Characterisation of secondary products of uranium-aluminium material test reactor fuel element corrosion in repository-relevant brine

Corrosion experiments with non-irradiated uranium-aluminium fuel elements were performed in MgCl2-rich brine. Distribution analysis of corroded material showed that about 90% of the initially available metallic U and Al precipitated. Investigations of these secondary corrosion products provided that one component is a Mg-Al-Cl-hydrotalcite. (C) 2003 Published by Elsevier B.V
