摘要

The study addresses the problems of reprocessed uranium re-enrichment. It is shown that, in the most general formulation, the problem of reprocessed uranium re-enrichment that meets all the requirements on the content of even isotopes and the conditions of spending a given amount of initial reprocessed uranium for production of unit mass of the product cannot be solved in a three-flow cascade of centrifuges or in the simplest versions of double cascades. The possibility of solving the formulated problem in a modified double cascade scheme with a low-enriched uranium (LEU) diluter is demonstrated. The results of numerical experiments showed that it is possible to obtain marketable LEU in the studied version of the double cascade after spending a given amount of reprocessed uranium and meeting different constraints on U-232 concentration in the product, including even stricter constraints than those currently accepted at separation plants.
