The research project has two major goals: (1) the selective sequestration of lanthanide (Ln) and actinide (An) cations, and technetium species, from tank waste solutions, using radiation-resistant and thermally-stable polyoxometalate anions as complexants, and (2) the conversion of complexed Ln/An/Tc to reduced oxide bronzes (e.g. MxWO3) under relatively mild conditions, and evaluation of the use of such bronzes as waste forms.
