摘要
在实验数据基础上推导了Th(NO_3)_4—UO_2(NO_3)_2—HNO_3—H_2O/30％TBP-煤油体系分配数据的数学模型,建立了钍、铀分离净化工艺过程串级实验的计算模拟程序,对工艺参数进行了计算机优化。得到的钍、铀共去污段的各级分布数据的计算值与实验结果符合得较好,平均相对误差在±10％以内。
The mathematical model of distribution coefficients for the systems Th(NO_3)_4-UO_2(NO_3)_2-HNO_3/30％TBP-Kerosene has been derived. The computer program that calculates extraction cascade has been given. Optimum parameters of reprocessing Th-U fuel have been obtained. Comparison between the calculated values and the experimental values of Th, U, HNO_3 profiles in extraction cascade(1A)shows that the agreement for values is fairly good, the mean relative deviation being<±10％.
