摘　　要：采用多级临界安全混合澄清槽，进行了高加浓铀连续逆流萃取运行的实验研究，得到的各级铀酸分布曲线与试管串级的实验结果相符合。测定了界面高度与接触相比。运行过程中，液面高度小于临界安全限定值。铀的回收率＞９９．９％，ｌＡ槽的级效率＞８５％。The counter current extraction process of high enriched uranium with critically nuclear safemixer-settler has been studied. The distribution curves of acidity and uranium have been ob-tained.The results fit these of test tube extraction cascade experiments well.The interface heightand the ratio of the contract phases have been examined.The height of the liquid surface lowerthan the critically nuclear safe limit.The rate of recovery of uranium is more than 99.9%. Theextraction efficiency of stage is more than 85%.
