4. Conclusions

The basic thermodynamic properties of lanthanum, neodymium, and uranium in liquid Ga-In and Ga-Al alloys between 723 and 823 K were determined. Low values of the activity coefficients showed strong interaction between lanthanides and the liquid alloys. The values of uranium and lanthanide separation factors showed that the alloys investigated here have considerable advantage compared to liquid cadmium. Analysis of the data obtained showed that Ga-In and Ga-Al alloys are the prospective media for application in partitioning technologies of spent nuclear fuels and nuclear waste treatment.
