Abstract

We characterized, for the first time, submicro- and nanosized fission product-alloy particles that were extracted nondestructively from spent nuclear fuel, in terms of noble metal (Mo-Ru-Tc-Rh-Pd-Te) composition, atomic level homogeneity and lattice parameters. The evidences obtained in this work contribute to an improved understanding of the redox chemistry of radionuclides in nuclear waste repository environments and, in particular, of the catalytic properties of these unique metal alloy particles.

Funding

The experimental work and a part of manuscript writing were done at Studsvik Nuclear AB, Sweden, coordinated and supported by Swedish Nuclear Fuel and Waste Management Co. (SKB) under R & D Project 14938. Part of manuscript writing was done during D.Cui’s visiting stay at JRC-ITU, European Commission. The EXAFS characterization performed at Argonne National Laboratory, USA, was supported by the United States Department of Energy (DOE) (DE-AC02-06CH11357). Thanks to H. Bergqvist, W. Sahle and M. Kallberg for microscope analysis and to J. Low for solution analysis.
