Open AccessVarious effects of magnetite on international simple glass (ISG) dissolution: implications for the long-term durability of nuclear glasses
Understanding the effect of near-field materials, such as iron corrosion products, on the alteration of vitreous nuclear waste is essential for modeling long-term stability of these waste forms in a geological...

Open AccessOrigin and consequences of silicate glass passivation by surface layers
Silicate glasses are durable materials, but are they sufficiently durable to confine highly radioactive wastes for hundreds of thousands years? Addressing this question requires a thorough understanding of the...

Apparent Solubility Limit of Nuclear Glass
Most nuclear glass alteration models are based on a first-order kinetic law of the general type r = r 0 (1–C si/C*) or r = r 0 (1–Q/K). It is generally assumed that the establishment of quasi steady-state concent...

Insight into silicate-glass corrosion mechanisms
The remarkable chemical durability of silicate glass makes it suitable for a wide range of applications. The slowdown of the aqueous glass corrosion kinetics that is frequently observed at long time is general...

Single Idealized Cracks: A Tool for Understanding Fractured Glass Block Leaching
Within the scope of the long term behaviour of the R7T7 glass, which is the French nuclear glass, leaching and its coupling with transport mechanisms is studied. Experiments carried out on a SON 68 glass (inac...

Long-Term Behavior of Embiez Archaeological Glass: Results after 1800 Years of Alteration in a Marine Environment
An archaeological glass initially fractured and altered for 1800 years in a marine environment is now being examined by the CEA because of its strong morphological similarity to the nuclear glasses used for im...
