Abstract

Fuel assembly for boiling water reactors formed of a cluster of fuel rods held by a head piece and a base, respectively, at opposite ends thereof and surrounded by a coolant-flow guiding casing with the aid of a fastening angle includes leaf springs carried by the fastening angle for mutually spacing the fuel assembly from and mutually clamping it with a multiplicity of other fuel assemblies combinable therewith into a reactor core, the leaf springs extending in axial direction of the fuel assembly and having both ends thereof in contact with the fastening angle, one of the ends being rigidly held by the fastening angle, and the other of the ends being slidingly held on the fastening angle.
