Extract

Previous investigations have shown that the lanthanide orthophosphates (i.e., analogs of the mineral monazite) are promising candidate waste forms for the storage of high-level actinide or TRU wastes [1]. In the present work, the properties of lanthanide orthophosphates loaded with simulated Savannah River defense wastes and simulated reprocessed light water reactor wastes have been investigated with the goal of evaluating the potential of these materials as advanced primary waste forms.
