We applied laser-induced breakdown spectroscopy (LIBS) analysis to the molten alloy production process, in which simulated metals (Zr, Cu, Sm, Ce) are used instead of nuclear metallic fuels containing minor actinide (MA). Our aim is in-situ monitoring of the elementary composition of a molten alloy’s surface in a chamber and the vapor particles generated from that surface. We successfully observed the variation in the ratio of the elementary composition of the molten alloy’s surface in the crucible by depending on the crucible’s temperature. The elementary composition of the vapor particles in the molten alloy chamber was also measured. Practical experimental results show that the LIBS technique is very useful for investigating elementary composition in the molten alloy production process and understanding molten alloy behavior in crucibles.
