Abstract :
Unirradiated MOX fuel particles with a few millimeters in size were reduced to a U–Pu alloy by electro-chemical means. The reaction started at the grain-boundary and formed metallic coral-like frames. The Pu-concentration in the alloy was measured to be lower than that in the original MOX. Pu-spots were observed in regions that were originally at the site of MOX-agglomerates. These facts indicated that U was reduced prior to Pu during electro-chemical reduction.
