Abstract

Surface examination of sintered UO2 pellets, leached in groundwater at 90°C, have been conducted and the main results are described. They show the presence of a hydrated layer in which the uranium content decreases with leaching time. The oxidation state of uranium seems to remain (IV). The major components of the layer are magnesium and silicon. The growth of the surface layer in mineral water involves a decrease of uranium release in opposition to its continuing increase i n deionized water.
