The main functions of the above documents or systems are as follows:

[0003] The in-service inspection outline is a programmatic document for in-service inspection of nuclear power plants, which is used to guide the preparation of the in-service inspection plan outline for each unit.

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] In order to solve the problems existing in the prior art, the present invention provides a method and system for managing an in-service inspection plan for a nuclear power plant. The method and system achieve unified storage and efficient call of data by establishing a centralized and standardized basic database of in-service inspection items, thereby ensuring the accuracy and consistency of data. The automated planning function is used to improve the efficiency and accuracy of the plan outline planning. At the same time, through the management of sampling inspection, a multi-channel flexible sampling method and a scientific sampling model are provided. At the same time, efficient and accurate work order maintenance and annual plan formulation can be achieved. It has the function of automatically generating an annual plan with one key, and also supports manual custom adjustment, meeting the actual needs of in-service inspection plan management for nuclear power plants and improving the safety and operational efficiency of nuclear power plants.

[0060] refer to Figure 1 , Figure 1 A schematic flow chart of the in-service inspection plan management method for a nuclear power plant provided by the present invention.

[0061] Specifically, Figure 1 As shown, the in-service inspection program management method for nuclear power plants includes the following steps:

[0062] Step S101: Obtain basic information of in-service inspection items of a nuclear power plant, and construct a basic database of in-service inspection items based on the basic information.

[0063] Optionally, in the embodiment of the present invention, the basic data includes, but is not limited to: the name of the inspected equipment, the model of the inspected equipment, the design and operation parameters of the inspected equipment, the inspected part, the inspection method, the inspection cycle, the planned zero point, the inspection item number, the inspection item description (i.e., the inspection item content description), the functional location, the maintenance plan number, the ten-year inspection plan and other detailed information. Among them, the planned zero point is the inspection plan zero point, that is, the time point when the first maintenance is performed in each inspection cycle. For example, there are three overhaul rounds in a year, and the first overhaul is on January 1, then this time point is the planned zero point.

[0064] Specifically, by collecting, organizing and summarizing the basic information of in-service inspection projects of nuclear power plants and forming a basic database, centralized and unified management of data is achieved, ensuring the accuracy and consistency of data.

[0065] Among them, the basic data can be entered into the system through the data entry interface of the computer terminal. The data entry interface can be divided into equipment information entry area, part information entry area, inspection method entry area, inspection cycle entry area and planned zero point entry area, etc., and each area corresponds to the relevant fields. It should be noted that the entry, addition, modification, deletion and other operations of basic data require approval, that is, the user enters the relevant information in the corresponding area and submits it for approval. After approval, the database is stored and a unique ID is configured. At the same time, the change history (such as time, personnel, content, etc.) is also recorded. Among them, for data that fails the review, the system automatically sends a review failure message to the user and explains the reason for the review failure. The user modifies the data according to the reason for failure and resubmits it. For data that fails the review three times, the data entry authority is locked and the information is reported to the relevant management personnel.

[0066] Step S102: Generate an in-service inspection plan outline based on the basic data in the basic database and the sampling quantity.

[0067] In an embodiment of the present invention, generating an in-service inspection plan outline based on basic data and sampling quantity in a basic database includes: calculating according to the plan zero point and the inspection cycle to obtain the inspection plan schedule; determining the sampling method and the sampling ratio; calculating according to the sampling method and the sampling ratio to obtain the sampling quantity; generating an in-service inspection plan outline based on the inspection plan schedule and the historical inspection records of the sampling quantity.

[0068] In the embodiment of the present invention, in order to be compatible with different requirements, a plan outline project field library can be set so that corresponding fields can be selected as needed to form the plan outline project content. For example, select the fields: serial number + inspected component + quantity + cycle + inspection method + approach method + inspection plan... Then, according to the selected fields, the plan outline is automatically generated by calling the basic data in the basic database.

[0069] like Figure 2 As shown, according to the inspection plan zero point, historical inspection records and sampling quantity, the inspection plan is set according to the inspection cycle. Among them, the inspection plan uses the overhaul cycle (cycle) or year as the unit to display the specific plan arrangement of the inspection items.

[0070] Furthermore, in an embodiment of the present invention, the nuclear power plant in-service inspection plan management method also includes: adjusting the in-service inspection plan outline according to the adjustment information; determining whether the in-service inspection plan outline meets the standard outline requirements of the nuclear power plant; if so, outputting the in-service inspection plan outline; if not, continuing to adjust the in-service inspection plan outline until it meets the standard outline requirements.

[0071] Specifically, when equipment fails or plans change, users can manually adjust the plan outline. Those with experience and relevant qualifications have the authority to make adjustments. They will periodically check the adjusted inspection plan to ensure that it complies with the requirements of the nuclear power plant's standard outline. At the same time, the system automatically records the operator, time, reason, and adjusted content.

[0072] In the embodiment of the present invention, the sampling methods include: random sampling, stratified sampling, rotation sampling and other methods. Among them, different sampling methods are applicable to different scenarios. For example, random sampling is used for samples with uniform overall and no stratified characteristics; stratified sampling is applicable to samples with stratified characteristics (such as device type, device level, etc.); rotation sampling is applicable to situations where the sample is limited and it is necessary to ensure that each data is drawn. Random sampling uses a random function to generate results, and rotation sampling arranges the next object according to the previous situation to ensure that each sample has a chance to be drawn.

[0073] Step S103: Generate an inspection project work order based on the in-service inspection plan outline and basic data in the basic database.

[0074] In an embodiment of the present invention, generating an inspection project work order based on the in-service inspection plan outline and basic data in a basic database includes: obtaining the inspection project number, inspection item description, functional location, maintenance plan number, inspection cycle and ten-year inspection plan; obtaining the inspection plan schedule based on the in-service inspection plan; generating an inspection project work order according to the inspection project number, inspection item description, functional location, maintenance plan number, inspection cycle, ten-year inspection plan and inspection plan schedule.

[0075] Step S104: Generate an annual plan based on the inspection project work order and the in-service inspection plan outline.

[0076] Generating an annual plan based on the inspection project work order and the in-service inspection plan outline includes: determining the overhaul cycle for the overhaul work order to be generated; screening the inspection project work orders according to the overhaul cycle of the overhaul work order to obtain the inspection project work orders corresponding to the overhaul cycle; screening the in-service inspection plan outline according to the overhaul cycle to obtain the inspection item list corresponding to the overhaul cycle; summarizing the inspection project work orders corresponding to the overhaul cycle and the inspection item list corresponding to the overhaul cycle to generate an annual plan.

[0077] Step S105: Implement in-service inspection based on the annual plan and obtain implementation feedback information.

[0078] Step S106: Generate a change adjustment plan based on the implementation feedback information.

[0079] Step S107: Update the in-service inspection plan outline according to the change adjustment plan.

[0080] like Figure 2As shown, after the annual plan is generated, it can be implemented based on the annual plan, and the implementation status can be collected and feedback can be provided based on the implementation status, so as to adjust and update the in-service inspection plan outline and realize automatic updating of the in-service inspection plan outline.

[0081] refer to Figure 3 , Figure 3 This is a principle block diagram of the nuclear power plant in-service inspection plan management system provided by the present invention. The nuclear power plant in-service inspection plan management system can be used to implement the nuclear power plant in-service inspection plan management method disclosed in the embodiment of the present invention.

[0082] Specifically, Figure 3 As shown, the nuclear power plant in-service inspection plan management system includes: a basic data management module 301, a project work order management module 303, a plan outline management module 302, an annual plan management module 304 and a plan outline adjustment module.

[0083] In the embodiment of the present invention, the basic data management module 301 is used to obtain basic information of in-service inspection items of a nuclear power plant, and to construct a basic database of in-service inspection items based on the basic information.

[0084] Specifically, the basic data management module 301 is used to centrally manage the basic information of in-service inspection items, mainly storing detailed information such as the name of the inspected equipment, the model of the inspected equipment, the design and operation parameters of the inspected equipment, the inspected part, the inspection method, the inspection cycle, the planned zero point, the inspection item number, the inspection item description, the functional location, the maintenance plan number, and the ten-year inspection plan. At the same time, the basic data management module 301 also sets a data review mechanism, as described above.

[0085] In an embodiment of the present invention, the plan outline management module 302 is used to generate an in-service inspection plan outline based on basic data and sampling quantity in a basic database, generate a change adjustment plan based on implementation feedback information, and update the in-service inspection plan outline according to the change adjustment plan.

[0086] In an embodiment of the present invention, the plan outline management module 302 includes: a plan automatic arrangement module, a sampling inspection submodule and a plan outline generation module; the sampling inspection submodule is used to calculate according to the determined sampling method and sampling ratio to obtain the sampling quantity; the plan automatic arrangement module is used to generate a change adjustment plan according to the implementation feedback information; the plan outline generation module is used to generate an in-service inspection plan outline according to the basic data and the sampling quantity, and update the in-service inspection plan outline according to the change adjustment plan.

[0087] In an embodiment of the present invention, the plan outline adjustment module is used to: adjust the in-service inspection plan outline according to the adjustment information; determine whether the in-service inspection plan outline meets the standard outline requirements of the nuclear power plant; if so, output the in-service inspection plan outline; if not, continue to adjust the in-service inspection plan outline until it meets the standard outline requirements.

[0088] In the embodiment of the present invention, the project work order management module 303 is used to generate an inspection project work order based on the in-service inspection plan outline and basic data in the basic database.

[0089] Specifically, the project work order management module 303 is provided with a data entry and maintenance entry, which is used to store the inspection project work order list, including basic elements such as: maintenance plan number, inspection project number, functional location, inspection project description, inspection cycle, inspection plan within the past ten years (i.e., ten-year inspection plan), etc. Among them, one inspection project work order corresponds to one maintenance plan number, and may correspond to multiple inspection project numbers, that is, one inspection project work order may be composed of multiple inspection project numbers with the same implementation conditions, and is summarized into one inspection project work order through a project description (also called an inspection project description or an inspection project content description) for the convenience of on-site management. Figure 4 As shown in the figure, from the two projects with the same inspection conditions in the plan outline, the project content description is summarized and merged into an inspection project work order. Among them, when the project cannot be executed according to the work order, the information needs to be reported.

[0090] In the embodiment of the present invention, the annual plan management module 304 is used to generate an annual plan according to the inspection project work order and the in-service inspection plan outline, and to feed back the implementation feedback information to the plan outline management module 302.

[0091] The annual plan management module 304 integrates the overhaul work order and the inspection item detail table.

[0092] Optionally, in an embodiment of the present invention, the annual plan management module 304 includes: an overhaul work order generation module and an inspection item detailed table generation module. The overhaul work order generation module is used to call the inspection project work order in the project work order management module 303 according to the selected overhaul round to filter out the corresponding inspection project work order and generate an overhaul work order in summary. The inspection item detailed table generation module is used to call the in-service inspection plan outline in the plan outline management module 302 according to the selected overhaul round to filter out the corresponding inspection item list and generate an inspection item detailed table in summary.

[0093] Specifically, when it is necessary to generate an annual plan for a certain overhaul, the user selects the overhaul cycle for the overhaul work order to be generated through the system interface. At this time, the annual plan management module 304 calls the inspection project work order in the project work order management module 303 according to the selected overhaul cycle, and then automatically identifies and selects the corresponding inspection project work order with a scheduling mark (such as plan) set in the inspection field under the overhaul cycle, and summarizes it into an overhaul work order. At the same time, according to the selected overhaul cycle, the in-service inspection plan outline in the plan outline management module 302 is called, and then the relevant inspection item list with a scheduling mark (such as plan) set in the inspection plan field under the overhaul cycle is automatically identified and selected, and the inspection item detailed table is summarized and generated. Finally, the overhaul work order and the inspection item detailed table are used as the basic content of the annual plan to generate the corresponding annual plan table.

[0094] In the embodiment of the present invention, the annual plan management module 304 also has a custom adjustment module, which can rearrange the inspection items, add or delete certain inspection items according to the actual conditions of the overhaul medium- and long-term planning adjustment, human and material resources, etc. When the annual plan is adjusted by custom adjustment, it is automatically checked whether the adjusted plan meets the inspection cycle requirements. If not, the system outputs a modification prompt, and the user makes corresponding modifications until it meets the requirements.

[0095] The following is a description of a specific embodiment.

[0096] Specifically, when a new inspected device needs to be entered, the user fills in the relevant information in the system interface, such as (1) the inspected part of the reactor pressure vessel is the nozzle weld, the inspection method is ultrasonic testing, the inspection cycle is T1 (nC, n = 123 ..., C = cycle, representing a cycle), and the planned zero point is C0. (2) The inspected parts of a group of containers (m units) are the inside and outside, the inspection method is sampling visual inspection, the inspection cycle is T2 (cycle), and the planned zero point is C0.

[0097] After the data entry is completed, it is submitted to the approval personnel. After approval, the data is stored in the database, and a unique ID is assigned to the reactor pressure vessel nozzle weld ultrasonic inspection project, such as "RPV001"; a unique ID is assigned to the container visual inspection project, such as TANK001, TANK002...TANK00n.

[0098] The system calls the basic data in the basic database. For example, for the reactor pressure vessel "RPV001", according to its inspection cycle (T = nC, C represents cycle, n is 1, 2, 3...) and the planned zero point (C0), it automatically calculates the yth cycle after x cycles T from the planned zero point C0. The calculation formula is as follows:

[0099]

[0100] For example, using formula (1), if the inspection cycle of RPV001 is T = 6C, the inspection after the first cycle T is scheduled at the 7th cycle, i.e., C7. The inspection after the second cycle T is scheduled at the 13th cycle, i.e., C 13 .

[0101] It should be noted that if due to special circumstances, such as changes in the equipment operating environment, early inspection is required, the user can manually adjust the inspection plan in advance and postpone it by i cycles (i = ±1, 2, 3...) as the (yi)th cycle. At the same time, the subsequent inspection plan will use the adjusted inspection plan as the plan zero point and will be synchronized and adjusted according to the cycle requirements.

[0102] In the sampling inspection, for containers TANK001, TANK002, ... TANK00n, according to their inspection cycle and planned zero point, the next inspection plan C is automatically calculated according to formula (1). y . Select the rotation sampling method, set the sampling ratio to m%, and the system automatically calculates the sampling inspection quantity N_tank = n*m%, conservative strategy, if the inspection quantity N_tank has decimals, the decimal places are only rounded up. Then the number of N_tank containers in the n containers sampled in the y cycle is N_tank. According to the rotation sampling method, the system automatically arranges the containers that have not been sampled in the y cycle for the y+y cycle. If the remaining number of unsampled containers in the y cycle does not meet the sampling quantity requirements, the containers that have been sampled in the y cycle are taken for repeated inspection, and so on.

[0103] Based on the data in the plan outline management module 302, the project work order management module 303 integrates one or more inspection project numbers with the same implementation conditions into one inspection project work order (such as integrating the 1.1.1 and 1.1.2 items with the same inspection methods and inspection cycles) into an inspection project work order with the maintenance plan number 8001. The maintenance plan number is unique. Figure 4 As shown in the figure, each project work (also called inspection project work order) includes: maintenance plan number, inspection project number, functional location, project content description, inspection cycle, inspection plan for the past ten years, etc. For example, ultrasonic testing is performed in the xth cycle, and the required testing equipment, personnel qualification requirements, estimated working hours, etc. are listed in detail. For containers TANK001, TANK002...TANK00n, the whole is regarded as an inspection project work order with a unique maintenance plan number of 80002. The project content description should include the complete inspection parts of TANK001, TANK002...TANK00n.

[0104] When it is necessary to prepare the annual overhaul plan for the xth cycle, the projects marked with inspection plans in the xth cycle in the plan outline management module 302 and the project work order management module 303 are integrated and summarized into an overhaul work order list and an inspection item detail table to generate an annual plan. The annual plan can intuitively display the inspection content of the current cycle and can be adjusted and optimized if necessary. The adjusted plan is submitted to the approval process to ensure the standardization and traceability of the approval through electronic signatures, approval records, etc. After approval, the system automatically publishes the official annual overhaul plan and notifies relevant personnel to execute it through emails, text messages, etc.

[0105] When the annual overhaul plan for the xth cycle is completed, each inspection item item is marked with "finish", indicating that the inspection has been completed, and the associated keys in the plan outline management module 302 and the project work order management module 303 trigger the synchronization of data, and automatically complete the update of the inspection plan status.

[0106] Through the above specific implementation examples, it can be clearly seen that the practical application and effect of the present invention in the management of in-service inspection plans of nuclear power plants can achieve efficient, accurate and flexible management.

[0107] The present invention can achieve the following effects:

[0108] Improve management efficiency: Through automated processes and data integration, the management efficiency of the in-service inspection program is significantly improved, reducing manual operation errors and omissions.

[0109] Enhanced plan relevance: A close relationship is achieved between the unit plan outline, inspection project work order, and overhaul annual plan, ensuring the consistency and accuracy of plan information.

[0111] Automatically generate annual plan: Automatically generate annual plan draft with one click, support manual custom adjustment to meet actual needs, improve efficiency and adaptability.

[0112] Realize dynamic update: The system can automatically update the status of relevant plans according to the execution of the annual overhaul plan, providing strong support for the formulation and adjustment of subsequent plans.

[0113] Specifically, the specific coordination operation process between the units in the nuclear power plant in-service inspection plan management system here can refer to the above-mentioned nuclear power plant in-service inspection plan management method, which will not be repeated here.

[0114] In addition, an electronic device of the present invention includes a memory and a processor; the memory is used to store a computer program; the processor is used to execute the computer program to implement any of the above methods for managing in-service inspection plans for nuclear power plants. Specifically, according to an embodiment of the present invention, the process described with reference to the flowchart above can be implemented as a computer software program.
