Abstract
A fuel bundle for a boiling water reactor contains a plurality of fuel rods, some of which contain a moderating material rather than nuclear fuel or contain nuclear fuel in the lower section of the fuel rod and moderating material in the upper section thereof, for improving both the axial and radial power shapes of the fuel bundle. The moderating material in the upper section of the fuel rods increases the neutron moderation in this section of the bundle, thereby compensating for the poor water moderation of the boiling water in this section, increasing the power generated in this section and flattening the axial power shape of the bundle. Fuel rods in the interior section of the bundle contain moderating material which also flattens the radial power shape. Caps containing moderating material are also placed on the upper end of each fuel rod in order to reflect neutrons thereby reducing the top axial fast-neutron leakage.
