N2 - Long-term integrated in situ experiments are performed in the HADES underground research facility (Mol, Belgium) to study the coupled reactivity between the different components of an underground repository for vitrified high-level radioactive waste (HLW): glass, compacted clay, and stainless steel containers, at 90 °C and under gamma irradiation. Studies pertaining to the behaviour of silicon, a major element released during glass alteration, are presented here. Data collected from the integrated experiment, from simplified tests, and from modelling are put together, giving complementary information. The integrated experiment is used to investigate overall reactvity, whereas diffusion experiments coupled with modelling focused on the precipitation of silica in clay media.
