Abstract

Abstract

In order to simulate the U/Pu separation (1B) process of uranium plutonium redox extraction (PUREX), a mathematical model of 1B process with NH₃OH⁺-N₂H₄(HAN-HYD) as reducing extractant was established based on the framework of MPMS calculation model, using multi-stage mixer-settler as extraction equipment, and based on the chemical reaction system and empirical extraction system. The validity of the model is verified by comparing with the literature data. The mathematical model is applied to explore the effect of a low flow rate and high acid cleaning solution in 1B process under specific parameters. The results show that the introduction of the low flow rate and high acid cleaning solution will reduce the recovery of U/Pu. In order to further evaluate the effect of low flow rate and high acid cleaning solution on the separation efficiency and recovery efficiency of 1B process under different conditions, different U/Pu separation effects were obtained by changing the process parameters of low flow rate and high acid cleaning solution in the model. The calculation results show that the optimal U/Pu separation efficiency can be obtained by 1B process without introducing low flow rate and high acid cleaning solution. The mathematical model will provide useful help for the process evaluation and prediction of 1B process based on multi-stage mixer-settler.
