Fuel enrichment distribution, which refers to the varying concentrations of fissile isotopes (typically Uranium-235) within different regions of the reactor core, has a significant impact on the overall efficiency and performance of a nuclear reactor. A uniform enrichment distribution, where all fuel assemblies have the same enrichment, can lead to a non-uniform power distribution within the core. Fuel assemblies located in the center of the core tend to experience a higher neutron flux and, consequently, generate more power than assemblies located near the perip....
