摘要

本文探讨了在两套气体离心机级联中从 232、234、236U 中提纯后处理六氟化铀的特点，并向级联的产品级联添加了废六氟化铀进料流。在级数较多的长级联中，第一级级联中 236U 的有效净化是在 235U 浓度低于 20% 的情况下进行的。确定了能显著降低废物中 232、234U 浓度的第二级级联参数。由于用废六氟化铀进行了还原，该流程可确保生产出符合 ASTM C996-20 工业六氟化铀浓缩规范要求的商业低浓缩产品。

Two-cascade scheme of gas centrifuges for the purification of reprocessed uranium hexafluoride from 232, 234, 236U

The paper considers features of purification the reprocessed uranium hexafluoride from ^{232, 234, 236}U in two cascades of gas centrifuges with additional feeding streams of waste uranium hexafluoride to the product stages of the cascades. The effective purification from ²³⁶U in the first cascade is carried out at a ²³⁵U concentration of less than 20% in long cascades having a large number of stages. The parameters of the second cascade that significantly reduce the concentration of ^{232, 234}U in the wastes were determined. As a result of the reduction with waste uranium hexafluoride, this stream ensures a commercial low-enriched product to meet the requirements of the ASTM C996-20 specification established for enriched industrial uranium hexafluoride.
