Description

Technical Field

[0001] This invention relates to the field of nuclear fusion equipment construction technology, and in particular to a method for assembling the blanket of a fusion reactor. Background Technology

[0002] The fusion reaction in a nuclear fusion reactor occurs within a toroidal vacuum chamber. During operation, the blanket must withstand neutron bombardment to provide fuel for fusion and receive a large amount of thermonuclear radiation. Therefore, the blanket is one of the important core components of a fusion reactor, and the successful assembly of the blanket is a crucial step in the construction of a nuclear fusion reactor.

[0003] Existing cladding assembly methods typically involve first closing the vacuum chamber into a ring, then hoisting the cladding through the upper window, or setting up tracks in the middle window to deliver the cladding components into the vacuum chamber for assembly. These existing assembly methods impose certain requirements on the design dimensions of the cladding and the windows, and since all components are transported through the windows, the assembly efficiency of the cladding is poor.

[0059] The assembly of the blanket is divided into two stages: the near-ring vacuum chamber stage and the annular vacuum chamber stage. In the near-ring vacuum chamber stage, because the second annular lobe is not yet closed, an assembly platform and transport fixtures can be built within the near-ring vacuum chamber. Furthermore, components can be directly hoisted from the second annular lobe location, eliminating the need to send components in through the windows on the annular lobe, thus greatly improving the blanket assembly efficiency. After installing the first part of the blanket, the second annular lobe is closed, and the blanket is then assembled onto the inner wall of the last second annular lobe. This results in high overall assembly efficiency, fewer restrictions on the structural design of the fusion reactor, and a wider range of applications. Attached Figure Description

[0075] Please see Figures 1 to 3 The cladding 30 is installed on the inner wall of the vacuum chamber; the vacuum chamber includes n-1 first annular lobes 11 and 1 second annular lobe 40.

[0076] A fusion reactor blanket assembly method according to an embodiment of the present invention includes:

[0077] S1: The first annular lobes 11 are connected in a closed loop to form a near-closed loop vacuum chamber 10;

[0078] S2: An assembly platform 20 is built inside the near-ring vacuum chamber 10. The assembly platform 20 includes a transport tooling 21.

[0079] S3: Hoist each component of the cladding 30 to the transport fixture 21 to transport it to the preset installation position, and install the cladding 30 on the inner wall of each first annular petal 11;

[0080] S4: Remove the assembly platform 20 and connect the second annular lobe 40 to form an annular vacuum chamber;

[0081] S5: Construct a transport track 50 through the central window of the annular vacuum chamber, and assemble auxiliary tooling 51 inside the annular vacuum chamber;

[0082] S6: Transport each component of the cladding 30 to the interior of the auxiliary tooling 51 via the transport track 50, and install the cladding 30 on the inner wall of the second annular petal 40;

[0083] S7: Remove auxiliary tooling 51 and transport track 50.

[0084] The assembly of the cladding 30 within the vacuum chamber is divided into two construction stages. The first stage involves the first annular lobes 11 being joined together to form a near-closed-ring vacuum chamber 10. Since the second annular lobes 40 are not yet closed, a fan-shaped notch 15 is formed at the position of the second annular lobes 40 in the near-closed-ring vacuum chamber 10. This allows for the installation of the assembly platform 20 and the transport fixtures 21, facilitating the hoisting of various components. Furthermore, by setting multiple transport fixtures 21 on the assembly platform 20, the cladding 30 at multiple different positions can be installed simultaneously, greatly improving the installation efficiency of the cladding 30. After the cladding 30 is assembled within the first annular lobes 11, the second stage begins. The second annular lobes 40 are connected to the first annular lobes 11 to complete the closure, forming a complete annular vacuum chamber. In this stage, only the inner side of the second annular lobes 40 needs to be assembled with the cladding 30. By constructing a transport track 50 at the central window position of the second annular lobes 40, in conjunction with auxiliary fixtures 51, the inner wall of the second annular lobes 40 can be assembled with the cladding 30. The integral blanket 30 has high assembly efficiency and is suitable for use in fusion reactors of various sizes. It has a wider range of applications, fewer restrictions on the structural design of fusion reactors, and is more conducive to the construction and realization of the designed structure.

[0085] Further, in step S1, the first annular lobe 11 is fan-shaped and arc-shaped. The first annular lobe 11 are sequentially connected to form an annular structure with a fan-shaped notch 15, i.e., a near-annular vacuum chamber 10. It is understood that the specific number of the first annular lobe 11 is not limited, as long as the fan-shaped first annular lobe 11 can be assembled into a circular shape. In this embodiment, the vacuum chamber has a total of 8 annular lobes, of which 7 are first annular lobe 11 and 1 is second annular lobe 40.

[0086] Further, in step S2, the components of the assembly platform 20 are hoisted from the fan-shaped notch 15 of the near-ring vacuum chamber 10. The assembly platform 20 is ring-shaped and is disposed within the near-ring vacuum chamber 10. Please refer to [link / reference]. Figure 2 In the cross-sectional direction of the annular petals, the petals are arranged in a "D" shape. Nine cladding layers 30 are fitted onto the inner wall of the petals, with the shape of each cladding layer 30 corresponding to the curved surface shape of a corresponding position on the petal. During assembly, the cladding layers 30 are installed from top to bottom in the cross-sectional direction of the petals, and are mounted along a circular trajectory on the inner wall of each first annular petal 11. (See reference...) Figure 2 In the process, each cladding layer 30 is marked as A1 to A9 in a clockwise direction. The installation sequence is A4, A5, A6, A3, A7, A2, A1, A8, A9. First, the cladding layer 30 at position A4 corresponding to each first annular lobe 11 is installed, and then the cladding layer 30 at position A5 corresponding to each first annular lobe 11 is installed, and so on.

[0087] Furthermore, in step S2, the assembly platform 20 has a detachable layered structure, so that the height of the assembly platform 20 changes accordingly as the installation height of the cladding 30 decreases. Understandably, the transport fixture 21 is a multi-degree-of-freedom movable robotic arm. The specific structure of the transport fixture 21 is not limited here, as long as it can transport the components of the cladding 30 and assist personnel in adjusting the installation position of the components of the cladding 30. Multiple transport fixtures 21 can be provided to ensure simultaneous synchronous installation of the cladding 30 at multiple locations, thereby improving assembly efficiency. In this embodiment, the distance between the assembly platform 20 and the top of the near-ring vacuum chamber 10 is 2 to 3 meters, and the distance between the assembly platform 20 and the side wall of the near-ring vacuum chamber 10 is 8 to 12 centimeters; the dimensions of the assembly platform 20 here refer to the distance from the highest layer to the inner wall of the near-ring vacuum chamber 10.

[0088] Further, step S3 includes:

[0089] S31: Install a shielding block pipeline on the inner wall of the first annular lobe 11;

[0090] S32: Install the shielding block 31 on the inner wall of the first annular petal 11, and connect the shielding block pipeline to the shielding block 31;

[0091] S33: Install the first wall pipe on the shielding block 31;

[0092] S34: Install the first wall 32 on the shielding block 31, and connect the first wall pipeline to the first wall 32.

[0093] Furthermore, in step S31, the shielding block pipeline is relatively lightweight and can be directly transported to the construction personnel on the assembly platform 20 by hoisting, or it can be hoisted onto the transport fixture 21 and transported to the designated installation position by the transport fixture 21. According to the assembly and welding requirements of the pipeline, the construction personnel weld and fix the shielding block pipeline sequentially as the cladding 30 is assembled. Finally, the shielding block pipeline is led out of the vacuum chamber from the upper and lower neck tubes of the vacuum chamber and connected to the refrigeration system.

[0094] Further, step S32 includes:

[0095] S321: Connect the shielding block 31 to the support fixture;

[0096] S322: Hoist the shielding block 31 and the support fixture together onto the transport fixture 21, and connect the support fixture to the transport fixture 21;

[0097] S323: The transport tool 21 moves on the assembly platform 20 to move the shielding block 31 to the corresponding installation position;

[0098] S324: Fix the shielding block 31 to the inner wall of the first annular petal 11, and connect the shielding block pipeline to the coolant inlet and outlet joints of the shielding block 31;

[0099] S325: Remove the aforementioned support fixture.

[0100] The cladding 30 includes a shielding block 31 and a first wall 32. The first wall 32 is located on the side of the shielding block 31 near the interior of the vacuum chamber, and the shielding block 31 is fixed to the inner wall of the vacuum chamber. Because the shielding block 31 is relatively heavy, a transport fixture 21 is needed to assist the construction personnel in adjusting the installation position of the shielding block 31 before the personnel fix it to the inner wall of the vacuum chamber. Since the shielding block 31 has different shapes at different locations, the support fixture needs to be designed according to the shape of the shielding block 31 at different locations. The support fixture is used to connect the shielding block 31 to the transport fixture 21.

[0101] Further, step S33 includes:

[0102] S331: Adjust the first wall pipe to a suitable state using a pipe bending tool;

[0103] S332: Fix the first wall pipe to the shielding block 31.

[0104] The shielding block 31 contains internal piping, with a coolant inlet connector and a coolant outlet connector at each end. These two connectors are collectively referred to as coolant inlet and outlet connectors. The coolant inlet and outlet connectors are located on the outer surface of the shielding block 31. The coolant inlet and outlet connectors are connected to the piping of the shielding block, which is fixed to the inner wall of the vacuum chamber.

[0105] Further, step S34 includes:

[0106] S341: Connect the heat sink of the first wall 32 to the support fixture;

[0107] S342: Hoist the heat sink and the support fixture together onto the transport fixture 21, and connect the support fixture to the transport fixture 21;

[0108] S343: The transport tool 21 moves on the assembly platform 20 to move the heat sink to the corresponding installation position of the shielding block 31;

[0109] S344: Connect and fix the heat sink to the shielding block 31, and connect the first wall pipe to the coolant inlet and outlet joints of the heat sink;

[0110] S345: Provide a tungsten tile for the first wall 32 and fix the tungsten tile to the heat sink;

[0111] S346: Remove the aforementioned support fixture.

[0112] The first wall 32 includes a heat sink and a tungsten tile. The heat sink is the main load-bearing component of the first wall 32, and the tungsten tile is located on the side of the first wall 32 closer to the interior of the vacuum chamber. The shape of the first wall 32 corresponds to that of the shielding block 31, and the support fixture used to install the shielding block 31 can continue to be used during the installation of the first wall 32. Cooling pipes are also embedded inside the heat sink, with coolant inlet and coolant outlet connectors at both ends, respectively. The coolant inlet and outlet connectors of the heat sink are connected to the pipes in the first wall.

[0113] Repeat the steps of S3 above to install each cladding layer 30. After the cladding layer 30 is assembled on the inner wall of each first annular lobe 11, proceed to step S4.

[0114] Further, in step S4, the assembly platform 20 is removed from the near-ring vacuum chamber 10; then, the second annular lobe 40 is installed at the fan-shaped notch 15 of the near-ring vacuum chamber 10, realizing the ring-closing operation of the first annular lobe 11 and the second annular lobe 40, forming a complete annular vacuum chamber. Understandably, the second annular lobe 40 has the same shape and structure as the first annular lobe 11, and the cladding 30 structure within the second annular lobe 40 can also be the same as the cladding 30 structure within the first annular lobe 11.

[0115] Further, in step S5, please refer to Figure 3 A transport track 50 is constructed at the window position in the second annular lobe 40 to transport the component into the vacuum chamber. An auxiliary tooling 51 is then assembled within the vacuum chamber to assist the construction personnel in adjusting the installation position of the component, which is then fixed by the construction personnel to assemble the cladding 30 onto the inner wall of the second annular lobe 40. Understandably, the auxiliary tooling 51 is a multi-degree-of-freedom robotic arm; its specific structure is not limited here, as long as it can adjust the installation position of the cladding 30.

[0116] Further, step S6 includes:

[0117] S61: Install a shielding block pipeline on the inner wall of the second annular lobe 40;

[0118] S62: Install the shielding block 31 on the inner wall of the second annular petal 40, and connect the shielding block pipeline to the shielding block 31;

[0119] S63: Install the first wall pipe on the shielding block 31;

[0120] S64: Install the first wall 32 on the shielding block 31, and connect the first wall pipeline to the first wall 32.

[0121] The construction steps for installing the cladding 30 on the inner wall of the second annular petal 40 are the same as those for installing the cladding 30 on the inner wall of the first annular petal 11, and will not be repeated here.

[0122] Further, step S61 includes:

[0123] S611: The shielding block pipeline is transported to the annular vacuum chamber via the transport track 50;

[0124] S612: Install the shielding block pipeline onto the inner wall of the second annular lobe 40.

[0125] Further, step S62 includes:

[0126] S621: Connect the shielding block 31 to the support fixture;

[0127] S622: The shielding block 31 and the supporting fixture are hoisted together onto the transport rail 50. The transport rail 50 transports the shielding block 31 and the supporting fixture to the auxiliary fixture 51. The supporting fixture and the auxiliary fixture 51 are then connected.

[0128] S623: The auxiliary tooling 51 moves the shielding block 31 to the corresponding installation position;

[0129] S624: Fix the shielding block 31 on the inner wall of the second annular petal 40, and connect the shielding block pipeline to the coolant inlet and outlet joints of the shielding block 31;

[0130] S625: Remove the supporting fixture.

[0131] Further, step S63 includes:

[0132] S631: The first wall pipe is transported to the annular vacuum chamber via the transport track 50;

[0133] S632: Adjust the first wall pipe to a suitable state using a pipe bending tool;

[0134] S633: Fix the first wall pipe to the shielding block 31.

[0135] Further, step S64 includes:

[0136] S641: The heat sink and the support fixture are hoisted together onto the transport track 50, the transport track 50 transports the heat sink and the support fixture to the auxiliary fixture 51, and the support fixture is connected to the auxiliary fixture 51;

[0137] S642: The auxiliary tooling 51 moves the heat sink to the corresponding installation position of the shielding block 31;

[0138] S643: Connect and fix the heat sink to the shielding block 31, and connect the first wall pipe to the coolant inlet and outlet joints of the heat sink;

[0139] S644: Provide a tungsten tile for the first wall 32, and fix the tungsten tile to the heat sink;

[0140] S645: Remove the aforementioned support fixture.

[0141] Repeat step S6 above to assemble each cladding layer 30 onto the inner wall of the second annular lobe 40. After all cladding layers 30 are installed, proceed to step S7 to remove the auxiliary tooling 51 and the transport track 50, thus completing the cladding layer 30 assembly task in the vacuum chamber.

[0142] In summary, the embodiments of the present invention provide a fusion reactor blanket assembly method, the beneficial effects of which are:

[0143] The assembly of the blanket 30 is divided into two stages: the near-ring vacuum chamber 10 stage and the annular vacuum chamber stage. In the near-ring vacuum chamber 10 stage, since the second annular lobe 40 is not yet connected, the assembly platform 20 and transport tooling 21 can be built within the near-ring vacuum chamber 10. Furthermore, components can be directly hoisted through the second annular lobe 40, eliminating the need to send components in through the windows on the annular lobe, thus greatly improving the assembly efficiency of the blanket 30. After installing the first part of the blanket 30, the second annular lobe 40 is then connected, and the blanket 30 is assembled onto the inner wall of the last second annular lobe 40. This results in high overall assembly efficiency, fewer restrictions on the structural design of the fusion reactor, and a wider range of applications.

[0144] The technical features of the above embodiments can be combined in any way.
