Description

The ageing processes of simplified nuclear glasses under β-irradiation have been investigated on zirconium-bearing aluminoborosilicate glasses by micro Raman spectroscopy. No dose rate effect has been detected between 2.103 and 2.104 Gy/s for a 3.107 Gy integrated β dose. Important structural differences appear between the volume and the surface, with an increase of the polymerization and a better defined danburite-like ring structure in the bulk relative to the surface. Molecular O2 is created during glass ageing, mostly close to the sample surface. Both processes indicate an important reorganization of the glassy matrix during β-irradiation
