This patent describes a debris screen for a fuel assembly for a reactor to which coolant fluid is supplied. It comprises a substantially planar plate member of material impervious to fluid having an array of coolant openings extending through the plate member dimensioned to trap at least a portion of debris particles carried by the coolant; and a skirt member enclosing the periphery of the plate member; each the coolant flow opening having a coolant entry region at a lower surface of the plate member, a coolant exit region at an upper surface of the plate member and a coolant flow path extending between the entry and exit regions, the flow path including an intermediate segment laterally offset from the entry and exit regions to cause coolant to change direction of flow in the intermediate segment and thereby prevent at least a portion of the debris particles from passing through the plate member.
