[0002] A reactor is a device in a nuclear power plant that generates electricity based on certain physical phenomena. Generally, a nuclear power plant needs to establish a reactor model to simulate and observe various physical phenomena achieved by the reactor and optimize the settings of the reactor. Therefore, before establishing the reactor model, it is necessary to determine various physical phenomena involved in the reactor, so that the reactor model can be established based on these physical phenomena to ensure that the reactor model can accurately reflect the key physical phenomena of the reactor.

[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] Reactors are devices in nuclear power plants that generate electricity based on specific physical phenomena. To determine the operational characteristics of a reactor prototype, especially during an accident, simulation and analysis methods are often used to ensure that the experimental model reflects the key physical phenomena of the reactor prototype. This requires identifying the physical phenomena within the reactor prototype to ensure that no omissions are made. The development of reactor safety analysis software also requires the software to simulate, calculate, and analyze the key physical phenomena of the reactor prototype, which also involves identifying the physical phenomena within the reactor prototype. Therefore, developing a reactor physical phenomenon identification method that performs a comprehensive analysis of the physical phenomena within the reactor prototype can achieve comprehensive identification of the physical phenomena within the reactor prototype, which is of great significance for both reactor thermal-hydraulic experiments and the development of reactor safety analysis software.

[0050] Related technologies typically use expert experience to generate a PIRT (Phenomena Identification and Ranking Table) to identify reactor physical phenomena. However, this limited human experience only supports the identification of individual physical phenomena, failing to establish their role and connections within the overall physical process, and thus failing to ensure comprehensive identification of reactor physical phenomena.

[0051] In one embodiment, Figure 1 As shown, a method for acquiring reactor modeling data is provided. This embodiment of the present application uses the method applied to a terminal as an example for illustration. It is understood that the method can also be applied to a server, or to a system including a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0052] Step 101 : hierarchically divide the devices included in each work process involved in the target reactor for physical phenomenon identification, and obtain hierarchical division results corresponding to each work process.

[0053] The target reactor is the reactor for which a model is to be built. Before building the target reactor model, the physical phenomena occurring in the target reactor must be identified. Examples of target reactors include three-loop pressurized water reactors, two-loop pressurized water reactors, lead-bismuth reactors, sodium reactors, and integrated natural circulation reactors. The target reactor includes multiple devices, such as pipelines, separators, and dryers. The target reactor can implement multiple different operating processes, such as a small-breach accident process or a large-breach accident process.

[0054] For the target reactor, each working process is implemented by a plurality of included devices. For each working process, determine the multiple devices involved in implementing the working process, that is, the devices included in the working process. Optionally, according to the roles played by the devices in the working process, further hierarchical division can be performed on each device included in the working process, so as to obtain the hierarchical division result of each device included in the working process. Optionally, the terminal can obtain the device data file corresponding to each working process of the target reactor, and determine the role of each device in the working process according to the parameter data of each device in the device data file.

[0055] Step 102, for the hierarchical division result corresponding to each working process, perform control volume division on the devices included in the lowest level of the hierarchical division result to obtain an initial division result, and the initial division result includes a plurality of first control volumes; wherein, the first control volume includes at least one device with the same structure.

[0056] Among them, the hierarchical division result includes the levels to which each device belongs, and there is an inclusion relationship between the levels. For example, the devices belonging to the first level can be further divided into the second level, and the devices belonging to the second level can be further divided into the third level, where the third level is the lowest level.

[0057] For the devices included in the lowest level, according to the structural characteristics of each device, divide the devices with the same structural characteristics into one control volume to obtain a plurality of first control volumes, that is, each first control volume includes at least one device with the same structure. The division result of each first control volume is the initial division result of the devices included in each working process.

[0058] Step 103, for each initial division result, perform correction processing on the initial division result according to the physical phenomenon identification table to obtain a target division result, and the target division result includes a plurality of second control volumes; wherein, the second control volume includes at least one device with the same structure and related to the same physical phenomenon.

[0059] Among them, the physical phenomenon identification table contains the corresponding relationships between the physical phenomena realized by the target reactor and the devices for realizing each physical phenomenon. The terminal can perform identification and correction on the initial division result according to the physical phenomenon identification table. For each first control volume, divide the devices involved in the same physical phenomenon into the same second control volume to obtain a plurality of second control volumes. Therefore, each second control volume includes at least one device with the same structural characteristics and related to the same physical phenomenon. For example, pipes with the same length and the same physical phenomenon can be divided into one second control volume. The division result of each second control volume is the target division result of the devices included in each working process.

[0060] Step 104: Generate modeling data corresponding to the target reactor according to each second control body and the physical phenomena related to each second control body.

[0061] Among them, for the target division result, generate modeling data corresponding to the target reactor according to the devices included in each second control body and the physical phenomena realized by each second control body. The modeling data includes the corresponding relationship between each control body and each physical phenomenon. According to this modeling data, the model of the target reactor can be further established, so that various physical phenomena that can actually occur in the target reactor can be simulated in the established model.

[0062] In the above method for obtaining reactor modeling data, by performing hierarchical division processing on the devices included in each work process involved in the target reactor to be identified for physical phenomena, through hierarchical division step by step, the multiple devices included in the complex target reactor are initially divided, so that the devices included in the lowest level in the hierarchical division result can be divided into control bodies to obtain an initial division result including multiple first control bodies, realizing the division of the multiple devices included in the complex target reactor into multiple first control bodies with the same structure, establishing the smallest analysis unit for physical phenomenon identification, and realizing the simplification of the physical phenomenon identification of the target reactor from complex to simple. Therefore, the first control bodies in the initial division result can be further corrected according to the physical identification phenomenon table to obtain multiple second control bodies with the same structure and the same realized physical phenomena; since the initial division result is obtained by dividing the multiple devices included in each work process of the target reactor, it comprehensively includes all the devices of the target reactor. By correcting the initial division result according to the physical phenomenon division table, each second control body and the physical phenomena of each second control body are obtained, ensuring the comprehensiveness and accuracy of the physical phenomenon identification of the target reactor, establishing the connection between each physical phenomenon and the entire work process, providing accurate modeling data for establishing the entity model corresponding to the target reactor, and effectively reducing the gap between the established model and the original reactor.

[0063] In one embodiment, as Figure 2 shown, it shows a schematic flowchart of a hierarchical division process provided by an embodiment of the present application; perform hierarchical division processing on the devices included in each work process involved in the target reactor to be identified for physical phenomena, including:

[0064] Step 201: Determine the time process of the target reactor; where the time process includes the start time and end time of the physical phenomena of the target reactor.

[0065] Among them, the working processes of the target reactor occur within a certain time period. Therefore, for the hierarchical division of the devices included in each working process, it should be carried out for the devices involved within this time period. Among them, this time period is the time process of the target reactor, including the start time and the end time. The start time is the time when the physical phenomena of the target reactor begin to occur, and the end time is the time when the physical phenomena of the target reactor end. For example, the time when the break occurs in a small or medium break accident can be used as the start time in the time process, and the time when the residual heat removal heat exchanger is connected can be used as the end time.

[0066] Step 202, within this time process, determine the target state type of each working process; among them, this target state type is a transient type or a steady state type.

[0067] Among them, within this time process, by further determining the target state type of each working process, the devices involved in each working process for realizing different physical phenomena can be determined, and the hierarchical division of each device can be further carried out.

[0068] The parameters of the devices included in each working process, for example, include temperature, pressure, flow rate, power, etc. The target state type can be a transient type or a steady state type. If the parameters change with time within the time process, then the target state type of this working process is a transient type. If the parameters do not change with time within the time process, then the target state type of this working process is a steady state type.

[0069] Step 203, according to the target state type of each working process, perform hierarchical division processing on the devices included in each working process respectively.

[0070] Among them, the working process of the transient type can be divided into multiple stages according to the change of each parameter. For the working process of the steady state type, since each parameter does not change with time, this process does not need to be subdivided.

[0071] Please refer to Figure 3 , which shows a schematic flowchart of hierarchical division processing according to the target state type provided by the embodiment of the present application; according to the target state type of each working process, perform hierarchical division processing on multiple devices included in each working process respectively, including:

[0072] Step 301, for the first working process with the target state type of transient type, use a process division tool to divide this first working process into stages, and obtain multiple phenomenon occurrence stages.

[0073] Step 302, perform hierarchical division processing on multiple devices included in each phenomenon occurrence stage respectively.

[0074] The work process with a transient target state type is recorded as the first work process. The first work process can be divided into multiple phenomenon occurrence stages using a process partitioning tool, and the devices included in each phenomenon occurrence stage can then be hierarchically divided. The process partitioning tool includes physical phenomena corresponding to different time periods within the time process. Based on the different physical phenomena occurring in different time periods, the work process is divided into multiple phenomenon occurrence stages. For example, a small breach accident process can be divided into: the blowdown stage, the natural circulation stage, the loop water seal and purge stage, the core evaporation stage, and the core coolant recovery stage; a large breach accident process can be divided into: the blowdown stage, the refilling stage, and the reflooding stage.

[0075] The terminal can obtain the process partitioning tool and then divide each work process into stages. The process partitioning tool can further form a process partitioning tool file based on a transient process table determined by expert experience. Please refer to Table 1, which shows a transient process table provided by an embodiment of the present application. Each stage division is confirmed by experts and can be adjusted based on expert experience comments. Based on the adjusted transient process table, it can be clarified how to divide transient type work processes, and then a process partitioning tool can be created to divide the first work process into stages, thereby obtaining multiple stages of phenomenon occurrence.

[0076]

[0077]

[0078] Table (1)

[0079] Step 303: For the second working process whose target state type is a steady state type, hierarchical division processing is performed on the multiple devices included in the second working process.

[0080] Among them, the working process with the target state type of steady state is recorded as the second working process. For the second working process, since the parameters do not change with time, the process does not need to be subdivided into multiple phenomenon occurrence stages. Therefore, the devices included in the working process can be directly divided into levels.

[0081] In the embodiment of the present application, different hierarchical division steps are performed for different work processes according to the target state type of each work process, ensuring that the first work process of the transient type in which parameters change with time can be hierarchically divided according to the stage of phenomenon occurrence, thereby achieving orderly division of each device, providing a basis for the subsequent division of the first control body, and improving the efficiency of the division of the first control body, thereby ensuring the accuracy, comprehensiveness and efficiency of the modeling data generated for the target reactor.

[0082] In one embodiment, hierarchical division is performed on the devices included in each work process involved in the target reactor for physical phenomenon identification, including: hierarchical division is performed on the devices included in each work process according to the hierarchical relationship of system, subsystem, equipment, assembly and component; wherein the hierarchical relationship is: the devices included in the system level can be divided into multiple subsystem levels, the multiple devices included in the subsystem level can be divided into the equipment level, the multiple devices included in the equipment level can be divided into multiple assembly levels, the multiple devices included in the assembly level can be divided into multiple component levels, and the component level includes multiple devices.

[0083] The hierarchical relationship, from high to low, is divided into different levels such as system, subsystem, equipment, assembly, and component. Based on this hierarchical relationship, the devices included in each work process are hierarchically divided. Specifically, for the first work process, the devices included in each phenomenon occurrence stage can be hierarchically divided. For example, the equipment included in the blowdown phenomenon occurrence stage is generally divided into the blowdown system. The devices included in the blowdown system can be further divided into subsystems such as the primary loop system, the secondary loop system, and the safety injection system. The primary loop system subsystem can be divided into equipment such as the reactor pressure vessel and internal components, the steam generator, and the main pump. The steam generator equipment can be divided into assemblies such as the tube bundle assembly, the vapor-liquid separator, and the downcomer. The vapor-liquid separator assembly can be divided into components such as the primary vapor-liquid separator, the gravity separator, and the dryer. For the second work process, the devices can be directly hierarchically divided. Optionally, the hierarchical division of the devices of each work process can be carried out according to actual needs, and not every level needs to be reflected. For example, the lowest level of the device division at a certain phenomenon occurrence stage can be equipment rather than components. Based on the hierarchical division results, the lowest level device can be further divided into control bodies. Figure 4 As shown, it shows a hierarchical division schematic diagram provided in an embodiment of the present application.

[0084] In this embodiment, the target reactor is decomposed by hierarchically dividing the devices included in each work process, ensuring that all components of the target reactor are fully analyzed. Each device is hierarchically divided from top to bottom into systems, subsystems, equipment, assemblies, and components, ensuring comprehensive identification of subsequent reactor physical phenomena.

[0085] In one embodiment, the control body division is performed on the devices included in the lowest level in the hierarchical division result, including: according to a pre-set control body division table, the control body division is performed on the devices included in the lowest level in the hierarchical division result, wherein the control body division table contains the design and construction information of the target reactor.

[0086] Among them, the control volume division table contains the involved parameters and construction parameters of each device involved in the construction of the target reactor, that is, the design and construction information of each device. The terminal can determine the structure of each device according to the preset control volume division table. Therefore, according to the control volume division table, the control volume division can be carried out for each device included in the lowest level, and the devices with the same structure are divided into the same control body, so as to obtain a plurality of first control bodies. By dividing a plurality of first control bodies, the smallest analysis unit for identifying the physical phenomena of the target reactor is obtained, and the identification of complex physical phenomena is transformed into the identification of phenomena of a single analysis unit, realizing the simplification from complexity to simplicity in the identification of the prototype physical phenomena of the reactor, and ensuring the comprehensiveness and efficiency of the physical phenomenon identification.

[0087] In one embodiment, as Figure 5 shown, it shows a schematic flow chart of a correction process provided by an embodiment of the present application; for each initial division result, the initial division result is corrected according to the physical phenomenon identification table to obtain the target division result, including:

[0088] Step 501, perform a consistency analysis on each first control body according to the physical phenomenon identification table; wherein, the consistency analysis includes: judging whether each control body realizes a single physical phenomenon.

[0089] Step 502, according to the consistency analysis result, split the control body that realizes multiple physical phenomena into multiple control bodies, or merge multiple control bodies that realize the same physical phenomenon into one control body to obtain the target division result.

[0090] Among them, the correction process of the initial division result according to the physical phenomenon identification table mainly includes performing a consistency analysis on each first control body in the initialization division result, specifically including judging whether each device in each first control body is related to the realization of the same physical phenomenon.

[0091] For each first control body, if the consistency analysis result is to judge that the device contained in the first control body realizes multiple physical phenomena, then according to the realized physical phenomena, the devices that realize the same physical phenomenon are divided into the same second control body. Therefore, the first control body can be divided into multiple second control bodies with the same number of realized physical phenomena. For each first control body, if the consistency analysis result is to judge that the devices contained in multiple first control bodies all realize the same physical phenomenon, then the multiple first control bodies are merged into the same second control body. After correction processing, multiple second control bodies are obtained, wherein each device contained in each second control body realizes the same physical phenomenon. By performing consistency analysis and correction processing on each first control body, the correction range covers all devices involved in the target reactor, ensuring the accuracy of the target reactor physical phenomenon identification range; since the comprehensive physical phenomena of the reactor are covered, the breadth and depth of physical phenomenon identification are guaranteed.

[0092] In one embodiment, modeling data corresponding to the target reactor is generated based on each second control body and the physical phenomena related to each second control body, including: determining the flow direction of the medium between each second control body, and generating the modeling data corresponding to the target reactor based on the flow direction of the medium, each second control body and the physical phenomena related to each second control body; wherein the modeling data is a control body diagram or a control body table.

[0093] Among them, optionally, the terminal can obtain medium flow data, and the flow direction of the medium between each second control body can be determined based on the medium flow data. Therefore, modeling data can be generated based on the flow direction of each medium, the device included in each second control body, and the physical phenomenon realized by each second control body. Among them, the modeling data can be a control body diagram or a control body table. The control body diagram or the control body table contains the connection relationship between each second control body, the physical phenomenon realized by each second control body, and the flow direction of the medium between each second control body. Optionally, the control body diagram can use a single arrow or a double arrow to indicate the flow direction of the medium between the second control bodies, which can be for the flow direction of each medium in the second control body or for the flow direction of the medium between the second control bodies. Figure 6 As shown, it shows a general schematic diagram of a control body diagram provided by an embodiment of the present application, including the connection between part 1, part 2, part 3, part 4, part 5 and part 6. Figure 7 As shown, it shows a schematic diagram of part 1 provided in the embodiment of the present application; Figure 8 As shown, it shows a schematic diagram of part 2 provided in the embodiment of the present application; Figure 9 As shown, it shows a schematic diagram of part 3 provided in the embodiment of the present application; Figure 10 As shown, it shows a schematic diagram of part 4 provided in the embodiment of the present application;Figure 11 As shown, it shows a schematic diagram of part 5 provided by an embodiment of the present application; as Figure 12 shown, it shows a schematic diagram of part 6 provided by an embodiment of the present application.

[0094] In one embodiment, as Figure 13 shown, it shows a schematic flowchart of a process for generating a control volume diagram provided by an embodiment of the present application; including:
