[0047] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0049] With global climate change and the increasing demand for energy from various countries, nuclear energy is gradually becoming a key force in the energy transition. Among them, graphite and carbon components can serve as important functional and structural materials for nuclear reactors. Due to their structure and properties, graphite and carbon components can withstand mechanical loads, thermal stress, radiation stress, and chemical corrosion for decades under high temperature and high radiation conditions, exhibiting good stability.

[0050] During the production of graphite and carbon components, especially in the calcination, molding, and graphitization processes, the characteristics of the raw materials themselves can lead to defects in the produced nuclear graphite, such as pores, cracks, and inclusions. These defects may extend to a critical point during the service life of the graphite and carbon components, causing them to crack and detach, thereby affecting reactor safety.

[0051] Therefore, to ensure the safety of nuclear reactors, before graphite and carbon components are installed in the reactor, surface inspection methods can be used to detect whether there are non-compliant defects on the surface of graphite and carbon components, and reactor component inspection systems, such as computed tomography (CT) imaging technology, can be used to screen for defects inside graphite and carbon components.

[0052] Understandably, the defect detection capability of the reactor component inspection system affects the safety of the nuclear reactor. Therefore, how to verify the ability of the reactor component inspection system to check for internal defects in graphite and carbon components is a technical problem that relevant technical personnel urgently need to solve.

[0053] To address the problems of the prior art, this application provides a performance verification method for a reactor component testing system and a reactor test piece 100. The performance verification method for the reactor component testing system provided in this application is described below.

[0054] It should be noted that the performance verification method for the reactor component testing system provided in this application requires the use of the reactor test piece 100 to verify the performance of the reactor component testing system. Therefore, the specific implementation of the reactor test piece 100 provided in this application is described below with reference to the accompanying drawings.

[0055] Figure 1 A schematic diagram of the architecture of a reactor test piece 100 provided in one embodiment of this application is shown. Figure 1 As shown, the reactor test piece 100 includes: a stage 110, which includes a cavity 111; a cover plate 120 for sealing the cavity 111; and a plurality of movable components 130 arranged in an array in the cavity 111. The movable components 130 include defective movable components 131 and non-destructive movable components 132, and each defective movable component 131 includes at least one defect.

[0056] For example, the central region of the shelf 110 is recessed to form a cavity 111 to accommodate a plurality of movable components 130, and the cavity 111 is closed by a cover plate 120.

[0057] The dimensions of the cavity 111 in the platform 110 can be determined based on the dimensions of the reactor components. In one example, the cross-sectional size of the cavity 111 can be greater than or equal to the largest cross-section in the reactor components.

[0058] For example, the material corresponding to the active component 130 can be a material used to build a reactor; for instance, the material of the active component 130 can be graphite and carbon. Furthermore, the dimensions of each active component 130 can be determined by relevant technical personnel according to different testing requirements.

[0059] The multiple active components 130 can be divided into defective active components 131 and non-destructive active components 132 according to the presence or absence of defects. The defective active components 131 can include defective active components 131 with different defect types, and the size of the defects can be different in each type of defective active component 131. The non-destructive active components 132 have no defects on their surface or internally.

[0060] The defective active component 131 can be created by using relevant drilling techniques within the non-destructive active component 132, based on the non-destructive active component 132. It is understood that creating the defective active component 131 based on the non-destructive active component 132 ensures that the defect in each defective active component 131 is unique and known, thereby guaranteeing the accuracy of the verification results during subsequent verification of the reactor component inspection system performance.

[0061] Furthermore, different types and sizes of defects can occur in graphite and carbon components during the manufacturing process. Those skilled in the art can construct defects in the defective active component 131 based on these defects. Specifically, those skilled in the art can determine the types and sizes of defects in the different defective active components 131.

[0062] In one example, Figure 2 A schematic diagram of a non-destructive active component 132 provided in one embodiment of this application is shown, as follows: Figure 2 As shown, the non-destructive active component 132 can be a cube, which can be used to fill the cavity 111 of the stage 110 to simulate a defect-free matrix in graphite and carbon components.

[0063] In another example, the defect activity component 131 may include a hole defect activity component 131, a crack defect activity component 131, and a chamfer activity component 130.

[0064] in, Figure 3 A schematic diagram of a hole defect active component 131 provided in one embodiment of this application is shown, as follows: Figure 3As shown, the hole defect active component 131 can be based on the non-destructive active component 132 with a cylindrical hole to simulate pore-like defects in graphite and carbon components. The diameter and depth of the hole can be preset by relevant technical personnel.

[0065] Figure 4 A schematic diagram of a crack defect active component 131 provided in one embodiment of this application is shown, as follows: Figure 4 As shown, the crack defect active component 131 can be based on the non-destructive active component 132 with a groove to simulate crack-like defects in graphite and carbon components. The size of the groove can be preset by relevant technicians.

[0066] Figure 5 A schematic diagram of a chamfering active component 130 provided in one embodiment of this application is shown, as follows: Figure 5 As shown, the chamfered movable component 130 can be made by rounding a chamfer on one edge of the non-destructive movable component 132. It is understood that, due to the limitations and errors in the manufacturing process, in order to ensure that the cavity 111 can be filled by multiple movable components 130, the size and shape of the movable components 130 need to be precisely controlled. Therefore, by setting a chamfer in the movable component 130, it can be ensured that multiple movable components 130 can completely fill the cavity 111.

[0067] In some alternative embodiments, the shelf 110 and the cover 120 can be connected by a plug-in joint, thereby making the connection between the two more stable and tighter, effectively preventing the multiple moving components 130 from sliding or falling off.

[0068] The reactor test piece 100 in this embodiment includes a platform 110, a cover plate 120, and multiple movable components 130. The multiple movable components 130 are arranged in an array within a cavity 111 and are sealed by the cover plate 120. Each movable component 130 includes defective movable components 131 and non-destructive movable components 132, and each defective movable component 131 includes at least one defect. Using such a reactor test piece for a reactor component inspection system can accurately reflect the system's ability to detect various defects in reactor components, thus enabling performance verification of the reactor component inspection system.

[0069] In order to facilitate the verification of various performance characteristics of the reactor component testing system, as another implementation of this application, another implementation of the reactor test piece 100 is also provided, as detailed in the following embodiments.

[0070] Figure 6 A schematic diagram of the architecture of a reactor test piece 100 provided in one embodiment of this application is shown. Figure 6As shown, the shelf 110 includes a base plate 112 and a frame 113, wherein the frame 113 is a preset base plate 112 to form a cavity 111; the base plate 112 is used to support the movable component 130.

[0071] For example, multiple active components 130 can be arrayed in a cavity 111 formed by a border 113.

[0072] For example, the frame 113 can be a detachable component. It is understood that different active components 130 can be used for testing different performance characteristics of the reactor component inspection system. The structures of different active components 130 can differ when combined. Therefore, to save resources, any combination of different active components 130 can be achieved by replacing the frame 113, thereby improving the versatility and interchangeability of components such as the base plate 112 and the cover plate 120, and thus reducing costs.

[0073] In one example, Figure 7 as well as Figure 8 Schematic diagrams of the frame 113 provided in one embodiment of this application are shown. When testing the spatial resolution of a reactor component detection system, it can be achieved through methods such as... Figure 7 The components shown are tested; when testing the density resolution of the reactor component detection system, it can be done through, as shown in the example... Figure 8 The components shown are tested.

[0074] In this embodiment of the application, by setting the border 113, it is possible to increase the versatility of each component and save costs while realizing various performance tests of the reactor component detection system.

[0075] To ensure that all components in the reactor test piece 100 can be tightly connected, as another implementation of this application, this application also provides another implementation of the reactor test piece 100, as detailed in the following embodiments.

[0076] In some alternative embodiments, the frame 113 is inserted and engaged with the base plate 112 and the cover plate 120 along the first direction to be positioned in the second direction and the third direction. The first direction, the second direction and the third direction are perpendicular to each other. The first direction is the width direction of the reactor test piece 100, the second direction is the length direction of the reactor test piece 100, and the third direction is the height direction of the reactor test piece 100.

[0077] The length, width, and height of the reactor components can be the length, width, and height directions during reactor testing in the operating state.

[0078] For example, the frame 113, the base plate 112, and the cover plate 120 can be connected by connectors. The position, type, and quantity of the connectors can be set by relevant technical personnel according to different needs.

[0079] In one example, a plug slot can be provided at each corner of the frame 113, and corresponding plugs can be provided on the cover plate 120 at the corresponding positions of the base plate 112, so as to realize the plug-in cooperation between the frame 113, the base plate 112 and the cover plate 120.

[0080] In another example, a connector can be provided at the midpoint of each side of the frame 113, and a corresponding connector slot can be provided on the cover plate 120 at the corresponding position of the base plate 112 to achieve the connector engagement between the frame 113, the base plate 112 and the cover plate 120.

[0081] In another example, the cross-section of the connector can be fan-shaped, or the cross-section of the connector can be rectangular.

[0082] In this embodiment, the frame 113, the base plate 112 and the cover plate 120 are connected by interlocking, so that the three can be tightly connected, thereby effectively preventing the multiple moving components 130 in the cavity 111 from sliding or falling off.

[0083] For example, combined Figure 9 The following example illustrates reactor test piece 100.

[0084] Figure 9 A schematic diagram of the architecture of a reactor test piece 100 provided in one embodiment of this application is shown. Figure 9 As shown, the reactor test piece 100 may include a base plate 112, a frame 113, a cover plate 120, and multiple movable components 130. Fan-shaped grooves are provided at the four corners of the frame 113, and correspondingly, fan-shaped bosses are provided at the corners of the base plate 112 and the cover plate 120. Furthermore, to ensure that the multiple movable components 130 can be placed as needed within the cavity 111 enclosed by the frame 113, the four corners of the inner contour of the frame 113 can be machined into chamfers consistent with the chamfered movable components 130, thereby achieving cooperation with the chamfered movable components 130.

[0085] It is understandable that the performance of a reactor component inspection system is determined not only by the system itself but also by the shape, material, and radiation attenuation capability of the object being inspected. Therefore, in this embodiment, by using the same material as the object being inspected to make the test piece, a strong correlation can be established between the same performance test and the object being inspected.

[0086] The above are specific embodiments of the reactor test piece 100 provided in this application. The reactor test piece 100 can be used in the performance verification method of the reactor component testing system provided in the following embodiments.

[0087] Figure 10 This application provides a schematic flowchart of a performance verification method for a reactor component testing system according to an embodiment of the present application. Figure 10 As shown, the performance verification method for the reactor component testing system includes the following steps S1010-S1030:

[0088] S1010. Obtain the actual location information corresponding to each defect in the reactor test piece.

[0089] The reactor test piece 100 includes a stage 110 containing a cavity 111; a cover plate 120 for sealing the cavity 111; and a plurality of movable components 130, wherein the plurality of movable components 130 are arranged in an array in the cavity 111, and the movable components 130 include defective movable components 131 and non-destructive movable components 132, and each defective movable component 131 includes at least one defect.

[0090] For example, multiple active components 130 are arranged in an array in the cavity 111 of the reactor test piece 100, and the defective active component 131 can be identified, along with the location information of the defect in the defective active component 131.

[0091] In one example, when arranging the active components 130 in the reactor test piece 100, technicians can record the location information corresponding to each defect and use this location information as the actual location information of the defect.

[0092] In another example, the actual location information corresponding to each defect can be determined by constructing models of different active components 130 and arranging each active component 130 according to the corresponding arrangement.

[0093] S1020. The reactor component inspection system detects the detection location information corresponding to each defect in the reactor test piece.

[0094] For example, the reactor test piece 100 can be placed at the center of the detection line of the reactor component detection system, so that the reactor component detection system can perform defect detection on the reactor test piece 100, thereby determining the location of each defect in the reactor test piece 100 and using it as the defect detection location information.

[0095] In one example, when the defect detection system is a CT scanner, the reactor test piece 100 can be placed at the center of the CT scanner's detection line, and a CT scan can be performed on the reactor test piece 100 to determine the detection location information corresponding to each defect. It is understood that, in this embodiment, obtaining the detection location information corresponding to each defect in the reactor test piece 100 using a CT scanner is merely illustrative; the detection location information can also be obtained through optical, ultrasonic, or other methods, and this application does not impose any limitations on this.

[0096] S1030. Determine the performance of the reactor component detection system based on the actual location information, the detection location information, and the performance verification indicators of the reactor component detection system.

[0097] For example, the performance verification index of the reactor component inspection system is used to characterize the performance standard of the reactor component inspection system. That is, if the reactor component inspection system meets the performance verification index, it can be determined that the reactor component inspection system has good performance and meets the performance requirements; otherwise, the reactor component inspection system has poor performance and cannot meet the performance requirements.

[0098] The performance verification metrics may include one or more. Different performance verification metrics can be used to evaluate the performance of the reactor component inspection system from different perspectives.

[0099] For example, the actual location information and detection location information corresponding to the defects in the reactor test piece 100 can be compared, and the performance of the reactor component detection system can be determined based on the comparison results and the performance verification indicators of the reactor component detection system.

[0100] For example, the performance of the reactor component inspection system can be used to characterize the reactor component inspection system's ability to detect various defects in the reactor test piece 100, that is, whether the reactor component inspection system can detect pore defects of different sizes and crack defects of different sizes in the reactor test piece 100.

[0101] In this embodiment, the actual location information corresponding to each defect in the reactor test piece 100 and the detection location information detected by the reactor component inspection system are obtained respectively. Based on the actual location information of the defects, the detection location information, and the performance verification indicators, the performance of the reactor component inspection system is determined. It is understood that using the reactor test piece 100 to perform performance testing on the reactor component inspection system enables the system to have better detection performance for test objects of the same material as the reactor test piece 100, thereby improving the accuracy and reliability of the system's detection results.

[0102] In order to obtain the detection location information corresponding to the defect, as another implementation of this application, another implementation of the reactor test piece 100 is also provided, as detailed in the following embodiments.

[0103] Figure 11 This illustration shows a flowchart of an embodiment of the present application for obtaining detection location information corresponding to a defect. Figure 11 As shown, the performance verification method for the reactor component testing system includes the following steps S1021-S1023:

[0104] S1021. Obtain inspection images of reactor test components through the reactor component inspection system.

[0105] For example, the reactor test piece 100 can be placed at the center of the detection line of the reactor component detection system, so that the reactor component detection system can perform defect detection on the reactor test piece 100, thereby obtaining the detection image of the reactor test piece 100, and then determining the location of each defect in the reactor test piece 100, and using it as the defect detection location information.

[0106] In one example, when the defect detection system is a CT scanner, the reactor test piece 100 can be placed at the center of the CT scanner's detection line, and the reactor test piece 100 can be CT scanned to obtain a CT image, and the defect identification results can be marked in the CT image.

[0107] S1022. Based on the defect recognition network, identify the detection image and determine the segmentation mask corresponding to the detection image.

[0108] For example, a segmentation mask can be a graph used to represent the classification results of different regions in an image. It can be a binary image, and different pixel values ​​can represent defective and non-defective regions. In one example, the pixel value of a defective region can be 1, and the pixel value of a non-defective location can be 0.

[0109] For example, a defect recognition network can be used to automatically identify defects in the detected image. The defect recognition network can generate a pixel-level segmentation mask for each detected defect, thereby accurately outlining the contours of each defect in the detected image.

[0110] S1023. Based on the segmentation mask corresponding to the detection image, determine the detection location information corresponding to each defect in the reactor test piece.

[0111] For example, defects in the detected image can be labeled according to the segmentation mask, thereby determining the defect region corresponding to each defect, and determining the detection location information corresponding to the defect based on the labeled defect region.

[0112] In one example, the center location of the defect area can be used as the detection location information corresponding to the defect.

[0113] In this embodiment, the defect recognition network identifies the detected image, which improves the speed of defect identification, shortens the defect detection time, and enhances the efficiency of defect detection. Furthermore, after determining the segmentation mask corresponding to the detected image through the defect recognition network, the detection location information corresponding to the defect can be determined based on the segmentation mask. It is understood that the segmentation mask, as a pixel-level image, can accurately locate defects and improve the accuracy of defect detection.

[0114] For example, the performance verification metrics include at least a first verification metric characterizing the false detection rate of defects and a second verification metric characterizing the missed detection rate of defects.

[0115] In order to realize the performance verification of the reactor component testing system, as another implementation of this application, another implementation of the reactor test piece 100 is also provided, as detailed in the following embodiments.

[0116] Figure 12 A schematic flowchart illustrating the performance determination of a reactor component testing system according to an embodiment of this application is shown. Figure 12 As shown, determining the performance of the reactor component testing system includes the following steps S1031-S1035:

[0117] S1031. Compare the actual location information corresponding to the defect with the detection location information corresponding to the defect to determine the number of false detections and the number of missed detections of the defect.

[0118] For example, technicians can compare the actual location information corresponding to the defect with the detection location information corresponding to the defect to determine the number of false positives and false negatives. For instance, the number of false positives and false negatives can be determined by comparing the area marked with defects in the CT scan image with the location of the defects in each of the recorded active components 130.

[0119] For example, the number of false positives and false negatives of defects can be determined by using a corresponding comparison algorithm.

[0120] S1032. Determine the total number of defects based on the actual location information corresponding to the defects.

[0121] For example, the number of actual location information corresponding to the defects can be counted, and the counted number can be used as the total number of defects.

[0122] S1033. Calculate the false detection rate of defects based on the total number of defects and the number of false detections of defects.

[0123] For example, the false detection rate of a defect can be calculated using the following formula (1):

[0124]

[0125] S1034. Calculate the defect miss rate based on the total number of defects and the number of defects missed.

[0126] For example, the false detection rate of a defect can be calculated using the following formula (2):

[0127]

[0128] S1035. Determine the performance of the reactor component detection system based on the false detection rate, false negative rate, first verification index, and second verification index.

[0129] For example, if the false detection rate is less than or equal to the first verification index and the false detection rate is less than or equal to the second verification index, the performance of the reactor component detection system is determined to be good; conversely, if the false detection rate is greater than the first verification index or the false detection rate is greater than the second verification index, the performance of the reactor component detection system is determined to be poor.

[0130] In this embodiment of the application, by using the defect false detection rate and defect missed detection rate as evaluation criteria for the performance of the reactor component detection system, the accuracy and reliability of the detection system can be comprehensively and objectively evaluated, providing a basis for the optimization and improvement of the detection system.

[0131] In order to improve the accuracy of performance evaluation of the reactor component testing system, as another implementation of this application, another implementation of the reactor test piece 100 is provided, as detailed in the following embodiments.

[0132] Figure 13 A schematic flowchart illustrating a performance verification method for a reactor component testing system according to an embodiment of this application is shown. Figure 13 As shown, the performance verification method for the reactor component testing system includes the following steps S1310-S1023:

[0133] S1310. Obtain the actual location information corresponding to each defect in the reactor test piece.

[0134] S1320. The reactor component inspection system detects the detection location information corresponding to each defect in the reactor test piece.

[0135] S1330, The number of times the reactor component inspection system performs defect detection.

[0136] S1340. Determine whether the number of detections meets the preset detection threshold. If yes, execute S1350; otherwise, execute S1360.

[0137] S1350. Based on the performance verification indicators of the reactor component detection system, the actual position information corresponding to different placement postures of the active components, and the detection position information, determine the performance of the reactor component detection system.

[0138] S1360, Adjust the placement of the active components.

[0139] In some embodiments, steps S1310-S1320 are the same as steps S1010-S1020, and will not be described in detail here.

[0140] In some embodiments, in S1330, the number of times the reactor component detection system performs defect detection can be counted.

[0141] In one example, a counter can be used to count the number of defect detections performed by the reactor component inspection system. For instance, a counter variable can be maintained in the memory of the reactor component inspection system, and the counter can be incremented by one each time a defect detection is performed.

[0142] In another example, the number of times the reactor component inspection system performs defect detection can be determined by technicians.

[0143] In some embodiments, in S1340, it can be determined whether the number of detections meets the preset detection number threshold. If it is determined that the number of detections meets the preset detection number threshold, S1350 is executed, that is, the performance of the reactor component detection system is determined based on the performance verification index of the reactor construction detection system, the actual position information corresponding to different placement postures of the active components, and the detection position information. If it is determined that the number of detections does not meet the preset detection number threshold, S1360 is executed, that is, the placement posture of the active component 130 is adjusted, and the step of obtaining the actual position information corresponding to each defect in the reactor test piece 100 is returned until the number of detections meets the preset detection number threshold.

[0144] For example, the preset detection number threshold can be determined in advance by relevant technical personnel according to different detection needs. For instance, the preset detection number threshold can be set to 10 times, meaning that the reactor construction detection system needs to perform 10 defect detections.

[0145] If the number of inspections has not reached the preset inspection threshold, the placement orientation of the movable component 130 can be adjusted. Adjusting the orientation of the movable component 130 may include replacing the movable component 130 in the cavity 111 and changing the orientation of each defect in the movable component 130 in the cavity 111.

[0146] In some alternative embodiments, Figure 14 A flowchart illustrating the process of determining the placement orientation of an active component according to an embodiment of this application is shown. Figure 14 As shown, determining the placement orientation of the active components includes the following steps S1361-S1365:

[0147] S1361. Identify the active components to be adjusted.

[0148] For example, the movable components 130 to be adjusted can be determined according to their arrangement. The arrangement can be a serpentine pattern of the movable components 130 arranged from bottom to top within the cavity 111; or, the movable components 130 can be arranged from bottom to top and from left to right. Furthermore, the movable components 130 can be adjusted one by one according to their arrangement, i.e., the movable components 130 to be adjusted are determined according to their arrangement.

[0149] S1362. Generate a first random number representing the active component 130 and a second random number representing the orientation of the active component according to a preset random number algorithm.

[0150] For example, a technician may label each active component 130, thereby giving each active component 130 a unique label that identifies it.

[0151] Furthermore, technicians can assign labels to different orientations of the active component 130. In one example, due to the location of the defect in the defective active component 131, the active component 130 can have 24 orientations, each corresponding to a number.

[0152] For example, for each position in the cavity 111, two random numbers can be generated using a preset random number algorithm. One is used to characterize the active component 130, and the other is used to characterize the orientation of the active component 130.

[0153] Specifically, when generating the first random number using the preset random number algorithm, the size of the first random number cannot exceed the size of the number corresponding to the identity label of the activity component 130. Similarly, when generating the second random number using the preset random number algorithm, the size of the second random number cannot exceed the size of the number corresponding to the orientation. Furthermore, to improve the fairness and reliability of the verification process, the proportion of defective activity components 131 determined by the preset random number algorithm to all activity components 130 must exceed a first threshold, and among the determined defective activity components 131, there must be at least one defective activity component 131 of each different defect type.

[0154] S1363. Determine the target activity component corresponding to the first random number according to the first preset correspondence relationship.

[0155] The first preset correspondence represents the correspondence between different first random numbers and different activity components 130.

[0156] For example, a target activity component 130 corresponding to a first random number can be selected from a plurality of activity components 130 through a first preset relationship.

[0157] S1364. Determine the target location corresponding to the second random number according to the second preset correspondence.

[0158] The second preset correspondence represents the correspondence between different second random numbers and different positions of the activity component 130.

[0159] For example, the target direction corresponding to the second random number can be determined through the second preset relationship.

[0160] S1365. Place the target activity component at the position corresponding to the activity component to be adjusted according to the target orientation.

[0161] For example, the target active component 130 can be placed at the position corresponding to the active component 130 to be adjusted according to the target orientation, so as to realize the adjustment of the active component 130.

[0162] For example, after the activity component 130 to be adjusted is adjusted, the activity component 130 to be adjusted can be updated in a different manner, thereby realizing the adjustment of multiple activity components 130.

[0163] In this embodiment, a first random number representing the active component 130 and a second random number representing the orientation of the active component 130 are generated according to a preset random number algorithm. Based on a first preset correspondence, the target active component 130 corresponding to the first random number is determined, and based on the second preset correspondence, the target orientation corresponding to the second random number is determined. The target active component 130 is then placed at the position corresponding to the active component 130 to be adjusted, according to the target orientation, thereby achieving the adjustment of the active component 130. In this embodiment, by using a preset random number algorithm to determine the identity and orientation of the active component 130 to be adjusted, the unpredictability of the component to be adjusted is ensured, thereby guaranteeing the fairness and reliability of the system performance verification.

[0164] Furthermore, if the number of tests meets the preset test number threshold, the performance of the reactor component testing system can be determined based on the performance verification indicators of the reactor component testing system, the actual position information corresponding to different placement postures of the active component 130, and the test position information.

[0165] In some alternative embodiments, Figure 15 A schematic flowchart illustrating the performance determination of a reactor component testing system according to an embodiment of this application is shown. Figure 15 As shown, determining the performance of the reactor component inspection system includes the following steps S1351-S1353:

[0166] S1351. Based on the actual position information and detection position information corresponding to the placement posture of each active component, determine the calculated values ​​of the verification parameters of the reactor component detection system under different placement postures.

[0167] For example, for each type of active component 130, the actual location information and detection location information corresponding to the defects in the reactor test piece 100 can be obtained respectively. Based on the placement attitude of each active component 130, the actual location information and detection location information corresponding to the defects in the reactor test piece 100 can be used to calculate the verification parameter values ​​of the reactor component detection system.

[0168] In one example, the false detection rate and false negative rate of the reactor component detection system can be calculated for each type of active component 130 under different placement orientations.

[0169] S1352, The number of target verification parameter calculation values ​​that satisfy the performance verification index.

[0170] For example, after multiple tests are performed by the reactor component testing system, the number of calculated values ​​of the verification parameters that meet the target verification parameters for the performance verification indicators is counted.

[0171] Understandably, after arranging the multiple moving components 130 of the reactor test piece 100, the actual location information and detection location information corresponding to the defects are determined, and the false detection rate and false negative rate of defects in this inspection process are calculated. It is then determined whether the number of inspections by the reactor component inspection system has reached the preset number of inspections. If it is determined that the preset number of inspections has not been reached, the multiple moving components 130 are adjusted, and the above process is repeated until the number of inspections by the reactor component inspection system reaches the preset number of inspections.

[0172] Furthermore, by comparing the defect false detection rate and defect missed detection rate determined in each testing process with the performance verification index, the calculated values ​​of the target verification parameters that meet the performance verification index are determined, and their quantity is determined.

[0173] S1353. Determine the performance of the reactor component detection system based on the number of calculated values ​​of the target verification parameters and the preset performance verification conditions of the detection system.

[0174] For example, preset performance verification conditions for the detection system can be used to measure the performance of the reactor component detection system in multiple tests.

[0175] In one example, the preset performance verification condition of the detection system can be that the number of calculated values ​​of the target verification parameter is greater than a second quantity threshold; or, the preset performance verification condition of the detection system can be that the number of calculated values ​​of the target verification parameter is greater than a preset threshold and is continuous.

[0176] In this embodiment, the performance of the reactor component detection system is determined by measuring the relationship between the calculated values ​​of multiple verification parameters and the performance verification index, thus achieving better accuracy in evaluating the performance of the reactor component detection system.

[0177] In this embodiment, the number of defect detections performed by the reactor component detection system is counted. If the number of detections does not meet a preset threshold, the placement of the active component 130 is adjusted, and the process returns to obtaining the actual location information corresponding to each defect in the reactor test piece 100, until the number of detections reaches the preset threshold. The performance of the reactor component detection system is evaluated using multiple sets of actual location information and detection location information, thereby improving the accuracy of the performance evaluation of the reactor component detection system.

[0178] In some optional embodiments, the detection location information can be the location information obtained by the reactor component detection system scanning the reactor test piece 100 according to preset system parameters. Therefore, if it is determined that the performance of the reactor component detection system does not meet the performance requirements, the system parameters are adjusted.

[0179] For example, the preset system parameters may include at least the scanning speed, that is, the reactor component detection system may scan the reactor test piece 100 according to a preset trajectory, such as a spiral trajectory, and at a preset scanning speed.

[0180] Furthermore, if the performance of the reactor component inspection system is determined to be insufficient to meet performance requirements, system parameters can be adjusted to enhance the system's performance. For example, the scanning speed can be reduced to obtain clearer inspection images, thereby enabling more accurate defect localization.

[0181] In this embodiment of the application, if it is determined that the performance of the reactor component detection system does not meet the performance requirements, the performance of the reactor component detection system can be enhanced by adjusting the system parameters.

[0182] Based on the performance verification method for the reactor component testing system provided in the above embodiments, this application also provides a specific implementation of the performance verification device for the reactor component testing system. Please refer to the following embodiments.

[0183] First see Figure 16 The performance verification device for the reactor component testing system provided in this application includes the following modules:

[0192] In one embodiment, the performance verification indicators include at least a first verification indicator characterizing the false detection rate of defects and a second verification indicator characterizing the false negative rate of defects.
