END CAP FOR FUEL NOSE ASSEMBLY FOR REFRIGERANT FLUID FLOW AND CORRESPONDING ASSEMBLY

摘要

An end unit (7), which has a grid (31) to receive and support the lower ends of fuel rods (3), has tips (39) that are shaped to guide the flow of reactor coolant fluid along the ends of adjacent fuel rods. The guide tips are located in line with the ends of the fuel rods and/or at least some of the connectors (11) of the fuel assembly supporting cage, and some of the tips can form part of the fixing system between the assembly end unit and the connectors.
