Title: Supporting grating for fuel assembly of nuclear reactor
Inventor: SUZUKI KAZUICHI
IPC: G21C3/34
Filed: 1987-05-20
Abstract: PURPOSE:To prevent flawing of the peripheral faces of fuel rods at the time of loading the fuel rods by loading the fuel rods into respective cells in the state in which square cylindrical deforming means are not inserted into square cylinders, then inserting the square cylindrical deforming means into the cylinders to press the peripheral face parts of the square cylinders toward the outside. CONSTITUTION:The square cylinder 10 having a square section is disposed at the center of a space A divided internally with four cells 8 by means of vertical straps 5 and horizontal straps 6. Springs 10' are integrally formed by blanking to the central parts on the respective peripheral faces of the cylinder 10. The springs 10' are deformed outward by inserting a pipe 11, which is the square cylindrical deforming means, into the square cylinder. The fuel rods F are first inserted down to the prescribed position in the cells 8 in the state in which the pipe 11 is not inserted into the cylinder 10. The springs 10' maintain the non-pressing state to the fuel rods F at this time. The springs 10' are expanded outward and the peripheral face parts of the fuel rods F are pressed when the pipe 11 is inserted into the cylinder 10. The fuel rods F inserted into the respective cells 8 are thus stably held by means of dimples 9 and the springs 10' into the positions defined by the outside diameter of the pipe 11.
