- Title
Purification and Enrichment of Regenerated Uranium in a Double Cascade.

- Abstract
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 U considerably, but it leads to high U concentration 60-90% in the steps. To eliminate this, the purifi cation by removal of U 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 U 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 U content.
