Technical Field

[0001] This application relates to the field of nuclear power plant monitoring technology, and in particular to a method, device, electronic equipment and storage medium for monitoring deformation of nuclear power plant containment. Background Technology

[0002] The containment vessel of a nuclear power plant is a prestressed concrete structure with protective and supporting functions. It can ensure that no radioactive elements will leak in the event of a large-scale reactor leak, and at the same time, it can resist external damage. It is the most important building structure of a nuclear power plant.

[0003] In order to monitor the changes of the nuclear power plant containment vessel under various complex internal and external loads in real time over a long period of time, and to determine the performance status of the containment vessel, a series of stress and deformation monitoring devices need to be installed. Among them, the deformation monitoring of the containment vessel cylinder is an important component, which can be used to assess the mechanical performance status of the containment vessel in real time, evaluate the safety attributes of the containment vessel, and provide important basis for the operation and maintenance of the nuclear power plant containment vessel.

[0004] Therefore, how to monitor and acquire the spatial deformation data of the containment vessel in real time has become an urgent technical problem to be solved. Summary of the Invention

[0005] The main objective of this application is to provide a method, device, electronic device, and storage medium for monitoring the deformation of a nuclear power plant containment structure, with the aim of real-time monitoring and acquisition of spatial deformation data of the containment structure.

[0006] To achieve the above objectives, a first aspect of this application provides a nuclear power plant containment deformation monitoring device, the device comprising:

[0031] In some embodiments, the cylinder deformation sensor further includes a mechanical sensor connected to the cylinder deformation monitoring body to monitor the displacement of the cylinder deformation monitoring body and obtain the displacement change of the monitoring point.

[0032] To achieve the above objectives, a second aspect of this application provides a method for monitoring the deformation of a nuclear power plant containment, applied to the nuclear power plant containment deformation monitoring device described in the first aspect above. The method includes:

[0033] The ground deformation sensor of the ground monitoring sub-module receives the displacement change of the top fixed point of the target containment body transmitted via a vertical wire, and obtains the displacement change of the top fixed point relative to the vertex of the ground deformation monitoring body.

[0049] The nuclear power plant containment deformation monitoring method, apparatus, electronic equipment, and storage medium proposed in this application receive displacement changes transmitted via a plumb line from a fixed top point of the target containment using a ground deformation sensor in a ground monitoring submodule. This yields the displacement change of the top fixed point relative to the vertex of the ground deformation monitoring body. Then, for each deformation monitoring location, the cylinder deformation sensor in the cylinder monitoring submodule monitors the displacement of the cylinder deformation monitoring body, obtaining the displacement change of the monitoring point relative to the fixed top point. Next, relative deformation analysis is performed based on the vertex displacement change and the corresponding monitoring point displacement change to obtain the target monitoring point deformation for each deformation monitoring location. Finally, a comprehensive deformation analysis is performed based on the deformation of each target monitoring point to obtain the target deformation information of the target containment. Therefore, this application uses a vertical conductor to transmit the displacement change of the top fixed point of the target containment, thereby obtaining the displacement change of the vertex and thus acquiring the spatial deformation data of the entire target containment. Then, by monitoring the displacement of the cylinder deformation monitoring body at each deformation monitoring position, the displacement change of the monitoring point relative to the top fixed point is obtained, thereby acquiring the relative deformation data of the target containment at each deformation monitoring position. Finally, by combining the displacement change of the vertex and the displacement change of the monitoring point, relative deformation analysis is performed to obtain the absolute spatial deformation data of the target containment at each deformation monitoring position.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0061] This application provides a method, apparatus, electronic device, and storage medium for monitoring the deformation of a nuclear power plant containment structure, with the aim of real-time monitoring and acquisition of spatial deformation data of the containment cylinder.

[0062] The nuclear power plant containment deformation monitoring method, device, electronic equipment, and storage medium provided in this application are specifically described through the following embodiments. First, the nuclear power plant containment deformation monitoring device in this application embodiment is described.

[0063] Figure 1 This is a side view of the nuclear power plant containment deformation monitoring device provided in this application embodiment, where the target containment is 100. Figure 1 The device may include, but is not limited to:

[0064] A plumb line 101 is provided, with one end fixed at the top fixed point 102 of the target containment 100 and the other end connected to a plumb anchor 103. The plumb anchor 103 acts on the plumb line to make it perpendicular to the ground. The plumb line includes multiple deformation monitoring positions 104 for monitoring spatial deformation data corresponding to the side surface of the target containment 100. The number of deformation monitoring positions 104 can be reasonably set according to the height of the target containment 100.

[0065] The deformation monitoring module 105 includes monitoring sub-modules corresponding to each deformation monitoring location 104. The deformation monitoring module 105 is used to monitor the deformation of the target containment vessel 100. The monitoring sub-modules include a ground monitoring sub-module 106 and multiple vessel monitoring sub-modules 107. The number of deformation monitoring locations 104 is equal to the number of vessel monitoring sub-modules 107 plus the number of ground monitoring sub-modules 106.

[0066] The cylinder body monitoring sub-module 107 includes a corresponding cylinder body support 108, a cylinder body deformation sensor 109, and a cylinder body deformation monitoring body 110. For each cylinder body monitoring sub-module 107:

[0067] The cylinder support 108 is mounted on the side surface of the target containment 100 via the support fixing part 111.

[0068] The cylinder deformation monitoring body 110 is fixed on the vertical guide wire 101 and is used to receive the displacement change transmitted from the top fixed point 102 via the vertical guide wire 101 at the corresponding deformation monitoring position 104.

[0069] The cylinder deformation sensor 109 is fixed to the cylinder support 108 and is used to monitor the displacement of the cylinder deformation monitoring body 110 to obtain the displacement change of the monitoring point.

[0070] The ground monitoring sub-module 106 includes a corresponding ground support 112, a ground deformation sensor 113, and a ground deformation monitoring body 114. Regarding the ground monitoring sub-module 106:

[0071] The ground support 112 is located on the ground directly below the top fixing point 102;

[0072] The ground deformation monitoring body 114 is fixed at the intersection of the vertical conductor 101 and the ground, and is used to receive the displacement change transmitted from the top fixed point 102 via the vertical conductor 101 on the ground.

[0073] Ground deformation sensor 113 is fixed to ground support 112 and is used to monitor the displacement of top fixed point 102 to obtain the change in vertex displacement.

[0074] Figure 2 This is a top view schematic diagram of the cylinder monitoring sub-module provided in the embodiments of this application. Figure 3This is a side view schematic diagram of the cylinder body monitoring sub-module provided in an embodiment of this application. In some embodiments, the cylinder body deformation sensor 109 includes a radial deformation sensor 201, a tangential deformation sensor 202, and a vertical deformation sensor 203. The displacement change of the monitoring point includes the radial displacement, tangential displacement, and vertical displacement of the monitoring point. The cylinder body deformation sensor 109 is fixed to the cylinder body support 108 and is used to monitor the displacement of the cylinder body deformation monitoring body to obtain the displacement change of the monitoring point, including:

[0075] The radial deformation sensor 201 is used to acquire the displacement of the cylinder deformation monitoring body 110 relative to the target containment 100 corresponding to the deformation monitoring position 104 in the radial direction, and to obtain the radial displacement of the monitoring point.

[0076] The cylinder tangential deformation sensor 202 is used to obtain the displacement of the cylinder deformation monitoring body 110 relative to the target containment 100 corresponding to the deformation monitoring position 104 in the circumferential tangential direction, and to obtain the tangential displacement of the monitoring point.

[0077] The cylinder vertical deformation sensor 203 is used to obtain the displacement of the cylinder deformation monitoring body 110 relative to the target containment 100 corresponding to the deformation monitoring position 104 in the height direction, and obtain the vertical displacement of the monitoring point.

[0078] In some embodiments, the cylinder support 108 includes a first cylinder support 301, a second cylinder support 302, and a third cylinder support 303. The first cylinder support 301 is connected to the support fixing part 111 and is arranged along the radial direction of the target containment 100 for mounting the cylinder tangential deformation sensor 202. The second cylinder support 302 is perpendicular to the first cylinder support 301 and parallel to the circumferential tangential direction relative to the target containment 100, for mounting the cylinder radial deformation sensor 201. The third cylinder support 303 is connected to the first cylinder support 301 and extends to the same vertical line as the cylinder deformation monitoring body 110, so that the mounted cylinder vertical deformation sensor 203 can monitor the displacement of the cylinder deformation monitoring body 110 relative to the target containment 100 in the height direction.

[0079] It should be noted that, Figure 2 and Figure 3 For structural illustration only. Figure 2The third support 303 of the cylinder body, as shown in the diagram, does not coincide with the first support 301 of the cylinder body and the cylinder deformation monitoring body 110. This is only to indicate that the third support 303 of the cylinder body is not on the same horizontal plane as the first support 301 of the cylinder body and the cylinder deformation monitoring body 110. This allows the vertical deformation sensor 203 of the cylinder body installed on the third support 303 of the cylinder body to detect the displacement of the cylinder deformation monitoring body 110 relative to the target containment 100 in the height direction. This can be referred to in this regard. Figure 3 The corresponding display is obtained. The structure of the first support 301, the second support 302, and the third support 303 of the cylinder body is not limited to that shown in the figure. The second support 302 can also be set in the first support 301 at the position between the cylinder deformation monitoring body 110 and the side surface of the target containment 100. The third support 303 can be set at any position of the first support 301, and the shape of the third support 303 itself is not limited, as long as it can enable the installed vertical deformation sensor 203 of the cylinder body to detect the displacement of the cylinder deformation monitoring body 110 relative to the target containment 100 in the height direction.

[0080] and Figure 2 and Figure 3 The size of each part displayed in the image is not strictly limited; those skilled in the art can set the specific size of each part according to actual needs.

[0081] In some embodiments, the ground deformation sensor includes a ground radial deformation sensor, a ground tangential deformation sensor, and a ground vertical deformation sensor. The vertex displacement change includes the vertex radial displacement, the vertex tangential displacement, and the vertex vertical displacement. Displacement monitoring of the top fixed point yields the vertex displacement change, including:

[0082] The ground radial deformation sensor is used to obtain the displacement of the top fixed point relative to the ground deformation monitoring body in the radial direction of the target containment, thus obtaining the radial displacement of the top.

[0083] The ground tangential deformation sensor is used to obtain the displacement of the top fixed point relative to the ground deformation monitoring body in the circumferential tangential direction of the target containment, and to obtain the vertex tangential displacement.

[0084] The ground vertical deformation sensor is used to obtain the displacement of the top fixed point relative to the ground deformation monitoring body in the height direction of the target containment, thus obtaining the vertical displacement of the top.

[0085] In some embodiments, the plumb anchor is embedded in a damping material beneath the ground to keep the plumb line straight, wherein the plumb line is inelastic. To ensure the plumb line remains straight and effectively transmits deformation information from the target containment top anchor point, the plumb anchor is embedded in a damping material beneath the ground. This damping material typically refers to a material capable of absorbing and dissipating energy, such as rubber, asphalt, or water, or other specialized damping materials. This stabilizes the plumb anchor and reduces the impact of external dynamic loads such as vibrations or wind on the monitoring system.

[0086] In addition, placing plumb anchors within damping material beneath the ground provides a stable anchor point for the plumb line, ensuring it remains taut under various environmental conditions. This helps reduce plumb line deformation caused by uneven ground settlement, temperature changes, or other external factors, thereby ensuring the stability and reliability of monitoring data.

[0087] In some embodiments, a cantilever beam is provided at the top of the target containment vessel, with a top fixing point located at the other end of the cantilever beam. This ensures a predetermined safety assessment distance between the plumb line and the cylinder deformation monitoring unit fixed to the plumb line and the side surface of the target containment vessel. Through the cantilever beam and the plumb anchor on the ground, the plumb line forms a quadrilateral relative to the side surface of the target containment vessel. Thus, when the target containment vessel deforms, causing a change in the position of the top fixing point, the displacement change of the top fixing point is transmitted through the plumb line to the ground monitoring sub-module. Furthermore, the predetermined safety assessment distance prevents the side surface of the target containment vessel from deforming and contacting the plumb line, thus avoiding interference with the displacement change transmitted from the top fixing point to the ground monitoring sub-module.

[0088] In some embodiments, the cylinder deformation sensor includes an optical displacement sensor, and the cylinder deformation monitoring body includes a monitoring hexahedron for the optical displacement sensor to acquire the displacement change of the monitoring points on the monitoring hexahedron. The light beam emitted by the optical displacement sensor illuminates a specific face of the monitoring hexahedron. When the target containment vessel deforms, the relative position of the cylinder support and the monitoring hexahedron also changes, causing a corresponding displacement of the reflected light beam. Detection by the optical displacement sensor allows for accurate acquisition of the displacement change of the cylinder deformation monitoring body relative to the cylinder support. When the cylinder deformation sensor includes a radial deformation sensor, a tangential deformation sensor, and a vertical deformation sensor, the cylinder deformation monitoring body is a monitoring hexahedron. Each optical displacement sensor can illuminate three different specific faces of the monitoring hexahedron, allowing for better acquisition of the displacement change of the cylinder deformation monitoring body relative to the cylinder support in three different directions.

[0089] In practical applications, the size of the cylinder deformation monitoring body needs to be such that when the target containment deforms and causes the cylinder support to move, the cylinder tangential deformation sensor installed on the first cylinder support, the cylinder radial deformation sensor installed on the second cylinder support, and the cylinder vertical deformation sensor installed on the third cylinder support can stably monitor the displacement change of the cylinder deformation monitoring body, so that the cylinder tangential deformation sensor, cylinder radial deformation sensor, and cylinder vertical deformation sensor will not lose their monitoring of the cylinder deformation monitoring body.

[0090] In some embodiments, the cylinder deformation sensor also includes a mechanical sensor connected to the cylinder deformation monitoring body to monitor the displacement of the monitoring body and obtain the displacement change at the monitoring point. In this case, the cylinder deformation sensor is connected to the cylinder deformation monitoring body through a force transmission medium, and the displacement of the monitoring body is indirectly obtained through the force detected by the cylinder deformation sensor.

[0091] In some embodiments, the target containment includes multiple segmented monitoring areas, each segmented monitoring area is equipped with a corresponding plumb line and deformation monitoring module. When the ground monitoring sub-module of the plumb line and deformation monitoring module cannot contact the ground, the accessible horizontal plane is used as the setting area for the plumb line and ground monitoring sub-module.

[0092] Under normal circumstances, one end of a plumb line is fixed to the top of the target containment vessel, while the other end is in contact with the ground via a ground monitoring sub-module to monitor displacement changes of the top fixed point relative to the ground. However, in some cases, due to environmental constraints or the specific structure of the containment vessel, the ground monitoring sub-modules in some segmented monitoring areas may not be in direct contact with the ground. In such cases, an accessible horizontal surface can be used as the installation area for the plumb line and the ground monitoring sub-module. Fixing the ground end of the plumb line to a stable horizontal surface simulates ground contact, allowing for monitoring of displacement changes of the top fixed point relative to this horizontal surface. This horizontal surface can be a platform near the target containment vessel, a special support structure, or any other stable and accessible horizontal surface. Using this alternative, the ground monitoring sub-module of the deformation monitoring module can be fixed to this horizontal surface to continue monitoring the spatial deformation data of the target containment vessel, collecting displacement changes transmitted from the top fixed point via the plumb line. This improves the adaptability of the nuclear power plant containment deformation monitoring device, ensuring continuous deformation monitoring of the target containment vessel even under complex field conditions.

[0093] Furthermore, by segmenting the target containment into monitoring zones, more precise monitoring can be conducted on areas of particular concern, improving the targeting of monitoring. These monitoring zones can be divided based on external load conditions, such as temperature changes, pressure changes, or external impacts.

[0094] Please see Figure 4 , Figure 4 This is a schematic flowchart of a nuclear power plant containment deformation monitoring method provided in an embodiment of this application. Figure 4 The method may include, but is not limited to, steps S401 to S404:

[0095] Step S401: The ground deformation sensor of the ground monitoring sub-module receives the displacement change of the top fixed point of the target containment via a vertical wire on the ground, and obtains the displacement change of the top fixed point relative to the vertex of the ground deformation monitoring body.

[0096] Step S402: For each deformation monitoring position, the displacement of the cylinder deformation monitoring body is monitored by the cylinder deformation sensor of the cylinder monitoring sub-module to obtain the displacement change of the monitoring point relative to the top fixed point for each deformation monitoring position.

[0097] Step S403: Based on the change in vertex displacement and the corresponding change in the displacement of monitoring point, perform relative deformation analysis to obtain the deformation of the target monitoring point corresponding to each deformation monitoring position.

[0098] Step S404: Perform comprehensive deformation analysis based on the deformation of each target monitoring point to obtain the target deformation information of the target containment.

[0099] In step S401 of some embodiments, the ground deformation sensor of the ground monitoring submodule receives the displacement change of the top fixed point of the target containment vessel transmitted via a plumb line, thus obtaining the displacement change of the top fixed point relative to the vertex of the ground deformation monitoring body. Since the ground monitoring submodule is located on the ground, its position is not affected by deformation of the target containment vessel; therefore, the ground monitoring submodule functions as a reference point. When the target containment vessel deforms, the deformation will affect the top position of the target containment vessel to some extent. Therefore, the displacement change relative to the ground deformation monitoring body, transmitted via a plumb line from the top fixed point of the target containment vessel, can be obtained when the target containment vessel deforms. This displacement change can then be detected by the ground deformation sensor of the ground monitoring submodule to obtain the vertex displacement change.

[0100] In step S402 of some embodiments, for each deformation monitoring position, the displacement of the cylinder deformation monitoring body is monitored by the cylinder deformation sensor of the cylinder monitoring sub-module to obtain the displacement change of the monitoring point relative to the top fixed point for each deformation monitoring position. In some cases, if deformation occurs at individual locations on the side surface of the target containment vessel, such as bulging and collapse, but the deformation does not affect the top fixed point of the target containment vessel, i.e., deformation occurs relative to the top fixed point of the target containment vessel, it cannot be detected by the ground monitoring sub-module.

[0101] At this point, multiple deformation monitoring positions are set along a vertical guideline corresponding to the side surface of the target containment vessel. The displacement of the deformation monitoring body is monitored by the deformation sensor of the vessel monitoring sub-module. If the side surface of the target containment vessel deforms, such as bulging or collapsing, it will affect the position of the vessel support in the vessel monitoring sub-module. The vessel support will then undergo a displacement change relative to the deformation monitoring body, which the deformation sensor of the vessel monitoring sub-module can detect. Since the deformation monitoring body is fixed to the vertical guideline, with one end of the guideline fixed at the top of the target containment vessel and the other end fixed to a vertical anchor on the ground, the vertical guideline transmits the displacement change of the top fixed point of the target containment vessel. The displacement change detected by the deformation sensor of the vessel monitoring sub-module represents the relative deformation of the side surface of the target containment vessel relative to the top fixed point at each deformation monitoring position.

[0102] In step S403 of some embodiments, relative deformation analysis is performed based on the change in vertex displacement and the corresponding change in displacement of monitoring points to obtain the target monitoring point deformation corresponding to each deformation monitoring position. By using the change in vertex displacement, i.e., the absolute displacement change of the top fixed point of the target containment relative to the ground deformation monitoring body, and the change in monitoring point displacement corresponding to each deformation monitoring position, i.e., the relative displacement change between the side surface position of the target containment corresponding to each deformation monitoring position and the top fixed point of the target containment, relative deformation analysis can be performed to obtain the absolute displacement change occurring on the side surface of the target containment corresponding to each deformation monitoring position, i.e., the target monitoring point deformation.

[0103] In step S404 of some embodiments, a comprehensive deformation analysis is performed using the obtained deformation variables of each target monitoring point. The deformation variables of all target monitoring points corresponding to the outer surface positions of the target containment are summarized and analyzed to obtain target deformation information corresponding to the side surface of the target containment. This target deformation information is used to represent the spatial deformation information of the side surface of the target containment monitored by the nuclear power plant containment deformation monitoring device.

[0104] In this embodiment, the ground deformation sensor of the ground monitoring submodule receives the displacement change of the top fixed point of the target containment vessel transmitted via a plumb line, obtaining the displacement change of the top fixed point relative to the vertex of the ground deformation monitoring body. Then, for each deformation monitoring location, the cylinder deformation sensor of the cylinder monitoring submodule monitors the displacement of the cylinder deformation monitoring body, obtaining the displacement change of the monitoring point relative to the top fixed point for each deformation monitoring location. Next, relative deformation analysis is performed based on the vertex displacement change and the corresponding monitoring point displacement change to obtain the target monitoring point deformation for each deformation monitoring location. Finally, a comprehensive deformation analysis is performed based on the deformation of each target monitoring point to obtain the target deformation information of the target containment vessel. Therefore, this application uses a vertical conductor to transmit the displacement change of the top fixed point of the target containment, thereby obtaining the displacement change of the vertex and thus acquiring the spatial deformation data of the entire target containment. Then, by monitoring the displacement of the cylinder deformation monitoring body at each deformation monitoring position, the displacement change of the monitoring point relative to the top fixed point is obtained, thereby acquiring the relative deformation data of the target containment at each deformation monitoring position. Finally, by combining the displacement change of the vertex and the displacement change of the monitoring point, relative deformation analysis is performed to obtain the absolute spatial deformation data of the target containment at each deformation monitoring position.

[0105] Please see Figure 5 In some embodiments, the vertex displacement change includes the vertex radial displacement, vertex tangential displacement, and vertex vertical displacement; the monitoring point displacement change includes the monitoring point radial displacement, monitoring point tangential displacement, and monitoring point vertical displacement; step S403 may include, but is not limited to, steps S501 to S503.

[0106] Step S501: Perform relative deformation analysis based on the radial displacement of the vertex and the radial displacement of the monitoring point to obtain the radial deformation corresponding to the deformation monitoring position;

[0107] Step S502: Perform relative deformation analysis based on the tangential displacement of the vertex and the tangential displacement of the monitoring point to obtain the tangential deformation corresponding to the deformation monitoring position;

[0108] Step S503: Based on the vertical displacement of the vertex and the vertical displacement of the monitoring point, perform relative deformation analysis to obtain the vertical deformation corresponding to the deformation monitoring position.

[0109] In steps S501 to S503 of some embodiments, relative deformation analysis is performed based on the radial displacement of the top fixed point and the radial displacement of the monitoring points on the target containment side surface corresponding to each deformation monitoring position, to obtain the corresponding radial deformation, thus obtaining the expansion and collapse deformation of the target containment side surface corresponding to the deformation monitoring position. Similarly, relative deformation analysis is performed based on the tangential displacement of the top point and the tangential displacement of the monitoring points, to obtain the tangential deformation corresponding to the deformation monitoring position, thus obtaining the torsion and misalignment deformation of the target containment side surface corresponding to the deformation monitoring position. Similarly, relative deformation analysis is performed based on the vertical displacement of the top point and the vertical displacement of the monitoring points, to obtain the vertical deformation corresponding to the deformation monitoring position, thus obtaining the subsidence and convexity deformation of the target containment side surface corresponding to the deformation monitoring position.

[0110] Through steps S501 to S503, the deformation information of the side surface of the target containment at each deformation monitoring location in the radial, tangential, and vertical directions can be obtained, providing detailed spatial deformation information for the comprehensive deformation analysis of the target containment.

[0111] Please see Figure 6 In some embodiments, step S404 may include, but is not limited to, steps S601 to S602:

[0112] Step S601: Perform segmentation based on each deformation monitoring location to obtain the deformation monitoring area;

[0113] Step S602: Perform deformation source analysis based on each deformation monitoring area to obtain the target deformation source area.

[0114] In step S601 of some embodiments, the target containment is divided into multiple deformation monitoring regions, each containing a certain number of deformation monitoring locations. By performing feature analysis on the deformation of the deformation monitoring locations, it is possible to identify deformation monitoring regions exhibiting similar deformation characteristics, thereby classifying them into deformation monitoring regions with a common deformation pattern.

[0115] By segmenting the deformation monitoring locations, it becomes easier to conduct more focused and precise analysis on areas of particular interest. For example, because the environmental factors on the outer surface of the target containment vessel corresponding to some deformation monitoring locations differ from those at other locations—potentially due to factors such as temperature, pressure, and structure—special deformation analysis processing is required for the outer surface of the target containment vessel corresponding to these deformation monitoring locations. This can be achieved by using more precise deformation sensors or equipment adapted to environmental factors.

[0116] On the other hand, it is also possible that due to the limitations of the installation environment, the installation of the nuclear power plant containment deformation monitoring device may need to be carried out in sections, thus dividing each deformation monitoring location into multiple deformation monitoring areas.

[0117] In step S602 of some embodiments, deformation source analysis is performed based on each deformation monitoring area. By analyzing the spatial deformation data of each deformation monitoring area, such as comparing the magnitude, trend, and distribution characteristics of the deformation, the source causing the deformation can be inferred. For example, if the deformation of a certain deformation monitoring area is significantly greater than that of other deformation monitoring areas, or if the deformation trend is inconsistent with the surrounding deformation monitoring areas, this may indicate that a deformation source exists in that deformation monitoring area, and it is identified as a target deformation source area.

[0118] Furthermore, deformation source analysis can also involve assessing external load conditions, such as temperature changes, pressure changes, or external impacts, to determine whether these factors have a significant impact on the deformation of the target containment. For the target deformation source area, engineers can take targeted measures to address the deformation, such as strengthening the structure, adjusting load distribution, or carrying out repairs.

[0119] Through steps S601 and S602, deformation information about different regions of the target containment can be obtained. By dividing the deformation monitoring area and locating the deformation source, the target deformation source area can be identified, which helps to formulate effective maintenance strategies and preventive measures to ensure the stability and reliability of the nuclear power plant's containment structure during long-term operation. In-depth analysis of the deformation data in the deformation monitoring area can help identify and resolve potential structural problems in advance, thereby improving the overall safety of the nuclear power plant.

[0120] Please see Figure 7 In some embodiments, the nuclear power plant containment deformation monitoring device provided in this application is provided on different side surfaces of the target containment. After step S404, steps S701 to S702 may be included, but are not limited to:

[0121] Step S701: Obtain target deformation information for each orientation of the target containment vessel;

[0122] Step S702: Perform overall deformation analysis of the containment based on the first number of target deformation information to obtain the overall deformation information of the target containment;

[0123] In step S701 of some embodiments, the nuclear power plant containment is a complex three-dimensional structure, and its deformation may be different in different directions. Therefore, the nuclear power plant containment deformation monitoring device provided in this application can be set in different directions of the target containment to collect target deformation information in each direction.

[0124] In step S702 of some embodiments, the target deformation information from various orientations is summarized and compared to identify the overall deformation trend and pattern of the target containment. By comprehensively analyzing the target deformation information from different orientations, the overall deformation information of the containment can be obtained. Through overall deformation analysis, key indicators such as the maximum, minimum, and average values ​​of deformation, as well as the uniformity of deformation distribution, can be obtained for the target containment in various orientations. The deformation behavior of the target containment can also be simulated by performing finite element analysis on the collected target deformation information from various orientations, and the spatial deformation of the target containment can be obtained through digital modeling technology. Based on the obtained overall deformation information, it can also be used to simulate the response of the target containment under different load conditions, including internal pressure, temperature changes, and seismic action.

[0125] Through steps S701 to S702, the overall deformation information of the target containment can be obtained, and the spatial deformation data of the target containment in various directions can be obtained. This allows for a more accurate identification of potential problems and risks in the containment, enabling targeted measures to be taken to ensure the safe operation of the nuclear power plant.
