Description

Technical Field

[0001] This application belongs to the field of nuclear power technology, specifically relating to a method, apparatus, and electronic equipment for acquiring nuclear power plant equipment configuration status data. Background Technology

[0002] Nuclear power plant configuration risk management utilizes probabilistic safety assessment (PSA) models to calculate risk indicators based on the actual operating configuration of the power plant, and then conducts risk assessment and management. Practice has shown that configuration risk management is an effective means of controlling risks associated with multiple equipment failures in nuclear power plants, and can significantly improve the scientific rigor and effectiveness of nuclear power plant safety management decisions. Configuration risk management is typically conducted using risk monitoring systems. In specific risk assessments, the completeness and accuracy of the input data on the power plant equipment configuration status directly affect the accuracy of the calculated risk indicators and the overall quality of the configuration risk assessment work.

[0003] Currently, the risk monitoring systems developed and used in domestic nuclear power plants do not fully classify equipment configuration status in the software when acquiring equipment configuration status data. In particular, unavailable equipment configuration status is uniformly classified into the same unavailable type, resulting in insufficient completeness and accuracy of the obtained nuclear power plant equipment configuration status data, which in turn leads to significant errors in the results of nuclear power plant equipment configuration risk analysis. Summary of the Invention

[0004] In view of this, the embodiments of this application are committed to providing a method, apparatus and electronic device for obtaining nuclear power plant equipment configuration status data. By distinguishing between planned unavailability status and random unavailability status when determining the configuration status type of nuclear power plant equipment, the obtained unavailability configuration status data of nuclear power plant equipment is made more complete and accurate, and the error of the results of nuclear power plant equipment configuration risk analysis is reduced.

[0005] The first aspect of this application provides a method for acquiring configuration status data of nuclear power plant equipment. The method includes: determining whether the configuration status type of the nuclear power plant equipment is available or unavailable; if the configuration status type of the nuclear power plant equipment is unavailable, determining whether the configuration status type of the nuclear power plant equipment is planned unavailable or random unavailable; and acquiring configuration status data of the nuclear power plant equipment from multiple data sources based on the configuration status type of the nuclear power plant equipment. The multiple data sources include a nuclear power plant real-time database system, a nuclear power plant operation log system, a nuclear power plant work order management system, a work order isolation system, and a mapping relationship data table between nuclear power plant pre-maintenance items and unavailable equipment.

[0006] In the above scheme, by distinguishing between planned unavailability and random unavailability when determining the configuration status type of nuclear power plant equipment, the classification of equipment unavailability configuration status in the risk monitoring system is accurately sorted out. This allows the acquired configuration status data of nuclear power plant equipment to distinguish between the random and planned differences in unavailability status, fully determine the corresponding equipment configuration status type in the nuclear power plant equipment configuration risk calculation, improve the completeness and accuracy of the acquired nuclear power plant equipment configuration status data, and provide accurate equipment configuration status data input for the nuclear power plant risk monitoring system.

[0007] In one specific embodiment of this application, after determining whether the configuration status type of the nuclear power plant equipment is a planned unavailability or a random unavailability if the configuration status type is unavailable, the method further includes: if the configuration status type of the nuclear power plant equipment is a planned unavailability, determining the work task category that caused the nuclear power plant equipment to be in a planned unavailability state, where the work task category includes corrective maintenance, preventive maintenance, and periodic testing. The above-mentioned acquisition of nuclear power plant equipment configuration status data from multiple data sources based on the configuration status type includes: acquiring the nuclear power plant equipment configuration status data from the nuclear power plant work order management system, the work order isolation system, and the mapping relationship data table based on the nuclear power plant equipment configuration status type.

[0008] In one specific embodiment of this application, the above-mentioned determination of the work task category that causes nuclear power plant equipment to be in a planned unavailable state includes: if the nuclear power plant has planned work orders with work order isolation instructions, the target work order entry is located in the work order management system by the work order isolation number, and the work task type information in the target work order entry is read to determine the work task category that causes the nuclear power plant equipment to be in a planned unavailable state; if the nuclear power plant does not have planned work orders with work order isolation instructions, the mapping relationship data table between the corresponding nuclear power plant pre-maintenance entries and unavailable equipment is determined, and the work task category that causes the nuclear power plant equipment to be in a planned unavailable state is determined by the unique pre-maintenance code in the mapping relationship data table.

[0009] In one specific embodiment of this application, the above-mentioned method of obtaining configuration status data of nuclear power plant equipment from multiple data sources according to the configuration status type of nuclear power plant equipment includes: if the configuration status type of nuclear power plant equipment is available, then selecting the nuclear power plant real-time database system as the data source from multiple data sources, and obtaining the configuration status data of nuclear power plant equipment from the nuclear power plant real-time database system.

[0010] In one specific embodiment of this application, the above-mentioned method of obtaining configuration status data of nuclear power plant equipment from multiple data sources according to the configuration status type of nuclear power plant equipment includes: if the configuration status type of nuclear power plant equipment is a planned unavailable status, then selecting the nuclear power plant work order management system and work order isolation system as data sources from multiple data sources, and obtaining the configuration status data of nuclear power plant equipment from the nuclear power plant work order management system and work order isolation system.

[0011] In one specific embodiment of this application, the above-mentioned method of obtaining configuration status data of nuclear power plant equipment from multiple data sources based on the configuration status type of nuclear power plant equipment includes: if the configuration status type of the nuclear power plant equipment is random unavailable, then determining whether the nuclear power plant real-time database system includes equipment fault feedback data points; if the nuclear power plant real-time database system includes equipment fault feedback data points, then selecting the nuclear power plant real-time database system as the data source and obtaining the configuration status data of the nuclear power plant equipment from the nuclear power plant real-time database system; if the nuclear power plant real-time database system does not include equipment fault feedback data points, then determining whether the nuclear power plant operation log system includes unavailable information of the nuclear power plant equipment; if the nuclear power plant operation log system includes unavailable information of the nuclear power plant equipment, then selecting the nuclear power plant operation log system as the data source and obtaining the configuration status data of the nuclear power plant equipment from the nuclear power plant operation log system; if the nuclear power plant operation log system does not include unavailable information of the nuclear power plant equipment, then selecting the nuclear power plant work order management system as the data source and obtaining the configuration status data of the nuclear power plant equipment from the nuclear power plant work order management system.

[0013] A third aspect of this application provides an apparatus for risk analysis of nuclear power plant equipment configuration. The apparatus includes a judgment module and an acquisition module. The judgment module determines whether the configuration status of the nuclear power plant equipment is available or unavailable. If the configuration status is unavailable, it further determines whether the configuration status is planned or random. The acquisition module retrieves configuration status data of the nuclear power plant equipment from multiple data sources based on the configuration status type. These multiple data sources include a real-time nuclear power plant database system, a nuclear power plant operation log system, a nuclear power plant work order management system, a work order isolation system, and a mapping table between nuclear power plant pre-maintenance items and unavailable equipment.

[0021] Figure 6 The diagram shown is a block diagram of an electronic device provided in one embodiment of this application. Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Figure 1 The diagram shown is a flowchart illustrating a method for acquiring nuclear power plant equipment configuration status data according to an embodiment of this application. The execution entity of this method can be a processor or a server, etc. Figure 1As shown, the method includes the following steps S100 to S300.

[0024] S100: Determine whether the configuration status of nuclear power plant equipment is available or unavailable.

[0025] Specifically, if nuclear power plant equipment is in an operating / on or shut-down state, its configuration status can be determined as available. Additionally, the range of unavailable equipment can be automatically determined by reading equipment information in the work order isolation instructions that is currently tagged.

[0026] S200: If the configuration status type of nuclear power plant equipment is unavailable, determine whether the configuration status type of nuclear power plant equipment is planned unavailable or random unavailable.

[0027] Specifically, careful research revealed two main causes for equipment unavailability: first, random equipment failures or other unforeseen factors (such as human error) leading to random equipment unavailability; and second, planned unavailability due to scheduled testing or maintenance work. Therefore, if nuclear power plant equipment is unavailable, its configuration status—whether planned or random—can be determined based on the cause of the unavailability.

[0028] It should be noted that if the configuration status of nuclear power plant equipment is "available," the risk monitoring system only affects specific system configurations, such as switching between operating and standby columns. If the configuration status of nuclear power plant equipment is "unavailable," it directly affects the configuration of the PSA model in the background of the risk monitoring system, and the unit's quantitative risk indicators change accordingly. Therefore, for unavailable statuses, it is possible to further determine whether the unavailability is planned or random.

[0029] S300: Based on the configuration status type of nuclear power plant equipment, retrieve configuration status data from multiple data sources. These multiple data sources include the nuclear power plant real-time database system, the nuclear power plant operation log system, the nuclear power plant work order management system, the work order isolation system, and a mapping table between nuclear power plant pre-maintenance items and unavailable equipment.

[0030] Specifically, if the configuration status type of the nuclear power plant equipment is "available," the configuration status data for the equipment in the "available" state can be retrieved from multiple data sources. If the configuration status type of the nuclear power plant equipment is "planned unavailable," the configuration status data for the equipment in the "planned unavailable" state can be retrieved from multiple data sources. If the configuration status type of the nuclear power plant equipment is "randomly unavailable," the configuration status data for the equipment in the "randomly unavailable" state can be retrieved from multiple data sources.

[0031] According to the technical solution provided in this application, by specifically distinguishing between planned unavailability and random unavailability when determining the configuration status type of nuclear power plant equipment, the classification of unavailability configuration status in the risk monitoring system is accurately sorted out. This allows the acquired configuration status data of nuclear power plant equipment to distinguish between the random and planned differences in unavailability, completely determining the corresponding equipment configuration status type in the nuclear power plant equipment configuration risk calculation. This improves the completeness and accuracy of the acquired configuration status data of nuclear power plant equipment and provides accurate equipment configuration status data input for the nuclear power plant risk monitoring system. Furthermore, this application embodiment can achieve automatic acquisition and determination of equipment configuration status data based on multiple data sources in nuclear power plant configuration risk assessment, providing accurate equipment configuration status data input to the nuclear power plant risk monitoring system quickly and automatically, thereby accurately completing the nuclear power plant configuration risk assessment.

[0032] Figure 2 The diagram shown is a flowchart illustrating a method for acquiring nuclear power plant equipment configuration status data according to another embodiment of this application. Figure 2 The embodiment shown is Figure 1 A variation of the illustrated embodiment. For example... Figure 2 As shown, with Figure 1 The difference in the illustrated embodiment is that step S310 is... Figure 1 A specific implementation of step S300 in the illustrated embodiment.

[0033] S310: If the configuration status type of the nuclear power plant equipment is available, then select the nuclear power plant real-time database system as the data source from multiple data sources, and obtain the configuration status data of the nuclear power plant equipment from the nuclear power plant real-time database system.

[0034] According to the technical solution provided in the embodiments of this application, if the configuration status type of nuclear power plant equipment is available, the nuclear power plant real-time database system is selected as the data source from multiple data sources. This allows the association between the equipment operation / open / push-in feedback, shutdown / close / disconnect feedback data points in the nuclear power plant real-time database system and the equipment configuration status, thereby enabling the acquisition of nuclear power plant equipment configuration status data from the nuclear power plant real-time database system.

[0035] In at least one embodiment of this application, step S320 is Figure 1 Another specific implementation of step S300 in the illustrated embodiment.

[0036] S320: If the configuration status type of the nuclear power plant equipment is planned unavailable, then select the nuclear power plant work order management system and work order isolation system as data sources from multiple data sources, and obtain the configuration status data of the nuclear power plant equipment from the nuclear power plant work order management system and work order isolation system.

[0037] For example, in the risk monitoring system's operating module, for equipment configuration status determined to be in a planned unavailable state, the nuclear power plant work order management system and work order isolation system can be selected as data sources to automatically obtain the configuration status data of nuclear power plant equipment from the nuclear power plant work order management system and work order isolation system.

[0038] In at least one embodiment of this application, steps S330 to S370 are Figure 1 Another specific implementation of step S300 in the illustrated embodiment.

[0039] S330: If the configuration status type of nuclear power plant equipment is random unavailable, then determine whether the real-time database system of the nuclear power plant includes equipment fault feedback data points.

[0040] S340: If the real-time database system of the nuclear power plant includes equipment fault feedback data points, then the real-time database system of the nuclear power plant shall be selected as the data source, and the configuration status data of the nuclear power plant equipment shall be obtained from the real-time database system of the nuclear power plant.

[0041] Specifically, for situations determined to be in a random unavailable state, if the nuclear power plant's real-time database system includes equipment fault feedback data points, the nuclear power plant's real-time database system can be selected as the data source. Setting the equipment fault feedback data points in the nuclear power plant's real-time database system can initially achieve the automatic acquisition of the configuration status data of nuclear power plant equipment.

[0042] S350: If the real-time database system of the nuclear power plant does not include equipment fault feedback data points, then determine whether the nuclear power plant operation log system includes unavailability information of nuclear power plant equipment.

[0043] S360: If the nuclear power plant operation log system includes unavailable information of nuclear power plant equipment, then the nuclear power plant operation log system is selected as the data source, and the configuration status data of the nuclear power plant equipment is obtained from the nuclear power plant operation log system.

[0044] Specifically, if the real-time database system of a nuclear power plant does not contain equipment fault feedback data points, but the nuclear power plant operation log system contains information on the unavailability of nuclear power plant equipment, then the nuclear power plant operation log system can be selected as the data source. By reading the information on unavailable equipment that triggers the relevant clauses of the nuclear power plant's technical specifications in the nuclear power plant operation log system, the equipment configuration status data can be automatically obtained.

[0045] S370: If the nuclear power plant operation log system does not include unavailable information of nuclear power plant equipment, then the nuclear power plant work order management system shall be selected as the data source, and the configuration status data of nuclear power plant equipment shall be obtained from the nuclear power plant work order management system.

[0046] Specifically, if the real-time database system of a nuclear power plant does not contain equipment fault feedback data points, and the nuclear power plant operation log system does not include information on the unavailability of nuclear power plant equipment, then the nuclear power plant work order management system can be selected as the data source. By reading the relevant information on the maintenance work orders for unavailable equipment in the nuclear power plant work order management system, the automatic acquisition of equipment configuration status data can be achieved.

[0047] Careful analysis revealed that if nuclear power plant equipment becomes unavailable due to corrective maintenance (fault repair), there is a risk that redundant equipment may be affected by the same fault, increasing the probability of common-cause failure and directly raising the overall risk level of the unit. However, if equipment becomes unavailable due to preventative maintenance, it does not affect the unit's risk level. The configuration risk analysis results for nuclear power units under these two different equipment unavailability configurations are drastically different.

[0048] Figure 3 The diagram shown is a flowchart illustrating a method for acquiring nuclear power plant equipment configuration status data according to another embodiment of this application. Figure 3 The embodiment shown is Figure 1 A variation of the illustrated embodiment. For example... Figure 3 As shown, with Figure 1 The difference in the illustrated embodiment is that step S200 is followed by step S250, and step S380 is... Figure 1 A specific implementation of step S300 in the illustrated embodiment.

[0049] S250: If the configuration status type of nuclear power plant equipment is planned unavailable, determine the work task category that caused the nuclear power plant equipment to be in a planned unavailable state. Work task categories include corrective maintenance, preventive maintenance, and periodic testing.

[0050] S380: Based on the configuration status type of nuclear power plant equipment, retrieve the configuration status data of nuclear power plant equipment from the nuclear power plant work order management system, work order isolation system, and mapping relationship data table.

[0051] According to the technical solution provided in the embodiments of this application, by classifying the planned unavailability configuration status of equipment into corrective maintenance, preventive maintenance, and periodic testing based on the work task categories, the acquired configuration status data of nuclear power plant equipment can further distinguish the differences in the work task categories that cause the planned unavailability of equipment under the planned unavailability status. This allows the risk indicator analysis results to reflect the risk differences caused by different work task categories, further improving the completeness and accuracy of the acquired configuration status data of nuclear power plant equipment, as well as the accuracy of the results of nuclear power plant equipment configuration risk analysis and the overall quality of configuration risk assessment.

[0052] In at least one embodiment of this application, step S250 includes: if the nuclear power plant has planned work orders with work order isolation instructions, the target work order entry is located in the work order management system by the work order isolation number, and the work task type information in the target work order entry is read to determine the category of the work task that causes the nuclear power plant equipment to be in a planned unavailable state; if the nuclear power plant does not have planned work orders with work order isolation instructions, such as running periodic tests, a mapping relationship data table between nuclear power plant pre-maintenance entries and unavailable equipment is determined, and the category of the work task that causes the nuclear power plant equipment to be in a planned unavailable state is determined by the unique pre-maintenance code in the mapping relationship data table. Thus, in the case of planned work orders with work order isolation instructions at the nuclear power plant, the category of the work task that causes the nuclear power plant equipment to be in a planned unavailable state is determined by reading the work order task type information in the target work order entry, thereby automatically determining the specific unavailability type of equipment, such as corrective maintenance, preventive maintenance, and periodic tests. In the case of planned work orders in nuclear power plants without work order isolation instructions, the specific unavailability types of equipment, such as preventive maintenance and periodic testing, can be automatically determined by using pre-maintenance codes with uniqueness in the work order entry and mapping relationship data table.

[0053] For example, in the planning module of the risk monitoring system, the scope of unavailable equipment is initially determined by reading the main equipment corresponding to the work order entry and the equipment information in the work order isolation instruction associated with the work order entry that is in a listed state. Secondly, for planned work orders of nuclear power plants without work order isolation instructions, based on a complete review of the mapping relationship data table between nuclear power plant pre-maintenance projects and unavailable equipment (for example, the data table style of XX nuclear power plant is shown in Table 1), the scope of unavailable equipment corresponding to the planned work order is determined by the unique pre-maintenance code of the work order entry and the mapping relationship data table. Finally, the specific unavailable types such as preventive maintenance and periodic testing of equipment are automatically determined by reading the pre-maintenance category information in the data table.

[0059] In the apparatus 100 provided in at least one embodiment of this application, the acquisition module 120 is further configured to select the nuclear power plant real-time database system as the data source from multiple data sources if the configuration status type of the nuclear power plant equipment is available, and acquire the configuration status data of the nuclear power plant equipment from the nuclear power plant real-time database system.

[0061] In the apparatus 100 provided in at least one embodiment of this application, the determination module 110 is further configured to determine whether the nuclear power plant real-time database system includes equipment fault feedback data points if the configuration status type of the nuclear power plant equipment is a random unavailable state; and to determine whether the nuclear power plant operation log system includes unavailable information of the nuclear power plant equipment if the nuclear power plant real-time database system does not include equipment fault feedback data points. The acquisition module 120 is further configured to select the nuclear power plant real-time database system as the data source and acquire the configuration status data of the nuclear power plant equipment from the nuclear power plant real-time database system if the nuclear power plant real-time database system includes equipment fault feedback data points; to select the nuclear power plant operation log system as the data source and acquire the configuration status data of the nuclear power plant equipment from the nuclear power plant operation log system if the nuclear power plant operation log system includes unavailable information of the nuclear power plant equipment; and to select the nuclear power plant work order management system as the data source and acquire the configuration status data of the nuclear power plant equipment from the nuclear power plant work order management system if the nuclear power plant operation log system does not include unavailable information of the nuclear power plant equipment.

[0062] It should be noted that the device 100 is the device corresponding to the method for obtaining nuclear power plant equipment configuration status data provided in the above-described embodiments of this application.

[0065] S500: Utilize configuration status data of nuclear power plant equipment to conduct configuration risk analysis of nuclear power plant equipment.

[0066] Specifically, if the configuration status of nuclear power plant equipment is in an available state, the operation module of the nuclear power plant risk monitoring system can perform real-time risk monitoring based on the acquired configuration status data of the nuclear power plant equipment in the available state. If the configuration status of nuclear power plant equipment is in a planned unavailable state, both the operation module and the planning module of the nuclear power plant risk monitoring system can perform planned risk prediction based on the acquired configuration status data of nuclear power plant equipment in the planned available state (e.g., equipment configuration status data generated by planned maintenance work of the nuclear power plant). The corresponding quantitative risk index calculation results can provide scientific and effective support for unit operation and maintenance decisions. If the configuration status of nuclear power plant equipment is in a random unavailable state, the operation module of the nuclear power plant risk monitoring system can perform real-time risk monitoring based on the acquired configuration status data of nuclear power plant equipment in the random unavailable state.

[0067] According to the technical solution provided in the embodiments of this application, by receiving the configuration status data of nuclear power plant equipment obtained in the above embodiments of this application, the risk monitoring system can update the configuration of the background PSA model so that the PSA model fully reflects the actual configuration status of nuclear power plant equipment, thereby accurately calculating quantitative risk indicators and evaluating the configuration risk level of nuclear power plant equipment, thereby improving the accuracy of the results of nuclear power plant equipment configuration risk analysis and the overall quality of configuration risk assessment.
