[0002] Radioactive waste is generated from nuclear facilities (including nuclear power plants and spent fuel reprocessing plants, etc.). At present, most of the low- and medium-level radioactive waste generated by my country's nuclear facilities is treated with traditional cement solidification. However, cement solidification has the disadvantages of large waste volume increase, poor long-term storage stability, and high leaching rate. Therefore, some domestic nuclear power plants have begun to use high integrity containers (hereinafter referred to as "HIC") to contain radioactive waste, such as Tianwan Nuclear Power Plant. HIC is used to place solidified nuclear waste, which can be safely stored for 300 years under dry and wet, hot and cold, salt corrosion, impact and other environmental conditions; this technology can simplify multiple barriers, do not need to be buried underground, and save a lot of land resources.
[0003] At present, concrete is used as the base material as the sealing material in the concrete HIC capping process, and the problems are:
[0004] a) It is difficult to meet the corrosion resistance requirements for containing more types of waste;
[0005] b) The supporting equipment is complex, the operation process is cumbersome, the equipment investment is large, the manpower demand is large, the cleaning is troublesome, time-consuming and labor-intensive, and secondary pollution such as cleaning waste liquid and dust is generated;
[0006] c) GB36900.2-2018 safety requirements stipulate that the structure and sealing materials of HIC must be compatible with its contents and its environment. If necessary, corrosion-resistant lining, jacket or coating can be installed inside and outside the concrete container. Summary of the invention

[0013] The glue pouring head is fixed at the second end of the glue pouring robot arm. In the glue pouring state, the glue pouring head is located directly above the annular space between the HIC container and the HIC cover plate. The rotating platform can rotate horizontally to carry the HIC and drive the HIC to rotate, and cooperate with the glue pouring head to complete the capping of the HIC.

[0018] Furthermore, in the process device for capping HIC with organic materials as described above, the glue pouring robot arm is equipped with a retractable liquid receiving tray, and the liquid receiving tray can be located below the glue pouring head to prevent glue from dripping elsewhere.
[0019] Furthermore, in the process device for capping HIC with organic materials as described above, a positioning block is provided on the rotating platform, and a guiding slope is arranged on the positioning block to ensure that the positioning accuracy of the HIC is within the range of ±2mm after it is placed.

[0032] First, glue is poured at a high flow rate: the flow rate is controlled within the range of 30-50g / s. When the laser sensor detects that the organic material fills the glue filling hole, the metering pumps of the A and B components are controlled to automatically stop working;
[0033] Then glue is poured at a small flow rate: the rotating platform is started and the metering pumps of components A and B are restarted. The rotating platform rotates at a uniform speed so that the glue pouring head pours at a small flow rate in the annular space between the HIC container and the HIC cover plate. The flow rate is controlled to be less than 20g / s. When the laser sensor detects that it is full again, the metering pumps of components A and B automatically stop working.
[0034] Furthermore, in the process of sealing HIC with organic materials as described above, the components of the organic sealing materials A and B include liquid epoxy resin, modifier and additives.

[0077] The embodiment of the present invention also provides a process for capping HIC using the above device, referring to Figure 7 As shown, the method comprises the following steps:
[0078] Step 1: Place the HIC on the rotating platform and position it accurately. This step can be completed using a factory crane.
[0079] Step 2: Open the HIC cover 19 by means of the liftable cover gripper 13 .
[0080] The specific process is: drive the gripper mechanical arm 12 to rotate, so that the cover gripper 13 is positioned just above the HIC container 21, such as Figure 2 Start the screw lifting mechanism 11 down to a suitable position, start the cylinder of the cover gripper 13, so that the cover gripper 13 holds the HIC cover 19 tightly, such as Figure 3 As shown; the screw lifting mechanism 11 is lifted to a reasonable position, and the gripper mechanical arm 12 is rotated to the initial position, such as Figure 4 shown.
[0081] Step 3: Load the waste steel drum 20 into the HIC container 21. This step can be completed using a factory crane.
[0082] Step 4: Place the HIC cover plate 19 back onto the HIC container 21 by the cover plate gripper 13 .
[0083] The specific process is: drive the gripper robot arm 12 to rotate, so that the cover gripper 13 is repositioned directly above the HIC container 21, start the screw lifting mechanism 11 to descend to a suitable position, and after the cover gripper 13 releases the HIC cover 19, the screw lifting mechanism 11 is lifted to a reasonable position, and the rotating gripper robot arm 12 returns to the initial position.
[0084] Step 5: Adjust the position of the glue injection head 16 to align it with any glue injection hole of the HIC cover plate 19.
[0085] like Figure 5 As shown, the glue pouring robot arm 17 is driven to position the glue pouring head 16 directly above the annular space between the HIC container 21 and the HIC cover plate 19, and the distance between the lower end surface of the glue pouring head 16 and the upper end surface of the HIC cover plate 19 is within 2 to 20 mm. The rotating platform 22 is started to align the glue pouring head 16 with any glue pouring hole of the HIC cover plate 19 (there are three glue pouring holes on the HIC cover plate 19), and the laser sensor 18 is adjusted into place.
[0086] Step 6: Prepare the A and B component organic sealing materials according to the formula.
[0087] Compared with concrete mortar sealing materials, organic sealing materials have better corrosion resistance, which can not only simplify the structure and operation process of the sealing equipment and reduce the generation of secondary radioactive waste, but also improve the compatibility between the packaging container and the waste, and meet the safety requirements of HIC in GB36900.2-2018. Therefore, it can be used to contain more types of radioactive waste, such as evaporation residues and incineration ash generated in fast reactors and reprocessing projects containing large amounts of sodium salts, sulfates, halides, etc. Radioactive waste.
[0088] The organic sealing material described in the present invention includes liquid epoxy resin, curing agent (which may be one or a mixture of polyamide, aromatic amine, polyether amine curing agent, etc.), diluent, flame retardant, toughening agent and other modifiers, and additives such as fly ash, kaolin, silicon dioxide, aluminum hydroxide, etc. may also be added.
[0089] The specific process of preparing organic sealing materials is as follows: prepare organic sealing materials - component A and component B in component A and component B feeding tanks according to the formula, start the stirring paddle and heater, and after stirring evenly, start the A and B component feeding pumps to transport them to their respective feeding tanks, and start their stirring paddles and heaters at the same time.
[0090] Step 7: Open the valve and start the metering pumps of components A and B at the same time, and deliver the organic sealing materials of components A and B to the glue pouring head 16 according to the set flow rate, and cooperate with the rotating platform 22 to complete the glue pouring of HIC.
[0091] The specific method of perfusion is:
[0092] First, glue is poured at a high flow rate. The organic materials of component A and component B are mixed evenly in the glue pouring head 16 and discharged, and flow into the HIC container through any glue pouring hole on the HIC cover plate, and the flow rate is controlled to be about 30-50g / s; at the same time, the laser sensor 18 monitors the liquid level of the organic material. When the laser sensor 18 detects that the organic material fills the glue pouring hole, it feeds back a signal to control the metering pumps of components A and B to stop working;
[0093] Then, glue is poured at a small flow rate. Start the rotating platform 22 and restart the metering pumps of components A and B. The rotating platform rotates at a constant speed, so that the glue pouring head 16 pours at a small flow rate in the annular space between the HIC container 21 and the HIC cover plate 19. The flow rate is controlled to be less than 20g / s. Figure 6 Until the gap between the waste steel drum 20 and the HIC container 21 and the annular space between the HIC container 21 and the HIC cover plate 19 are filled with organic materials, and the laser sensor 18 detects that they are full again, the metering pumps of the A and B components stop working.
[0094] After the filling is completed, the liquid receiving tray 15 is opened to be located under the glue filling head 16, and then the glue filling robot arm 17 is rotated to the initial position to prevent the glue from dripping elsewhere.
[0095] Step 8: After the glue pouring is completed, the HIC is transported to the temporary storage area for curing and solidification.
[0096] Then, repeat steps 1-8 above to fill the next HIC; or reset the device and clean it. When the filling head is blocked, replace it with a new one and dispose of the replaced filling head as waste. Clean the dripping organic material in the liquid receiving tray as needed.
[0097] The present invention provides a process device and method for capping HIC with organic materials. The operation is simple, no pipeline cleaning is required, and the amount of secondary waste generated is greatly reduced. The use of laser sensors to monitor the glue filling state can effectively improve the control of the glue filling system. The equipment is simple, small in size, and more compact in layout. The sealing efficiency is improved, and 5 HIC barrels can be filled with glue every 8 hours. The method fully considers the characteristics of the organic material formula, the feasibility of engineering application, the convenience of operation, and the minimization of the amount of secondary waste generated. The organic material is poured into the annular space between the HIC container and the cover plate or the gap between the waste steel barrel and the HIC container. The combination of inorganic and organic materials further improves the waste containment performance and durability of the concrete container, which can effectively reduce the risk of leakage of radioactive nuclides and other harmful components to the environment during long-term storage, and improve the disposal safety of radioactive waste.
[0098] The above embodiments are merely illustrative of the present invention, and the present invention may also be implemented in other specific ways or other specific forms without departing from the gist or essential features of the present invention. Therefore, the described embodiments should be considered illustrative rather than restrictive in any respect. The scope of the present invention should be described by the appended claims, and any changes equivalent to the intent and scope of the claims should also be included within the scope of the present invention.

7. The process for capping HIC according to claim 6, characterized in that: In step S5, the distance between the lower end surface of the glue filling head and the upper end surface of the HIC cover plate is within a range of 2 to 20 mm.
8. The HIC capping process according to claim 7, characterized in that: The specific process of glue filling in step S7 is as follows: First, glue is poured at a high flow rate: the flow rate is controlled within the range of 30-50g / s. When the laser sensor detects that the organic material fills the glue filling hole, the metering pumps of components A and B are controlled to automatically stop working; Then, glue is poured at a small flow rate: the rotating platform is started and the metering pumps of components A and B are restarted. The rotating platform rotates at a constant speed, so that the glue pouring head pours glue at a small flow rate in the annular space between the HIC container and the HIC cover plate. The flow rate is controlled to be less than 20g / s. When the laser sensor detects that the glue is full again, the metering pumps of components A and B automatically stop working.
