A complex approach based on the consistent modeling of neutron-physics processes and processes of cascade separation of isotopes is applied for analyzing physical problems of the multiple usage of reprocessed uranium in the fuel cycle of light water reactors. A number of scenarios of multiple recycling of reprocessed uranium in light water reactors are considered. In the process, an excess absorption of neutrons by the 236U isotope is compensated by re-enrichment in the 235U isotope. Specific consumptions of natural uranium for re-enrichment of the reprocessed uranium depending on the content of the 232U isotope are obtained.
