    摘要: The present invention relates to a pull-in rod type loader for loading fuel rods efficiently and conveniently from a fuel rod magazine to a fuel assembly. The control rod pipes and fuel rods are held in assigned grid cells, respectively termed pipe-cells and fuel-rod-cells, in each quadrant section of a grid. The control rod pipes are disposed in a quadrant so that the locations of the pipe-cells assigned for the guide pipes in one quadrant are symmetrical with respect to a central rotational axis of the apparatus. The grid cells and the pull-in loader are both aligned with respect to a central rotational axis. To load the fuel rods into the fuel assembly, only the pull-in rods need to be operated for every 90 degree rotation of the loader about the central axis, because the locations of the pull-in rods correspond exactly with the grid cells assigned to hold fuel rods. This type of loader does not require complex switching devices required in the conventional pull-in rod type of loaders, and the assembling operation can be carried out efficiently and quickly.

    摘要: In the nuclear fuel assembly, a plurality of plate-shaped straps are assembled perpendicularly to each other into a grid shape so as to construct a supporting grid providing with a plurality of cells each of which inserts a nuclear fuel rod. A cell-size inspection device which inspects the size of each cell of the supporting grid is constructed by a base, a movable plate, a plurality of pin gauges and a sensor. The supporting grid is mounted on the base, while the movable plate is provided such that it can relatively move with respect to the base in a longitudinal direction of the cells. The pin gauges are provided on the movable plate such that they can freely slide along the longitudinal direction of the cells. When the movable plate is moved toward the supporting grid, each of the pin gauges is to be inserted into each of the cells. The sensor senses whether the pin gauge is relatively moved from the predetermined position of the movable plate. By simply inserting the pin gauge into the cell, it is possible to inspect the cell size with respect to a plenty of cells provided in the supporting grid. Thus, it is possible to inspect all of the cells in an extremely short time, which remarkably reduces the time and cost required for performing the inspection process on the nuclear fuel assembly.

    摘要: A key member, a method for insertion and/or removal of the fuel rods in a nuclear fuel assembly using the key member and a method of disassembling the nuclear fuel assembly using the same key member are disclosed. The key member has first projections and second projections formed on the opposite faces of an elongated key body. In the insertion or removal of the fuel rods or in the disassembling the nuclear fuel assembly, the key member is inserted into the grid and rotated to bring the first projections and the second projections into engagement with the straps of the grids and the springs on the straps to thereby the springs are deflected in a direction away from the dimples opposing to the springs. In this situation, the insertion and removal of the fuel rods can be carried out. Further, in disassembling the nuclear fuel assembly, space required for inserting the key member into the grids may be ensured by subjecting prescribed portions of control rod-guide pipes and instrumentation pipes to cutting work and bulging the cut ends to move the cut end away from that of the opposing cut ends of the cut piece. The space may be formed by removing the control rod-guide pipes and instrumentation pipes after having formed slits in the pipes.

    摘要: In a grid in a nuclear fuel assembly for supporting fuel rods, elongated straps intersect with each other to define grid cells. At least one pair of punched sections are formed, in spaced relation to each other, in each of peripheral walls of the respective grid cells. At least one of elongated spring elements is formed in the peripheral wall of each grid cell. Each spring element is formed such that a portion of the peripheral wall of the grid cell between the pair of punched sections bulges and projects into the grid cell. The spring element is capable of being deflected toward the peripheral wall of the grid cell. A pair of projections are formed in the peripheral wall of the grid cell respectively at both longitudinal ends of the spring element such that a pair of portions of the peripheral wall of the grid cell bulge. Both longitudinal ends of the spring element are connected respectively to the pair of projections.

    摘要: A grid structure is presented in which grid cells are formed by orthogonally intersecting straps prefitted in the longitudinal direction with a plurality of slitted spring frame members. Therefore, when the straps are assembled, the spring frame members are also orthogonally intersected. The spring frame members are made of Inconel and provided with welding tabs while the straps are made of zircalloy and provided with their own welding tabs. Therefore, welding can be performed to firmly join the spring frame members to each other while the straps can also be welded firmly to weld the like metals. The spring sections are thus firmly joined and attached to the straps which are firmly joined. The grid of this configuration thus provides an excellent service life without the losing The fuel rod retaining power, which would result from neutron radiation and thermal damages on holding devices made of zircalloy.

    摘要: In a method of assembling a nuclear fuel assembly, a deflecting jig is inserted into grid cells in each of a plurality of grids. The diameter of the deflecting jig is enlarged to urge a spring of at least one pair of dimples and spring, associated with the grid cell to deflect the springs away from the dimple. A plurality of elongated key members are inserted into the grid cells through a plurality of openings defined at intersections between the straps forming walls of the grid cells. Each key member is rotated about its axis to cause hooks of the key member to project from a wall surface of the strap in a direction opposite to the projecting direction of the springs. The key member is then moved in a direction to engage the hooks with the wall surface of the strap. Urging of the spring by the deflecting jig is released to allow the same to be withdrawn from the grid cells and, subsequently, the fuel rods are inserted into the respective grid cells. The key member is then moved in a direction to bring the springs into pressure contact with the fuel rods. The key members are then withdrawn from the grid cells. A combination of the grid and the key member is also provided.
