Description

Technical Field

[0001] This invention relates to the field of hot chamber technology for isotope production, and in particular to a target hot chamber system for isotope production and its operation process. Background Technology

[0002] A hot chamber is a shielded enclosure used for conducting high-radioactivity experiments and operations. Its main purpose is to prevent the leakage of radioactive materials and to protect operators from radiation damage. The hot chamber is typically equipped with remote operating devices such as master-slave robotic arms for performing appropriate technological operations on high-radioactivity materials.

[0003] With the development of modern medicine and nuclear medicine technology, medical radioisotopes are playing an increasingly important role in disease diagnosis and clinical treatment. However, the mass production capacity of alpha radioisotopes has not been effectively improved, becoming a major constraint on the widespread adoption of alpha-targeted therapy. Breakthroughs in high-power accelerator irradiation production technology are key to solving the problem of scarce medical isotope supply.

[0004] In high-power beam irradiation production, the beam's thermal power needs to be distributed over a larger area to meet the target cooling requirements. For proton beam currents of a few milliamperes, dozens or even hundreds of target plates need to be rationally arranged in space to maximize heat exchange efficiency. Chinese patent application number 202510261285.2 discloses a target device for isotope production. This device loads target plates in an array within a module, and through the side-by-side arrangement of multiple modules, multiple target plates are arranged in three-dimensional space, significantly increasing the heat exchange area and thus providing the equipment foundation for mass production of isotopes.

[0005] However, the target station hot chamber systems used in the existing technology for producing alpha isotopes such as Ra-223 and Ac-225 are mainly arranged around a single target or a series target scheme. The operating efficiency of the feeding and unloading and target loading and unloading systems is low, which cannot meet the high requirements of large-scale mass production mode for beam intensity, target replacement efficiency and safety protection.

[0006] Therefore, it is urgent to develop a target station hot chamber system with high operating efficiency, so that the target station hot chamber system can be matched with the above-mentioned target device, so as to use high-energy, high-current beams to irradiate a large number of target sheets simultaneously, greatly improve the production efficiency of isotopes, and thus achieve a breakthrough in high-power accelerator irradiation production technology.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0033] In an embodiment of the present invention, a target station hot chamber system for isotope production is described.

[0034] like Figure 1 and Figure 2 As shown, the target station hot chamber system mainly includes an operating hot chamber, an irradiation chamber, and a target vehicle passage. The operating hot chamber is used to execute the target loading, target unloading, and material unloading processes. The irradiation chamber is used to execute the irradiation process.

[0035] The target vehicle passage connects the irradiation chamber and the operating hot chamber. The target vehicle passage includes a track and a target vehicle. The track extends from the operating hot chamber to the irradiation chamber, and the target vehicle transports the target container along the track.

[0036] The reason is that when a high-power beam is used to irradiate a target, the beam produces an extremely high radiation dose after hitting the target. The radiation dose around the irradiation point during irradiation is 5 to 6 orders of magnitude higher than the induced radiation dose after irradiation stops. Therefore, it is necessary to divide the internal space of the hot chamber into different areas and use thicker shielding materials to separate the areas where beam irradiation is performed, thereby ensuring that the equipment in the hot chamber does not fail rapidly due to strong radiation.

[0037] From one end furthest from the irradiation chamber to the other closest, the operating hot chamber is sequentially equipped with four workstations: a target plate operating platform, a hoisting area, a target vehicle maintenance area, and a target container and component assembly / disassembly area. Each workstation is equipped with a viewing window and a master-slave robotic arm.

[0038] Furthermore, the target station hot chamber system also includes a feed glove box and a feed channel.

[0039] The feeding glove box is located outside the operating hot chamber. The feeding channel is located between the feeding glove box and the target plate operating table for receiving new target plates.

[0040] Furthermore, the bottom of the target plate operating table is provided with a double-cover docking structure and a discharge channel for rotating out the irradiated target plate.

[0041] Furthermore, the operating hot chamber is also equipped with a target container temporary storage pit and a target component temporary storage pit to reduce the frequency of solid waste transfer.

[0042] Furthermore, a beam window is provided at the interface between the irradiation chamber and the beam channel to isolate the beam vacuum environment from the air environment of the irradiation chamber.

[0043] Furthermore, the hoisting area is equipped with a powered robotic arm, mounted on top of the operating hot chamber, for gripping and transferring target containers and target components.

[0044] This is because when the target container is transferred from the irradiation chamber to the operating hot chamber for target replacement, the radiation dose around the target container can still reach approximately 10. 8 The radiation level is μSv / h, which is relatively high. Therefore, operations in the operating hot chamber still require remote control using master-slave manipulators, powered manipulators, robots, or other power tools to ensure the safe and reliable disassembly and installation of target components and target pieces.

[0045] Furthermore, a hoisting inspection and maintenance hole is provided directly above the hoisting area for the inspection and maintenance of the power robot, and for the transfer of equipment and parts in and out.

[0046] Specifically, the target station hot chamber system includes one irradiation chamber, one operating hot chamber, one discharge channel, and one feed glove box. The irradiation chamber and the operating hot chamber are connected by a target vehicle channel.

[0047] The target cart can transport the target container to the irradiation position within the irradiation chamber along a track. Once irradiation is complete, the target cart retracts, and the target container is towed to the operating station within the operating hot chamber. The feed glove box and feed channel are centrally located on the side of the operating hot chamber furthest from the irradiation chamber. The feed glove box is in the front area, and the discharge channel is in the rear area. From the feed glove box side, there are four zones in sequence: the target plate operating platform, the hoisting area, the target cart maintenance area, and the target container and component assembly / disassembly area.

[0048] At the irradiation position in the irradiation chamber, a high-current, high-power particle beam rapid point scanning method disclosed in Chinese patent application number 202111570196.4 is used to control the beam to rapidly scan multiple rows and columns of target points on the target container. At each target point, the beam penetrates multiple target sheets arranged in series. Thus, dozens or even hundreds of target sheets can be irradiated in a single production cycle. A beam window is arranged at the interface between the irradiation chamber and the beam channel to isolate the beam vacuum environment and the air environment of the irradiation chamber.

[0049] like Figure 1 As shown, the operating hot chamber has four workstations, from left to right: target plate operating platform, hoisting area, target vehicle maintenance, and target container and component assembly / disassembly. Each workstation is equipped with a viewing window and a master-slave robotic arm for easy observation and assisted operation.

[0050] like Figure 2 As shown, a lifting inspection and maintenance opening is provided directly above the lifting area for the inspection and maintenance of the power robot, and for the transfer of equipment and parts. The clear passage dimension of the lifting inspection and maintenance opening is... 1.1 meters. A square equipment mounting hole is provided on the top of the target vehicle, with a clear passage size of 2m × 1.5m, for the entry and exit of the target vehicle and large equipment such as the main power arm module and tracks.

[0051] The operating hot chamber has a feeding channel on its side wall that connects to the feeding glove box for receiving new target wafers. The bottom of the hot chamber has a target container storage pit and a target assembly storage pit for temporary storage of the target container and target assembly, respectively. A shielded door is also provided on one side of the rear area for maintenance personnel to enter and exit.

[0052] Furthermore, a double-cover docking structure and a discharge channel are installed at the bottom of the target plate operating table. The table surface is equipped with the double-cover docking structure, target component hanger, and an electric robotic arm with a fixed base. The double-cover docking structure is used for target plate discharge, the target component hanger is used to hold and limit the target components transferred by the powered arm, and the table robotic arm is responsible for inserting the target plate into the target component or removing it from the target component and placing it into the inner cylinder of the double-cover docking structure.

[0053] A small robotic arm with a fixed base is used to perform precise operations such as loading and unloading target pieces and unloading. The tabletop robotic arm, combined with the limiting design of the target component hanger, can meet the high-precision requirements of target piece insertion. The automation capability and streamlined design can greatly improve the overall efficiency of loading and unloading target pieces and meet the high-frequency operation requirements of mass production.

[0054] The specific structure of target assembly 2 and target assembly bracket 3 is as follows: Figures 4 to 7 As shown. The target assembly 2 includes a target frame 12 and a target assembly clamping six-sided column 21. The target assembly bracket 3 includes a target assembly limiting hole 31 and a target assembly limiting base 32.

[0055] Each target assembly 2 has four irradiation target points arranged from top to bottom. At each target point, four target pieces 1 are placed in parallel from front to back, so that 16 target pieces 1 can be inserted into a single target assembly 2. Each target container is arranged with four target assembly 2 slots, that is, 64 target pieces can be produced in a single irradiation.

[0056] Once the target container reaches its irradiation damage lifetime, it needs to be removed and disposed of as solid waste. To reduce the difficulty of transferring high-level radioactive solid waste, the operating hot chamber is equipped with a target container temporary storage pit for cooling the high-level target container. Once its radioactivity has decayed to a lower level, it can be transferred out of the operating hot chamber.

[0057] By setting up multiple temporary storage stations, not only can the frequency of solid waste transfer be reduced and the decay cooling time extended, but multiple new target containers can also be stored for backup, enabling the replacement and transfer of old and new target containers within the hot chamber and avoiding the difficulties of large materials entering and leaving the hot chamber. The irradiation life of a single target container can reach 3 years, and with 3 temporary storage pits and a total of 6 temporary storage stations, the internal circulation time of the target containers can reach 18 years. Considering that the actual equipment cannot be continuously irradiated, on-site storage of target containers can be basically achieved throughout the entire lifespan.

[0058] Both the target component storage pit and the target container storage pit are equipped with shielding covers to control the dose equivalent in the hot chamber during maintenance and repair. Unlike conventional above-ground storage containers, the target component storage pit and the target container storage pit in this application not only utilize the concrete below ground as a circumferential shield, avoiding the waste of space in above-ground heavy shielding containers, but also reduce the lifting height of the stored objects, preventing interference from movement in the hot chamber and visual obstruction.

[0059] The core process flow within the operating hot chamber primarily relies on automated operation using powered robotic arms and tabletop robotic arms to meet the high-frequency operation requirements of large-scale irradiation production. The powered robotic arms mainly operate through direct gripping and electric turning, requiring a positioning accuracy of ±1mm. Target insertion and removal require a positioning accuracy within ±0.2mm, which the tabletop robotic arm with a fixed base can satisfy. The master and slave robotic arms serve as auxiliary and backup methods, responsible for auxiliary operations during inspection and maintenance, as well as remedial and source removal operations in case of unexpected conditions.

[0060] In this embodiment, the target station hot chamber system is equipped with an operating hot chamber and an irradiation chamber. The operating hot chamber includes four workstations: a target plate operating platform, a hoisting area, a target vehicle maintenance area, and a target container and component assembly / disassembly area. Compared with multiple small hot chambers connected in series, it has stronger functionality, fewer connection links, higher equipment and space utilization, and stronger maintainability. It can better meet the requirements of isotope mass production for various aspects such as target loading, target unloading, material feeding and unloading automation, and safety protection. The target station hot chamber system can use a high-energy, high-current proton accelerator to irradiate the target plates in the target container, thereby significantly improving production efficiency and significantly reducing overall costs.

[0061] Based on the above embodiments, another embodiment of the present invention introduces a target station hot chamber system for isotope production.

[0062] like Figure 2 and Figure 3 As shown, the power robot is located in the hoisting area. The power robot includes a main load-bearing platform, a trolley assembly, a telescopic sleeve 6, an electric hoist, a robotic arm 5, an electric turning tool head 4, and a control device, etc.

[0063] The main support platform consists of a walking mechanism, a mobile platform, a frame, drive wheels, a drive unit, limit switches, and a derailment protection device. It is used to install components such as the trolley assembly, robotic arm 5, and robotic arm power station, and to move within a certain range above each hot chamber along the running track.

[0064] The traveling wheels of the traveling mechanism are matched with the running track. The drive motor is a servo motor with an encoder and a brake, which facilitates precise position control and timely braking of the main load-bearing platform, improving the safety of the entire traveling mechanism. The control device is used to drive the traveling motor to start, stop, run, and avoid obstacles. It needs to be able to be remotely controlled by the operator, allowing for high-speed, low-speed, and stopping operation along the running track.

[0065] The trolley assembly mainly consists of drive wheels, a trolley walking mechanism and drive unit, an electrical management system, actuator storage positions, a plasma generator power supply, a control system, and cable chains. The trolley assembly has two main functions: first, it serves as a mobile platform supporting the robotic arm 5 and the telescopic sleeve 6 to complete lateral movement within a certain range above the hot chamber; second, it carries the power unit, control unit, pneumatic and electrical management system, and actuator storage positions required for the robotic arm 5, telescopic sleeve 6, and the robotic arm tool head.

[0066] like Figure 3 As shown, the telescopic sleeve 6 of the power arm integrates a robotic arm 5 and a screw-tightening tool at its end. The robotic arm 5 has a horizontal lifting capacity of 150 kg and is used to grab and transfer target components and target containers. The electric screw-tightening tool is a spare and can be used to disassemble and tighten the sealing cap of the target container and the water inlet / outlet flange bolts at the bottom of the target container. The power arm trolley is equipped with a 2-ton electric hoist for hoisting the shielding cover of the target container temporary storage pit.

[0067] Furthermore, in another embodiment of the present invention, an operating procedure for a target station hot chamber system is described. This operating procedure can be applied to the target station hot chamber system described in any of the above embodiments.

[0068] The operation process mainly includes: target loading process, irradiation process, target unloading process, and material discharge process.

[0069] Furthermore, the target loading process includes: S1, controlling the powered robotic arm to transfer the target assembly to the target plate operating table, and using the fixed base small robotic arm to insert the new target plates into the target plate slots in the target assembly in sequence; S2, controlling the powered robotic arm to transfer the target assembly to the target container; S3, repeating the above steps until the target plates of the four target assemblies are loaded, and then transferring the target container to the target vehicle.

[0070] like Figure 8 As shown, the specific operation process is as follows: First, the tray containing 16 target pieces is sent into the target piece operating table in the operating hot chamber through the feeding glove box and feeding channel.

[0071] Then, control the power robot to grab an empty target assembly from the temporary storage pit, transfer it to the top of the target operation table, and place it into the limiting hole in the target assembly bracket. Horizontal limiting is achieved by relying on the top and bottom of the bracket.

[0072] Then, the robotic arm grippers on the table pick up new target pieces one by one from the target piece tray and insert them into the target piece slots in the target assembly in sequence. After inserting to half the depth, the grippers are released and retracted. After closing, the grippers are aligned with the narrow edge of the target piece and pushed in until the target piece is fully in place.

[0073] After the installation of 16 target pieces is completed, the controlled robotic arm grabs the target assembly, transfers it to the top of the target container, and inserts it into the corresponding target assembly slot according to the number.

[0074] The above operation is then repeated until all four target components are loaded. Then, the powered robotic arm grasps the target container cover and uses an electric screwdriver at the end of the robotic arm's sleeve to lock and seal the cover. Finally, the target container is pushed into the target vehicle, completing the target loading process.

[0075] The target vehicle is moved to the irradiation chamber to carry out the irradiation process: after the water, electricity, gas, ventilation and heat chamber systems are ready, beam irradiation begins.

[0076] When the beam irradiation time reaches the production requirement for a single irradiation, the beam supply is stopped, and the water circulation in the target container is maintained to remove residual heat.

[0077] After cooling for a period of time, stop water circulation and control the target vehicle to move to the operating hot chamber to carry out the target placement process: adjust the water level inside the target container to the required height, then control the screwing tool on the power robot arm to loosen the screws on the target container cover, grab the target container cover and place it on one side of the target vehicle.

[0078] The target components are extracted one by one and placed in the slots in the target component temporary storage pit. After extracting all four target components, the target loading process is completed.

[0079] Then the unloading process is executed: the target component rack, which is filled with target components, is retrieved from the target component temporary storage pit and placed on the target component operating table.

[0080] Control the robotic arm gripper on the console to perform the target removal operation in sequence. First, push the target out of the slot to 1 / 3, adjust the gripper to hold the protruding part of the target, remove the target and place it in the fixed position inside the double cover.

[0081] After removing all the target pieces from the target assembly, they are then transferred out of the operating hot chamber through the discharge channel.

[0082] Finally, the robot arm is controlled to store the empty target components into the target component temporary storage pit, and the process of unloading four target components is completed in a loop.

[0083] Furthermore, after the target loading process is completed, the unloading process can be carried out simultaneously with the irradiation process. For isotopes such as Ac-225, the irradiation time is generally around 10 days, and utilizing the irradiation time for unloading can significantly improve production efficiency.

[0084] The operational process in this embodiment utilizes the target assembly temporary storage pit to perform material unloading operations during beam irradiation, achieving large-scale target assembly circulation and small-scale target sheet circulation. This maximizes material flow efficiency and ensures the continuity of isotope production, while also simplifying the operating station and reducing maintenance and source removal difficulties. The target container temporary storage pit allows for the replacement and transfer of new and old target containers within the operating hot chamber, avoiding the difficulties associated with the removal of highly radioactive solid waste and significantly improving production efficiency.
