This study is related to the question of the long%term behaviour of the high%level activity nuclear waste confinement glass. In contact with water, a hydrated amorphous silica layer, known as the “gel” is formed at the glass surface. This gel results from the departure of the most soluble elements and from the mechanisms of hydrolysis and recondensation of the silicate (siloxane ?) bonds. In certain conditions, the gel can limit the exchanges between the glass and the solution. Our hypothesis to explain this phenomenon is the closure of the gel pores. This thesis actually presents an original insight into silicate glass alteration, usually described by chemical thermodynamic considerations, and highlights the impact of morphologic transform...
