| Abstract Scope |
Our interest in finding suitable waste forms for the effective immobilization of minor actinides in persistent architectures has led us to explore the molten salt synthesis of Am containing materials. We performed DFT calculations to estimate the stability of the target compositions to increase the success rate of our syntheses. Using this information we pursued the crystal growth of americium containing oxides and fluorides in molten salt environments, which has resulted in several new americium containing phases, including K3Am(PO4)2, K3AmSi2O7, and CsAm2F7. We have solved the single crystal structures of these phases as well as synthesized single crystals of their surrogate containing analogs, whose structures we also determined. Furthermore, we conducted radiation damage studies using the surrogate containing phases to learn more about their radiation resistance. These findings will be presented. |
