Abstract
A nuclear reactor of the type in which fissionable material is placed as fuel in the reactor core in such a manner as to provide the most effective utilization of the material, wherein a fuel assembly is divided into three concentric regions around the core center and is loaded with fuel in such a way that if, for convenience, the regions are named the first region, second region and third region, respectively, in the order of distance from the core center, the infinite multiplication factors in these regions will be such that the factor in the third region is smaller than that in the first region and that in the first region is smaller than that in the second region.
