Aluminosilicate glasses of rare earth {SiO2 –Al2O3 – (CaO) – Y2O3 – La2O3} can be considered like a potential matrix of nuclear waste. This type of glass appears to be suitable matrix for the specific immobilization of trivalent actinides. Whereas many studies dealt with the macroscopic properties of these matrix (durability, mechanism, etc…), we investigate here the local environment surrounding the nucleus constituting the vitreous network. Thus, we can say that we investigate the local structure of the glass. Aluminosilicate glasses are constituted with silicon and aluminium tetrahedra. They are more especially based on a mixture of silicon Qn(mAl) and aluminium qn(mSi) units. Up to now, few experiments allow to describe the vitreous net...
