported to the radioactive highly corrosive toxic liquid treatment area, and the sealing cover 50 is opened, and the storage container 10 is moved to the corresponding glove box to complete the transportation of the radioactive highly corrosive toxic liquid.

[0084] Therefore, during the transportation of highly radioactive and corrosive toxic liquids, the storage container 10 is protected from collision by the flexible protective structure 20, and the radiation of the highly radioactive and corrosive toxic liquid is shielded by the radiation shielding structure 40. This can effectively shield the radiation and protect the storage container 10, thereby ensuring the safety of transportation and reducing the risk of exposure to personnel.

[0085] It solves the problem of remote operation and has the functions of remote taking and placing of solutions, remote lifting and remote sealing, reducing the risk of personnel exposure.
