Description

Technical Field

[0001] The invention relates to the technical field of nuclear fusion, and in particular to an assembly method and assembly tooling for a nuclear fusion device. Background Art

[0002] It is pointed out in the relevant technology that how to solve the energy problem is one of the severe problems that all countries have to face at this stage. Nuclear fusion energy is a new type of clean energy, and controlled nuclear fusion is an important field that countries around the world are actively researching and exploring. Controlled nuclear fusion uses a fusion device called Tokamak to magnetically confine high-temperature plasma, so that the plasma undergoes fusion reactions in a vacuum chamber, releasing huge amounts of energy, which is then converted into energy and finally used by humans. The fusion device is composed of thousands of parts, and its core components are the superconducting magnet system and the vacuum chamber system. The superconducting magnet system is equipped with a central solenoid magnet, a toroidal field magnet, and a poloidal field magnet. The central solenoid magnet is used to provide the volt-seconds required to generate, establish, and maintain the plasma current through current changes. The poloidal magnetic field generated by the poloidal field magnet is used to control the cross-sectional shape and position balance of the plasma. The toroidal magnetic field generated by the toroidal field magnet is used to ensure the macroscopic overall stability of the plasma. The toroidal magnetic field and the poloidal magnetic field generated by the plasma current are used to confine the plasma. The vacuum chamber system is used to provide a clean ultra-high vacuum environment for the stable operation of plasma and reduce the nuclear heat deposition of neutrons produced by fusion on the superconducting magnet and the pollution to the environment. The gap between the vacuum chamber and the toroidal field magnet is very narrow, and the ring-shaped installation of the vacuum chamber sector and the toroidal field magnet is an important part of the construction of the fusion device.

[0003] The production cycle of vacuum chamber sectors and toroidal field magnets is relatively long. During the assembly of nuclear fusion devices, the arrival time of vacuum chamber sectors and toroidal field magnets continues to be relatively long, and the synchronization of arrival is difficult to grasp. In the existing assembly method, the vacuum chamber sectors and toroidal field magnets are first preassembled into standard sector components in the pre-installation hall outside the main engine hall, and then hoisted as a whole. This installation method is relatively strict on the delivery time of each component. All sub-components in the standard sector must be gathered and pre-installed before the main engine ring assembly work can be carried out. The assembly cycle is long and the efficiency is low.

[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0045] Reference below Figure 1-Figure 13 The following describes an assembly method of a nuclear fusion device according to an embodiment of the first aspect of the present invention.

[0046] like Figure 1 , Figure 3 , Fig.11 and Fig.12 As shown, according to the assembly method of the nuclear fusion device of the first aspect of the embodiment of the present invention, the nuclear fusion device includes a vacuum chamber and a toroidal field magnet, the vacuum chamber is formed by a plurality of vacuum chamber sectors spliced ​​together in the circumferential direction, the plurality of vacuum chamber sectors include at least one first sector 10 and at least one second sector 11, the toroidal field magnet is formed by a plurality of magnetic field monomers spliced ​​together in the circumferential direction, the magnetic field monomers include at least one first magnet 12 and at least one second magnet 13, the first sector 10 is suitable for being mounted with the first magnet 12, and the second sector 11 is suitable for being mounted with the second magnet 13.

[0047] Assembly methods include:

[0048] S1, outside the host hall 100, the first sector 10 and the first magnet 12 are assembled to form a standard sector 14, the standard sector 14 is moved to the host hall 100, and the second sector 11 and the second magnet 13 are assembled in the host hall 100;

[0049] S2. In the mainframe hall 100, a plurality of vacuum chamber sectors are spliced ​​together in the circumferential direction, and a plurality of magnetic field monomers are spliced ​​together in the circumferential direction.

[0050] Among them, the main engine hall 100 is the site where the nuclear fusion device is assembled and subsequent nuclear fusion work is carried out. During the assembly process, the second sector 11 can be hoisted into the main engine hall 100 first, or the standard sector 14 can be hoisted into the main engine hall 100 first. It should be noted that when the standard sector 14 is hoisted into the main engine hall 100 first, it is necessary to reserve operating space for installing the second magnet 13 at at least one end of the circumference of the second sector 11.

[0051] In actual production, the manufacturing process of the magnetic field monomer is relatively complicated and the production time is relatively long. The vacuum chamber sectors will arrive first. During the assembly process, the second sector 11 can be hoisted into the main engine hall 100 first, and the second magnet 13 and the second sector 11 that have arrived can be assembled in the main engine hall 100. At the same time, the first magnet 12 and the first sector 10 that have arrived can be assembled outside the main engine hall 100 to form a standard sector 14, and the standard sector 14 can be hoisted into the main engine hall 100. After the subsequent magnetic field monomers arrive, the second sector 11 that has not been matched in the above process can be assembled with the second magnet 13 in the host hall 100. At the same time, the first sector 10 that has not been matched in the above process can be assembled with the first magnet 12 outside the host hall 100 to form a standard sector 14, and the standard sector 14 can be hoisted into the host hall 100. Then, multiple vacuum chamber sectors and multiple magnetic field monomers can be spliced ​​in the circumferential direction in the host hall 100 to complete the ring closing operation of the vacuum chamber and the annular factory magnet. In this way, the arrival time of the vacuum chamber sectors and the magnetic field monomers can be reasonably utilized.

[0052] According to the assembly method of the nuclear fusion device of the first embodiment of the present invention, during the assembly of the nuclear fusion device, the first sector 10 and the first magnet 12 are assembled outside the host hall 100 to form a standard sector 14 and the second sector 11 and the second magnet 13 are assembled inside the host hall 100, which can be carried out simultaneously, thereby making rational use of the arrival time of the vacuum chamber sectors and the magnetic field monomers and improving the assembly efficiency of the nuclear fusion device.

[0053] In some embodiments of the present invention, both the first sector 10 and the second sector 11 are multiple, for example, the first sector 10 can be two, three, four or six, the second sector 11 can be two, three, four or six, and the second sector 11 and the standard sector 14 are arranged alternately in the circumferential direction of the vacuum chamber. In this way, during the assembly process, the second sector 11 is first hoisted to the host hall 100 and the second magnet 13 is assembled on the second sector 11. Both ends of the second sector 11 in the circumferential direction have more operating space, thereby reducing the difficulty of assembly and further improving the assembly efficiency.

[0063] During the process of splicing the standard sector 14 with the two adjacent second sectors 11 and the second magnet 13, the position of the first sector 10 can be adjusted by adjusting the position of the sector pull rod 82 on the third lifting beam 81, and the position of the first magnet 12 can be adjusted by the magnet adjustment assembly, thereby realizing the splicing of the first sector 10 in the standard sector 14 and the adjacent second sectors 11, and the splicing of the first magnet 12 in the standard sector 14 and the adjacent second magnet 13.

[0064] Wherein, after all the second sectors 11 and the second magnets 13 are assembled, the standard sectors 14 are moved in sequence between two adjacent second sectors 11;

[0065] Alternatively, after the two adjacent second sectors 11 are assembled with the corresponding second magnets 13 , the standard sector 14 may be moved in sequence between the two second sectors 11 , and then the above operation may be repeated.
