この発明によると、隣接する前記第１格子板と隣接する前記第１傾斜板とにより形成される空間である液体流出用の流出路と、隣接する前記第２格子板と隣接する前記第２傾斜板とにより形成される空間である液体流入用の流入路との間に、屈曲板のみで形成されて成る流路、換言すると断面積が冷却水の流入口よりも大きい流路によって圧力損失を低減することができると共に、屈曲板に沿って冷却水を整流することができるので、流通する冷却水の圧力損失が小さい異物捕捉用フィルタを提供することができる。更に、この発明によると、冷却水の流入する部位と流出する部位に第２格子板及び第１格子板と屈曲板とにより断面積の小さい流路が形成されていることによって、冷却水が流入してから流出するまでに２度の異物を捕集する機会が生じるので、異物を確実に捕捉可能であると共に、捕捉された異物が、第１格子板と屈曲板とで形成される第１格子と、第２格子板と屈曲板とで形成される第２格子との間のフィルタ内部に、留まるため、冷却水流を止めた場合あるいはこの異物捕捉用フィルタを装着した燃料集合体を冷却水から引き上げた場合に、屈曲板のみで形成されて成る流路内に捕捉された異物がフィルタ外に脱落することがない。 According to this invention, the outflow path for liquid outflow, which is a space formed by the adjacent first grid plate and the adjacent first inclined plate, and the second inclination adjacent to the adjacent second grid plate Pressure loss is caused by a flow path formed only of a bent plate, in other words, a flow path having a cross-sectional area larger than the cooling water inlet , between the inflow path for liquid inflow, which is a space formed by the plate. Since the cooling water can be rectified along the bent plate, it is possible to provide a foreign matter capturing filter with a small pressure loss of circulating cooling water. Further, according to the present invention, the flow path of small cross-sectional area is formed by the second lattice plate and the first lattice plate and the bent plate at the portion where the cooling water flows in and the portion where the cooling water flows, so that the cooling water flows in. Since there is an opportunity to collect the foreign material twice before it flows out, the foreign material can be reliably captured, and the captured foreign material is formed by the first lattice plate and the bent plate. In order to remain inside the filter between the grid and the second grid formed by the second grid plate and the bent plate, the cooling water flow is stopped or the fuel assembly equipped with this foreign matter trapping filter is When pulled up from the filter, the foreign matter trapped in the flow path formed by only the bent plate does not fall out of the filter.
