Study on Oxygen Partial Pressure Dependence and Kinetic of Oxidation and Vaporization Behavior of Insoluble Residues (Noble Metal Precipitation) in High-Level Waste
Year: 2025
Type: article
Abstract: Noble metal precipitates (Mo, Ru, Rh, Pd, and Tc) contained in high-level radioactive liquid waste can affect the vitrification process in various ways, such as formation of yellow phase and deposition at the bottom of the glass melter.Therefore, in this study, thermogravimetric analysis was conducted to investigate the composition and oxygen partial pressure dependence of reactions such as oxidation and evaporation of alloying elements by weight change during heating.
