Abstract

Growth of electricity demand is rapidly increasing. Several method to supply electricity such as utilizing renewable energy has been used. Nuclear energy is still the best choice to produce electricity. Instead of using uranium as a fuel, utilization of thorium as a nuclear power plant fuel has been investigated since 1950. Thorium is much safer than uranium since it does not produce hazardous by product which can be used as an explosive material. Thorium can be found widely in Indonesia together with uranium and many other rare earth material such as lanthanides group. Separation is needed before thorium can be used as a fuel. In this article, preliminary study of thorium separation from monazite mineral has been conducted. The end product of this study is a plant design for thorium separation process. This study used secondary data which has been lab scale experimental. The data was then predicted by using mathematical model, calculated data were then compared to the experimental data. The model used in this study was in accordance with the experimental data, where R2 for thorium, uranium and rare earth element are 0.9591, 0.7591 and 0.9889 respectively. The developed model in this study then can be used for thorium separation process modelling using METSIM.
