[0002] Core-related components are crucial components within the reactor, playing a vital role in its safe and stable operation. These components work directly with the fuel assemblies within the core and have certain auxiliary functions.

[0003] The WABA rod and the pressing component are important components of the burnable poison assembly in the relevant components. The WABA rod is connected to the pressing component through the upper end plug component. Therefore, the upper end plug component is the key component for the WABA rod to bear the weight. At the same time, the WABA rod is washed by the water flow in the reactor, which will produce slight vibrations, which will also cause the upper end plug and the connecting sleeve to loosen. The upper end plug component is composed of a 304 stainless steel upper end plug and a zirconium alloy connecting tube through a crimping process (see the crimping position for details). Figure 1 ), so the size inspection of the upper end plug component after the crimping process is an important inspection indicator. The existing inspection method is to use caliper measurement (measurement position see Figure 1 ), record the measurement data, each data needs to be measured multiple times, and after measurement, it needs to be compared one by one with the technical parameters. Due to the large error of manual measurement and low measurement efficiency, the waiting time for subsequent processes is long.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings 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 making creative efforts shall fall within the scope of protection of the present invention.

[0024] The original inspection method used calipers to measure each dimension five times, for a total of 15 manual measurements of the three dimensions. The measurement data was manually recorded and compared one-to-one with the two technical parameters of each group. A single component required at least 30 inspections and comparisons. This resulted in low inspection efficiency and large manual measurement errors, leading to long waiting times for subsequent processes. The mold opening tolerances of this application have been calculated to ensure accurate dimensional inspection during measurement. Furthermore, the system integrates three dimensions into one, allowing for a single measurement result. This system achieves both high inspection efficiency and high accuracy.

[0025] This application provides a detection tool for WABA upper end plug components, reference Figure 2 , comprising a box body 7, a mold cover plate is installed on the top of the box body 7; a mold hole 1 is opened on the mold cover plate, and the shape of the mold hole 1 matches the shape of the upper end plug component; The die opening hole 1 includes a first length measuring position, a second length measuring position and a connection diameter measuring position.

[0026] refer to Figure 1 The upper end plug component is assembled by pressing and crimping the upper end plug component and the connecting pipe component. If the pressing is not in place, the component will be too long. If the crimping is not in place, the pleated part of the component will be too large. The die hole 1 is formed by precise die opening on the contactable material; the shape and size of the die hole 1 are carefully measured and designed, among which the overall length of the upper end plug component, the length from the shoulder to the bottom of the upper end plug component, and the diameter of the pleat of the upper end plug component are precisely measured. At the same time, the tolerance range of the designed die hole 1 can ensure that the qualified parts tested are within the requirements of the drawing and accurately match the shape of the WABA rod upper end plug component. Only parts with qualified size and shape can pass through the die hole 1 smoothly; the lower limit of the size of the die hole 1 is the upper limit of the size of the qualified upper end plug component; the number one length measurement position corresponds to Figure 1 At point a of the upper end plug component, the second length measurement position corresponds to Figure 1 The length at point b corresponds to the connection diameter measurement position Figure 1Point c in the figure is also the crimping position of the upper end plug component and the connecting pipe component.

[0027] During the inspection, the operator places the upper end plug component accurately above the mold hole 1 according to the mold shape direction. Under the action of gravity, the qualified upper end plug component falls into the box body 7 and enters the interior of the box body 7 through the mold hole 1. It is qualified; if the upper end plug component is not pressed into place or crimped into place, it cannot pass through the mold hole 1 and is judged as unqualified and cannot pass, ensuring accuracy and pertinence.

[0028] At the same time, the accommodating space of the box body 7 is formed by five plates fixed by bolts 6. Figure 2 Reference numeral d represents a bolt 6 for fixing the box body 7. The box body 7 is not only a component detection box body 7, but also has the function of storing components. It can accommodate components after the current batch of detection is completed, providing convenience for subsequent use. At the same time, the tool box body 7 serves as the framework of the entire detection tool, playing a role of stable support and positioning, and providing a reliable platform for the installation and operation of other components.

[0029] The present application integrates the detection tool into the mold hole 1 of the upper end plug component's outer shape, thereby integrating the three-dimensional detection of the upper end plug component into one, thereby achieving accurate and efficient detection.

[0030] In one embodiment of the present invention, the mold opening cover plate includes a fixed cover plate 2 and a movable cover plate 4; the mold opening hole 1 is provided on the fixed cover plate 2; and a rotating connecting member 3 is provided between the fixed cover plate 2 and the movable cover plate 4.

[0031] In one embodiment of the present invention, the rotating connection member 3 includes blades and an articulated arm; both ends of the articulated arm are rotatably connected to blades, and the two blades are fixedly connected to the fixed cover plate 2 and the movable cover plate 4 respectively.

[0032] The blades are fixed to the movable cover plate 4 and the fixed cover plate 2 by bolts 6. After the qualified upper end plug components pass through and enter the interior of the box body 7, when the qualified upper end plug components need to be taken out, the movable cover plate 4 is opened, and the movable cover plate 4 is rotated and opened around the fixed cover plate 2 to carry out batch testing, storage and taking out, which increases the flexibility of the tool, and the components can be taken out according to actual usage conditions, which is convenient for the use of the components after testing, so that the entire testing tool can work together and facilitate the taking out of components.

[0033] In one embodiment of the present invention, referring to Figure 3 A buffer block 8 is installed inside the box body 7 at one end close to the fixed cover plate 2.

[0034] In one embodiment of the present invention, the buffer block 8 is triangular in shape, and the hypotenuse of the buffer block 8 faces one end of the movable cover 4 .

[0035] In the process of the qualified upper end plug component passing through the mold hole 1 and entering the box body 7, it first passes through the triangular buffer block 8 and moves along the oblique side of the buffer block 8 toward one end of the movable cover 4, so as to achieve buffering of the upper end plug component to avoid collision while making the upper end plug component move toward one end of the movable cover 4 in a concentrated manner, which is convenient for the later removal of the upper end plug component.

[0036] In one embodiment of the present invention, the buffer block 8 is detachably connected to the inner wall of the box body 7 .

[0037] In one embodiment of the present invention, the buffer block 8 includes a fixing portion and a buffer portion; the fixing portion is detachably connected to the side wall of the box body 7, and the buffer portion is detachably connected to the fixing portion.

[0038] In one embodiment of the present invention, the buffer portion is made of nylon or polyethylene.

[0039] In one embodiment of the present invention, the fixing portion is connected to the inner wall of the box body 7 via bolts 6 .

[0040] The buffer block 8 is provided to fully consider the protection of the upper end plug component during the falling process. When the upper end plug component falls along the die opening 1, the buffer block 8 effectively buffers the impact force, avoids the component from being damaged due to collision, and ensures that the integrity and performance of the component are not affected. The buffer block 8 is divided into a fixed part and a buffer part. On the one hand, the buffering effect on the upper end plug component is further improved by the material properties of the buffer part without affecting the detachable connection between the fixed part and the box body 7; the connection is disassembled by screws, and the use of bolts 6 ensures the stability of the entire detection tool structure, and can maintain a good working condition during long-term use. After long-term use, if the buffer part becomes fatigued, the buffer block 8 can be taken out and the buffer part can be replaced. The buffer part and the fixed part can be connected by various means such as snapping or gluing.

[0041] In one embodiment of the present invention, a handle 5 is installed on the movable cover 4 .

[0042] After the test is completed, when it is needed later, the operator lifts the handle 5 upwards, and the handle 5 can drive the movable cover 4 to rise, so that the upper end plug component after measurement can be easily taken out. The design of the handle 5 conforms to the principle of ergonomics, which is convenient for the operator to operate easily.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
