Am(VI) Extraction Final Report: FY17

This report summarizes activities related to hexavalent Am extraction for FY17, in completion of FCR&D Milestone M4FT-16IN0301030211. Activities concentrated on three areas of research: 1) centrifugal contactor hot testing, 2) Am(VI) stability studies, and 3) batch contact solvent extraction experiments related to ruthenium interference in Am oxidation and re-oxidation of previously contacted aqueous phases. Each of these tasks has already been, or will be discussed in detail in its own milestone report, therefore, only a brief summary of each task follows in this report.

Extractant Design by Covalency

This project aims to provide an electronic structure-to-function understanding of extractants for actinide selective separation processes. The research entails a multi-disciplinary approach that integrates chemical syntheses, structural determination, K-edge X-ray Absorption Spectroscopy (XAS), and Density Functional Theory (DFT) calculations. In FY15, the project reached the final stage of testing the extraction performance of a new ligand design and preparing an americium-extractant complex for analysis.
