Study on counter current extraction process of high enriched uranium

Abstract

The counter current extraction process of high enriched uranium with critically safe mixer-settler has been studied. The distribution curves of acidity and uranium in stages have been obtained. The results fitted well with test tube extraction cascade experiments. The interface height and the ratio of the contact phases have been determined. The height of liquid surface was lower than the critically safe limit during the operation. The recovery of uranium is greater than 99.9%, and the extraction efficiency of stage in 1 A mixer-settler is better than 85%.
