The (U,Pu)O 2 matrix behavior of an irradiated MIMAS-type (MIcronized MASter blend) MOX fuel, under radiolytic oxidation in aerated pure water at pH 5–5.5 was studied by combining chemical and radiochemical analyses of the alteration solution with

The behaviour of nuclear glass subjected to the stress loading expected in a repository must be investigated to demonstrate that it is capable of durably confining radioactive elements. Because of the minor actinides (Np, Am, Cm) contained in the gla

To assess the impact of alpha radiolysis of water on the oxidative dissolution of UO2 under anoxic conditions, two series of plutonium-doped samples (specific alpha activity 385 and 18 ) were fabricated, characterized and leached in water of varying
