Description

Technical Field

[0001] The present application relates to the field of reactor thermal hydraulic testing, and in particular to a method, apparatus, computer equipment, storage medium, and computer program product for determining the scale of a reactor test model. Background Art

[0002] With the development of the field of reactor thermal-hydraulic testing, a series of experimental research work needs to be carried out in the processes of reactor development, safety review, optimization and improvement.

[0003] Traditionally, to capture the overall response characteristics of a reactor prototype, especially under accident conditions, a comprehensive test model is typically constructed to conduct corresponding experimental research. Due to the large power, flow rate, and geometric dimensions of a reactor prototype, it is generally difficult to construct a comprehensive test model of the same scale. Therefore, the parameters of the comprehensive test model are typically derived based on a specific scaling method. In previous designs of comprehensive test models for reactors, there was no clear method for selecting test model parameters, and selection was primarily based on experience. This resulted in significant errors when the test model was subsequently used for experimental research. Summary of the Invention

[0052] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0053] The method for determining the scale of a reactor test model provided in an embodiment of the present application can be applied to a terminal or a server. Specifically, the method is described by taking the application to a terminal as an example. The terminal determines a target reactor and obtains the test demand analysis results corresponding to the target reactor under the test conditions; obtains a test model to be constructed corresponding to the target reactor, and the power ratio and volume ratio between the test model to be constructed and the target reactor; based on the power ratio, the volume ratio and the modeling analysis method corresponding to the test demand analysis results, determines multiple groups of modeling ratio combinations corresponding to the test model to be constructed; performs feasibility analysis processing on each group of modeling ratio combinations, and selects a target modeling ratio combination based on the processing results; determines the overall scale parameters of the test model to be constructed based on the power ratio, the volume ratio and the target modeling ratio combination. Among them, the terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server can be implemented as a standalone server or a server cluster consisting of multiple servers.

[0054] In one embodiment, Figure 1 As shown, a method for determining the scale of a reactor test model is provided, which is described by taking the application of the method to a terminal as an example, and includes the following steps:

[0055] Step S202: determining a target reactor and obtaining a test requirement analysis result corresponding to the target reactor under test conditions.

[0056] Among them, the reactor may refer to a nuclear reactor, which refers to a device that can realize the utilization of nuclear energy. Depending on the coolant material, the types of reactors are different. Specifically, the reactors may include water-cooled reactors (pressurized water reactors, boiling water reactors, heavy water reactors), gas-cooled reactors (helium, carbon dioxide, etc.), and liquid metal-cooled reactors (sodium, lead-bismuth alloy, etc.). The target reactor is any one of the reactors selected by the terminal from various reactors based on the actual needs of the user.

[0057] A test condition refers to one of the operating conditions of the target reactor under a specific test content. Different test contents may have different corresponding test conditions, and the same test content may be subdivided into multiple test conditions. For example, if the test content is a full-site power outage accident, the test condition may be a full-site power outage condition at full reactor power or a calculated power outage condition during a reactor shutdown. The test analysis result refers to the result obtained by the terminal after performing a characteristic analysis of parameters related to the target reactor (such as the target reactor's structural parameters and the target reactor's process flow) under the test condition.

[0058] Step S204 : obtaining a test model to be constructed corresponding to the target reactor, and a power ratio and a volume ratio between the test model to be constructed and the target reactor.

[0059] Among them, the test model to be constructed refers to the overall effect test model corresponding to the target reactor to be constructed by the terminal. After the terminal determines the overall scale parameters of the test model to be constructed, it can construct the test model based on the overall scale parameters. Finally, the corresponding test research work can be carried out through the test model.

[0060] The power ratio between the test model to be constructed and the target reactor refers to the ratio between the power of the test model to be constructed and the power of the target reactor, and the volume ratio refers to the ratio between the volume of the test model to be constructed and the volume of the target reactor.

[0061] In one embodiment, obtaining the power ratio and volume ratio of the test model to be constructed and the target reactor includes: obtaining an expected power value of the test model to be constructed; obtaining an actual operating power value of the target reactor; obtaining the power ratio of the test model to be constructed and the target reactor based on the ratio of the expected power value to the actual operating power value; and determining the volume ratio based on the power ratio.

[0062] Among them, the expected power value can refer to the power to be achieved by the set test model to be constructed. The expected power value can be adaptively adjusted according to the type of target reactor, the test operating conditions of the target reactor, etc., and can also be determined by referring to the power supply scale of existing test models of the same type. The actual operating power value of the target reactor can refer to the maximum output power that the target reactor can achieve. The terminal can obtain the expected power value and the actual operating power value, and determine the power ratio between the test model to be constructed and the target reactor based on the expected power value and the actual operating power value.

[0063] After determining the power ratio, the terminal can determine the volume ratio based on the correspondence between the power ratio and the volume ratio. Specifically, the terminal can combine the H2TS (hierarchical two-way proportional modeling) analysis method to obtain the correspondence between the power ratio and the volume ratio, thereby determining the volume ratio between the test model to be constructed and the target reactor. Since the actual situation of the target reactor is taken into consideration when determining the power ratio and volume ratio, it can be ensured that the final test model can meet the test requirements and is feasible.

[0064] Step S206 : determining a plurality of groups of modeling ratio combinations corresponding to the test model to be constructed based on the power ratio, the volume ratio, and the modeling analysis method corresponding to the test requirement analysis result.

[0065] Among them, modeling analysis refers to the proportional analysis of the model to be built and the target reactor by the terminal. The modeling analysis method is selected according to the results of the test demand analysis. Among them, the modeling analysis methods can include H2TS modeling method, power volume modeling method, etc. The power volume method is suitable for physical processes with faster transient changes in the research object; H2TS is a modeling method developed for the use of complex multiphase flow systems, which is suitable for modeling analysis of complex physical phenomena, especially natural circulation processes. Therefore, if the analysis process required by the obtained test demand analysis results is relatively simple, the power volume modeling method can be selected. If the analysis process required by the obtained test demand analysis results is relatively complex, the H2TS analysis method can be selected.

[0066] The modeling ratio combination is determined by the power ratio, volume ratio, and modeling analysis method. Each modeling ratio combination may include the modeling ratios of multiple parameters between the test model to be constructed and the target reactor. Specifically, referring to Table 1, there are multiple modeling ratio combinations corresponding to the test model to be constructed:

[0067] Table 1

[0068] combination Power ratio Volume ratio Height ratio Area ratio Diameter ratio Combination 1 1:150.0 1:150.0 1:1.0 1:150.0 1:10.0 Combination 2 1:150.0 1:150.0 1:2.0 1:75.0 1:7.1 Combination 3 1:150.0 1:150.0 1:3.0 1:50.0 1:5.8 Combination 4 1:150.0 1:150.0 1:4.0 1:37.5 1:5.0 Combination 5 1:150.0 1:150.0 1:5.0 1:30.0 1:4.5

[0069] As can be seen from Table 1, the modular ratio combinations include combination 1, combination 2, combination 3, combination 4, and combination 5. The modular ratios in each group include power ratio, volume ratio, height ratio, area ratio, and diameter ratio. In practical applications, due to the diversity of reactors, when constructing the test model to be constructed, it is necessary not only to consider the scale parameters of the test model to be constructed itself, but also to design the scale parameters of the pipelines and equipment included in the test model to be constructed. Therefore, the modular ratio may include but is not limited to the several types involved in Table 1, such as flow ratio, etc.

[0070] In step S208 , feasibility analysis is performed on each set of modular ratio combinations, and a target modular ratio combination is selected based on the processing results.

[0071] Among them, feasibility analysis processing refers to the terminal analyzing whether the initial scale parameters corresponding to each modularization ratio in each set of modularization ratio combinations meet the design requirements of the test model to be constructed, thereby ensuring the feasibility of the test model to be constructed. Through feasibility analysis processing, the processing results are obtained, and the target modularization ratio combination is selected based on the processing results.

[0072] Step S210 : determining the overall scale parameters of the test model to be constructed according to the power ratio, the volume ratio, and the target modeling ratio combination.

[0073] Among them, the overall scale parameters may include parameters such as power, flow, and geometric dimensions of the test model to be constructed. After determining the power ratio, volume ratio, and target modeling ratio combination, the terminal can determine the overall scale parameters of the test model to be constructed.

[0074] In the scale determination method of the above-mentioned reactor test model, the target reactor is determined, and the test demand analysis results corresponding to the target reactor under the test conditions are obtained; the test model to be constructed corresponding to the target reactor, and the power ratio and volume ratio between the test model to be constructed and the target reactor are obtained; based on the power ratio, volume ratio and the modeling analysis method corresponding to the test demand analysis results, multiple groups of modeling ratio combinations corresponding to the test model to be constructed are determined; feasibility analysis processing is performed on each group of modeling ratio combinations, and the target modeling ratio combination is selected based on the processing results; and the overall scale parameters of the test model to be constructed are determined according to the power ratio, volume ratio and target modeling ratio combination. Therefore, on the one hand, the modeling analysis method is determined by the test demand analysis results of the target reactor under actual test conditions, which can make the overall scale parameters of the test model to be constructed meet the test requirements of the target reactor to a certain extent. On the other hand, the feasibility analysis of the multiple groups of modeling ratio combinations determined can improve the feasibility of the overall scale parameters of the test model to be constructed. Finally, the overall scale parameters of the test model to be constructed are determined according to the power ratio, volume ratio and target modeling ratio combination, which ensures the standardization and reliability of the overall scale parameters of the test model to be constructed.

[0075] In one embodiment, obtaining the test requirement analysis result corresponding to the target reactor under the test condition includes:

[0076] Acquiring initial design parameters of the target reactor, wherein the initial design parameters include at least one of a process flow, process parameters, or structural parameters of the target reactor;

[0077] Obtaining parameter variation characteristics of the initial design parameters of the target reactor under the test operating conditions;

[0078] Based on the parameter variation characteristics, a test demand analysis result corresponding to the target reactor under the test conditions is obtained.

[0079] Among them, the initial design parameters refer to the prototype design parameters of the target reactor, such as process flow, process parameters or structural parameters. The process flow may refer to the working principles of each subsystem of the target reactor, the flow direction of the working medium, and the action sequence of each system and equipment under various accident conditions. The process parameters may refer to the temperature, pressure, power, flow and other parameters of the target reactor. The structural parameters may refer to the length, height, area, elevation and other parameters of the relevant equipment and pipelines of the target reactor.

[0080] Under different test conditions, the prototype design parameters of the target reactor will also change accordingly. Therefore, the terminal can determine the test demand analysis results by analyzing the parameter change characteristics of the initial design parameters under different test conditions. The test demand analysis results can be obtained by analyzing the physical process of the prototype design parameters of the target reactor. This can ensure that when determining the modeling analysis method in the future, it can be determined in combination with the actual parameter changes of the target reactor, which can improve the standardization of the modeling analysis method.

[0081] In one embodiment, the initial design parameter is the temperature in the process parameter, and the terminal can analyze the temperature change characteristics under the test conditions. Specifically, under the full-field power outage accident condition, the average temperature of one of the loop systems of the target reactor prototype first increases and then decreases with time. The test requirement analysis result can be that it is necessary to simulate the full-field power outage accident condition, and the average temperature of one of the loop systems of the target reactor prototype first increases and then decreases with time.

[0082] In one embodiment, determining a plurality of sets of modeling ratio combinations corresponding to the test model to be constructed based on the power ratio, the volume ratio, and the modeling analysis method corresponding to the test requirement analysis result includes:

[0083] When the power ratio and the volume ratio remain unchanged, a plurality of groups of modular ratio combinations corresponding to the test model to be constructed are determined according to the modular analysis method corresponding to the demand analysis result.

[0084] Among them, when determining multiple groups of modular ratios, the terminal can set the power ratio and volume ratio unchanged, and combine the modular analysis method to determine multiple groups of modular ratio combinations as shown in Table 1 above. As can be seen from Table 1, the power ratio and volume ratio in each modular ratio combination remain unchanged, while the area ratio, height ratio and diameter ratio of each group will change accordingly. Therefore, by determining multiple groups of modular ratio combinations and conducting subsequent comparative analysis, a feasible modular ratio is finally obtained.

[0085] In one embodiment, the determining, when the power ratio and the volume ratio remain unchanged, according to the modeling analysis method corresponding to the demand analysis result, to determine multiple sets of modeling ratio combinations corresponding to the test model to be constructed includes:

[0086] Under the condition that the power ratio and the volume ratio remain unchanged, determining multiple height ratios, multiple length ratios, multiple diameter ratios, and multiple area ratios between the test model to be constructed and the target reactor according to the modeling analysis method corresponding to the demand analysis result;

[0087] Based on the power ratio, the volume ratio, and each of the height ratio, the diameter ratio, and the area ratio, a plurality of groups of modeling ratio combinations corresponding to the test model to be constructed are determined.

[0088] Among them, the height ratio, area ratio and diameter ratio can refer to the modular ratio of the height of the test model to be constructed and the height of the target reactor, or the height ratio of the equipment in the test model to be constructed and the corresponding equipment in the target reactor, or the height ratio of the pipes in the test model to be constructed and the corresponding pipes in the target reactor, that is, the scale parameters of the test model to be constructed itself, and the scale parameters of the equipment, pipes, etc. involved in the test model to be constructed, can all be determined in this application by keeping the power ratio and volume ratio unchanged and then combining them with the modular analysis method.

[0089] Among them, when the power ratio and volume ratio remain unchanged, the terminal can determine a variety of height ratios, length ratios, diameter ratios, area ratios and flow ratios between the test model to be constructed and the target reactor according to the modeling analysis method corresponding to the demand analysis results. For example, when the power ratio is 1:150.0 and the volume ratio is 1:150.0, the height ratio can be 1:1.0, the area ratio can be 1:150.0, the diameter ratio can be 1:10.0, and the flow ratio can be 1:20.0. For example, when the power ratio is 1:150.0 and the volume ratio is 1:150.0, the height ratio can be 1:2.0, the area ratio can be 1:75.0, the diameter ratio can be 1:7.1, and the flow ratio can be 1:25.0. This can increase the diversity of the data, thereby selecting the optimal modeling ratio combination, and effectively improving the accuracy of the overall scale parameters of the test model to be constructed that are subsequently determined.

[0090] In one embodiment, performing feasibility analysis on each set of modular ratio combinations and selecting a target modular ratio combination based on the processing results includes:

[0091] For each set of modeling ratio combinations, the corresponding initial scale parameters are obtained;

[0092] Comparing each of the initial scale parameters with a preset initial scale parameter condition to obtain an initial scale comparison result;

[0093] The initial scale comparison result is a modeling ratio combination corresponding to the initial scale parameters that meets the preset initial scale parameter conditions, which is set according to the processing feasibility, spatial layout, and measuring instrument layout of the test model to be constructed.

[0094] Among them, the initial scale parameter refers to the parameter calculated according to the modularization ratio in the modularization ratio combination. For each modularization ratio in the modularization ratio combination, the corresponding parameter can be calculated. For example, if the area ratio in the modularization ratio combination is 1:75.0, the terminal can combine the actual area of ​​the target reactor to obtain the model area of ​​the test model to be constructed, and the model area can be the initial scale parameter. The preset initial scale parameter condition refers to the condition set for judging whether the initial scale parameter can meet the construction requirements of the model to be constructed.

[0095] Among them, the preset initial scale parameter conditions are set according to the processing feasibility, spatial layout, and measuring instrument layout of the test model to be constructed. Specifically, if the length ratio is the modular ratio of the length of the pipeline in the test model to be constructed and the length of the pipeline of the target reactor, the length of the pipeline in the test model to be constructed is calculated according to the modular ratio. When flange connections are used between the equipment in the test model to be constructed, it is necessary to consider whether the length of the pipeline meets the requirements for arranging flanges and measuring instruments. The selection of the height ratio should take into account the subsequent processing and manufacturing requirements when designing the physical device based on the test model to be constructed, the limitations of the site conditions of the test device, etc.

[0096] In one embodiment, the terminal can obtain the length of the pipeline of the test model to be constructed based on the length ratio. A Venturi flowmeter needs to be arranged on the pipeline to measure the flow rate. The length of the Venturi flowmeter itself and the required length ratio of the front and rear straight pipe sections need to be selected when considering the layout requirements of the Venturi flowmeter (measuring instrument). The flange itself has a certain size. Therefore, when determining the initial scale parameter conditions, it is necessary to consider whether the selected length ratio and diameter ratio can ensure that there is space to arrange the equipment and flange.

[0097] In one embodiment, after selecting the target modular ratio combination based on the processing results, and before determining the overall scale parameters of the test model to be constructed according to the power ratio, the volume ratio, and the target modular ratio combination, the following steps are included:

[0098] Determining target scale parameters of the test model to be constructed based on actual scale parameters of the target reactor and the target modeling ratio combination;

[0099] Based on the preset scale parameter standard value, the target modeling ratio combination is adjusted.

[0100] Among them, the actual scale parameters refer to the scale parameters of the target reactor itself, such as the actual area and actual volume of the target reactor. The target scale parameters refer to the parameters of the test device to be constructed calculated from the modularization ratio in the target modularization ratio combination. The preset scale parameter standard value refers to the scale parameter standard value set for the target scale parameter corresponding to each modularization ratio. When setting the preset scale parameter standard value, it can be set in combination with the standard industrial scale parameter.

[0101] After the terminal determines the target modularization ratio, it can then perform local optimization on the modularization ratio within the target modularization ratio combination. Specifically, the actual scale parameters of the target reactor can be obtained. Then, based on the modularization ratio within the modularization ratio combination, the target scale parameters can be determined accordingly. The target scale parameters can then be compared with the corresponding preset scale parameters to adjust the target modularization ratio combination. For example, based on a diameter ratio of 1 / 7.0 and the actual inner diameter of the pipe of the target reactor of 141mm, the inner diameter of the pipe of the experimental model to be constructed is 20.14mm. Based on the preset scale parameter adjustment value (e.g., 20mm), the diameter ratio can be fine-tuned to 1 / 7.1.

[0102] In another embodiment, Figure 2 As shown, this embodiment involves an optional process of determining the overall scale parameters of the test model to be constructed based on the power ratio, volume ratio and target modeling ratio combination, including the following steps:

[0103] Step S202 : determining candidate scale parameters of the test model to be constructed according to the power ratio, the volume ratio, and the target modeling ratio combination.

[0104] Among them, the candidate scale parameters refer to those obtained by combining the power ratio, volume ratio and target modularization ratio. Specifically, the terminal can determine the power of the test model to be constructed based on the power ratio, and the volume of the test model to be constructed based on the volume ratio. According to the modularization ratios in the target modularization ratio combination, such as the area ratio and flow ratio, the area and flow of the test model to be constructed can be determined.

[0105] Step S204: Based on the candidate scale parameters, analyze the key physical phenomena of the target reactor to obtain phenomenon simulation results.

[0106] Among them, the key physical phenomenon refers to the physical phenomenon that has a high degree of influence on the parameters of the target reactor (such as the lowest water level in the core under a rupture accident). The terminal can simulate the key physical phenomenon based on the candidate scale parameters to obtain the phenomenon simulation results.

[0107] Step S206: If the phenomenon simulation result is inconsistent with the preset phenomenon result, after adjusting the power ratio and volume ratio, return to the step of obtaining the power ratio and volume ratio of the test model to be constructed and the target reactor until the phenomenon simulation result is consistent with the preset phenomenon result.

[0108] Among them, the preset phenomenon results refer to those set according to the characteristics when the key physical phenomenon actually occurs. If the terminal determines that the phenomenon simulation results are inconsistent with the preset phenomenon results, it means that the currently determined candidate scale parameters are deviated. Then, the power ratio and volume ratio can be adjusted, and then the step of obtaining the power ratio and volume ratio of the test model to be constructed and the target reactor can be returned to determine the new candidate scale parameters, and then the key physical phenomenon analysis is performed based on the new candidate scale parameters until the phenomenon simulation results are consistent with the preset phenomenon results.

[0109] Step S208 : taking the candidate scale parameters corresponding to the phenomenon simulation results that are consistent with the preset phenomenon results as the overall scale parameters of the test model to be constructed.

[0110] If the phenomenon simulation result is consistent with the preset phenomenon result, it indicates that the determined candidate scale parameters meet the construction requirements of the test model to be constructed, and the terminal can use the candidate scale parameters as the overall scale parameters of the test model to be constructed.

[0111] Therefore, on the basis of the candidate scale parameters that have been determined by the terminal, the candidate scale parameters are further verified to see whether they meet the requirements by simulating key physical phenomena, thereby ensuring the reliability of the scale determination of the reactor integral effect test model.

[0112] In one embodiment, Figure 3 FIG. 1 is a flow chart of a method for determining the scale of a reactor test model in a specific embodiment.

[0113] In this embodiment, it is first necessary to determine the research object, that is, to determine the target reactor, and then determine the test requirements of the target reactor. Specifically, the terminal can analyze the changing characteristics of the prototype parameters of the target reactor under different test conditions, such as conducting research on a new test device for a full-field power outage accident of a pressurized water reactor, so as to obtain the changing characteristics of the power, flow, pressure, temperature and other parameters of the target reactor under the full-field power outage accident condition, such as the prototype power, flow and other parameters of the reactor and their changing laws under the full-field power outage accident condition.

[0114] Specifically, under the full-power-off accident condition, the average temperature of one of the circuit systems of the target reactor prototype first increases and then decreases with time. The test requirement analysis result may be that it is necessary to simulate the full-power-off accident condition, and the average temperature of one of the circuit systems of the target reactor prototype first increases and then decreases with time. A modeling method corresponding to the requirement analysis result may be selected for subsequent modeling analysis, such as selecting a bidirectional multi-stage proportional analysis (H2TS) method for modeling analysis.

[0115] Furthermore, the terminal can determine the basic modularization ratio of the test model to be constructed. Specifically, the basic modularization ratio can be the power ratio and volume ratio of the test model to be constructed. When preliminarily determining the power ratio of the test model to be constructed, the power supply scale of the existing test model of the same type can be referred to, such as the power ratio is 1:150; the volume ratio of the test model to be constructed is obtained by the modularization method and the power ratio. For example, based on the H2TS method and the power ratio (1:150), the volume ratio of the test model to be constructed is 1:150.

[0116] When determining the modularization ratio, the terminal can set the power ratio and volume ratio unchanged, and combined with the modularization analysis method, multiple sets of modularization ratio combinations can be obtained. The power ratio and volume ratio in each modularization ratio combination remain unchanged, while the area ratio, height ratio and diameter ratio of each group will change accordingly. Therefore, by determining multiple sets of modularization ratio combinations, comparative analysis is performed in the subsequent stage to finally obtain a feasible modularization ratio group. Specifically, when conducting comparative analysis, it is necessary to consider processing feasibility, space layout, measuring instrument layout and other requirements. When flange connection is used between devices, it is necessary to consider whether the length of the pipeline under the length ratio meets the requirements for arranging flanges and measuring instruments; the selection of the height ratio should take into account the processing and manufacturing requirements of the equipment, the limitations of the test device site conditions, etc., thereby determining the target modularization ratio group.

[0117] Furthermore, the terminal locally optimizes the determined target modeling ratio group to obtain modeling ratios such as height ratio, length ratio, diameter ratio, volume ratio, and power ratio of the test model to be constructed, such as fine-tuning the diameter ratio, so that the diameter of the pipe after modeling meets the standard industrial pipe specifications.

[0118] The terminal obtains relevant parameters of the test model to be constructed, such as power, flow rate, geometric dimensions, etc., based on the determined modeling ratio and reactor prototype parameters;

[0119] Finally, the terminal simulates the key physical phenomena according to the relevant parameters of the test model to be constructed, obtains the simulation results, and analyzes the simulation results. If the simulation results of the key physical phenomena are consistent with the actual results of the key physical phenomena, the analysis of the simulation results of the key physical phenomena is completed, and the scale determination process is completed; if the simulation results of the key physical phenomena are inconsistent with the actual results of the key physical phenomena, the basic modeling ratio is adjusted and the relevant parameters of the test model to be constructed are re-determined until the simulation results of the key physical phenomena are consistent with the actual results of the key physical phenomena. The analysis of key physical phenomena can be carried out by theoretical analysis, numerical calculation, preliminary experiments, etc.
