Washington State University, in collaboration with Idaho National Laboratory and CEA-Marcoule in France, proposes to develop improved approaches to characterizing and controlling zirconium (Zr) chemistry in streamlined actinide recycling streams by determining thermodynamic data for Zr and Hafnium (Hf) ligand complexation, and characterize the molecular scale impacts of diluents and phase modifiers, by which some of the metal complexation studies will consider Zr4+ organic phase complexes.
