RyabkovA new approach to simulation of interphase equilibrium at extraction of actinides in various valent states, some fission products, and admixed acids from nitric acid media in the presence of salting out agents by diluted TBP has been developed. It is based on a set of simultaneous chemical reactions, including salvation, hydrolysis, complexing, etc., characterized by apparent concentration constants. A software package was created for simulation of spent fuel component distribution in multistage countercurrent extraction processes.
