文摘
- •
Electrochemically characterized LiCl–KCl–CaCl2 (50.5: 44.2: 5.3 mol %) melt by CV, LSV and polarization techniques.
- •
Ca2+ deposits first on tungsten working electrode followed by Li+. Cl− discharges on graphite to liberate chlorine gas.
- •
Surface of UO2 pellet reduced to U in the melt with low carbon contamination of melt.
- •
Slow reduction of UO2 due to slow kinetics and low solubility of oxide ions in the low temperature melt.
