Description

Technical Field

[0001] This invention relates to the technical field of nuclear power safety, and in particular to a method, apparatus, equipment and medium for nuclear power plant commissioning test analysis. Background Technology

[0002] Domestic commercial nuclear power plants have long been constrained by foreign technological systems in the field of commissioning and testing analysis and planning. Since the introduction of the French M310 nuclear power technology, domestic nuclear power plants have consistently used foreign commissioning and verification methods. Although independent programming has been achieved in the commissioning of "Generation II+" nuclear power technology, its core is still a reverse modification based on foreign verification frameworks. With the introduction of "Generation III" nuclear power technologies such as EPR and AP1000, although my country has built the world's first such unit and introduced new foreign commissioning and verification systems again, the design of commissioning tests in domestically developed "Generation III" nuclear power technology has not yet completely broken free from dependence on foreign systems, lacking a systematic theoretical foundation for commissioning and testing analysis. The main shortcomings of current technology are the inability to conduct complete verification analysis based on functions and items, the difficulty in constructing a complete commissioning documentation system, and the inability to achieve structured and digital innovative design of commissioning tests due to limitations of the existing system. Summary of the Invention

[0003] This invention provides a method, apparatus, equipment, and medium for nuclear power plant commissioning test analysis and design, aiming to solve the problem that existing technologies cannot perform complete verification analysis of nuclear power plant systems.

[0027] Please see Figure 1 , Figure 1 This is a flowchart illustrating the nuclear power plant commissioning test analysis method provided in this embodiment of the invention. The nuclear power plant commissioning test analysis method in this embodiment can be applied to commissioning tests of the functions and items of a nuclear power plant. Based on the system design, instrumentation and control design, test requirement analysis and design, etc., of the nuclear power plant, the functions and items requiring commissioning tests are determined. Using the method of this invention, requirements analysis and scheme design are performed, thereby formulating a standard overall strategy and requirements for commissioning test analysis and planning. This verifies the systems installed on-site or the structures completed during construction, ensuring that design assumptions or commitments are met while constructing a complete commissioning integrity analysis result, thus completing the comprehensive verification analysis of the nuclear power plant system.

[0028] Figure 1 This is a flowchart illustrating the nuclear power plant commissioning test analysis method provided in an embodiment of the present invention. As shown in the figure, the method includes the following steps S110-S140.

[0029] S110. Conduct design analysis and screening based on the nuclear power plant system design scheme to determine the target to be analyzed.

[0030] In this embodiment, the nuclear power plant system design scheme is a summary of all design strategies within the nuclear power plant. This includes the equipment used in the nuclear power plant, the different operating functions of different equipment, and important reference materials such as system design manuals, safety feature lists, and safety analysis reports. Design analysis and screening are performed based on the nuclear power plant system design scheme to determine the analysis targets. Specifically, the nuclear power plant system design scheme can be analyzed using a trained deep learning model or computer program. Based on built-in deep analysis algorithms, a comprehensive and in-depth study and analysis of the parameters, performance indicators, and dynamic data of the overall operation process of each component of the nuclear power plant is conducted. By comparing with a preset nuclear power plant safety and operation standard model, the program accurately selects the necessary functions and equipment data for the nuclear power plant system, such as safety functions, operating functions, and equipment, from the design strategies and identifies them as the analysis targets. For example, analyzing the overall system design strategy, the operating functions necessary to support the normal power generation of the unit are selected as the analysis targets. By analyzing and screening targets based on the nuclear power plant system design scheme, analytical targets are identified, providing a basis for subsequent nuclear power plant commissioning analysis and helping to ensure the safe and reliable operation of the nuclear power plant.

[0031] In one embodiment, such as Figure 2 As shown, step S110 further includes steps S111-S114.

[0032] S111. The application equipment in the nuclear power plant system design scheme is statistically analyzed and screened to obtain the corresponding list of items to be analyzed.

[0033] S112. Identify and filter the safety functions, operational functions, and unit-level functions in the nuclear power plant system design scheme;

[0034] S113. Determine the corresponding list of functions to be analyzed based on the safety functions, the operational functions, and the unit-level functions;

[0035] S114. Determine the target to be analyzed based on the list of functions to be analyzed and the list of items to be analyzed.

[0036] In this embodiment, the nuclear power plant system design scheme encompasses a comprehensive plan for the nuclear power plant, from core application equipment such as reactors, steam generators, and turbines to auxiliary equipment such as various pipelines, valves, and sensors. An equipment inventory function is activated to conduct a detailed inventory of the equipment installed and used within the nuclear power plant according to the design strategy, recording information such as name and model and storing it in a database. This includes recording the equipment's name, model, specifications, installation location, and main functions. Next, an equipment screening program is run, using algorithms to screen critical equipment, such as reactor coolant pumps, based on the equipment's importance to nuclear safety, operational criticality, and historical failure data, generating a list of items to be analyzed and clarifying the objects to be analyzed and debugged later. The safety functions are those directly related to ensuring nuclear safety. For example, the reactor's emergency shutdown function can quickly stop reactor operation when abnormal conditions (such as excessively high temperature or abnormal pressure) are detected, preventing nuclear accidents. There is also a radioactive material leakage monitoring and protection function, which can promptly detect and prevent radioactive material leakage into the environment, ensuring the safety of personnel and the environment. The analysis can be based on design basis accidents (DBC-2 / 3 / 4), design extended conditions (DEC-A), and selected severe accident sequences to formulate accident handling strategies, identify safety functions directly used for accident mitigation during accident handling, and thus determine safety functions. Operational functions are those necessary to support normal unit power generation; all functions ensuring normal unit operation fall under the category of operational functions. Specifically, the design conditions that the unit should respond to during normal power generation include all DBC1 conditions; that is, under DBC1 conditions, all functions ensuring normal unit operation fall under the category of operational functions. Simultaneously, based on the defense-in-depth design concept, to prevent the deployment of dedicated systems, some functions for DBC2 conditions are also considered within the category of operational functions. Specific operational and safety functions are not limited, as long as the above-mentioned limitations are met. Unit-level functions refer to the overall functions or tasks that a system or equipment combination can perform at the highest level. These functions typically require the coordinated operation of multiple systems or equipment. Based on the selected safety, operational, and unit-level functions, the program analyzes which functions require detailed analysis. For example, the reactor emergency shutdown function is analyzed, including triggering conditions and response time; the steam generator heat transfer function is analyzed, including heat transfer efficiency and surface condition. These are compiled into a list of functions to be analyzed, providing direction for subsequent inspection and evaluation. The equipment in the list of items to be analyzed is the material carrier that realizes the functions in the list of functions to be analyzed, and the functions in the list of functions to be analyzed are the roles that the equipment in the list of items to be analyzed needs to perform. Both determine the final analysis targets. By selecting the list of functions to be analyzed and the list of items to be analyzed to form the analysis targets, the specific objectives and content of subsequent analysis work are clarified, which helps to carry out targeted design analysis and evaluation of nuclear power plants.

[0037] S120. Perform test requirement analysis on different types of targets to be analyzed to obtain test requirement analysis results, and determine the corresponding test category based on the test requirement analysis results.

[0038] In this embodiment, the test category is determined based on the target to be analyzed, such as functional tests, item tests, etc. Test requirement analysis is performed on different types of targets to be analyzed to obtain test requirement analysis results. Specifically, the test requirements of the list of items to be analyzed in the target to be analyzed and the safety functions, operational functions, and equipment performance in the list of functions to be analyzed are analyzed to generate test requirement analysis results. These results include conclusions such as whether to perform a test, what tests to perform, and the test conditions and system configuration requirements. The design functions such as safety functions and operational functions, as well as the performance of the equipment, must be verified through on-site commissioning tests. On-site verification methods include real tests (R-Real test), envelope tests (E-Envelope test), and transformation tests (T-Transform test). If on-site verification is not possible, it can be replaced by simulation tests, bench tests, DCS platform tests, qualification tests, factory tests, or theoretical calculations. In addition to analyzing individual equipment and functions, the program also performs a comprehensive evaluation of the overall performance of multiple systems or units. Simultaneously, the program collects and analyzes test requirements from other sources, such as regulatory requirements and feedback from historical accidents. By integrating information from multiple sources, the program ultimately generates a comprehensive and detailed test requirements analysis. This result includes a clear conclusion on whether to conduct a test, a detailed description of what type of test to conduct, the required operating conditions, and key information such as system configuration requirements. After obtaining the test requirements analysis results, the program calls the test category determination module. This module matches the various indicators and characteristics in the analysis results with preset test category rules. For example, if the analysis results of a certain item or device show that it is closely related to its operational functions, the program will automatically determine it as a functional test; if the focus is mainly on the performance indicators of the item or device, it will be determined as a performance test. By determining the corresponding test category based on the test requirements analysis results, the program can systematically determine the tests required for different analysis targets, providing clear guidance for subsequent test design.

[0039] In one embodiment, such as Figure 3 As shown, step S120 includes steps S121-S123.

[0040] S121. Determine the corresponding availability conditions and security criteria based on the design information corresponding to the security function;

[0041] S122. Based on the available conditions and the safety criteria, perform a requirement analysis using a preset safety function test requirement analysis method to determine the functional verifiability of the safety function.

[0042] S123. Generate the corresponding security test requirement analysis results for the security function based on the verifiability of the function, wherein the security test requirement analysis results include the debugging environment, test type, test configuration, and test conditions.

[0043] In this embodiment, the available conditions refer to the environmental, operational, and equipment conditions that must be met for the safety function to function properly under normal operation and anticipated abnormal conditions. The safety criteria are a series of standards and requirements established to ensure that the safety function can effectively prevent or mitigate potential dangerous consequences. The corresponding available conditions and safety criteria are determined based on the design information corresponding to the safety functions in the list of functions to be analyzed. Specifically, the design information of the safety function is listed according to the design documents, including the accident conditions that the function should respond to, and its corresponding available conditions and criteria. Based on the available conditions and the safety criteria, a requirements analysis is performed using a preset safety function test requirements analysis method to determine the functional verifiability of the safety function. Specifically, a test requirements analysis is performed based on the available conditions of the safety function to determine the test conditions and test content, and simultaneously determine the test criteria under these test conditions, so as to create test conditions identical to the available conditions corresponding to the safety function under normal operation mode. When generating test conditions, it is determined whether the test conditions will introduce additional transient counts, whether they will cause damage to equipment, structures, or units, and whether they are economically reasonable, thereby determining functional verifiability, i.e., whether a real test can be conducted. If a criterion for a safety function cannot be verified under the operating mode, or if verifying the criterion would generate transient counts or violate technical specifications, making testing impossible under safety analysis conditions, then testing needs to be performed under other operating modes. In this case, the criterion needs to be converted. Finally, based on the functional verifiability, the corresponding safety test requirement analysis results for the safety function are generated. Specifically, different test requirement analysis results are generated depending on whether on-site verification (functional verifiability) is possible. These results include detailed debugging environment information, such as environmental parameters like temperature, humidity, and pressure requirements of the test site; test type, specifying whether it is a real test, a simulation test, or another special type of test; test configuration, including the model, quantity, and connection method of the required equipment; and test conditions, such as specific operating parameters like system operating power, flow rate, and pressure. This embodiment also includes: defining an envelope operating mode to comprehensively verify the criteria for multiple safety functions. Since multiple safety functions may generate some similar criteria, these similar criteria can be analyzed and integrated using a comprehensive reasoning algorithm to obtain the closest envelope criterion. An envelope criterion refers to the comprehensive summarization and generalization of multiple safety function criteria with similar characteristics to form a more general criterion that can cover the requirements of these similar criteria. When developing envelope criteria, the procedure ensures that they meet the safety requirements of all original similarity criteria while also possessing a degree of universality and simplicity to facilitate application and operation in actual experiments. By conducting requirements analysis of safety functions, the verification of these functions is guaranteed to be complete, clear, and reasonable, ensuring that the criteria for the availability of safety functions during commissioning tests can be verified.

[0044] In one embodiment, such as Figure 4 As shown, step S120 includes steps S124-S126.

[0045] S124. Determine the corresponding unit operating conditions, unit system configuration information, and parameter information based on the unit operation design information corresponding to the operating function;

[0046] S125. Based on the unit operating conditions and the unit system configuration information, a requirement analysis is performed using a preset operation function test requirement analysis method to determine the operating conditions and system configuration information of the operation function.

[0047] S126. Determine whether a dynamic test can be conducted based on the operating conditions, system configuration information, and parameter information, and generate corresponding operational test requirement analysis results based on the dynamic test results.

[0048] In this embodiment, the operational functions are those used normally during unit start-up, shutdown, and power operation. Therefore, the verification of operational functions should be based on the completion of individual equipment tests and logic tests for the items of that function. In principle, all functions can be subjected to real dynamic tests, i.e., tests under specific operating conditions and media conditions. The corresponding unit operating conditions, unit system configuration information, and parameter information are determined based on the unit operation design information corresponding to the operational functions in the list of functions to be analyzed. Specifically, all operational functions of the system are screened out according to the unit-level functions of the nuclear power plant system design scheme, and the unit operating conditions and corresponding system configurations used by each operational function are listed, along with the specific parameters characterizing that operational function. The operating conditions and system configuration states required for the verification of this operational function are determined based on the unit operating conditions and corresponding system configurations, and the corresponding test criteria are determined according to different operating conditions and configuration states. Based on the operating conditions, system configuration information, and parameter information, determine whether dynamic testing can be conducted to determine the operating conditions and system configuration information of the operating function. Specifically, the following analysis principles should be followed: a. For functions applicable to multiple operating conditions (standard operating conditions), in principle, only one typical operating condition (such as hot shutdown platform, full-power operation condition) should be selected for actual testing. For some special requirements, such as tests involving adjustments to parameters under multiple operating conditions, tests under each operating condition need to be performed. The selection of typical operating conditions should be considered by the test design from the aspects of functional availability requirements, risk control requirements, and test efficiency requirements, and explained in the verification analysis results. b. When performing verification of the operating function during joint commissioning, in order to ensure that the function is available as early as possible to meet the unit's needs, the test should be performed as early as possible under the operating condition where the function is first put into operation. c. For tests involving the operation of some critical equipment or where the unit has transient risks, pre-tests should be set up at a low platform (temperature, pressure, and power are at lower levels) to assess and reduce the test risks at a high platform (temperature, pressure, and power). d. Only when it is confirmed that the operating conditions and media have no impact on the design criteria verification can the decision not to perform real dynamic verification be considered. For example, under the standard operating conditions of the unit, the temperature, pressure, power, and other parameters of the unit or system have no impact on the verification of the test results; the execution of this test has no impact on the temperature, pressure, power, and other parameters of the unit or system. If a real dynamic test cannot be completed, consider a conversion test, static logic test, or individual unit test for coverage. The relevant analysis process should be described in the verification analysis results. e. For functions triggered by multiple signals but with the same configuration, in principle, only one signal should be selected for a real test, and the rest should only undergo static logic tests. The relevant analysis process should be described in the verification analysis. The steps for generating the corresponding operational test requirements analysis results based on the dynamic test results also include: if different operational functions have mutual influences under different configurations, joint verification should be performed to check the usability of the function under mutual interaction.For functions with identical operating conditions and configurations, joint verification should be conducted to avoid redundant testing. The verification content of operating functions should, as far as possible, follow the nuclear power plant's operating procedures to verify these procedures, and modifications can be made as needed. By generating corresponding operational test requirement analysis results, the performance requirements, system configuration requirements, potential problems, and testing directions for operating functions under different operating conditions are clarified.

[0049] In one embodiment, such as Figure 5 As shown, step S120 further includes steps S127-S129.

[0050] S127. Conduct experimental analysis on the unit-level functions to determine their verification type;

[0051] S128. Determine the verification platform and corresponding verification parameters according to the verification type;

[0052] S129. Generate the corresponding overall test requirement analysis results based on the verification platform and the verification parameters.

[0053] In this embodiment, the unit-level functions include unit-level safety functions and unit-level operational functions. Unit-level safety functions may involve the availability of safety protection functions or configurations of switching operating conditions that do not meet the requirements of normal unit operation. These should be completed as much as possible during the pre-operation test phase before fuel loading. If completion is impossible, the risks and impacts should be fully considered. Unit-level operational functions should also be completed during the pre-operation test phase before fuel loading. Except for those requiring reactor fuel loading startup or those unable to reach their required state, they can be verified during the trial operation phase. The unit-level functions are tested and analyzed to determine their verification type. Specifically, it is determined whether the unit-level functions will be used during unit startup and shutdown. For these unit-level functions, the usage conditions and scenarios can be marked in the overall test design, without the need for dedicated tests. The unit-level functions requiring verification are assessed to determine whether they need joint verification with unit-level functions of multiple systems. If joint verification is required, one or more tests are designed for verification, and the verification type is joint verification; otherwise, it is individual verification. For the remaining uncovered unit-level functions, the analysis examines whether the verification of their sub-functions can fully encompass the unit-level functions. If the analysis results indicate that the functional verification requirements are met, no further testing is needed at the overall testing level. If the analysis results show that the sub-function verification cannot fully prove the usability of the unit-level functions, then one or more tests need to be designed to perform overall verification of the unit-level functions. The verification platform and corresponding verification parameters are determined according to the verification type. Specifically, based on the historical commissioning experience of HAD103 / 02 and inputs, the verification parameters for each testing stage of the unit functions are determined according to the testing phase. These verification parameters include test information corresponding to the verification platform and reactor power. The selection of the verification platform needs to be determined based on information such as loop pressure and temperature limits; unit-level protection settings and automatic action settings; water chemistry adjustment platform; important equipment commissioning / decommissioning platform; reactor power; and the platform set according to the operating procedures. It is understood that the verification parameters also include the test sequence and logical relationship of the unit verification functions, which can be determined through the test sequence procedure and is not limited thereto. The verification platform and the verification parameters are used to generate the corresponding overall test requirements analysis results, which facilitates the test analysis of unit-level functions.

[0054] In one embodiment, such as Figure 6 As shown, step S120 further includes steps S1210-S1212.

[0055] S1210. According to the preset classification method, classify the items and equipment in the list of items to be analyzed into equipment to obtain the equipment classification result, and determine the equipment verification type according to the equipment classification result;

[0056] S1211. Determine the verification type and verifiability of the item / equipment according to the equipment verification type and the preset on-site commissioning test standards.

[0057] S1212. Generate corresponding item test requirement analysis results based on the verification type and the equipment verifiability.

[0058] In this embodiment, the equipment verification type refers to the type of test conducted on the equipment, including single-unit equipment testing and equipment performance testing. Single-unit equipment testing refers to tests that can be performed independently without requiring the operation of other equipment in the system (excluding power supply, air supply, and instrumentation). Examples include valve testing and motor testing. Equipment performance testing refers to tests that require the operation of other equipment in the system and cannot be performed independently; examples include heat exchanger performance testing and pump low-flow testing. The equipment in the list of items to be analyzed is classified according to a preset classification method to obtain equipment classification results. The equipment verification type is then determined based on these classification results. Specifically, a comprehensive and detailed statistical analysis is conducted on all equipment to ensure that all equipment to be analyzed is included in the statistical scope. Based on this, the equipment is further classified according to multiple dimensions such as equipment type, operating method, functional classification, and principle type. Equipment using the same testing method as the verification means within the same category is grouped into the smallest classification unit. For example, in valve equipment, gate valves of the same specification, material, and using the same sealing and opening / closing performance testing methods can be classified as a single minimum category. This classification method helps to unify verification standards and improve the efficiency and quality of verification work. Simultaneously, based on the quantity of equipment used in a nuclear power plant, the equipment is further divided into general-purpose equipment and special-purpose equipment. General-purpose equipment refers to equipment widely used in multiple systems or workstations within a nuclear power plant, such as common centrifugal pumps and electric valves; while special-purpose equipment is specifically designed and manufactured for a particular system or function, with a relatively narrow scope of application, such as customized heat exchangers in certain special processes. Classifying the classified equipment involves determining whether it can be tested independently, generating a "can" or "cannot" classification result, and matching the corresponding equipment verification type based on the classification result. The verification type and verifiability of the equipment are determined based on the equipment verification type and preset on-site commissioning test standards. Specifically, equipment that meets the following conditions is verifiable and can undergo on-site commissioning tests: the equipment participates in safety functions and has corresponding safety guidelines; the equipment participates in transmission, control, monitoring, or other functions; the equipment performance has not been verified at the manufacturer and needs to be verified on-site; and other equipment that needs to be verified on-site based on experience. If the above conditions are met, but actual equipment operation verification would lead to unnecessary consequences such as system or unit transients or equipment damage, then offline verification, qualification tests, simulation verification, theoretical calculations, etc., can be considered as alternatives, i.e., on-site commissioning tests are not performed. Based on the verification type and equipment verifiability, corresponding item test requirement analysis results are generated. These results show whether the equipment can undergo individual equipment testing and whether on-site verification can be performed. If not on-site verification, the simulation verification scheme design is explained.By generating test requirements analysis results for the generated equipment, the integrity and correctness of equipment manufacturing and installation can be checked, ensuring that its parameters and performance meet the relevant design and manufacturing requirements.

[0059] In one embodiment, such as Figure 7 As shown, step S120 further includes steps S1213-S1214.

[0060] S1213. Determine the scope of special test requirements analysis based on the design features of the preset scheme, preset legal standards, and preset contract requirements;

[0061] S1214. Based on preset legal standards and preset contract requirements, select the special targets to be tested from the unit system reference documents and generate the corresponding special test requirements analysis results.

[0062] In this embodiment, the target to be analyzed includes unit system reference documents, which are design documents related to commissioning test analysis and planning, including but not limited to: system design manuals, safety feature lists, safety analysis reports, operating technical specifications, unit operation guidelines, system operation guidelines, periodic test integrity descriptions, fixed-position test criteria, periodic test guidelines, accident operation guidelines, equipment technical specifications, system measurement and control requirements, etc. It should also typically include test results and corresponding analysis reports from simulation tests, DCS platform tests, bench tests, etc., that have been effective and verified during the design and development or engineering phases. The scope of the special test requirements analysis is determined based on the design features of the preset scheme, unit construction experience, and preset legal standards and contract requirements. Specifically, the design features of the preset scheme are the features of the overall nuclear power plant design scheme, such as the Hualong design features. Nuclear safety guidelines and nuclear safety regulations issued by the National Nuclear Safety Administration (NNSA), such as the HAD series of technical guidance documents, are used as preset legal standards. The pre-defined contract requirements are determined by combining the needs of the nuclear power plant's signed contracts with those of other sources (such as overall instrumentation and control testing and radiation measurement testing). Based on the pre-defined design features, historical construction experience, regulations, or signed contract requirements, the reference documents for the unit system are retrieved and analyzed to generate a scope of specific testing requirements that meets the requirements. Based on pre-defined legal standards and contract requirements, specific testing targets are selected from the unit system reference documents. For example, core physics testing is identified as a specific testing target, and its requirements are analyzed to generate corresponding specific testing requirements analysis results. By identifying the specific testing targets, tests can be conducted from sources other than design functions and object characteristics, ensuring the integrity of the nuclear power plant's commissioning tests.

[0063] In one embodiment, such as Figure 8 As shown, step S120 includes steps S1215-S1218.

[0064] S1215. Based on the item test requirement analysis results of the item list to be analyzed, determine the test category of the item equipment that meets the preset item test standards as the item test category;

[0065] S1216. Based on the test requirement analysis results corresponding to the list of functions to be analyzed, the test category of the operating function that meets the preset functional test standard is determined as the functional test category, wherein the functional test category includes operating function test and safety function test;

[0066] S1217. Based on the test requirement analysis results corresponding to the list of functions to be analyzed, the test category of the operating function that meets the preset unit test standard is determined as the overall test;

[0067] S1218. Classify the test categories of the special targets to be tested in the special test requirements analysis results as the special tests.

[0068] In this embodiment, the test categories include item-based tests, functional tests, overall tests, and specific tests. Item-based tests focus on individual devices / components, checking whether their installation status and configuration meet the basic requirements of system testing, and verifying the integrity and correctness of equipment manufacturing and installation to ensure that parameters and performance meet design and manufacturing standards. Some equipment tests (such as valves, motors, instrumentation cabinets, and electrical panels) can be verified independently; some performance tests (such as heat exchangers and pumps) require system or support system cooperation. System flushing, as a cleanliness verification test for process piping and equipment after installation, is closely related to equipment testing and is also classified as an item-based test. Functional tests focus on a specific system function, checking whether the system's operating parameters and performance meet the system design requirements under its design conditions, transition conditions, and simulated conditions. Typical functional tests include flow and pressure loss measurement, servo system linkage and parameter optimization, trial operation under specific range conditions, and electrical panel charging. Another type of test targets equipment or systems controlled by a DCS or other dedicated control system. Through simulation, forced operation, and modeling, it verifies the correctness of monitoring and control channels, as well as the correctness and integrity of control logic. This type of test is called logic control and channel testing, belonging to the static verification of system functions and also falling under the category of functional testing. The overall test involves multiple systems or the entire unit, conducting unit startup and shutdown under fuel-loaded or unloaded conditions, or checking the control response and overall performance of multiple systems or units against design requirements under design conditions, transition conditions, or simulated conditions. Typical overall tests include cold-state performance tests, hot-state performance tests, fuel loading and startup tests, sequential tests, turbine generator set tests, and containment performance tests. Based on the different test objects and scopes, the varying sources of test requirements, and the historical records of nuclear power plant commissioning, the test will examine whether the equipment meets the preset test standards, and whether the operating functions meet the preset functional test standards and preset unit test standards to determine the corresponding test category. The item testing standards, functional testing standards, and unit testing standards can be determined based on the aforementioned item-type tests, functional tests, and overall tests, without any limitations. Determining the test categories for different list contents facilitates the design of corresponding subsequent commissioning plans. The test categories include specialized tests, which refer to tests from sources other than verifying design functions and item characteristics. The sources of specialized tests mainly fall into legal standards, contractual requirements, and other sources (such as design requirements). For example, typical specialized tests include fluid vibration tests, pipeline vibration measurement tests, pressurizer swell tube thermal stratification tests, and radiation measurement tests. The specific targets to be tested can be directly classified as specialized experiments.In addition, this embodiment also includes functional tests, which include operational function tests and safety function tests. Safety functions are the system's safety features, while operational functions are those used normally during unit start-up, shutdown, and power operation. Therefore, tests that examine safety and operational functions are the corresponding safety function tests and operational function tests. Target functions that meet preset operational test standards (e.g., engine start function, network communication function, etc.) are selected from the operational test requirements analysis results. The test categories corresponding to these target functions are categorized as operational function tests (e.g., performance testing, durability testing, environmental testing, etc.). Target functions that meet preset safety test standards (e.g., emergency braking function, overpressure protection function, etc.) are selected from the safety test requirements analysis results. The test categories corresponding to these target functions are categorized as safety function tests (e.g., fault injection testing, Safety Integrity Level (SIL) testing, risk assessment testing, etc.). The preset operational test standards and preset safety test standards can be set according to the specific scope of safety and operational functions, and are not limited thereto. Further categorizing safety functions facilitates more refined test analysis of the nuclear power plant in the future.

[0069] S130. Based on the test requirements analysis results of the target to be analyzed and the corresponding test category, design a scheme to determine the corresponding target test scheme, and design a test strategy based on the target test scheme to determine the target test strategy.

[0070] In this embodiment, the target test plan is a test method designed for each target to be analyzed. The target test strategy is formed by summarizing different test plans according to a certain logical order and different test stages and test windows. Based on the test requirement analysis results of the target to be analyzed and the corresponding test category, a plan is designed to determine the corresponding target test plan. For example, based on the test requirement analysis results, for those requiring on-site commissioning and verification tests, a preliminary test plan is designed using a pre-set large model according to the test category. After the test plan design is completed, the large model is optimized to avoid redundant and repeated tests, reduce transients and equipment actions, thereby determining the final target test plan. The target test plan is further improved according to the test sequence to determine the target test strategy. For example, it is sorted according to rules such as local to overall, equipment to system, and individual units to combined units, and the target test logic is determined based on the sorting. By determining the corresponding target test plan, the target test strategy is designed and determined to complete the overall analysis and planning of the nuclear power plant, providing important data support for its commissioning analysis.

[0071] In one embodiment, such as Figure 9 As shown, step S130 includes steps S131-S132.

[0072] S131. Based on the test category and the test requirements analysis results, design a scheme by pre-setting test objectives and pre-setting test design criteria, and obtain test construction information for different test categories;

[0073] S132. Construct the target test plan based on the test construction information.

[0074] In this embodiment, based on the test category and the test requirements analysis results, a test scheme is designed using preset test objectives and preset test design criteria. Specifically, different test schemes are generated according to different test categories using a preset large model. For example, for functional tests, where one test method verifies multiple system functions, if there are envelope, extension, or hierarchical relationships between system functions, a test design targeting only the main functions can be generated. For overall tests, a debugging phase is performed that indicates the applicable test sequence, concisely and accurately describing the verified system functions or the executed test design, thereby obtaining test construction information for different test categories. For example, for single-unit tests of general-purpose equipment, a standard verification procedure can be designed for use in tests of similar equipment. For single-unit tests of specialized equipment, a functional verification test design or a separate test scheme is considered. For equipment performance tests, a functional verification test design is sufficient. If the equipment is involved in safety functions and there are corresponding safety guidelines, the testing of the equipment should be verified in functional testing. Based on the results of the corresponding test requirements analysis, relevant reference information should be determined, such as the required pressure and stress. The target test plan should then be constructed based on the test construction information. This target test plan may include specific information such as test steps, test boundary conditions, acceptance criteria, and safety measures. By systematically integrating test categories, test requirements analysis results, test objectives, and design guidelines, test construction information is obtained, and the target test plan is constructed accordingly, ensuring the scientific rigor, standardization, and safety of the test plan.

[0075] In one embodiment, such as Figure 10 As shown, step S131 further includes steps S1311-S1314.

[0076] S1311. Generate corresponding test content according to preset safety regulations, test principles, and preset test categories;

[0077] S1312. Generate corresponding test result acceptance standards based on preset judgment methods and preset acceptance criteria;

[0078] S1313. Determine the test risk of the target test plan according to the preset risk assessment criteria;

[0079] S1314. Generate the test construction information based on the test content, the test result acceptance criteria, and the test risks.

[0080] In this embodiment, the preset safety regulations are mandatory laws and standards for the verification of functions or equipment or for a certain type of test, such as nuclear safety regulations (e.g., HAF103), industry safety standards (e.g., IEEE 7-4.3.2), and enterprise safety operating procedures. Based on the preset safety regulations, test principles, and the test category, corresponding test content is generated. The test content includes test principles and test steps. Specifically, the test content is set according to the preset safety regulations, and the physical, chemical, or mechanical principles used in the test content need to be explained. If non-standard test data acquisition methods or test result calculation methods are used, they should be explained separately. The test steps are the main contents executed sequentially to complete the test, including system or equipment start-up and shutdown, parameter measurement and recording, and result analysis and calculation. If special instruments, special tools, or temporary devices are involved in the test, they also need to be described in the test content. If the test category is the item-type test, it is generally designed with reference to commissioning test guidelines, common specifications, or industry standards. For single-unit equipment tests of general-purpose equipment, a standard verification procedure is usually designed for use in tests of similar equipment. For individual equipment testing of specialized equipment, a functional verification test design or a separately designed test plan should be considered. For equipment performance testing, a functional verification test design is sufficient. If the equipment participates in safety functions and there are corresponding safety criteria, the equipment testing should be verified within the functional testing. If the test category is a general test, for test phases with clear changes in unit state (such as cold functional test phase, hot functional test phase, pre-critical test phase, etc.), tests should be arranged according to the unit state or test platform. If necessary, steps or operations to switch the unit from one state to another can be added. For test phases without clear changes in unit state (such as nuclear loop flushing and opening cold functional test phase, hot functional test preparation phase, etc.), only the test procedures to be performed should be listed; steps or operations to switch the unit from one state to another do not need to be listed. The corresponding test result acceptance criteria can be generated based on the preset judgment method and preset acceptance criteria. Specifically, the preset judgment method is mainly set based on the specific requirements of the design function, and it mainly includes four types: action check, system parameter comparison, regulation performance, and phenomenon confirmation. Action checks typically involve confirming the status of certain operations or automatic actions required by the design function, such as whether the first-stage containment isolation valve has activated after the safety injection signal is triggered; system parameter comparisons mainly target parameters with explicit requirements in the design function, such as verifying the opening and closing times of the spray valve; regulation performance checks the performance requirements of open-loop or closed-loop regulation systems, such as the closed-loop regulation performance of the pressurizer level control; phenomenon confirmation refers to phenomena characterizing the design function or unit performance, including physical phenomena or action alarm signals, such as no water splashing out of the evaporator water chamber when the loop level starts and the waste heat discharge pump is activated, or no reactor tripping during the reactor closed-loop control test.The preset acceptance criteria are the acceptance criteria set to evaluate the test results. The verification requirements that the equipment or system involved in the test should meet are usually clearly defined in the form of safety criteria and operational criteria. These criteria should be derived from the requirements or parameters of the functional design. If the test is not conducted under its design conditions, it should be converted accordingly based on the test conditions and test content. Parameters characterizing the safe function under the design baseline conditions and conforming to the principles for determining safety criteria are considered safety criteria. Parameters characterizing system functions but not conforming to the principles for determining safety criteria are considered operational criteria. The final acceptance criteria for the test should be determined by the design department based on the commissioning plan. In addition to safety criteria and operational criteria, preliminary checks, data collection, and verification of contractual requirements can also be set. These tests and their expected values ​​are uniformly defined as "check items." It is understood that the acceptance criteria can be set according to different judgment methods and acceptance criteria, and this is not limited. The test risk of the target test plan is determined according to the preset risk assessment criteria. Specifically, the test plan design needs to conduct risk analysis, assess the rationality of the plan, and control the risk to an acceptable range to ensure feasibility. The preset risk assessment criteria are based on historical experience, industry standards, and regulatory requirements, and are used to define what constitutes an acceptable level of risk. In this embodiment, the preset risk assessment criteria include risk standards based on HSE (Health, Safety, and Environment) risk analysis of the test, the risks of the test system, the risks of the test's impact on the unit's status, the nuclear safety risks of the post-fuel loading test, and the risks of human error in the test. The specific risk standards are not limited, as long as they ensure the test can be conducted smoothly without risk. If the test risk of the target test plan is determined to be unacceptable according to the preset risk assessment criteria, the plan can be modified and redesigned. Early risk identification provides a basis for reasonable preventative measures in subsequent commissioning procedures. The test construction information is generated based on the test content, the test result acceptance criteria, and the test risks, integrating the test content, test result acceptance criteria, and test risks to form test design reference information. By systematically integrating test content, test risks, and other test construction information, the scientific rigor, standardization, and safety of the test design are ensured.

[0081] In one embodiment, such as Figure 11 As shown, step S130 further includes steps S133-S135.

[0082] S133. Design the test logic for the target test scheme according to the preset general test logic design criteria;

[0083] S134. Set the corresponding test window and test stage according to the test logic, unit relevance and preset safety regulations of the target test plan;

[0084] S135. Construct the target test strategy based on the test logic, the test window, and the test phase.

[0085] In this embodiment, the preset general test logic design criteria are a series of test steps or stages that have been determined before the commissioning test. The preset general test logic design criteria are: local before overall, equipment before system, individual before combined, static logic before dynamic response, system before unit, and coreless before core. The test logic design ensures the consistency and repeatability of the test. According to the preset general test logic design criteria, the target test scheme is designed according to the system's test logic. Specifically, the test logic is determined by prioritizing the following factors: System tests should be fully completed before the overall startup test to ensure nuclear safety; specific support systems (such as compressed air, electrical systems, water supply systems, demineralized water supply systems, radioactive waste management systems, ventilation systems, and drainage systems) should be put into use before other systems to facilitate testing of other systems; certain specific systems (such as fire protection systems, radiation protection systems, emergency power systems, and radioactive waste management systems) should be available to ensure that other systems can be tested without endangering personnel, the power plant, or nuclear safety; in all commissioning phases, relevant tests should be uniformly arranged and completed to safely proceed to the next phase of the commissioning outline. Based on the test logic of the target test scheme, the unit's relevance, and the preset safety regulations, corresponding test windows and test phases are set. Specifically, the test windows include three categories: single-system test windows, combined test windows, and overall unit startup and commissioning windows. A single-system test window refers to a test window that does not require the use of a primary circuit and does not need to be performed during unit startup and operation. The joint test window refers to the test window that requires the primary loop to be occupied when the reactor core is not loaded with fuel and that the pressure vessel must be open or closed. The overall startup and commissioning window refers to the window for testing during the overall startup and demonstration operation of the unit after the reactor core is loaded with fuel. It can be understood that the test window during nuclear power plant commissioning testing refers to the time period or timing for conducting specific types of commissioning tests. Based on the test logic of the target test plan, the unit's relevance, and the preset safety regulations, corresponding test windows and test phases are set. Specifically, the commissioning test type refers to test types such as joint tests and equipment tests, and the test logic refers to the steps and principles followed when conducting various commissioning tests. This ensures the orderly conduct of the tests and the accuracy of the results. Unit relevance refers to the degree of correlation between various systems or equipment in the overall operation of the unit. Systems or equipment with high relevance require more caution during commissioning to avoid unnecessary impact on other systems or equipment. Their coordinated work is crucial for improving the overall performance of the unit.Based on the commissioning test type, test logic, unit relevance, and joint test objects, a large model is used for decomposition and analysis to determine single-system test windows for performing equipment tests, logic and control channel tests, and system tests that do not occupy a primary loop and are unrelated to the unit's state; joint test windows for joint tests that require occupying a primary loop and perform system tests and overall tests; and unit startup and commissioning windows for primarily performing system tests and overall tests. Unit startup and commissioning primarily perform system tests and overall tests, but may also include certain equipment tests. Based on the single-system test windows, joint test windows, and commissioning windows, a preset test window is determined, consisting of the aforementioned different types of windows. The test phases are divided according to the "Safety Regulations for Commissioning and Operation of Nuclear Power Plants" and the "Commissioning Procedures for Nuclear Power Plants." Based on the test sequence, test windows, and test phases, a target test strategy with the analyzed objectives is constructed. By determining the target test strategy, various tests can be conducted efficiently and accurately, providing strong support for unit commissioning and operation.

[0086] S140. Summarize and compile the proposed solutions according to the target test strategy to generate the overall technical document for nuclear power plant commissioning.

[0087] In this embodiment, the overall technical document for nuclear power plant commissioning is a complete technical document that guides the writing of commissioning documents. After analyzing the object to be commissioned according to the corresponding test plan, a target test strategy is generated. Based on the target test strategy and other technical documents (such as system commissioning outline, system safety guidelines, commissioning test guidelines, etc.), and following the requirements of HAD103 / 02 and other regulatory documents issued by the Nuclear Safety Administration, the overall technical document system for commissioning is constructed. By generating the overall technical document system for commissioning, it can be used to guide the analysis and planning of commissioning tests for functions and items, which is conducive to the structuring and digitization of commissioning tests, facilitates the management of commissioning activities during the nuclear power plant commissioning phase, and effectively improves commissioning quality and efficiency.

[0088] In one embodiment, step S140 further includes step S141.

[0089] S141. Based on the target test strategy and the preset guidance documents, technical documents are written to generate the overall technical document for nuclear power plant commissioning. The overall technical document for nuclear power plant commissioning includes commissioning procedures, system commissioning outline, system safety criteria, commissioning test guidelines, and unit commissioning outline.

[0090] In this embodiment, the overall technical documentation system for nuclear power plant commissioning includes commissioning integrity analysis, commissioning procedures, system commissioning outline, system safety criteria, commissioning test guidelines, and unit commissioning outline. These technical documents must be prepared with reference to HAD103 / 02 (Nuclear Power Plant Commissioning Procedures) and relevant guidance documents from the Nuclear Safety Administration. Based on the target testing strategy and pre-set guidance documents, technical documents are written to generate the overall technical documentation system for nuclear power plant commissioning. Specifically, based on the target testing strategy, checks or tests are selected for items related to the execution of design functions, and execution documents (Test Procedures (TP)) are generated based on these tests or checks. The Test Procedures detail the test objectives, test content, acceptance criteria, and test steps. Based on the commissioning test plan, a system commissioning outline is generated for the system. This outline details all tests applicable to a specific system or function and their order of execution. The system commissioning outline must enable the test manager to easily and clearly understand the interfaces, impacts, and interrelationships between various tests without referring to other documents. Simultaneously, system safety criteria are generated, providing a quantitative description of each safety function requiring commissioning and verification within the system and specifying which test procedure it should be verified in. These system safety criteria are qualitatively described in the system safety function list during commissioning integrity analysis and finalized during the system commissioning outline design process. To facilitate oversight by nuclear safety regulatory authorities, commissioning test guidelines describing the acceptance items, methods, content, and procedures for widely conducted equipment tests (such as pump, fan, and heat exchanger tests) or general tests (such as system flushing and vibration measurement tests) during commissioning can be generated separately for each system. A unit commissioning outline is also generated, which is a chapter in the final safety analysis report of the nuclear power plant and is one of the licensing documents. The requirements for writing the unit commissioning outline follow HAD103 / 02 and other regulatory documents issued by the Nuclear Safety Administration. Generating this overall technical document system for nuclear power plant commissioning can guide the commissioning test verification of functions and items, facilitating the structured and digitalized commissioning tests, constructing a complete commissioning document system, and thus enabling a complete verification analysis of the nuclear power plant system.

For the sake of convenience and brevity, it will not be repeated here.

[0140] The aforementioned nuclear power plant commissioning and testing analysis device can be implemented as a computer program, which can perform tasks such as... Figure 13 It runs on the computer device shown.
