Fig. 1 shows a schematic structural view of a support apparatus 100 for a nuclear reactor assembly 6 according to an exemplary embodiment of the present invention, fig. 3 shows a schematic structural view of a positioning block 21 of the support apparatus 100 of fig. 1, and fig. 4 shows a schematic structural view of a slider 22 of the support apparatus 100 of fig. 1. As shown in fig. 1, 3 and 4, the supporting device 100 includes: the nuclear reactor component mounting structure comprises a supporting seat 1, wherein the supporting seat 1 is provided with a plurality of accommodating holes 11 and is used for accommodating pins 61 of a plurality of nuclear reactor components 6; and an attitude adjusting unit 2, the attitude adjusting unit 2 being provided to the support base 1 and adjusting an attitude of the nuclear reactor component placed in the accommodating hole 11, wherein the attitude adjusting unit 2 includes a positioning block 21 and a slider 22, the slider 22 includes a first end 221 provided as a V-shaped groove and a second end 222 provided as a flat surface, and the slider 22 is slidable with respect to the positioning block 21.
In the support apparatus 100 for a nuclear reactor assembly 6 according to the embodiment of the present invention, by providing the posture adjustment unit 2 on the cradle 1, the nuclear reactor assembly 6 can be adjusted to a preset posture while supporting the nuclear reactor assembly 6; by providing a slide 22 that can slide with respect to the positioning block 21, the nuclear reactor component 6 can be adjusted to a preset posture that fits the end of the slide 22 by means of the movement of the slide 22; by providing the slide 22 to include the first end 221 in the form of a V-shaped groove and the second end 222 in the form of a flat surface, it is possible to perform attitude adjustment for different types of arrays of nuclear reactor components.
Fig. 2 shows a schematic structural view of the nuclear reactor assembly 6 supported by the support device 100 of fig. 1, and as shown in fig. 2, the nuclear reactor assembly 6 includes a main body portion 62 and pins 61, and the pins 61 are formed at longitudinal ends of the main body portion 62. The main body part 62 has a regular hexagonal prism structure, and the pins 61 have a cylindrical structure. The radial dimension of the pins 61 may be constricted relative to the body portion 62. The nuclear reactor assembly 6 includes a nuclear fuel assembly having a body portion 62 configured to contain nuclear fuel within a fuel region.
The plurality of receiving holes 11 may be circular holes for fitting with the pins 61 of the nuclear reactor component 6, and after the pins 61 are inserted into the receiving holes 11, the radial dimension of the main body portion is larger, so that the main body portion 62 is not inserted into the receiving holes 11, and therefore, the main body portion 62 is exposed out of the receiving holes 11. The supporting seat 1 can be of a block structure, the accommodating holes 11 can be through holes, and the axial length of each through hole can be slightly larger than that of the corresponding pin 61, so that on one hand, materials for manufacturing the supporting seat 1 can be saved, and on the other hand, if foreign matters fall into the through holes, the supporting seat can be cleaned conveniently.
In the out-of-core deformation test of the nuclear reactor assembly, the deformation condition of an array of the nuclear reactor assembly which is arranged in a single row mode and a sector mode under different thermal gradients and the interaction force among the assemblies need to be researched. Accordingly, the plurality of receiving holes 11 of the present application are arranged in the single row array a and the triangular array B. The small gap between adjacent nuclear reactor assemblies 6 allows the regular hexagonal prism structures of adjacent body portions 62 to be formed only in a face-to-face arrangement. If the main body portion 62 of the nuclear reactor component 6, which has been inserted into one receiving hole 11, faces the other receiving hole 11 adjacent thereto with the edge, the nuclear reactor component 6 cannot be inserted into the other receiving hole 11. Therefore, it is necessary to adjust the posture of the nuclear reactor component 6 inserted into the receiving hole 11 so that the surface thereof faces the receiving hole 11 adjacent thereto, thereby facilitating the smooth insertion of another nuclear reactor component 6.
Referring to fig. 1, the single-row array a and the triangular array B may be combined, the plurality of receiving holes 11 of the single-row array a may be used as the base of the triangular array B, and the common use of the plurality of receiving holes 11 may make the apparatus more compact while saving materials. Correspondingly, the supporting seat 1 may include a rectangular parallelepiped structure and a triangular prism structure, the single-row array a is disposed in the rectangular parallelepiped structure, and the triangular array B is disposed in the triangular prism structure. By combining the single-row array A and the triangular array B together, the supporting device 100 can be used for carrying out multiple off-stack tests such as a single-component thermal deformation test, a single-row component thermal deformation test and a 60-degree sector component thermal deformation test, and is multifunctional. Meanwhile, the auxiliary devices adopted by each test can be shared, when the tests to be developed are changed, the auxiliary devices only need to be slightly adjusted, the operation is convenient, and the utilization degree is high.
In one embodiment, the symmetry line of the single-row array a coincides with the symmetry line of the triangular array B, and correspondingly, the triangular prism structure is spliced to the middle of the rectangular structure, so that the whole supporting seat 1 forms a bilateral symmetry structure. This ensures that the center of gravity of the entire apparatus is stabilized after the plurality of nuclear reactor components 6 are inserted into the plurality of receiving holes 11, and prevents the center of gravity of the apparatus from being shifted to one side.
The supporting seat 1 can be integrally formed without welding assembly, so that the cuboid structure and the triangular prism structure can be firmly combined together, the shape and position accuracy is high, the rigidity is high, and the mutual displacement of the cuboid structure and the triangular prism structure caused by the acting force formed by inserting a plurality of nuclear reactor components 6 can be avoided. The cuboid structure and the triangular prism structure of the supporting seat 1 can adopt arc transition to reduce stress concentration. After the supporting seat 1 is formed, a plurality of accommodating holes 11 can be formed in the supporting seat through a drilling mode, machining is simple, cost is low, the thickness of the hole wall can reach the maximum value of theoretical design, the wall surface between the formed accommodating holes 11 is thick, rigidity is high, and the supporting seat is not prone to stress deformation. The pitch of the plurality of receiving holes 11 may be uniform.
The plurality of receiving holes 11 of the single-row array a are aligned in a straight line, and for example, the single-row array a may be configured by 16 receiving holes 11 aligned in a straight line. The plurality of receiving holes 11 of the triangular array B may be arranged in the shape of an isosceles triangle, which is equivalent to being arranged in a sector. In one embodiment, the plurality of receiving holes 11 of the triangular array B may be arranged in the shape of an equilateral triangle, which corresponds to a 60 ° sector. For example, the triangular array B may be formed by arranging 21 receiving holes in an equilateral triangle, which includes six rows, the number of each row is 1, 2, 3, 4, 5, and 6 in sequence, the number of the receiving holes on each side of the equilateral triangle is 6, and the 6 receiving holes 11 on the bottom side are also part of the receiving holes 11 that form the single-row array a.
The posture adjustment units 2 may be provided in plural numbers, and are disposed at least one end of the single-row array a, and/or outside the vertex angle of the triangular array B. Referring to fig. 1, 3 and 4, the body 62 of the nuclear reactor assembly 6 disposed at the end of the single row array a is mated to the second end 222 of the slide 22, and/or the body 62 of the nuclear reactor assembly 6 disposed at the apex of the triangular array B is mated to the first end 221 of the slide 22. The spacing between the plurality of receiving holes 11 is such that adjacent nuclear reactor assemblies 6 can be positioned relative to one another.
In the attitude adjusting unit 2 provided at least one end of the single row array a, the sliding direction of the slider 22 with respect to the positioning block 21 coincides with the extending direction of the single row array a. After the nuclear reactor assembly 6 is inserted into the accommodating hole 11 at the end of the single-row array a, the sliding block 22 is slid towards the direction of the nuclear reactor assembly 6, and during the sliding process, the second end 222 of the sliding block 22 pushes the main body part 62 of the nuclear reactor assembly 6, so that the nuclear reactor assembly 6 rotates in the accommodating hole 11 until the main body part 62 stops rotating when being matched with the second end part 222, and the posture of the nuclear reactor assembly 6 is determined. At this time, the regular hexagonal prism structure of the main body portion 62 faces the accommodation hole 11 adjacent thereto with a surface. Due to the small distance between the receiving openings 11, the insertion of a further nuclear reactor assembly 6 is only possible when it is in a surface-to-surface engagement with the nuclear reactor assembly 6 in the defined position.
From this, it is understood that, after the posture of the nuclear reactor component 6 located at the end is determined, the nuclear reactor component 6 provided in the other accommodation hole 11 of the single row array a can automatically determine the posture based on this. The posture adjustment unit 2 may be provided at one end of the single row array a, thereby gradually inserting the plurality of nuclear reactor components 6 from the one end in one direction. The adjustment units 2 may be simultaneously disposed at both ends of the single-row array a, so that a plurality of nuclear reactor assemblies 6 may be gradually inserted from both ends in opposite directions, and the posture of the nuclear reactor assemblies 6 may be more stably maintained.
For the attitude adjusting unit 2 provided outside the vertex angle of the triangular array B, the sliding direction of the slider 22 with respect to the positioning block 21 coincides with the direction in which the line of symmetry of the triangular array B is located. The V-shaped groove of the first end 221 of the slider 22 may be 120 deg. so as to be able to cooperate with the corner of a regular hexagonal prism. Similarly, after the nuclear reactor assembly 6 is inserted into the receiving hole 11 at the top corner of the triangular array B, the slider 22 is slid toward the direction of the nuclear reactor assembly 6, and during the sliding process, the first end 221 of the slider 22 pushes the main body 62 of the nuclear reactor assembly 6, so that the nuclear reactor assembly 6 rotates in the receiving hole 11 until the main body 62 stops rotating when being matched with the first end 221, and the posture of the nuclear reactor assembly 6 is determined. At this time, the regular hexagonal prism structure of the main body portion 62 faces the accommodation hole 11 adjacent thereto with a surface. Due to the small distance between the receiving openings 11, when another nuclear reactor component 6 is inserted, it can only be inserted in a surface-to-surface fit manner with the nuclear reactor component 6 having the determined posture, so that the posture of the other nuclear reactor component 6 is automatically determined.
The slide 22 can be disposed on the positioning block 21 in different directions so that the first end 221 or the second end 222 can be selected to mate with the body portion 62 of the nuclear reactor assembly 6. The positioning block 21 is fixedly provided to the support block 1, and when the slider 22 is provided to the positioning block 21, the installation direction of the slider 22 is adjusted as needed so that the first end 221 or the second end 222 faces the nuclear reactor assembly 6.
Referring to fig. 3 and 4, the positioning block 21 may include a slide groove 211, and the slider 22 includes a convex sliding portion 223, the sliding portion 223 sliding within the slide groove 211 so that the slider 22 can slide with respect to the positioning block 21. The slider 22 may include a positioning pin hole 224, the positioning block 21 includes a fitting hole 212 for fitting with a positioning pin, the positioning pin hole 224 is a long hole, and the number of the positioning pin holes 224 may be two, and the two positioning pin holes are provided on both sides of the sliding portion 223. After the position of the slider 22 on the positioning block 21 is determined, the slider 22 can be fixed to the positioning block 21 by passing a positioning pin through the positioning pin hole 224 and the fitting hole 212, and the position of the slider 22 can be locked. When the positioning pin is released, the sliding portion 223 may move along the slide groove 211; when the positioning pin is fastened, the slider 22 may be fixed to the positioning block 21.
The positioning block 21 may have a plurality of first connection holes 213, the supporting base 1 may have a plurality of corresponding second connection holes, and the positioning block 21 may be fixed to the supporting base 1 by using a connection member to pass through the first connection holes 213 and the second connection holes. Of course, the positioning block 21 may also be fixedly connected to the supporting seat 1 by other means, such as welding, bonding, etc.
The side wall of the supporting seat 1 is provided with a plurality of side grooves 12 at positions close to the bottom, and a plurality of mounting holes 13 are formed between the groove surfaces of the side grooves 12 and the bottom surface of the supporting seat and used for fixedly mounting the supporting seat 1 to the ground, so that the supporting seat 1 is not easily influenced by the outside to move, and the repeated positioning precision is high when a repeated test is carried out. The side grooves 12 may be square grooves, and mounting holes 13 are formed in the bottom groove surfaces of the square grooves. The side grooves 12 do not interfere with the accommodating holes 11, a certain distance is left between the side grooves 12 and the bottom of the supporting seat 1, and the side grooves 12 can be symmetrically distributed on the supporting seat 1. The mounting holes 13 may be threaded holes, which cooperate with screws to fix the bearing block 1 to the ground. The inner diameter of the screw hole may be slightly larger than the outer diameter of the screw.
