Ural Federal University (UrFU), Ekaterinburg, Russia aut Purification and Enrichment of Regenerated Uranium in a Double Cascade [Elektronische Daten] [V. Palkin] The effi ciency of two cascades is investigated on the basis of a computational experiment: in the fi rst one regenerated uranium is purifi ed and in the second one low-enrichment uranium is produced from the purifi ed waste of the fi rst one. It is shown that the use of R cascades for purifi cation makes it possible to reduce the content of 232,234U considerably, but it leads to high 235U concentration 60-90% in the steps. To eliminate this, the purifi cation by removal of 232,234U should be done in optimal cascades, calculated according to the data obtained with the R cascades, with the feed shifted into the product step. This makes it possible to reduce the 235U content in the steps of the cascade to 20% or less. The quality of the lowenrichment uranium produced from the purifi ed regenerated uranium can be improved by using dilution and enrichment operations, which make it possible to reduce the 236U content.
