In this work a solvent comprising of tri-butyl phosphate and bis-triazinyl, bi-pyridine in cyclohexanone has been used in a single centrifugal contactor test to evaluate its GANEX process potential. It was found that the density of the aqueous phase had to be increased to facilitate phase separation in the centrifuge. The kinetics of the system was also found to be relatively slow in the equipment of choice, especially regarding the stripping. However, it was still possible to recover more than 87% of all actinides in one extraction step with minor fission product contaminations using a flowrate of 30 mL/h.
