Description

Technical Field

[0001] The present invention relates to the technical field of in-service inspection of nuclear power plants, and more specifically to a method, system, storage medium and electronic equipment for managing overdue verification of in-service inspection of nuclear power plants. Background Art

[0002] Generally, after a nuclear power plant has been in operation for a period of time, it will be shut down for nuclear fuel replacement according to a plan. During this period, the nuclear power plant will arrange large-scale maintenance activities, namely, overhaul. The in-service inspection items carried out during the overhaul are the overhaul in-service inspection items. The in-service inspection of some equipment or systems needs to be carried out during non-overhaul periods, which are routine in-service inspection items.

[0003] For projects that are inspected regularly, the fixed interval of the inspection is the cycle, which is usually measured in the number of overhaul rounds (for overhaul projects) or calendar years (for routine projects). For example, the ultrasonic inspection cycle of the container weld of a certain overhaul project is 6C. If the previous inspection was carried out in C01, then the next overhaul should be arranged at C01+6C, that is, C07; or, for example, the pipeline thickness inspection cycle of a certain routine project is 2 years. If the previous inspection was carried out in X year, then the next routine inspection should be arranged in X+2 years. Among them, in-service inspections are divided into different categories such as complete in-service inspections, partial in-service inspections, and other in-service inspections. The in-service inspection cycles of different categories are also different. In-service inspection items in conventional islands are divided into regular inspections and annual inspection items. The regular inspection project cycle usually exceeds 1C, and the annual inspection project is usually 1C or 1 year. The inspection content of the regular inspection project usually covers the annual inspection project.

[0004] Due to the complex association between in-service inspection categories and cycles and the large number of cycle margin types, the in-service inspection overdue verification management generally relies on in-service inspection engineers to manually check whether there are any overdue issues in the scheduling of in-service inspection plan documents and whether there are any overdue issues in the actual project intervals. Although manual verification is relatively flexible, it may fail to discover the overdue issues in the in-service inspection plan management in a timely manner due to human errors. Summary of the invention

[0053] 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.

[0054] The present invention provides a method for verifying and managing in-service inspection overdue of a nuclear power plant. The method can quantify the cycle and margin of different types of in-service inspection items, and can realize batch automatic calculation of whether the prepared in-service inspection plan management schedule has overdue conditions. In addition, it can also batch automatic calculation of whether the inspection and overhaul rounds required to be specified have overdue conditions. It can quickly assist in-service inspection plan engineers to lock in items that may be overdue, and can save a lot of time and energy for in-service inspection plan engineers.

[0055] Specifically, overdue verification management refers to the management of whether the planned scheduling of a certain inspection project exceeds the cycle requirements of the upstream in-service inspection outline document for the project, or whether the actual interval of the in-service inspection exceeds the cycle requirements of the upstream sub-in-service inspection outline document for the project.

[0056] The positive margin of cycle refers to the time that can be allowed to exceed the specified in-service inspection cycle. For example, if the cycle of an inspection project is 5 years and its positive margin of cycle is 2 years, then the maximum cycle of the project is 5+2 years, that is, the maximum cycle is 7 years.

[0057] Negative cycle margin refers to the time that can be allowed to be inspected in advance based on the specified in-service inspection cycle. For example, if the cycle of an inspection item is 3C and its negative cycle margin is 1C, then the shortest cycle of the item is 3-1C, that is, the longest cycle is 2C.

[0058] Specifically, refer to Figure 1 , Figure 1 It is a flow chart of a preferred embodiment of a method for managing overdue verification of in-service inspection of a nuclear power plant provided by the present invention.

[0059] Specifically, Figure 1 As shown, the in-service inspection overdue verification management method for nuclear power plants includes the following steps:

[0060] Step S101: construct an in-service inspection item table.

[0061] In some embodiments, constructing an in-service inspection item list includes: obtaining inspection item elements based on the in-service inspection outline of the nuclear power plant; establishing an in-service inspection item list based on the inspection item elements; and the in-service inspection item list is an independent in-service inspection item list.

[0062] Specifically, first, according to the in-service inspection outline of nuclear power plants, an independent inspection item list is established. Independence means that if there is only one difference in the inspection item elements, it needs to be split into different items and assigned different item numbers. In addition, independent scheduling is also performed during planning management scheduling.

[0063] Among them, the inspection project elements include: inspected part, reference drawing number, functional position code or pipeline number, inspection quantity or scope, inspection method, approach method, in-service inspection cycle, etc. Among them, the project number refers to the number of each inspection item, that is, the ID number of the project item, which is the only keyword to distinguish different inspection items. The overhaul project starts with O and the daily project starts with N. The inspected part refers to the inspected part of the inspected object. The reference drawing number refers to the reference drawing number of the "In-Service Inspection Outline" for the corresponding project. The pipeline weld or support items use isometric drawings, and the inapplicable items are indicated by NA. The functional position code or pipeline number refers to the equipment using the equipment functional position code, the pipeline weld or support items use the main pipeline loop number or system pipeline number, and the inapplicable items are indicated by NA. The inspection quantity or scope refers to the inspection quantity or inspection scope of the specific inspected object. The inspection method refers to the code of the non-destructive testing method used for the inspection item. The approach method refers to the approach method describing the inspection item, generally described as inside or outside. The in-service inspection cycle category refers to the description of the in-service inspection cycle, such as complete in-service inspection, partial in-service inspection, other in-service inspection, every ten years, every refueling overhaul, etc. The planning schedule refers to the overhaul project inspection plan marked in the field "CXX" (X is an Arabic numeral): such as C01 means the 01st refueling overhaul. The routine project inspection plan is a specific calendar year.

[0064] Step S102: After the construction of the inspection item table is completed, plan management and scheduling are performed according to the in-service inspection cycle to determine the inspection plan for the inspection items in the inspection item table.

[0065] In some embodiments, planning management and scheduling are performed according to the in-service inspection cycle, and the inspection plan for the inspection items in the inspection item table is determined, including: formulating a corresponding inspection plan according to the in-service inspection cycle of each inspection item; and filling in a corresponding category label in the corresponding inspection item table according to the inspection category based on the inspection plan.

[0066] Specifically, after the establishment of the inspection item table, it is necessary to formulate an inspection plan in the planning and scheduling field according to the in-service inspection cycle of the corresponding project. For example, which rounds of overhaul plan inspection or which planned inspections, after determining the overhaul rounds or calendar years for inspection, fill in the corresponding category label in the corresponding inspection item table according to the inspection category, such as P, S, D, etc. For example, a certain in-service inspection item was originally planned to be executed during the C05 overhaul, that is, the original inspection item table item needs to fill in P in the C05 planning and scheduling table. For example, a certain in-service inspection item was originally planned to be executed conditionally in 2035, that is, the original inspection item table item needs to fill in S in the 2035 planning and scheduling table. For example, a certain in-service inspection item was originally planned to be executed during the C06 overhaul, but there are other projects that may completely cover the scope of the project and are also planned to be executed during the C06 overhaul, then the inspection item table item needs to fill in D in the C06 planning and scheduling table. Among them, P means that a certain inspection item is subject to "planned inspection" in a certain overhaul cycle or daily calendar year; S means that a certain inspection item is subject to "conditional inspection" in a certain overhaul cycle or daily calendar year; D means that a certain inspection item has been included and covered by other items in a certain overhaul cycle or daily calendar year and is equivalent. Among them, planned inspection means that a certain item needs to be inspected according to the plan and the inspection will be carried out in the planned overhaul cycle or daily calendar year. Conditional inspection means that when a certain item reaches the planned overhaul cycle or daily calendar year, the trigger condition must be met before the inspection can be carried out. If the trigger condition is not met, the inspection will be cancelled.

[0067] Step S103: Acquire actual execution information of the in-service inspection items.

[0068] Specifically, the actual execution information of the in-service inspection items includes: completed or cancelled.

[0069] Step S104: Maintain and update the inspection plan according to the actual execution information.

[0070] In some embodiments, maintaining and updating the inspection plan according to the actual execution information includes: maintaining and updating the category tags of the inspection plan corresponding to the completed or cancelled inspection items.

[0071] Specifically, as the in-service inspection work progresses, some in-service inspection items will be completed as planned, while others may be cancelled for other reasons. Therefore, it is necessary to maintain and update the relevant schedules based on the inspection result information (i.e., actual execution information). For example, if an in-service inspection item was originally planned to be executed during the C05 overhaul and has been completed during the C05 overhaul, the P in the original C05 schedule table needs to be updated to PF; if it is cancelled during the C05 overhaul for some reason, the P in the original C05 schedule table needs to be updated to PC; SF, SC, DF, and DC are similar. Among them, PF means that a certain inspection item has been "completed the planned inspection" in a certain overhaul cycle or a normal calendar year; PC means that a certain inspection item has been "cancelled the planned inspection" in a certain overhaul cycle or a normal calendar year; SF means that a certain inspection item has been "completed the conditional inspection" in a certain overhaul cycle or a normal calendar year; SC means that a certain inspection item has been "cancelled the conditional inspection" in a certain overhaul cycle or a normal calendar year; DF means that a certain inspection item has been included and covered by other items in a certain overhaul cycle or a normal calendar year, and the corresponding covered items have been completed; DC means that a certain inspection item has been included and covered by other items in a certain overhaul cycle or a normal calendar year, and the corresponding covered items have been cancelled. F means that a certain inspection item has been "completed unplanned inspection" in a certain overhaul cycle or a normal calendar year.

[0072] Step S105: quantifying the in-service inspection cycle and margin of the inspection items in the in-service inspection item table for which the inspection plan maintenance and update has been completed.

[0073] In some embodiments, quantifying the in-service inspection cycle and margin of the inspection items in the in-service inspection item table that has completed the inspection plan maintenance and update includes: quantifying the in-service inspection cycle and margin of the inspection items in the in-service inspection item table that has completed the inspection plan maintenance and update according to the cycle category of the previous inspection period.

[0074] Specifically, in-service inspections use different upstream sub-specifications, and the cycle categories of inspection items will be different. Taking the overhaul project of the RSE-M specification of a nuclear power plant as an example, different in-service inspection cycles and cycle margins of different projects are specified using different descriptions, but without quantification, batch automatic calculation cannot be performed. Therefore, it is necessary to quantify the in-service inspection cycles and margins of different categories. The quantification table is shown in the following table.

[0075]

[0076]

[0077] Step S106: After completing the quantification of the in-service inspection cycle and margin, perform overdue verification calculation on the planned management schedule of the inspection project.

[0078] In some embodiments, performing overdue verification calculation on the planned management schedule of the inspection project includes: performing overdue calculation on the planned management schedule of the inspection project; and performing overdue non-execution calculation on the designated inspection and overhaul rounds.

[0079] Among them, the overdue calculation of the planned management schedule of the inspection project includes: calculating the actual scheduling cycles of the two inspection plans before and after the inspection project to be calculated; subtracting the prescribed cycle of the inspection project to be calculated from the actual scheduling cycle to obtain the prescribed schedule difference; and verifying whether it is overdue based on the prescribed schedule difference.

[0080] The calculation of overdue and unexecuted inspection and overhaul cycles for the specified inspection and overhaul cycles includes: obtaining the execution interval by taking the difference between the previous inspection plan and the specified inspection plan for the inspection item to be calculated; obtaining the specified execution difference by taking the difference between the specified cycle and the execution interval for the inspection item to be calculated; and verifying whether it is overdue based on the specified execution difference.

[0081] Specifically, the prescribed period refers to the in-service inspection period of the inspection item after quantification, that is, the in-service inspection period after quantification in step S105. The scheduling period is the absolute value of the difference between the two schedulings before and after quantification (taking the maximum value). The execution interval represents the absolute value of the difference between the last inspection overhaul or calendar year and the specified overhaul or calendar year.

[0082] Specifically, the overdue verification calculation of the planned management schedule of the inspection items includes two major modules. The first module is: batch automatic calculation of whether the planned management schedule of the in-service inspection items that have been compiled has overdue conditions. The specific calculation principle is: first calculate the actual scheduling cycle of the overhaul rounds or calendar year before and after the two planned inspections of a certain inspection item, and then subtract the actual scheduling cycle from the specified cycle of the inspection item obtained in step S105. The resulting value is the specified scheduling difference, which represents the difference between the specified cycle and the actual scheduling cycle. If the specified scheduling difference is within the positive and negative margin range, it means that there is no overdue, otherwise it is overdue. Then the other inspection items are calculated cyclically.

[0083] For example, for item 0339, the in-service inspection cycle category is described as "partial in-service inspection, one in-service inspection between two complete in-service inspections", and the specified cycle (unit: C) is 3 after quantification; its positive and negative margins are both 1, as shown in the following table:

[0084]

[0085]

[0086] The actual planned schedules for the front and rear sides are C01 and C05, where C01 is DF, which means that the project has been completed equivalently in the C01 overhaul; C05 is P, which means that the C05 overhaul plan is checked. After calculation, the actual planned schedules for the front and rear sides C01 and C05 have a cycle of 4, which is 4 in the schedule cycle (unit: C) table. Then, the actual schedule cycle 4 is subtracted from the specified cycle 3 of the project, and the value is -1, which is the specified schedule difference. Since the project has a positive margin of 1 (that is, compared with the specified cycle, the overhaul can be delayed by 1 round, and the actual schedule cycle can be 3+1=4,), it means that there is no overdue.

[0087] The second module is to automatically calculate in batches whether the inspection and overhaul rounds that need to be specified have been overdue. The specific calculation principle is: first calculate the difference between the last inspection and overhaul or calendar year of a certain inspection item and the specified overhaul or calendar year to obtain the execution interval, and then subtract the execution interval from the specified cycle of the item obtained in step 4 to obtain the value of the specification execution difference, which represents the difference between the specified cycle and the execution interval. If the specification execution difference is within the positive and negative margin range, it means that there is no overdue, otherwise it is overdue. Then loop calculations are performed on other inspection items. For example, for item number O339, if you want to specify whether the C04 round overhaul has been overdue, after calculation, the difference between the last inspection and overhaul C01 and C04 is 3, which is 3 in the execution interval (unit: C) table. Then subtract the execution interval 3 from the specified cycle 3 of the item to obtain a value of 0, which is the specification execution difference. If it is within the positive and negative margin range, it means that there is no overdue.

[0088] refer to Figure 7 The present invention also provides a nuclear power plant in-service inspection overdue verification management system. Specifically, Figure 7 As shown in the figure, the nuclear power plant in-service inspection overdue verification management system includes:

[0089] The project list construction unit 701 is used to construct an in-service inspection project list.

[0090] The inspection plan formulation unit 702 is used to perform plan management and scheduling according to the in-service inspection cycle after completing the construction of the inspection item table, and determine the inspection plan of the inspection items in the inspection item table.

[0091] The information acquisition unit 703 is used to acquire the actual execution information of the in-service inspection items.

[0092] The maintenance and updating unit 704 is used to maintain and update the inspection plan according to the actual execution information.

[0093] The quantification unit 705 is used to quantify the in-service inspection cycle and margin of the inspection items in the in-service inspection item table for which the inspection plan maintenance and update has been completed.

[0094] The overdue verification unit 706 is used to perform overdue verification calculation on the planned management schedule of the inspection project after completing the quantification of the in-service inspection cycle and margin.

[0095] Specifically, the specific coordination operation process between the various units in the in-service inspection overdue verification management system of the nuclear power plant here can refer to the above-mentioned in-service inspection overdue verification management method of the nuclear power plant, which will not be repeated here.

[0096] The following is a description of a specific embodiment.

[0097] Specifically, take the method and system for in-service inspection overdue verification management established in accordance with the RSE-M specification for a unit of a nuclear power plant as an example, as follows:

[0098] Step 1. Create an in-service inspection project data table

[0099] First, according to the in-service inspection outline of a nuclear power plant, a mutually independent inspection item list is established. Mutually independent means that as long as there is one difference in the following inspection item elements, it is necessary to split it into different projects, assign different project numbers, and then perform independent scheduling during planning management and scheduling. Screenshots of some projects are as follows: For example, although the elements of project numbers O9 and O10 such as the inspected parts, reference drawing numbers, functional locations or pipeline numbers, and inspection quantities or scopes are exactly the same, the inspection methods are different, so different project numbers need to be assigned independently. For example, Figure 2 shown.

[0100] Step 2. Schedule according to the in-service inspection cycle

[0101] After the inspection item table is established, you need to formulate an inspection plan in the planning and scheduling field according to the in-service inspection cycle of the corresponding project, that is, which rounds of overhaul are planned for inspection or which years are planned for inspection. After determining the overhaul rounds or calendar years for inspection, fill in the P, S, D and other codes according to the inspection category in the corresponding table; for example Figure 3 shown.

[0102] Step 3. Maintain the in-service inspection schedule based on completed or cancelled in-service inspection items

[0103] As the in-service inspection work progresses, some in-service inspection projects will be completed as planned, while others may be cancelled for other reasons; the in-service inspection plan engineer needs to maintain and update the relevant schedule based on the inspection results. For example, after the completion of step 2, for example, the inspection of the C01, C02 and C03 overhaul projects has been completed, and an update is required. Figure 4 The rectangular frame part is shown.

[0104] Step 4. Quantify in-service inspection cycles and margins

[0105] In-service inspections use different upstream specifications, and the cycle categories of inspection items will be different. Taking the overhaul project of the nuclear island RSE-M specification as an example, the in-service inspection cycle and cycle margin of different projects are specified using different descriptions. However, without quantification, computer batch automatic calculation cannot be performed, so it is necessary to quantify the project cycles of different categories. Figure 5 As shown in the rectangular box part.

[0106] Step 5. Batch overdue verification calculation

[0107] The first module: batch automatic calculation of whether the prepared in-service inspection plan management schedule has been overdue. The second module: batch automatic calculation of whether the specified inspection and overhaul rounds have been overdue. Figure 6 The rectangular frame part is shown.

[0108] 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 overdue verification of nuclear power plants.
