b'TALENT PIPELINE: Chemical kinetics were determined for Np(VI) ion complexes of tributyl phosphate, Heather J. Culbertson, student DEHBA, and di-2-ethylhexyl isobutyramide in dodecane using integrated electron at University of Notre Dame pulse irradiation and transient absorption spectroscopy techniques at the Brookhaven Jeffrey R. McLachlan, student at National Laboratory Laser-Electron Accelerator Facility. These experiments probed Florida International University the change in reactivity of the dodecane radical cation with each ligand in the absence and presence of Np(VI) using the radicals absorption at 700 nm. Unlike uranium, Np(VI) ion complexation afforded a significant increase (up to 53 faster) in chemical reactivity for all three ligand complexes relative to their non-complexed state. These findings suggest that the radiolytic lifetime of process ligands are expected to be shorter under envisioned used nuclear fuel reprocessing conditions, although their modification at an electrode surface may instill additional stability.

As the cathodic limit is extended, the wave corresponding to the reoxidation of Np(V) to Np(VI) shifts, possibly due to a change in coordination environment or some other chemical phenomena.
