Extraction of Am(III) and Cm(III) between tri--butyl phosphate solution and molten calcium nitrate hydrate Ca(NO $_{3}$ ) $_{2}$ -H $_{2}$ O was investigated radiochemically. In the range of water content = 3.5-8.0, the distribution ratio was found to increase with the decrease of water activity. The dependence of the distribution ratios on the water activity in the hydrate melt changes at around log $_{rm H2O}$ = -0.4, which corresponds to = 5.0. The extraction behavior of Am(III) and Cm(III) was systematically discussed with the reported data of trivalent lanthanides.
