[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0053] The nuclear reactor simulation method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. The data storage system can store data such as the nuclear reactor model and simulation elements of the nuclear reactor model that server 104 needs to process. The data storage system can be integrated on server 104 or placed in the cloud or on other network servers. After terminal 102 obtains the nuclear reactor model to be simulated and its simulation elements, it transmits the obtained nuclear reactor model and simulation elements to server 104 via the network. Further, server 104 receives the nuclear reactor model and its simulation elements, analyzes the received nuclear reactor model and its simulation elements, generates corresponding description files, and converts them into input objects supported by the target simulation software, enabling the target simulation software to simulate the nuclear reactor model. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. Server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0054] In one embodiment, such as Figure 2 As shown, a simulation method for nuclear reactors is provided, which can be applied to... Figure 1 Taking server 104 as an example, the following steps are included:

[0055] S201, obtain the nuclear reactor model to be simulated and the simulation elements of the nuclear reactor model.

[0056] In this embodiment, the nuclear reactor model to be simulated is the model corresponding to the nuclear reactor that needs to be simulated. The simulation elements are the simulation parameters that need to be input when simulating the nuclear reactor.

[0057] Specifically, the terminal transmits the nuclear reactor model to be simulated and its simulation elements to the server via the network; furthermore, the server acquires the nuclear reactor model and its simulation elements transmitted by the terminal.

[0058] S202 generates the functional relationship description file for the nuclear reactor model and the element description file for the simulation elements.

[0059] In this embodiment, the functional relationship description file is a formatted file that describes the functional relationships of the nuclear reactor model to be simulated. The element description file is a formatted file that describes the simulation elements of the nuclear reactor model to be simulated.

[0060] Specifically, after obtaining the nuclear reactor model to be simulated and its simulation elements, based on pre-defined logic, a functional relationship description file describing the functional relationships of the nuclear reactor model is generated for the nuclear reactor model to be simulated; furthermore, an element description file describing the simulation elements of the nuclear reactor model is generated for the simulation elements of the nuclear reactor model.

[0061] One possible approach is to obtain the nuclear reactor model to be simulated and its simulation elements, then input the nuclear reactor model and its simulation elements into a simulation template library, and determine whether there is a simulation model in the simulation template library that matches the nuclear reactor model, and whether there is an element description file that matches the simulation elements of the reactor model.

[0062] Optionally, if a simulation model matching the nuclear reactor model exists, the functional relationship description file of the simulation model matching the nuclear reactor model is obtained; the functional relationship description file of the simulation model is modified to obtain the functional relationship description file of the nuclear reactor model.

[0063] Specifically, if a simulation model matching the nuclear reactor exists in the simulation template library, the functional relationship description file of the simulation model is obtained; furthermore, based on the functional relationship of the nuclear reactor model, the functional relationship description file of the simulation model is modified to obtain the functional relationship description file of the nuclear reactor model.

[0064] Optionally, if a feature description file matching the simulation features of the nuclear reactor model exists, then the feature description file matching the simulation features of the nuclear reactor model is obtained; furthermore, based on the simulation features of the reactor model, the feature description file matching the simulation features of the nuclear reactor model is modified to obtain the feature description file of the simulation features of the nuclear reactor model.

[0065] S203 converts the functional relationship description file and element description file of the nuclear reactor model into input objects supported by the target simulation software, and then uses the target simulation software to simulate the input objects.

[0066] In this embodiment, the target simulation software is the software that simulates the nuclear reactor model to be simulated. The input objects supported by the target simulation software are those that can be input into the target simulation software and recognized by the target simulation software.

[0067] Specifically, after obtaining the functional relationship description file and element description file of the nuclear reactor model to be simulated, the functional relationship description file and element description file are converted based on the pre-set logic to obtain input objects that can be recognized by the target simulation software. Furthermore, the converted input objects are input into the target simulation software so that the target simulation software can perform simulation processing on the input objects.

[0068] It should be noted that different nuclear reactor simulation software supports different input objects. This solution can convert functional relationship description files and element description files into input objects that can be recognized by the target simulation software, thereby improving the adaptability to nuclear reactor simulation software.

[0069] In the above-mentioned nuclear reactor simulation method, by acquiring the nuclear reactor model to be simulated and the simulation elements of the simulation model, a functional relationship description file and an element description file of the nuclear reactor model are generated respectively. Furthermore, the functional relationship description file and the element description file are converted into input objects supported by the target simulation software, so that the target simulation software can simulate the input objects. This realizes the standardization of the generated nuclear reactor simulation model and enables it to be quickly adapted to nuclear reactor simulation software.

[0070] In one embodiment, such as Figure 3 As shown, the functional relationship description file of the nuclear reactor model generated in step S202 above is refined, specifically including the following steps:

[0071] S301, based on the type of nuclear reactor model, generates the corresponding intermediate diagram.

[0072] The intermediate diagram is either a simulation flowchart or a structural relationship diagram.

[0073] In this embodiment, the simulation flowchart is a flowchart generated based on a modular nuclear reactor model, describing the functional relationships of the nuclear reactor model. Specifically, it describes the relationships between various components in the nuclear reactor model. Nodes in the flowchart describe the type and state of each component, and unidirectional connecting lines describe the data or state transfer between components. The structural relationship diagram, on the other hand, is a structural diagram generated based on a non-modular nuclear reactor model, describing the functional relationships of the reactor model. For example, the structural diagram can be a two-dimensional diagram, describing the abstract geometric style of each component. It connects the relationships between components through undefined connecting lines and can establish parallel multi-channel relationships between components as needed, facilitating the exchange of data or state between connecting lines.

[0074] Specifically, after obtaining the nuclear reactor model, the type of the nuclear reactor model is determined, and a corresponding intermediate diagram is generated based on the type of the nuclear reactor model. Optionally, if the type of the nuclear reactor model is determined to be modular, a simulation flowchart for the nuclear reactor model is generated accordingly; if the type of the nuclear reactor model is determined to be non-modular, a structural relationship diagram for the nuclear reactor model is generated accordingly.

[0075] S302, Based on the intermediate diagram, generate the functional relationship description file of the nuclear reactor model.

[0076] Optionally, if it is determined that no simulation model matching the nuclear reactor model exists in the simulation template library, the intermediate graph generated for the nuclear reactor model is input into a pre-defined neural network model. Based on the intermediate graph, a functional relationship description file describing the functional relationships of the nuclear reactor model is generated. Further, if it is determined that no element description file matching the simulation elements of the nuclear reactor model exists in the simulation template library, the simulation elements of the nuclear reactor model are input into a pre-defined neural network model. Based on the simulation elements of the nuclear reactor model, an element description file describing the simulation elements of the nuclear reactor model is generated. Furthermore, the generated functional relationship description file and element description file of the nuclear reactor model can be added to the simulation template library for subsequent simulation processing of other nuclear reactors.

[0077] In the above embodiments, by determining the type of nuclear reactor model, different intermediate diagrams are generated for different types of nuclear reactor models; furthermore, based on the intermediate diagrams, a functional relationship description file describing the nuclear reactor model is generated, thereby achieving the effect of unified simulation of different types of nuclear reactors and standardizing the simulation models of different types of nuclear reactors.

[0078] In the above embodiments, this embodiment provides a simulation method for a nuclear reactor, which mainly details how to determine the input object. For example... Figure 4 As shown, the specific steps include:

[0079] S401, obtain the nuclear reactor model to be simulated and the simulation elements of the nuclear reactor model.

[0080] S402 generates the functional relationship description file for the nuclear reactor model and the element description file for the simulation elements.

[0081] S403 identifies whether the data format of the data content in the functional relationship description file and element description file of the nuclear reactor model meets the agreed format. If yes, proceed to S404; otherwise, proceed to S405.

[0082] In this embodiment, the data content is the specific content contained in the description file, the data format is the format of the content contained in the description file, and the convention format is the pre-defined format.

[0083] Specifically, after generating the functional relationship description file and element description file of the nuclear reactor model, the data content in the functional relationship description file and element description file can be parsed in blocks to identify whether the data format of the data content in the functional relationship description file and element description file meets the pre-defined convention format.

[0084] S404 uses an automatic adaptation and conversion method to convert the functional relationship description file and element description file of the nuclear reactor model into input objects supported by the target simulation software.

[0085] In this embodiment, the automatic adaptation conversion method is a pre-set conversion method that can automatically adapt and convert description files that meet the data format.

[0086] Optionally, the data format of each block of data content in the functional relationship description file and the feature description file is identified. If the data format of the data content in the functional relationship description file and the feature description file both meet the agreed format, then a pre-set automatic adaptation and conversion method is used to convert the description file into an input object supported by the target simulation software.

[0087] S405 uses a customized conversion method to convert the functional relationship description file and element description file of the nuclear reactor model into input objects supported by the target simulation software.

[0088] In this embodiment, the customized conversion method is to customize a special conversion program for the description file that does not meet the format convention, so as to convert the description file into an input object supported by the target simulation software.

[0089] Specifically, the data format of each data block in the functional relationship description file and the feature description file is identified. If the data format of any data block in the functional relationship description file or the feature description file does not meet the agreed format, then custom programming is performed for the data block in the description file that does not meet the agreed format to convert the description file into an input object supported by the target simulation software.

[0090] S406 uses target simulation software to simulate the input object.

[0091] In the above embodiments, by identifying whether each generated description file meets the agreed format, for description files that meet the agreed format, an automatic adaptation conversion method is used to convert the description file into an input object supported by the target simulation software; for description files that do not meet the agreed format, a customized conversion method is used to customize a dedicated conversion program for the description file to convert the description file into an input object supported by the target simulation software, so that the converted input objects are more comprehensive and accurate.

[0092] In the above embodiments, such as Figure 5 As shown, the simulation of the input object using target simulation software in S203 is further refined, specifically including the following steps:

[0093] S501, verify the correctness of the input object.

[0094] In this embodiment, the input objects may include the functional relationship input objects obtained by converting the functional relationship description file of the nuclear reactor model to be simulated, and the element input objects obtained by converting the element description file of the simulation elements of the nuclear reactor model to be simulated.

[0095] Specifically, based on pre-defined verification rules, the correctness of functional relationship input objects and element input objects included in the input object are verified respectively. Optionally, if the verification fails, the location information of the incorrect input object is output graphically.

[0096] Specifically, if the input object fails validation, the detailed location of the error in the input object is located. The detailed location of the error may include the data row in the input object where the error occurs, and / or the location of the simulation element name. Furthermore, a diagram is generated for the detailed location of the error in the input object, and the diagram is used to provide feedback to the user.

[0097] S502, if the verification is successful, the input object is pre-simulated using the target simulation software.

[0098] In this embodiment, pre-simulation refers to performing pre-simulation processing on the input object by calling the target simulation software.

[0099] Specifically, if the correctness verification passes, the target simulation software is invoked. Based on the target simulation software's own checking logic, pre-simulation processing is performed on the input object. Furthermore, the target simulation software generates a log file. If errors exist in the input object, the generated log file can be used to provide feedback on the error information to the user.

[0100] In this embodiment, the correctness of the input object is first verified. If an error is found, feedback is provided to the user through a diagram. If no error is found, the target simulation software is called to perform a pre-simulation of the input object to further verify the input file. This makes it easier for the user to find and modify the error information in the input file, thereby improving the correctness of the input object.

[0101] In one embodiment, such as Figure 6 As shown, a preferred example of a simulation method for a nuclear reactor is provided, specifically including:

[0102] S601, obtain the nuclear reactor model to be simulated and the simulation elements of the nuclear reactor model.

[0103] S602, determine whether there is a simulation model in the simulation template library that matches the nuclear reactor model; if yes, then execute S603; if no, then execute S605.

[0104] S603, obtain the functional relationship description file and element description file of the simulation model that matches the nuclear reactor model.

[0105] S604 modifies the functional relationship description file and element description file of the simulation model to obtain the functional relationship description file and element description file of the nuclear reactor model; further, execute S609.

[0106] S605 generates intermediate diagrams corresponding to the type of nuclear reactor model; the intermediate diagrams are either simulation flowcharts or structural relationship diagrams.

[0107] S606, based on the intermediate diagram, generates a functional relationship description file for the nuclear reactor model.

[0108] S607, generates the element description file for the simulation elements of the nuclear reactor model.

[0109] S608, add the generated functional relationship description file and element description file to the simulation template library for subsequent simulation processing of other nuclear reactors; further, execute S609.

[0110] S609, identify whether the data format of the data content in the functional relationship description file and element description file of the nuclear reactor model meets the agreed format; if yes, then execute S610; if no, then execute S611.

[0111] S610 uses an automatic adaptation and conversion method to convert the functional relationship description file and element description file of the nuclear reactor model into input objects supported by the target simulation software; further, S612 is executed.

[0112] S611 uses a customized conversion method to convert the functional relationship description file and element description file of the nuclear reactor model into input objects supported by the target simulation software; further, S612 is executed.

[0113] S612, verify the correctness of the input object and determine whether the input object passes the correctness verification; if yes, execute S613; if no, execute S614.

[0114] S613 uses target simulation software to perform pre-simulation of the input object.

[0115] S614 uses a graphical method to output the location information of the incorrect input object.

[0116] The specific processes of S601-S614 described above can be found in the description of the above method embodiments. Their implementation principles and technical effects are similar, and will not be repeated here.
