© 2019 Elsevier B.V. Analysis of radionuclides in radioactive waste is performed according to a number of operating protocols which are usually time-consuming and difficult to implement. The use of micro devices for liquid-liquid extraction of radionuclides is promising, since small amounts of materials are needed. In this work, a plug flow modelling approach for the liquid-liquid extraction in microdevices is presented. A multi-component chemical process based on the PUREX-TRUEX waste management treatment is analysed. We evaluate the performance of the coupled micro-units as a function of channel size, superficial mixture velocity, and initial loading. The results show that it is possible to use the model in an optimisation based design procedure for microfluidic devices.
