Developing a Fundamental Basis for the Characterization, Separation, and Disposal of Plutonium and other Actinides in High Level Radioactive Waste: The Effect of Temperature and Electrolyte Concentrations on Actinide Speciation

PDF Version Also Available for Download.

Description

This research involves establishing a foundation for describing the speciation of Pu and the other actinides in the extremely non-ideal systems found in HLW. We are developing a thermodynamic database of Pu and actinide complexing in alkaline systems, and at elevated temperatures and electrolyte concentrations. Initially, we are using chemical analogs for Pu; later we will conduct experiments using Pu itself. We are investigating complexation by OH-, acetate, oxalate, and ethylenediaminetetraacetate (EDTA4-). In addition, we are complementing our thermodynamic measurements with spectroscopic studies to validate assumptions made concerning speciation and stoichiometry
