Abstract
In a foot of a fuel assembly of a boiling water reactor, an upper edge of a transition member is tight against a lower edge of a fuel assembly casing to substantially prevent bypass flow between them. Rather, bypass apertures are provided therefor over all sides of the fuel assembly casing. In a first position of a base plate lying on the transition member, the bypass apertures on some sides are blocked by lateral surfaces of the base plate, while in a second position of the base plate, the bypass apertures of other sides are blocked. The direction of the bypass flow can thus be predetermined regardless of the position of the fuel assembly casing.
