The economic expediency of re-enrichment of depleted uranium with the possibility of subsequent disposal of secondary waste is evaluated. Three variants of bringing depleted uranium as a raw material into the production of natural-uranium equivalent and enrichment of uranium product are examined. Methods are proposed for evaluating the expediency of producing a natural-uranium equivalent from depleted uranium under different market conditions and in different operating regimes of the separation cascade as well as methods of evaluating the value of depleted uranium in the production of a natural-uranium equivalent and the production of enriched uranium product. It is shown that an effective method of bringing depleted uranium into enrichment is diversified production of enriched uranium product and not the production of a natural-uranium equivalent.

贫铀浓缩的经济效率

评估了贫铀再浓缩以及随后处置二次废物的可能性的经济权宜之计。研究了将贫铀作为原料用于生产天然铀当量和浓缩铀产品的三种变体。提出了评估在不同市场条件下和分离级联不同运行机制下从贫化铀生产天然铀当量的适宜性的方法，以及评估贫化铀在生产天然铀当量中的价值的方法以及浓缩铀产品的生产。结果表明，将贫铀浓缩的有效方法是浓缩铀产品的多样化生产，而不是生产天然铀当量。
