DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The embodiment of the present invention provides a modular construction and installation system for the internal components of a high-temperature gas-cooled reactor nuclear power plant, such as Figure 1 、 Figure 3 and Figure 6 As shown, it includes: a pre-assembly plant, a first crane 10 and a second crane 600;

[0036] The pre-assembled plant is used to be arranged outside the nuclear island plant, and a retractable roof 300 is provided on the top of the plant. Figure 2 As shown, the pre-assembly workshop is provided with an internal component module assembly area 02, which is aligned with the roof 300 in the vertical direction;

[0037] The first crane 10 is set in the pre-assembly workshop and can sequentially lift the multiple cylinders moved into the pre-assembly workshop into the internal component module assembly area 02 to assemble into the internal component cylinders (such as Figure 4 As shown), and multiple modular components moved into the pre-assembly workshop can be sequentially hoisted into the internal component cylinder to assemble into the internal component module 400 (as shown Figure 5 shown);

[0038] The second crane 600 is arranged outside the pre-assembly building and is used to lift the reactor internals module 400 out of the pre-assembly building and lift it into the reactor pressure vessel cylinder 500 installed in the reactor compartment 700 of the nuclear island building for installation (e.g. Figure 6 、 Figure 7 and Figure 8 shown).

[0039] It should be noted that if Figure 1 As shown, when the preassembled in-core component module 400 is ready to be lifted out of the preassembly plant, the roof 300 is in an open state, so as to serve as a passage for lifting the in-core component module 400 out of the preassembly plant. Of course, the roof 300 is in a closed state under normal circumstances to keep the preassembly plant closed. In addition, the in-core component module 400 is the core support structure, and the in-core component cylinder is the core shell cylinder. In addition, the first crane 10 is a small crane (80t crane) set in the preassembly plant, and is used to lift the cylinder and module components to assemble the in-core component module 400; the second crane 600 is a large crane set outside the preassembly plant, as shown in FIG. Figure 6 As shown, the large crane may be a large crawler crane, and is used to lift the reactor internals module 400 from the pre-assembly building and lift it into the installed reactor pressure vessel cylinder 500 for installation.

[0040] That is to say, in this solution, while the civil construction of the reactor compartment 700 is being carried out and the reactor pressure vessel cylinder 500 is being installed, the in-core components can be assembled into an in-core component module 400 by a first crane 10 in a pre-assembly building outside the nuclear island building. Then, after the installation of the reactor pressure vessel cylinder 500 is completed, the in-core component module 400 can be lifted out of the pre-assembly building by a second crane 600 and lifted into and installed in the reactor pressure vessel cylinder 500, thereby effectively shortening the main construction period of the high-temperature gas-cooled reactor, helping to save 5 months of the main construction period of the high-temperature gas-cooled reactor, and also helping to improve the economy of the high-temperature gas-cooled reactor.

[0041] In this solution, in order to better assemble the in-core component module in the in-core component module assembly area 02, as shown in FIG. Figure 2 and Figure 3 As shown, the internal component module assembly area 02 is provided with a plurality of assembly pits 20 and a plurality of assembly platforms 12;

[0042] A plurality of assembly platforms 12 are arranged in a one-to-one correspondence around a plurality of assembly pits 20. That is, the first crane 10 is used to first hoist the plurality of cylinders moved into the pre-assembly workshop into one assembly pit 20 in sequence to assemble into an internal component cylinder, and then hoist the plurality of module components moved into the pre-assembly workshop into the internal component cylinder in sequence to assemble into an internal component module 400; and in the internal component module assembly area 02, each assembly pit 20 is equipped with an assembly platform 12, such as Figure 3 As shown, the assembly platform 12 is a multi-layer structure from bottom to top, so as to facilitate the sequential assembly of multiple cylinders from bottom to top.

[0043] Furthermore, if Figure 2 As shown, multiple assembly pits 20 are arranged in two rows, with each row containing multiple, aligned pits 20. This design increases the assembly capacity of reactor internals modules, thereby further shortening the main construction period of the high-temperature gas-cooled reactor.

[0044] Specifically, if Figure 1 As shown, the pre-assembled factory building includes: a pre-assembled factory building above-ground part 200 and a pre-assembled factory building underground part 100;

[0045] The above-ground part 200 of the pre-assembly plant is arranged on the ground; the underground part 100 of the pre-assembly plant is arranged underground and is connected with the above-ground part 200 of the pre-assembly plant. Figure 3 As shown, the internal component module assembly area 02 is distributed at the bottom of the underground part 100 of the pre-assembly plant and extends upward to the above-ground part 200 of the pre-assembly plant; the roof 300 is distributed on the top of the above-ground part 200 of the pre-assembly plant; Figure 4 As shown, the first crane 10 is installed within the above-ground portion 200 of the preassembly plant and spans above the underground portion 100. In other words, this solution places the reactor internals module assembly area 02 underground, thereby lowering the assembly height of the preassembly plant and minimizing interference with the assembly of the reactor internals modules.

[0046] In this solution, a closable factory door is provided on the side of the above-ground part 200 of the preassembly plant, so that when the factory door is opened, a transfer vehicle can easily transfer multiple cylinders or multiple modular components to the preassembly plant.

[0047] Furthermore, in order to facilitate the arrangement of other functional areas or other supporting areas in the above-ground part 200 of the pre-assembly plant, such as Figure 1 As shown, the floor area of ​​the above-ground part 200 of the pre-assembly factory building is larger than the floor area of ​​the underground part 100 of the pre-assembly factory building.

[0048] Furthermore, if Figure 2 As shown, the above-ground portion 200 of the pre-assembly plant houses a parts storage and large component cleaning area 01, located between the plant entrance and the internal component module assembly area 02. This design facilitates the storage and cleaning of large components, such as multiple cylinders or modular components, after they are moved into the pre-assembly plant.

[0049] In order to further optimize the above technical solutions and enrich the supporting measures of pre-assembled workshops, such as Figure 2 As shown, the above-ground part 200 of the pre-assembly plant is provided with a small parts degreasing area 04, an air compressor room 05, a power distribution room 06, a tool room 07, a personnel preparation area 08 and / or an office area 09, and is located on one side of the reactor internal component module assembly area 02.

[0050] An embodiment of the present invention further provides a method for modularizing the construction and installation of internal components of a high-temperature gas-cooled reactor nuclear power plant, which uses the modularized construction and installation system for internal components of a high-temperature gas-cooled reactor nuclear power plant as described above for construction and installation, and includes the following steps:

[0051] S1. Use a transfer vehicle to move multiple cylinders and multiple modular components into the pre-assembly workshop; wherein, the transfer vehicle is used to move multiple cylinders and multiple modular components into the parts storage and large component cleaning area 01 for storage or cleaning; in addition, the first crane 10 is a beam crane and spans the parts storage and large component cleaning area 01 and the in-core component module assembly area 02;

[0052] S2, using the first crane 10 to first hoist multiple cylinders into the internal component module assembly area 02 in sequence and assemble them into the internal component cylinders (such as Figure 4 Then, multiple modular components are sequentially hoisted into the in-core component cylinder to assemble into an in-core component module 400 (as shown in FIG. Figure 5 shown);

[0053] S3, using the second crane 600 to lift the reactor internals module 400 out of the pre-assembly building and to lift it into the reactor pressure vessel cylinder 500 installed in the reactor compartment 700 of the nuclear island building for installation (e.g. Figure 6 and Figure 7 shown).

[0054] It should be noted that this solution uses a transfer vehicle to move multiple cylinders and multiple module components into the parts storage and large parts cleaning area 01 for storage or cleaning; in addition, if Figure 4 As shown, the first crane 10 is a beam crane, and spans the parts storage and large parts cleaning area 01 and the in-core component module assembly area 02, so that the first crane 10 can lift the cylinder or module component from the parts storage and large parts cleaning area 01 into the in-core component module assembly area 02 to assemble it into an in-core component module; Figure 4 As shown, in step S2, the four cylinders (fourth cylinder 16, third cylinder 15, second cylinder 14, and first cylinder 13) are sequentially hoisted into the internals module assembly area 02 using a first crane 10 for assembly into the internals cylinder. Of course, since this solution utilizes the aforementioned modular construction and installation system for high-temperature gas-cooled reactor nuclear power plants for construction and installation, it also has corresponding beneficial effects. For details, please refer to the previous description and will not be repeated here.

[0055] In this program, if Figure 5 As shown, in step S2, the plurality of modular components are sequentially hoisted into the internal component cylinder to be assembled into the internal component module 400, which includes:

[0056] Then, the module bottom component 17 , the module middle component 18 and the module top component 19 are sequentially hoisted into the in-core component cylinder to be assembled into the in-core component module 400 .

[0057] The present invention will be further described below with reference to specific embodiments:

[0058] The modular construction and installation method for in-core components adopted by the present invention is as follows: while the civil construction of the reactor compartment and the installation of the reactor pressure vessel cylinder are underway, the in-core components are assembled into a module in a pre-assembly building outside the nuclear island plant. After the installation of the reactor pressure vessel cylinder is completed, the in-core component module is hoisted into and installed within the reactor pressure vessel cylinder. At the same time, the present invention proposes a one-time installation method for the installation and adjustment of the in-core component module. The method mainly calculates the processing volume of the height adjustment pad through three-dimensional measurement means, completes the adjustment pad processing in advance, and while the in-core component module is in place, a self-designed guide device is installed to ensure that the in-core component module is precisely positioned at the installation position, thereby reducing its safety and quality risks during installation. The modular construction method for in-core components can save a total of 5 months of the main construction period of the high-temperature gas-cooled reactor.

[0064] (4) First complete the core shell assembly cylinder assembly in the assembly area;
