Abstract

A boiling water reactor includes fuel assemblies having a case containing fuel rods which are parallel to walls of the case. Flow subchannels are formed by each four of the fuel rods. At least two and preferably four vanes in the flow subchannels are tapered in a vertical coolant flow direction and are three-dimensionally curved in such a way as to generate a swirl in the coolant flow. It is therefore possible to obtain a relatively high output from the fuel assembly.
