摘要

PROBLEM TO BE SOLVED: To provide a fuel supporting attachment capable of preventing passing of a linear/strip foreign matter included in a coolant while minimizing the pressure loss. SOLUTION: The fuel supporting attachment 60 for supporting a fuel assembly 50 for nuclear reactor including a plurality of fuel rods 51 and an upper tie plate 51 and a lower tie plate 52 supporting the upper and lower ends of the fuel rods 51 comprises a filter 20a catching a solid foreign matter 4 included in the coolant on the inlet side of the fuel assembly 50. A plurality of through holes 3 formed in the filter 20a have a bent portion by which the outlet portion cannot be straightly seen through from the inlet portion. The plurality of through-holes 3 are arranged zigzag in a passage opening surface. COPYRIGHT: (C)2006,JPO&NCIPI
