Fission product containment glasses were the first matrices for which long-term behavior studies were undertaken. A substantial body of results has been obtained over the last twenty years, international scientific cooperation programs have been deve

Glass alteration is a complex phenomenon, the kinetics of which result from the convolution of numerous mechanisms, most of which depend not only on the intrinsic glass properties (composition, structure, surface condition, etc.) but also on the envi

This investigation was carried out to assess the protective properties of the alteration film that develops during aqueous alteration of the French SON 68 (R7T7-type) nuclear glass, notably by examining the behavior of some network-forming cations in

Alteration tests with non-radioactive French SON 68 (R7T7-type) nuclear glass in the presence of simulated metal canister corrosion products (CP) or environmental materials (EM) were simulated using the lixiver2 computer code. The code incorporates h

The alteration mechanism and rate of three aluminosilicate glasses were investigated experimentally in aqueous media between 90 and 200°C. In order to assess their containment properties with regard to minor actinides for the purpose of developing n

A calculation code was developed by the Commisariat a l`Energie Atomique to estimate the influence of the major parameters of a geologic repository site on the alteration of a high-level vitrified waste package. The model is based on a first-order ki

Extensive solid-state characterization (AEM/SEM/HRTEM) was completed on six SON68 (inactive R7T7) waste glasses which were altered in the presence of saturated water vapor (200{sup o}C) for 22, 91, 241, 908, 1000, 1013, and 1021 days. The samples wer
