[0002] The containment vessel of a nuclear power plant is a prestressed concrete structure with protection and support functions. It can ensure that in the event of a large-scale leak in the reactor, there will be no leakage of radioactive elements. At the same time, it must be able to resist external invasion. It is the most important building structure facility in a nuclear power plant.

[0003] In order to monitor the changes of nuclear power plant containment under various complex internal and external loads in real time over a long period of time and to judge the performance status of the nuclear power plant containment, it is necessary to set up a series of force and deformation monitoring equipment.

[0070] The ground monitoring submodule 106 includes a corresponding ground bracket 112, a ground deformation sensor 113 and a ground deformation monitoring body 114. For the ground monitoring submodule 106:

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

[0072] The ground deformation monitoring body 114 is fixed at the intersection of the plumb line 101 and the ground, and is used to receive the displacement change amount of the top fixed point 102 transmitted via the plumb line 101 on the ground;

[0074] Figure 2 is a top view schematic diagram of the barrel monitoring submodule provided in an embodiment of the present application, Figure 31 is a side view schematic diagram of the barrel monitoring submodule provided in an embodiment of the present application. In some embodiments, the barrel deformation sensor 109 includes a barrel radial deformation sensor 201, a barrel tangential deformation sensor 202 and a barrel vertical deformation sensor 203, and the displacement change of the monitoring point includes the radial displacement of the monitoring point, the tangential displacement of the monitoring point and the vertical displacement of the monitoring point. The barrel deformation sensor 109 is fixed to the barrel bracket 108 and is used to perform displacement monitoring on the barrel deformation monitoring body, and obtain the displacement change of the monitoring point, including:

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

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

[0078] In some embodiments, the barrel bracket 108 includes a first barrel bracket 301, a second barrel bracket 302, and a third barrel bracket 303, wherein the first barrel bracket 301 is connected to the bracket fixing portion 111, and the first barrel bracket 301 is arranged along the radial direction of the target containment shell 100, and is used to install the barrel tangential deformation sensor 202.

Figure 2The third support 303 of the barrel body shown in the figure does not overlap with the first support 301 of the barrel body and the barrel body deformation monitoring body 110, which only means that the third support 303 of the barrel body, the first support 301 of the barrel body and the barrel body deformation monitoring body 110 are not on the same horizontal plane, so that the barrel body vertical deformation sensor 203 installed on the third support 303 of the barrel body can monitor the displacement of the barrel body deformation monitoring body 110 relative to the target containment shell 100 in the height direction. This aspect can be referred to Figure 3 The structures of the first barrel support 301, the second barrel support 302 and the third barrel support 303 are not only shown in the figure, the second barrel support 302 can also be arranged in the first barrel support 301 between the barrel deformation monitoring body 110 and the side surface of the target containment shell 100, the third barrel support 303 can be arranged at any position of the first barrel support 301, and the shape of the third barrel support 303 itself is not limited, as long as the installed barrel vertical deformation sensor 203 can monitor the displacement of the barrel deformation monitoring body 110 relative to the target containment shell 100 in the height direction.

[0080] and Figure 2 and Figure 3 The sizes of the various parts shown in the figure are not strictly limited, and the specific sizes of the various parts can be set by technicians in this field 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 a vertex radial displacement, a vertex tangential displacement, and a vertex vertical displacement, and the displacement of the top fixed point is monitored to obtain 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, and obtain the vertex radial displacement;

[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 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, and obtain the vertex vertical displacement.

[0085] In some embodiments, the plumb anchor is set in a damping material under the ground to keep the plumb wire straight, wherein the plumb wire is inelastic. In order to ensure that the plumb wire can maintain its straight state and effectively transmit the deformation information of the top fixed point of the target containment, the plumb anchor is set in a damping material under the ground, and the damping material generally refers to a material that can absorb and dissipate energy, such as rubber, asphalt or water and other special damping materials, so that the plumb anchor can remain stable and reduce the impact of external dynamic loads such as external vibration or wind blowing on the monitoring system.

[0086] In addition, setting the plumb anchor in the damping material under the ground can provide a stable anchor point for the plumb line, ensuring that it can remain taut under various environmental conditions. It helps to reduce the deformation of the plumb line caused by uneven ground settlement, temperature changes or other external factors, thereby ensuring the stability and reliability of the monitoring data.

[0087] In some embodiments, a cantilever beam is provided at the top of the target containment, and the top fixed point is provided at the other end of the cantilever beam, so that there is a preset safety assessment distance between the plumb line and the barrel deformation monitoring body fixed on the plumb line and the side surface of the target containment. Through the cantilever beam and the plumb anchor provided on the ground, the plumb line forms a quadrilateral compared to the side surface of the target containment, so that when the target containment is deformed, resulting in a position change of the top fixed point of the target containment, the displacement change of the top fixed point of the target containment will be transmitted to the ground monitoring submodule provided on the ground through the plumb line. And through the preset safety assessment distance, it is possible to avoid the side surface of the target containment from being squeezed and touching the plumb line when it is deformed, thereby affecting the displacement change of the top fixed point of the target containment transmitted to the ground monitoring submodule provided on the ground through the plumb line.

[0088] In some embodiments, the barrel deformation sensor includes an optical displacement sensor, and the barrel deformation monitoring body includes a monitoring hexahedron, and the optical displacement sensor is used to obtain the displacement change of the monitoring point of the monitoring hexahedron. The light beam emitted by the optical displacement sensor is irradiated on a specific surface of the monitoring hexahedron. When the target containment shell is deformed, the relative position of the barrel support and the monitoring hexahedron will also change, resulting in a corresponding displacement of the reflected light beam. By detecting with the optical displacement sensor, the displacement change of the barrel deformation monitoring body relative to the barrel support can be accurately obtained. In the case where the barrel deformation sensor includes a barrel radial deformation sensor, a barrel tangential deformation sensor and a barrel vertical deformation sensor, the barrel deformation monitoring body is a monitoring hexahedron, and each optical displacement sensor can irradiate the emitted light beam on three different specific surfaces of the monitoring hexahedron, so that the displacement change of the barrel deformation monitoring body relative to the barrel support in three different directions can be better obtained.

[0089] In practical applications, the size of the barrel deformation monitoring body needs to meet the requirement as much as possible that when the target containment shell is deformed, the barrel support is driven to move. The barrel tangential deformation sensor arranged on the first barrel support, the barrel radial deformation sensor arranged on the second barrel support and the barrel vertical deformation sensor arranged on the third barrel support can stably monitor the displacement change of the barrel deformation monitoring body, so that the barrel tangential deformation sensor, the barrel radial deformation sensor and the barrel vertical deformation sensor will not be out of monitoring the barrel deformation monitoring body.

[0090] In some embodiments, the barrel deformation sensor further includes a mechanical sensor, which is connected to the barrel deformation monitoring body, monitors the displacement of the barrel deformation monitoring body, and obtains the displacement change of the monitoring point. In this case, the barrel deformation sensor is connected to the barrel deformation monitoring body through a force transmission medium, and the displacement of the barrel deformation monitoring body is indirectly obtained through the force detected by the barrel deformation sensor.

[0091] In some embodiments, the target containment shell includes multiple segmented monitoring areas, each segmented monitoring area is provided with a corresponding plumb line and a deformation monitoring module, wherein when the plumb line and the ground monitoring sub-module of the deformation monitoring module cannot contact the ground, a touchable horizontal plane is used as the setting area of ​​the plumb line and the ground monitoring sub-module.

[0092] Under normal circumstances, one end of the plumb line is fixed to the top of the target containment, and the other end is in contact with the ground through the ground monitoring submodule to monitor the displacement change of the top fixed point relative to the ground. However, in some cases, due to environmental restrictions or the particularity of the containment structure, the ground monitoring submodule set in some segmented monitoring areas may not be in direct contact with the ground. In this case, a touchable horizontal plane can be used as the setting area of ​​the plumb line and the ground monitoring submodule. In this way, the ground end point of the plumb line is fixed on a stable horizontal plane, which can simulate the contact with the ground, so as to monitor the displacement change of the top fixed point relative to this horizontal plane. This horizontal plane can be a platform near the target containment, a special support structure, or any other stable and touchable horizontal surface. With this alternative, the ground monitoring submodule of the deformation monitoring module can be fixed on this horizontal plane, continue to monitor the spatial deformation data of the target containment, collect the displacement change of the top fixed point transmitted by the plumb line, improve the adaptability of the nuclear power containment deformation monitoring device, and ensure that the target containment can be continuously monitored even under complex field conditions.

[0093] In addition, the target containment can be divided into segmented monitoring areas to conduct more accurate monitoring of special areas of concern and improve the pertinence of monitoring. The target containment can be divided into segmented monitoring areas based on external load conditions, such as temperature changes, pressure changes or external shocks.

[0094] See also Figure 4 , Figure 4 is a flow chart of a method for monitoring deformation of a nuclear power containment vessel provided in an embodiment of the present application. Figure 4 The method may include but is not limited to steps S401 to S404:

[0095] Step S401, receiving the displacement change of the top fixed point of the target containment shell transmitted via the plumb line through the ground deformation sensor of the ground monitoring submodule on the ground, and obtaining 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 barrel deformation sensor of the barrel monitoring submodule performs displacement monitoring on the barrel deformation monitoring body, and obtains the displacement change of the monitoring point corresponding to each deformation monitoring position relative to the top fixed point;

[0097] Step S403, performing relative deformation analysis based on the vertex displacement change amount and the corresponding monitoring point displacement change amount to obtain the target monitoring point deformation amount corresponding to each deformation monitoring position;

[0098] Step S404: Perform a comprehensive deformation analysis based on the deformation variables of each target monitoring point to obtain 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 amount of the top fixed point of the target containment shell transmitted via the plumb line on the ground, and obtains the vertex displacement change amount of the top fixed point relative to the ground deformation monitoring body. Since the ground monitoring submodule is set on the ground, when the target containment shell is deformed, it will not affect the position of the ground monitoring submodule, so the setting of the ground monitoring submodule is like a reference point. When the target containment shell is deformed, the deformation amount will affect the top position of the target containment shell to a certain extent. Therefore, when the target containment shell is deformed, the displacement change amount relative to the top fixed point of the target containment shell transmitted via the plumb line relative to the ground deformation monitoring body can be obtained, and then the vertex displacement change amount is detected by the ground deformation sensor of the ground monitoring submodule.

[0100] In step S402 of some embodiments, for each deformation monitoring position, the barrel deformation sensor of the barrel monitoring submodule performs displacement monitoring on the barrel deformation monitoring body, and obtains the displacement change of the monitoring point corresponding to each deformation monitoring position relative to the top fixed point. In some cases, if deformation occurs at individual positions of the side surface of the target containment, such as bulging and collapse, and the deformation does not affect the top fixed point of the target containment, that is, deformation occurs relative to the top fixed point of the target containment, it cannot be monitored by the ground monitoring submodule.

[0101] At this moment, a plurality of deformation monitoring positions can be set at the plumb line by the position corresponding to the side surface of the target containment, and the displacement monitoring of the barrel deformation monitoring body is carried out through the barrel deformation sensor of the barrel monitoring submodule. If the side surface of the target containment is deformed, such as bulging and collapse, the position of the barrel support in the barrel monitoring submodule will be affected, and at this moment, the barrel support will have a displacement variation relative to the barrel deformation monitoring body, and the barrel deformation sensor of the barrel monitoring submodule can detect the displacement variation of the monitoring point. Because the barrel deformation monitoring body is owing to being fixed on the plumb line, one end of the plumb line is arranged at the top fixed point of the target containment, and the other end is arranged at the plumb anchorage that the ground position does not change, the plumb line can transmit the displacement variation of the top fixed point of the target containment, and at this moment, the barrel deformation sensor of the barrel monitoring submodule detects the displacement variation of the monitoring point obtained, i.e., the relative deformation amount that the side surface of the target containment corresponding to each deformation monitoring position occurs relative to the top fixed point of the target containment.

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

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

[0104] The embodiment of the present application receives the displacement variation of the top fixed point of the target containment shell on the ground via the plumb line through the ground deformation sensor of the ground monitoring submodule, and obtains the vertex displacement variation of the top fixed point relative to the ground deformation monitoring body. Then for each deformation monitoring position, the barrel deformation sensor of the barrel monitoring submodule is used to monitor the barrel deformation monitoring body, and obtains the monitoring point displacement variation corresponding to each deformation monitoring position relative to the top fixed point. Then relative deformation analysis is performed based on the vertex displacement variation and the corresponding monitoring point displacement variation, and the target monitoring point deformation amount corresponding to each deformation monitoring position is obtained. Finally, comprehensive deformation analysis is performed based on the deformation amount of each target monitoring point, and the target deformation information of the target containment shell is obtained. It can be seen from this that the present application transmits the displacement change of the top fixed point of the target containment through a plumb wire to obtain the vertex displacement change, thereby obtaining the spatial deformation data of the entire target containment, and then monitors the displacement of the barrel deformation monitoring body at each deformation monitoring position to obtain the displacement change of the monitoring point relative to the top fixed point, thereby obtaining the relative deformation data of the target containment corresponding to each deformation monitoring position, and then performs relative deformation analysis by comprehensively analyzing the vertex displacement change and the monitoring point displacement change to obtain the absolute spatial deformation data of the target containment at each deformation monitoring position.

[0105] See also Figure 5 In some embodiments, the vertex displacement variation includes the vertex radial displacement, the vertex tangential displacement and the vertex vertical displacement, the monitoring point displacement variation includes the monitoring point radial displacement, the monitoring point tangential displacement and the monitoring point vertical displacement, and step S403 may include but is not limited to steps S501 to S503:

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

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

[0108] Step S503: performing relative deformation analysis based on the vertex vertical displacement and the monitoring point vertical displacement to obtain the vertical deformation corresponding to the deformation monitoring position.

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

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

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

[0112] Step S601, performing segmentation processing based on each deformation monitoring position to obtain a deformation monitoring area;

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

[0114] In step S601 of some embodiments, the target containment is divided into a plurality of deformation monitoring areas, each of which includes a certain number of deformation monitoring positions. By performing feature analysis on the deformation variables of the deformation monitoring positions, it is possible to identify deformation monitoring areas that exhibit similar deformation features, thereby dividing them into deformation monitoring areas with a common deformation mode.

[0115] By segmenting each deformation monitoring position, it is helpful to conduct more focused and accurate analysis on areas of special concern. For example, because the environmental factors of the target containment outer surface corresponding to some deformation monitoring positions are different from those of other deformation monitoring positions, it may be based on factors such as temperature, pressure and structure. Therefore, special deformation analysis processing is required for the target containment outer surface corresponding to this part of the deformation monitoring position. More accurate deformation sensors or equipment adapted to environmental factors can be used.

[0116] On the other hand, when installing the nuclear power containment deformation monitoring device, it may also be necessary to perform segmented installation due to the installation environment not allowing it, so that each deformation monitoring position is segmented to obtain multiple deformation monitoring areas.

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

[0118] In addition, deformation source analysis can also involve the evaluation of 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 deal with the deformation, such as strengthening the structure, adjusting the load distribution, or performing repairs.

[0119] Through step S601 to step S602, deformation information about different areas of the target containment can be obtained. The target deformation source area can be obtained by dividing the deformation monitoring area and locating the deformation source, which is helpful to formulate effective maintenance strategies and preventive measures to ensure that the containment structure of the nuclear power plant remains stable and reliable in long-term operation. Through in-depth analysis of the deformation data of the deformation monitoring area, potential structural problems can be discovered and solved in advance, thereby improving the overall safety of the nuclear power plant.

[0120] See also Figure 7 In some embodiments, the nuclear power containment deformation monitoring device provided by the instantiation of the present application is arranged on different side surfaces of the target containment, and the steps after step S404 may include but are not limited to steps S701 to S702:

[0121] Step S701, obtaining target deformation information of each orientation of the target containment;

[0122] Step S702, performing an overall deformation analysis of the containment based on the first number of target deformation information to obtain 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 orientations. Therefore, the nuclear power plant containment deformation monitoring device provided by the instantiation of this application can be set at different orientations of the target containment to collect the target deformation information in each orientation.

[0124] In step S702 of some embodiments, the target deformation information of each orientation is summarized and compared to identify the deformation trend and pattern of the target containment as a whole. By comprehensively analyzing the target deformation information of different orientations, the deformation information of the containment as a whole can be obtained, and the overall deformation information can be obtained. Through the overall deformation analysis, key indicators such as the maximum value, minimum value, average value and uniformity of deformation distribution of the target containment in each orientation can be obtained. It is also possible to simulate the deformation behavior of the target containment by performing finite element analysis on the collected target deformation information of each orientation, and obtain the spatial deformation of the target containment by digital modeling technology. Based on the 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, seismic effects, etc.

[0125] Through steps S701 to S702, the overall deformation information of the target containment can be obtained, and the spatial deformation data of each orientation of the target containment can be obtained, so that the potential problems and risk points of the containment can be identified more accurately, so as to take targeted measures to ensure the safe operation of the nuclear power plant.
