| Research Abstract |
Solubility and activity coefficient of minor actinides(MA) and fission products(FP) in liquid metals were investigated for performance assessment and optimal design of reductive extraction systems for MA recovery. The activity coefficient of some lanthanides was measured by an electrochemical method and compared with literature values to confirm systematic nature of lanthanides. Also, the solubility of lanthanides in mixtures of more than one lanthanide and solvent metal was measured and found to be explained by assuming an ideal mixing behavior of intermetallic compounds in the solid phase. As a result of this study, it became possible to give conditions for solute concentrations in order to achieve high efficiency separation and recovery of MA.
