Abstract

PURPOSE: To uniformize the output distribution of axial direction of a fuel assembly, by means of making a density or a volume of pellets belonging to a lower or a middle zone of the fuel assembly to smaller than that of the pellets belonging to the other part.
CONSTITUTION: Fuel rods 31 constituting a fuel assembly are divided at the position of about 1/4W1/2 height of the height of the core from the low part to the axial direction, and are made into the fuel pellets 32 to be inserted into the upper zone ( for example, having 95% of the theoretical density ) smaller in the density of the pellets to be inserted into the lower part ( for example, 85% of the theoretical density ). Instead of making the density of pellets 33 into small ones, the volume may be small by making the pellet 33 to an empty cylinder or a dish pellet with a chanfer
