Description

Technical Field

[0001] This invention relates to the field of high-temperature gas-cooled reactor technology, and more particularly to a high-temperature gas-cooled reactor internal component module assembly plant. Background Technology

[0002] High-temperature gas-cooled reactors (HTGRs) are an advanced fourth-generation nuclear power reactor technology with advantages such as high safety, high efficiency, good economics, and wide applicability. HTGRs generate electricity through the conversion of nuclear energy into thermal energy, mechanical energy, and electrical energy, and can replace traditional fossil fuels, achieving coordinated economic and environmental development.

[0003] The in-core module of a high-temperature gas-cooled reactor (HTGR) is a collective term for all structural components within the pressure vessel of the HTGR, excluding fuel elements. A typical HTGR in-core module consists of four core shell sections, each 5 meters high. Adjacent core shell sections are connected by bolts and connecting plates. Metal and ceramic components are installed inside the core shells.

[0004] In existing technologies, the internal components (ICMs) of a high-temperature gas-cooled reactor (HTGR) are installed within the nuclear island. This requires sequentially hoisting the core shells into the pressure vessel of the nuclear island and assembling and securing each core shell. Additionally, metal and ceramic components need to be hoisted into the core shells for assembly. Since the ICMs are installed within the nuclear island, their installation is part of the overall reactor assembly process. Because the core shells must be installed section by section within the reactor, this significantly impacts the overall reactor timeline, resulting in a prolonged assembly period.

[0005] Therefore, how to avoid the problem of excessively long reactor mainline construction period caused by assembling the reactor core shell and metal and ceramic components in the reactor is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0046] The core of this invention is to provide a high-temperature gas-cooled reactor internal component module assembly plant to avoid the problem of excessively long reactor mainline construction period caused by assembling the reactor core shell and metal and ceramic components inside the reactor.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] like Figure 1 As shown, this embodiment of the invention discloses a high-temperature gas-cooled reactor internal component module assembly plant, including an assembly plant body 100. For example... Figure 2As shown, the interior of the assembly plant body 100 includes an assembly area 101. The assembly area 101 includes at least one assembly space for assembling the high-temperature gas-cooled reactor internal component module 110. That is, multiple assembly spaces can be set up in the assembly area 101 as needed. Each assembly space is enclosed by the walls of the assembly area, so that two adjacent assembly spaces are separated by the walls of the assembly area to form independent spaces.

[0049] The bottom of the assembly space is provided with equipment support components for supporting the high-temperature gas-cooled reactor in-core module 110. The arrangement of the equipment support components can be the same as that of the equipment support components in the reactor for supporting the high-temperature gas-cooled reactor in-core module 110, so that the equipment support components can be fully coupled to the interface at the bottom of the core shell of the high-temperature gas-cooled reactor in-core module 110.

[0050] Because the high-temperature gas-cooled reactor internal component module 110 has four core shell sections, each 5 meters high, and every two core shell sections are connected by bolts and connecting plates, the assembled high-temperature gas-cooled reactor internal component module 110 exceeds 20 meters in height. To facilitate the lifting of assembled or partially assembled high-temperature gas-cooled reactor internal component modules 110 out of the high-temperature gas-cooled reactor internal component module assembly plant, in this embodiment, an internal component lifting outlet is provided at the top of the assembly plant body 100. This internal component lifting outlet is located at a position corresponding to the assembly area 101. The internal component lifting outlet is used to lift the assembled high-temperature gas-cooled reactor internal component module from the assembly area 101 out of the assembly plant body 100 using lifting equipment. The internal component lifting outlet can be equipped with a detachable roof 200. After the high-temperature gas-cooled reactor internal component module 110 is assembled, the detachable roof 200 can be opened to lift the high-temperature gas-cooled reactor internal component module 110 out of the assembly plant using an external crane.

[0051] The high-temperature gas-cooled reactor internal component module assembly workshop provided by this invention includes an assembly area 101 inside the main assembly workshop 100. Several assembly spaces can be configured within the assembly area 101 as needed, each space used for assembling high-temperature gas-cooled reactor internal component modules 110. Each assembly space has a support assembly at its bottom for supporting the high-temperature gas-cooled reactor internal component module 110. During assembly within the assembly space, a section of the reactor core shell is first hoisted onto the support assembly, and then... Figure 5The diagram shows the three additional core shell sections being sequentially hoisted into the assembly space, with each pair of core shell sections connected and secured by bolts and connecting plates. This invention assembles the high-temperature gas-cooled reactor internals module 110 within the assembly plant, then lifts the assembled module from the internals lifting outlet using a hoisting device and installs it entirely into the reactor, eliminating the need to assemble the core shell and internals inside the pressure vessel. This invention prefabricates the high-temperature gas-cooled reactor internals module 110 in the assembly plant and then installs the prefabricated module into the reactor, thereby reducing the mainline construction period and improving reactor construction efficiency.

[0052] During the assembly of the high-temperature gas-cooled reactor internal component module 110, measurements are required using measuring equipment. The specific measuring equipment, methods, and data can be referenced from the process of assembling the high-temperature gas-cooled reactor internal component module 110 within the reactor. The assembly process of the high-temperature gas-cooled reactor internal component module 110 within the assembly plant is the same as that within the reactor. To ensure that one measuring device can simultaneously measure multiple high-temperature gas-cooled reactor internal component modules 110 in multiple assembly spaces, thus reducing the use of measuring equipment, in this embodiment, the assembly area 101 includes multiple assembly spaces arranged in an array. Adjacent assembly spaces are interconnected or separated by assembly area walls. To avoid affecting the assembly activities of other assembly spaces, adjacent assembly areas can be separated into enclosed spaces by assembly area walls. This invention, by arranging multiple assembly spaces in an array adjacent to each other, allows multiple assembly spaces to share a single measuring device.

[0053] Specifically, assembly area 101 includes, for example: Figure 2 The six assembly spaces shown are arranged in an array, either in a two-row, three-column configuration or in a three-row, two-column configuration. This allows each measuring device to measure the high-temperature gas-cooled reactor internal component modules 110 in at least four assembly spaces, meaning that at least four adjacent assembly spaces can share one measuring device.

[0054] Because the high-temperature gas-cooled reactor internals module 110 has four core shell sections, each 5 meters high, and every two core shell sections are connected by bolts and connecting plates, the connection between each pair of core shell sections is designed to facilitate secure fixing. Figure 4As shown, in this embodiment, a core shell assembly platform 114 can be provided within the assembly space. The core shell assembly platform 114 is located at a first preset distance below the connection position of every two core shell sections of the high-temperature gas-cooled reactor internal component module 110. The first preset distance should be set according to the height of the operator, so that the operator can easily operate when standing on the core shell assembly platform 114 to connect and fix adjacent core shell sections with bolts and connecting plates. One of the core shell assembly platforms 114 can be located on the same plane as the ground, or a certain height difference can be set according to the actual situation.

[0055] The first preset distance can be set to 0.8 to 1.2m. Taking the first preset distance of 1m as an example, the core shell assembly platform 114 is set 1m below the connection part of the two core shell sections. According to the average height of Chinese people of 1.7m, when the operator stands on the core shell assembly platform 114 to operate, the operator can be about 0.7m above the connection part of the two core shell sections, which is a relatively convenient height for the operator to operate.

[0056] After the reactor core shell is assembled, the internal components (i.e., metal and ceramic components) need to be installed. To facilitate the installation of metal and ceramic components, in this embodiment, an internal component installation platform 113 is also provided within the assembly space. The internal component installation platform 113 is located at a second predetermined distance below the top of the reactor core shell. Operators stand on the internal component installation platform 113 to assist the hoisting equipment in hoisting the metal and ceramic components into the reactor core shell for installation.

[0057] The second preset distance can be set to 0.8 to 1.2m. Taking the second preset distance of 1m as an example, the internal component installation platform 113 is set 1m below the top of the reactor core shell. According to the average height of Chinese people of 1.7m, when the operator stands on the internal component installation platform 113 to operate, the operator can be about 0.7m above the top of the reactor core shell, which is a relatively convenient height for the operator to operate.

[0058] To shorten the hoisting distance of the high-temperature gas-cooled reactor internals module 110 and reduce the risk of tipping over, the assembly space for the high-temperature gas-cooled reactor internals module 110 adopts a semi-underground structure. That is, the assembly space includes above-ground space and underground space, with the equipment support components located at the bottom of the underground space.

[0059] like Figure 6 and Figure 7As shown, the equipment support assembly includes multiple equipment supports 116 evenly arranged in a circle. The equipment supports 116 support the high-temperature gas-cooled reactor in-core module 110. The equipment supports 116 are used for coupling with the bottom interface of the reactor core shell to achieve a stable fit with the core shell. The number of equipment supports 116 can be the same as the number of equipment supports used to support the high-temperature gas-cooled reactor in-core module 110 within the reactor, i.e., 15. These 15 equipment supports 116 are evenly arranged in a circle. Figure 6 With the horizontal axis of the first quadrant at 0°, the equipment supports 116 are arranged starting 180° clockwise, with 15 evenly distributed along a circle.

[0060] During the assembly of the reactor core shell, parameters such as the axial angle of the core shell need to be adjusted. Therefore, in this embodiment, the equipment support assembly also includes multiple adjustment supports 117 evenly arranged in a circle. The adjustment supports 117 are used to adjust the internal component modules 110 of the high-temperature gas-cooled reactor. The adjustment supports 117 are generally hydraulic devices such as jacks. By adjusting the extension length of the piston rod of the support 117, the position parameters of the reactor core shell are adjusted.

[0061] The number of adjustment supports 117 can be the same as the number of adjustment supports used to adjust the in-core components module 110 of the high-temperature gas-cooled reactor, that is, three. The three adjustment supports 117 are evenly arranged in a circle. Figure 6 With the horizontal axis of the first quadrant at 0°, the adjustment supports 117 are arranged starting at 44° clockwise, with three evenly distributed along a circle. The equipment supports 116 and the adjustment supports 117 are arranged on the same circumference so that the equipment supports 116 and the adjustment supports 117 can simultaneously support the high-temperature gas-cooled reactor internals module 110.

[0062] like Figure 5 and Figure 7 As shown, to further facilitate the adjustment of the high-temperature gas-cooled reactor internal component module 110, in a specific embodiment of the present invention, an operating pit 115 is provided at the bottom of the underground space. The operating pit 115 is used by operators to adjust the high-temperature gas-cooled reactor internal component module 110. The operating pit 115 is located within the area enclosed by the equipment support components. The depth of the operating pit 115 should be set according to the height of a person so that the operator can easily observe the adjustment structure of the adjustment support 117 on the high-temperature gas-cooled reactor internal component module 110 and operate the adjustment support 117 from within the operating pit 115.

[0063] Metal and ceramic components need to be transported to assembly area 101 and hoisted from the ground of the assembly space onto the top core shell, and then hoisted into the core shell. Because the assembly space is equipped with a core shell assembly platform 114, the platform may or may not completely enclose the cross-section of the assembly space. When the platform completely encloses the cross-section, it will prevent the metal and ceramic components from being hoisted from the ground of the assembly space onto the top core shell.

[0064] Based on this, in a specific embodiment of the present invention, as follows: Figure 9 As shown, the core shell assembly platform 114 and the internal component installation platform 113, located in the ground space and above the ground, are provided with lifting holes 120. The lifting holes 120 are used to lift the metal and ceramic components of the high-temperature gas-cooled reactor internal component module 110. In this embodiment, by opening the lifting holes 120 on the platforms above the ground (partial core shell assembly platform 114 and internal component installation platform 113), the metal and ceramic components can pass through the lifting holes 120, facilitating lifting.

[0065] like Figure 8 As shown, in a specific embodiment of the present invention, the ground surface of the above-ground space and the middle part of the high-temperature gas-cooled reactor internal component module 110 are located on the same plane, which can reduce the transportation distance of metal and ceramic components. That is, only half the distance needs to be hoisted to the top of the reactor core shell. Moreover, the center of gravity of the high-temperature gas-cooled reactor internal component module 110 is located in its middle position. Therefore, the high-temperature gas-cooled reactor internal component module 110 can be supported by no less than one set of lateral support devices 119. The lateral support devices 119 are located in the underground space and close to the center of gravity of the high-temperature gas-cooled reactor internal component module 110. The center of gravity of the high-temperature gas-cooled reactor internal component module 110 is located in its middle position. The four sets of lateral support devices 119 are set near the middle of the high-temperature gas-cooled reactor internal component module 110, that is, in the underground space. The underground space is a reinforced concrete structure, which is more conducive to the setting of the lateral support devices 119.

[0066] like Figure 10 As shown, the high-temperature gas-cooled reactor internals module 110 requires specific temperature, humidity, and dust control conditions during its assembly outside the nuclear island. Therefore, this embodiment includes dehumidification and heating equipment 118 on the core shell assembly platform 114 and the internals module installation platform 113. This equipment heats and dehumidifies the surrounding environment to meet the environmental requirements during the assembly of the high-temperature gas-cooled reactor internals module 110.

[0067] To facilitate movement of operators between platforms, in this embodiment, staircases 121 are provided between two adjacent core shell assembly platforms 114, as well as between the top core shell assembly platform 114 and the internal component installation platform 113. The staircases 121 facilitate movement of operators between different platforms. Of course, elevators can also be used to connect the platforms.

[0068] like Figure 3 As shown, since the high-temperature gas-cooled reactor internal component modules 110 in each assembly space are not hoisted out of the assembly plant at the same time, in order to avoid affecting the assembly activities of other assembly spaces while hoisting the high-temperature gas-cooled reactor internal component modules 110, a cover plate 112 can be installed at the top of the assembly space to cover the top opening of the assembly space. When each high-temperature gas-cooled reactor internal component module 110 is hoisted, the cover plate 112 of its assembly space can be opened individually, while the cover plates 112 of other assembly spaces that are currently being assembled can be kept closed to avoid affecting the assembly activities of that assembly space.

[0069] like Figure 3 As shown, since some components need to be hoisted inside the assembly plant, in this embodiment, a crane 111 can be installed in the upper space of the assembly plant body 100 to meet the hoisting requirements of each component of the high-temperature gas-cooled reactor internal component module 110.

[0070] like Figure 3 As shown, depending on functional requirements, the interior of the assembly plant body 100 may also include a ring corridor 102. The ring corridor 102 is arranged around the assembly area 101 and is used for the transportation of the high-temperature gas-cooled reactor internal component modules 110 and for the passage of operators to and from the assembly area 101. Each assembly space in the assembly area 101 has an independent door, and operators can enter each assembly space in the assembly area 101 along the ring corridor 102.

[0071] Since the circular corridor 102 surrounds the assembly area 101, it is relatively long. To facilitate operators' access from outside the assembly plant 100 to various locations within the circular corridor 102, enabling them to quickly reach their destination, multiple doors connecting to the outside of the assembly plant 100 can be installed in different locations within the circular corridor 102.

[0072] The interior of the assembly plant body 100 may also include a cleaning and storage area 103, which may be located on one side of the circular corridor 102. The cleaning and storage area 103 has a door connecting to the circular corridor 102, allowing operators to access the cleaning and storage area 103 via the circular corridor 102. The cleaning and storage area 103 is used to clean the core shell of the high-temperature gas-cooled reactor internal component module 110 and to store the components of the high-temperature gas-cooled reactor internal component module 110. In other words, in addition to cleaning the core shell, the cleaning and storage area 103 can also serve as a storage warehouse for the components of the high-temperature gas-cooled reactor internal component module 110.

[0073] The assembly plant body 100 may also include other functional areas, which may include at least one of the following: a small parts degreasing area 104, an air compressor room 105, an electrical distribution room 106, a tool room 107, a personnel preparation area 108, and an office area 109. The small parts degreasing area 104 has a door connecting to the outside of the assembly plant body 100. The air compressor room 105, electrical distribution room 106, tool room 107, personnel preparation area 108, and office area 109 each have doors connecting to the circular corridor 102 and the outside of the assembly plant body 100, respectively. The personnel preparation area 108 and office area 109 are also connected by doors. The small parts degreasing area 104 is located on one side of the cleaning and storage area 103, and the small parts degreasing area 104, air compressor room 105, electrical distribution room 106, tool room 107, personnel preparation area 108, and office area 109 can be arranged sequentially.
