Structure and Bonding in Actinide Oxides
EMSL Project ID
28693
Abstract
We are studying structure and bonding in actinide oxides, which are critical materials in nuclear fuels, actinide corrosion, actinide waste forms and storage, actinide environmental chemistry, and synthesis and fabrication of other actinide-containing materials. We are specifically interested in performing speciation sensitive probes such as Raman spectroscopy and possibly NMR (or any other appropriate methods suggested by EMSL staff) to determining the local speciation and in particular whether U(VI) oxo groups occur in the UO(2+x) system, since we have good evidence for these by XAFS that contradicts the crystal structures. We are requesting the use of EMSL resources by submitting our existing proposal for beamtime at SSRL and will attach the reviews that this proposal received to assist in evaluation by EMSL.
