摘　　要：研究了Purex流程中U/Pu分离段还原剂从一端加入时铀酸分布的稳态计算方法。计算结果与串级实验结果吻合较好。在所选几种工艺条件下,对铀酸分布进行了计算,并根据计算结果对Purex流程中采用水溶性还原剂时U/Pu分离工艺条件进行了分析。The steady-state calculation method for the distribution profiles of uranium and nitric acid in U/Pu separation stage of Purex process, in which hydrophilic agent was used as reductant, was introduced. The calculated results are in good agreement with the experimental results. According to the calculated results of variant flowsheet conditions, the optimization of U/Pu separation flowsheet was analyzed.
