Abstract
Abstract This study evaluates the potential benefits of closing the fuel cycle of WWER reactors by reprocessing spent nuclear fuel (SNF) and utilizing MOX (Mixed Oxide) fuel for multiple irradiation cycles. The analysis quantifies reductions in natural uranium consumption and the volume of spent nuclear fuel through modeling the fraction of MOX fuel assemblies in the core and its impact on isotopic composition and neutron economy. Key equations are presented alongside results derived using computational tools.
