摘要： A nuclear fuel assembly has a plurality of fuel rods and a lower tie plate supporting their lower ends. Coolant apertures extending through the lower tie plate. A channel box surrounds the fuel rods and receives the lower tie plate, to confine the coolant. To restrict leakage of coolant between the tie plate and the channel box, the coolant apertures include, adjacent the periphery of the lower tie plate, a plurality of peripheral apertures which are located at least partly outside the outermost fuel rods. The peripheral apertures each provide a coolant velocity peak located further from the axial center line of the tie plate than the axial center lines of the closest neighboring fuel rods. The invention also provides venturis in the leakage path between the channel box and the tie plate, to restrict deformation of the tie plate.

摘要： A radiator with a fan is arranged at a forward tilt under the footrest floor part of a cab floor of a cab-over-engine vehicle. The fan confronts the front of the engine. The fan is connected with the radiator through an air duct, a central axis of the air duct rises rearwardly. The fan has at its center a boss shaped into a truncated cone, the extremity of each of the blades in its longitudinal direction being parallel to the axis of the boss. The air duct has one opening end shaped into a cylinder which partially covers the blades of the fan.
