Fuel assembly
专利汇可以提供Fuel assembly专利检索，专利查询，专利分析的服务。并且PURPOSE: To prevent the fuel assembly from curving by constituting a constant number of MOX fuel rods as coupling fuel rods to be fixed to an upper and a lower tie plate and holding other MOX fuel rods and UO
2 fuel rods on the upper and lower tie plates slidably.
CONSTITUTION: Eight of fuel rods which are arranged in the outermost array of MOX fuel rods 32 in a square lattice are coupling fuel rods 35. The upper end parts of the fuel rods 35 are coupled with the upper tie plate 37 with a nut 38 through upper end plugs 36 respectively and the lower end parts are fixed by screwing to the lower tie plate 40 through the lower end plugs 39. The remaining fuel rods 32 other than the fuel rods 35 and UO
2 fuel rods 33 are all regarded as standard fuel rods 41. Those fuel rods 41 and a water rod are inserted into the tie plate 37 slidably through the upper end plugs 36 and an expansion spring 43 and also inserted into the lower tie plate 40 through the lower end plugs 39.
