[0038] Nuclear power plants will replace a large amount of radioactive waste, such as CRDM (control rod drive mechanism) shell, CRDM tube seat, spent fuel rack, and radioactive waste such as waste resin, waste filter, protective clothing, and solidified radioactive waste liquid generated during the operation of the nuclear power plant, due to equipment failure, preventive maintenance, equipment upgrade, process system modification and other reasons during long-term operation. These wastes are usually stored in the hot engine repair shop. The continuous accumulation of radioactive waste occupies a large space in the plant, directly affecting the normal maintenance activities in the hot engine repair shop of the nuclear power plant, and the radioactive non-metal causes radiation damage to the operators in the plant. In the related art, in order to cooperate with the working of the processing device, a hoisting device is also provided, which is located above the processing device and is used to move the radioactive waste, so that the overall height of the workstation is too high, and the workstation cannot be quickly removed from the plant after the work is completed, thereby occupying the space in the plant.

[0039] Based on the above problems, the present application provides a radioactive waste treatment workstation, which can reduce the space occupation in the plant. The radioactive waste treatment workstation (hereinafter referred to as the workstation) refers to FIG. 1, which is a structural schematic diagram of the first radioactive waste treatment workstation of the present application, which comprises a processing device 100 and a hoisting device 200.

[0040] The processing device 100 comprises a first bearing 110 and a processing module. The first bearing 110 is, for example, a support or a box body. The processing module is connected to the first bearing 110. The processing module is used to process radioactive waste (hereinafter referred to as waste). The processing mode of the processing module on the waste includes, but is not limited to, cutting, sorting, disassembling or decontamination. For example, the processing module comprises a cutting mechanism 120, which is used to cut the radioactive waste, so as to cut the waste into waste pieces of corresponding size and shape, so as to facilitate packing or smelting.

[0041] The lifting device 200 comprises a second carrier 210 and a lifting mechanism 220 connected to the second carrier 210, the lifting mechanism 220 comprising a first driving member, for example, a motor, a hydraulic cylinder or a pneumatic cylinder, etc., and a taking and placing member 222, for example, a magnetic lifting tool, a claw hook or a clamp, etc., the second carrier 210 being detachably connected to the top of the first carrier 110 through screw connection, bolt connection or magnetic attraction connection, etc., the taking and placing member 222 being capable of moving to the processing device 100 to carry radioactive waste under the driving of the first driving member, the carrying of the radioactive waste by the taking and placing member 222 including but not limited to pose adjustment of the waste or transferring of the cut waste to a waste box. Taking the pose adjustment as an example, a large waste has a large volume, which is difficult to be cut into a suitable size only by cutting at a single position, therefore, during the cutting process, the waste can be turned over or shifted by the lifting device 200 to fully divide the waste, so that the embodiment can process a waste with a larger volume, thereby improving the practicability of the workstation of the embodiment, that is, a variety of wastes can be processed through one workstation, without the need to set multiple workstations in the factory building in a targeted manner, thereby reducing the factory building space occupancy.

[0042] In the embodiment, the lifting device 200 comprises a second carrier 210 and a lifting mechanism 220, the lifting mechanism 220 is installed on the second carrier 210, the second carrier 210 can be installed on the top of the first carrier 110 of the processing device 100, the second carrier 210 and the first carrier 110 both have a certain height to support the lifting mechanism 220 at a sufficient height, and the height of the second carrier 210 or the first carrier 110 can be relatively lower than that of the prior art. Therefore, when the workstation of the embodiment needs to be transported out of or into the factory building, the lifting device 200 is detached from above the processing device 100, so that the transfer of the workstation of the embodiment is more simple, and the space in the factory building is avoided. Especially for some low factory buildings, the access channel is relatively smaller, so large equipment is usually transported into the factory building in a split form, for example, the workstation in the prior art, the lifting mechanism 220 is directly installed on the first carrier 110 of the processing device 100, and the first carrier 110 needs to have a sufficient height to make the lifting mechanism 220 above the processing module. Taking the first carrier 110 as a box structure, if the lifting mechanism 220 is directly installed in the box, the box needs to have a sufficient height to make the lifting mechanism 220 above the processing module. Therefore, when it is transported to a low factory building, the box needs to be split and then transported into the factory building for assembly. Since the assembly is relatively complicated, the workstation will not be moved out of the factory building after assembly except for special cases, so the space in the factory building is occupied after the waste treatment is completed. The detachable lifting device 200 of the embodiment can effectively improve this problem.

[0043] Further, in order to make the workstation of the embodiment more easily transported, the lifting device 200 and the processing device 100 are both provided with adjustable walking mechanisms, the walking mechanisms comprise walking wheels, the walking wheels can move up and down, and specifically, the walking wheels are moved upward to make the walking wheels not lower than the bottom of the first carrier 110 when the workstation is in a working state, so that the bottom of the first carrier 110 is grounded, thereby improving the stability of the workstation. When the workstation needs to be moved, the walking wheels are moved downward, and the first carrier 110 is lifted to make the first carrier 110 off the ground, so that the workstation can be more easily moved by the walking wheels.

[0044] In addition, when the workstation is not working, the lifting device 200 can also be detached for other uses, thereby improving the practicality of the workstation of the embodiment. Meanwhile, after the lifting device 200 is detached, other articles can be placed on the top of the processing device 100, or even other workstations are stacked on the top, thereby fully utilizing the vertical space in the factory building.

[0045] Referring to FIG. 2, FIG. 2 is a structural schematic diagram of a second radioactive waste treatment workstation according to an embodiment of the present application. In some embodiments, the treatment module includes a cutting mechanism 120 connected to the first carrier 110. The cutting mechanism 120 is not limited to being provided as a band saw, a circular saw, a diamond string, a laser cutting machine, a plasma cutting machine, or a flame cutting machine, etc. The treatment device 100 further includes a rotating mechanism 130, which includes a second driving member 131 and a rotating table 132. The rotating table 132 is used to support the radioactive waste, and the second driving member 131 is connected to the rotating table 132 to drive the rotating table 132 to rotate. It can be understood that for the cutting head 121 of the band saw, the circular saw, the diamond string, etc., the position of the cutting head 121 on the equipment is fixedly provided. It is difficult to achieve multi-angle adjustment of the waste by using only the hoisting device 200, so that the cutting head 121 is difficult to achieve multi-angle cutting of the waste. Therefore, it is difficult to complete the cutting of some specific waste with a larger volume. However, the present embodiment can effectively improve this problem. When the waste is treated by using the workstation of the present embodiment, the waste is placed on the rotating table 132. The rotating table 132 can drive the waste to be adjusted in angle, so that the waste can be cut at multiple angles. In combination with the movement and overturning of the hoisting device 200, the waste can be more fully cut. Thus, the workstation of the present embodiment can treat more different types of waste, i.e., one workstation can cut multiple types of waste, so that it is not necessary to provide multiple workstations in the factory building, thereby reducing the occupied space in the factory building.

[0046] Referring to FIG. 2, on the basis of the above-mentioned embodiment, the cutting mechanism 120 comprises a cutting head 121, for example, a non-contact cutting head 121 such as a laser or a plasma, for non-contact cutting of the radioactive waste, and the processing device 100 further comprises a mechanical arm 122, and the cutting head 121 is connected to the mechanical arm 122, so that the cutting head 121 can be rotated at multiple angles in space. Specifically, it can be known that the use of the rotating table 132 can adjust the waste at multiple angles in the horizontal direction, so as to realize the cutting of the waste with a larger volume, but for the waste with a complex structure, it is still difficult to effectively cut it only by adjusting the horizontal angle. In addition, for some waste with a complex structure, it also needs to selectively cut the parts in sequence during the cutting process. However, due to the fixed position of the cutting head 121 such as a band saw, a circular saw, and a diamond rope on the equipment, it can only cut from the edge of the waste according to the set direction, and cannot selectively cut and cannot be adjusted at multiple angles in space. Based on this, in order to further improve the practicability of the workstation of the present embodiment, in the present embodiment, the cutting head 121 is a non-contact cutting head 121, which is installed on the mechanical arm 122, and the cutting angle of the cutting head 121 and the cutting sequence of the parts can be adjusted by the mechanical arm 122, so that the workstation can cut more complex waste, and the practicability of the workstation is further improved. Thus, on the one hand, the workstation can be transferred to different workshops according to the needs, avoiding the workstation to be idle in the workshop and occupy space, and on the other hand, one workstation can cut many different wastes, so that many workstations do not need to be set in the workshop, thereby reducing the occupied space of the workshop.

[0047] It can be understood that a certain amount of radioactive aerosol and dust will be generated during the operation of the workstation. If the first carrier 110 and the second carrier 210 are of an open structure, other equipment in the environment will be contaminated to form new radioactive waste, which will further occupy the space in the factory building. Therefore, referring to FIG. 3 and FIG. 4, FIG. 3 is a structural schematic diagram of a third radioactive waste treatment workstation according to an embodiment of the present application, and FIG. 4 is a structural schematic diagram of the first box and the second box after the partial side walls are hidden. In some embodiments, the handling device 100 and the hoisting device 200 are arranged in a closed space to prevent radioactive substances from leaking out, which not only avoids the pollution of external equipment to form new radioactive waste, but also reduces the radiation dose of workers. Specifically, in the present embodiment, the first carrier 110 includes a first box 111 and a first door body. The first box 111 has a first accommodating cavity 1111 and a first docking port 1112. The first box 111 is not limited to a structure with a space inside, such as a container. The processing module is arranged in the first accommodating cavity 1111. The first docking port 1112 is located at the top of the first box 111 and is communicated with the first accommodating cavity 1111. The first door body is movably connected to the first box 111 and is used to selectively close and open the first docking port 1112. For example, the first door body is arranged as a sliding door, a swing door or a rotating door. By stretching, moving or rotating the first door body, the first docking port 1112 can be shielded or opened. In addition, the first door body can be detachably connected to the first box 111 by screw connection, pin connection or the like. When the first docking port 1112 needs to be opened, the first door body is directly detached. The second carrier 210 includes a second box 211 and a second door body. The second box 211 has a second accommodating cavity 2111 and a second docking port 2112. The second docking port 2112 is located at the bottom of the second box 211 and is communicated with the second accommodating cavity 2111. The second door body is movably connected to the second box 211 and is used to selectively close or open the second docking port 2112. Similarly, the second door body is arranged as a sliding door, a swing door or a rotating door. By stretching, moving or rotating the second door body, the second docking port 2112 can be shielded or opened. In addition, the second door body can be detachably connected to the second box 211 by screw connection, pin connection or the like. When the second docking port 2112 needs to be opened, the second door body is directly detached. The first docking port 1112 is aligned with the second docking port 2112. The taking and placing part 222 can pass through the second docking port 2112 and the first docking port 1112 to extend into the first accommodating cavity 1111. Therefore, when the waste is treated in the workstation of the present embodiment, the leakage of radioactive substances can be prevented, so that new radioactive waste is not introduced into the factory building.

[0048] Referring to FIG. 4, in some embodiments, the first box 111 has an inlet 1113 and an outlet 1114 arranged oppositely, the cutting mechanism 120 is located between the inlet 1113 and the outlet 1114, and the processing device 100 further comprises a horizontal moving mechanism 150, such as a horizontal rail, a slide rail, or a screw rod, etc., which is used to move the waste from the inlet 1113 to the cutting mechanism 120 for cutting, and then to the outlet 1114 after cutting, without manual carrying, thereby reducing the radiation dose received by the workers. For example, the horizontal moving mechanism 150 comprises a placing table 151 which can be directly used to place the waste, and the placing table 151 is capable of moving between the outlet 1114 and the inlet 1113. When the processing device 100 comprises the rotating mechanism 130, the rotating mechanism 130 is connected to the horizontal moving mechanism 150, and the horizontal moving mechanism 150 drives the rotating mechanism 130 to move between the inlet 1113 and the outlet 1114, thereby driving the waste to move from the inlet 1113 to the outlet 1114.

[0049] On the basis of the above-mentioned embodiments, the workstation further comprises an isolation layer having anti-radiation performance, which is detachably arranged in the first accommodating cavity 1111 by means of hanging, bonding, lapping, etc., and covers the side wall of the first accommodating cavity 1111. Specifically, the isolation layer comprises but is not limited to an isolation coating (such as a gel), an isolation adhesive paper, or a curtain, etc., and can be conveniently replaced and cleaned after each completion of the waste treatment task, thereby greatly reducing the difficulty of removing the workstation of the present embodiment, so that the workstation can be more conveniently removed from the factory building, thereby avoiding the occupation of space in the factory building by the idle workstation. Similarly, in some embodiments, the isolation layer is detachably arranged in the second accommodating cavity 2111 and covers the side wall of the second accommodating cavity 2111, which will not be described here again.

[0050] Referring to FIGS. 5-7, FIG. 5 is a structural schematic diagram of a processing device in a fourth radioactive waste treatment workstation according to an embodiment of the present application, FIG. 6 is a structural schematic diagram of an isolation box in FIG. 5, and FIG. 7 is a sectional view of FIG. 6. In some embodiments, the processing module includes an isolation box 160 (as shown in FIG. 5), which includes a third box body 161 and a third door body 162. The third box body 161 has a third accommodating cavity 1611 and an inlet and outlet port 1612 (as shown in FIG. 7). The inlet and outlet port 1612 is located at the top of the third box body 161 and communicates with the third accommodating cavity 1611. The third door body 162 is movably connected to the third box body 161 and is used to selectively close and open the inlet and outlet port 1612. At least a portion of the third door body 162 is a high light transmission structure, such as high light transmission glass, nanofiber, or ETFE (ethylene tetrafluoroethylene copolymer) film, etc. The processing module further includes a cutting mechanism 120, which includes a cutting head 121. The cutting head 121 is a laser cutting head 121. The laser emitted by the cutting head 121 can be irradiated into the third accommodating cavity 1611 through the high light transmission structure. The cutting head 121 can move relative to the isolation box 160 along a first direction to enable the cutting head 121 to cut waste. The first direction is, for example, the moving direction of the isolation box 160 or the moving direction of the cutting head 121. As described in the above embodiments, the processing device 100 further includes a horizontal moving mechanism 150. The isolation box 160 is connected to the horizontal moving mechanism 150. The horizontal moving mechanism 150 can drive the isolation box 160 to move from the inlet 1113 to the outlet 1114 of the first box body 111. Alternatively, the cutting head 121 is connected to a mechanical arm 122. The mechanical arm 122 can drive the cutting head 121 to move along the first direction.

[0051] Specifically, as known from the above, during waste treatment, radioactive aerosols or dusts will be generated, and thus the radioactive substances generated during operation will be attached to the equipment of the workstation itself, resulting in the equipment of the workstation itself forming new radioactive waste and occupying the plant space, and the embodiment can effectively improve this problem. The embodiment is provided with the isolation box 160, during operation, the waste is placed into the third containing cavity 1611 from the access opening 1612, and the access opening 1612 is closed by the third door body 162, so that the third containing cavity 1611 forms a closed operation space, and the laser generated by the cutting head 121 can be irradiated into the third containing cavity 1611 through the high-transmittance structure provided on the third door body 162 to cut the waste, so that the waste is cut in a closed environment. If the waste needs to be lifted, the workstation is allowed to stand for a period of time, and after the radioactive substances fall to the bottom of the third containing cavity 1611, the access opening 1612 is opened, and the taking and placing piece 222 of the lifting device 200 is extended into the third containing cavity 1611 through the access opening 1612 to move the waste. As can be known, in the embodiment, except for the isolation box 160, the other equipment of the workstation will not be contaminated by radioactive substances, thereby greatly reducing the generation of new waste and in turn reducing the plant space occupied by the waste. In addition, in the embodiment, since only the isolation box 160 is contaminated, after the operation is completed, only the isolation box 160 needs to be treated, and the treatment of the isolation box 160 includes but is not limited to being directly treated as waste, so that the workstation of the embodiment can be quickly withdrawn, thereby avoiding the occupation of the plant space by the workstation after the operation is completed. Further, when the first bearing member 110 and the second bearing member 210 are both in the box structure, the isolation box 160 is used in combination with the box structure to form two radioactive isolation boundaries, improve the safety of on-site operation, and avoid radiation exposure events caused by accidental approach of personnel.

[0052] The third door body 162 is at least partially provided as a high light transmission structure, including but not limited to the third door body 162 being entirely provided as a high light transmission structure. Specifically, in order to meet the cutting requirements, the third door body 162 must be able to meet the needs of the cutting process, for example, the third door body 162 includes a light transmission piece 16212, the light transmission piece 16212 is a high light transmission structure, and the light transmission piece 16212 is a long strip-shaped structure extending along the first direction, so that the laser emitted by the cutting head 121 can be emitted into the third accommodating cavity 1611 through the light transmission piece 16212, and cut the waste along the first direction relative to the isolation box 160. Further, in order to realize the omnidirectional cutting of the waste, in some embodiments, the cutting head 121 can move along the second direction relative to the isolation box 160, the second direction is perpendicular to the first direction, and at the same time, the light transmission piece 16212 needs to meet the needs of the cutting head 121 along the first direction and the second direction. For example, the cutting mechanism 120 includes a mechanical arm 122, the cutting head 121 is connected to the mechanical arm 122, the mechanical arm 122 can drive the cutting head 121 to move along the first direction and the second direction, and the third door body 162 is entirely provided as a high light transmission structure, so that the cutting head 121 can emit laser into the third accommodating cavity 1611 when moving to any position.

[0053] Alternatively, referring to FIG. 6, in some embodiments, the third door body 162 includes a first shielding part 1621 and two second shielding parts 1622, the two second shielding parts 1622 are distributed along the second direction, the first shielding part 1621 is located between the two second shielding parts 1622, at least part of the first shielding part 1621 is a high-transmittance structure, the first shielding part 1621 and the second shielding part 1622 can move reciprocally along the second direction, and at least one second shielding part 1622 can move relative to the first shielding part 1621 along the second direction. Specifically, the first shielding part 1621 and the second shielding part 1622 are connected with driving devices, or the two second shielding parts 1622 are connected with driving devices, and the first shielding part 1621 is connected to any one of the second shielding parts 1622, so that the second shielding part 1622 drives the first shielding part 1621 to move, and at any moment during the movement, the inlet and outlet port 1612 can be shielded by the first shielding part 1621 and the second shielding part 1622 together, so that the third containing cavity 1611 is in a closed state during operation. Specifically, for example, the second shielding part 1622 is a flat plate structure, in order to ensure that the second shielding part 1622 can move to any position and shield the inlet and outlet port 1612 together with the first shielding part 1621, the sizes of the first shielding part 1621 and the second shielding part 1622 meet the following requirements: along the first direction, the size of the first shielding part 1621 is L1, the size of the second shielding part 1622 is L2, and the size of the inlet and outlet port 1612 is L3, L1+L2≥L3, therefore, no matter which limit position (the edge of the inlet and outlet port 1612) of the inlet and outlet port 1612 the first shielding part 1621 moves to on the side of the first direction, the inlet and outlet port 1612 can be shielded together with one of the second shielding parts 1622, so that the third containing cavity 1611 forms a closed space. During operation, when the cutting head 121 moves relative to the isolation box 160 along the second direction, the first shielding part 1621 moves synchronously along the second direction, and correspondingly, the two second shielding parts 1622 also move synchronously to ensure the closure of the inlet and outlet port 1612. It can be understood that in this embodiment, since the first shielding part 1621 can move along the second direction together with the cutting head 121, i.e., the high-transmittance structure can move synchronously along the second direction together with the cutting head 121, therefore, in this embodiment, the third door body 162 does not need to be a high-transmittance structure as a whole, thereby reducing the processing cost of the third door body 162.

[0054] It should be noted that the reason why at least one second shielding part 1622 can move relative to the first shielding part 1621 along the second direction is to open the inlet and outlet port 1612 through the relative movement between the second shielding part 1622 and the first shielding part 1621.

[0055] Similarly, in some embodiments, the first shielding part 1621 is movable relative to the access port 1612 along the first direction, for example, the first shielding part 1621 comprises a movable part 16211 and a light-transmitting part 16212, the movable part 16211 is a flat plate structure, the movable part 16211 is movable along the first direction, the movable part 16211 has a mounting hole, the light-transmitting part 16212 is arranged in the mounting hole, along the first direction, the size of the movable part 16211 is greater than or equal to the size of the access port 1612, so that no matter where the light-transmitting part 16212 moves to the edge of the access port 1612 in the first direction, the movable part 16211 can cross the access port 1612 along the first direction and shield the access port 1612 together with the second shielding part 1622. The movable part 16211 can be driven by a driving device, or the movable part 16211 can move with the cutting head 121, for example, in some embodiments, the first shielding part 1621 further comprises a connecting sleeve 16213, the connecting sleeve 16213 has a lumen and an upward opening, the connecting sleeve 16213 is connected to the movable part 16211, the light-transmitting part 16212 is connected to the connecting sleeve 16213 and closes the lumen of the connecting sleeve 16213, the cutting head 121 can be inserted into the connecting sleeve 16213 from the opening, so that when the cutting head 121 moves, the connecting sleeve 16213 can move together with the cutting head 121, on the one hand, the movable part 16211 adopts a non-powered configuration, which can reduce the cost; on the other hand, the consistency of the cutting head 121 and the light-transmitting part 16212 does not need to be ensured by the consistency of the work of two driving devices for driving the light-transmitting part 16212 and the cutting head 121, so that the fault tolerance of the workstation of the embodiment is higher, thereby improving the reliability of the embodiment.

[0056] Referring to FIG. 7, in some embodiments, the second shielding part 1622 is a roller shutter structure, that is, the second shielding part 1622 comprises a plurality of shielding plates, adjacent shielding plates are rotationally connected, so that the second shielding part 1622 can be arranged in a rolled state, the isolation box 160 further comprises two winding mechanisms 163, the winding mechanism 163 comprises a third driving part and a winding shaft 1631, the axis of the winding shaft 1631 is perpendicular to the second direction, each second shielding part 1622 is connected to a winding shaft 1631, the third driving part is connected to the winding shaft 1631, for driving the winding shaft 1631 to rotate, so that the winding shaft 1631 winds and unwinds the second shielding part 1622, so that the edge of the second shielding part 1622 away from the winding shaft 1631 moves back and forth along the second direction relative to the third box body 161. Specifically, from the above embodiments, if the second shielding part 1622 is arranged as a flat plate structure, both second shielding parts 1622 need to have a moving space in the second direction during work, that is, the size of the third door body 162 along the second direction is 2L2+L Iand the size of the third inlet / outlet port 1612 can be only L1+L2, so the third door body 162 needs to occupy at least L I space, and in the embodiment, the two second shielding parts 1622 can be wound on the winding shaft 1631, so as to reduce the space occupied by the second shielding parts 1622 in the first direction, and further make the structure of the isolation box 160 more compact, so as to make the structure of the workstation of the embodiment more compact and reduce the space occupied by the workstation.

[0057] Similarly, in some embodiments, the first shielding part 1621 includes a movable part 16211 and a light-transmitting part 16212, the movable part 16211 is provided in a telescopic structure, for example, the movable part 16211 is provided in a foldable structure or a flexible structure, and during the movement of the connecting sleeve 16213 driven by the cutting head 121, the connecting sleeve 16213 can drive the movable part 16211 to extend or retract, so as to reduce the space occupied by the movable part 16211 in the first direction, thereby reducing the space occupied by the workstation.

[0058] Referring to FIG. 6, in some embodiments, the first shielding part 1621 further includes an observation window 16214, the observation window 16214 is a visual structure, through which the cutting of the waste can be observed, and the cutting trajectory can be adjusted accordingly. Specifically, for example, the processing device 100 further includes a camera, which is arranged at the observation window 16214, and the camera can capture the cutting of the waste in real time through the observation window 16214, and the operator can adjust the cutting trajectory by adjusting the movement of the mechanical arm 122 based on the picture captured by the camera, so that the waste can be fully cut.

[0059] Referring to FIG. 5, in some embodiments, the processing device 100 further includes a negative pressure filtering mechanism 170, which is communicated with the third accommodating cavity 1611, for sucking and filtering the air in the third accommodating cavity 1611, so that the dust, aerosol and other particles mixed in the air are discharged out of the third accommodating cavity 1611, which can avoid the dust from gathering on the observation window 16214, so as to ensure the visibility of the observation window 16214, and on the other hand, prevent the formation of positive pressure in the isolation box 160, effectively reducing the risk of radioactive material leakage.
