Abstract EN
Research is in progress to incorporate nuclear waste in new matrices with high structural stability, resistance to thermal shock, and high chemical durability.
Interactions with water are important for materials used as a containment matrix for the radio nuclides.
It is indispensable to improve their chemical durability to limit the possible release of radioactive chemical species, if the glass structure is attacked by corrosion.
By associating high structural stability and high chemical durability, silica glass optimizes the properties of a suitable host matrix.
According to an easy sintering stage, nanoporous glasses such as xerogels, aerogels, and composite gels are alternative ways to synthesize silica glass at relatively low temperatures (≈1,000–1,200°C).
Nuclear wastes exist as aqueous salt solutions and we propose using the open pore structure of the nanoporous glass to enable migration of the solution throughout the solid volume.
The loaded material is then sintered, thereby trapping the radioactive chemical species.
The structure of the sintered materials (glass ceramics) is that of nanocomposites: actinide phases (~100 nm) embedded in a vitreous silica matrix.
Our results showed a large improvement in the chemical durability of glass ceramic over conventional nuclear glass.
