Abstract
A fuel assembly for a boiling water reactor includes a cluster of mutually parallel fuel rods. A fuel assembly channel laterally surrounds the cluster of fuel rods and has open upper and lower ends. A top plate covers the upper open end of the fuel assembly channel and has coolant outlets formed therein. A foot part is assembled from a plurality of individual parts and includes a cast transitional piece having a lower end with an inlet opening formed therein and an upper edge inserted into the open lower end of the fuel assembly channel. The transitional piece defines and surrounds a flow channel widening upward in funnel-like fashion from the inlet opening. The foot part also includes a base plate being disposed at and welded to the upper edge of the transitional piece. The base plate covers the open lower end of the fuel assembly channel and has coolant inlets formed therein. A foot part for a fuel assembly of a boiling water reactor includes a transitional piece defining and surrounding a flow channel widening in funnel-like fashion upward along a center axis. The transitional piece has a lower end with at least one inlet opening formed therein and an upper end with an edge. A o…
