Abstract: In course of development of a code for high plutonium flowsheets, an improved model of Purex distribution equilibria based on the activity coefficients has been developed. Incidentally, it is observed that this model performed quite satisfactorily even in low aqueous acid concentration range, normally not considered in other popular models of Purex. For In(DH)=f[In(XH)] dependency, discussed by Kolarik in an earlier paper, good agreement among theoretical, predicted and experimental results has been observed. In this paper experimental results of nitric acid extraction for several case studies are compared with predictions from the model.
