• Centrifugal extractor has the shortest contact time and it is to be used for FBR fuel reprocessing for the future. The two liquid phases are separated by centrifugal force in the settler and the light liquid flows out through the inside weir and the heavy liquid through the outside one. And the interface has to be hold to keep stable operation. How-ever, since the observation of the interface was very difficult, the behavior of the interface in the settler was not clearly understood before. In this study, in order to observe the correct diameter of the interface, the experimental equipment is made of transparent plastic and the diameter is determined by taking photos, lighting a flash. As a result, the stability of the interface is examined for various flow rates and rotation velocities. From the data, it is shown that the pressure drops at 1, 800 rpm is proportional to the flow rate at organic weir but is proportional to the power of 0.64 of the flow rate at aqueous weir.
