Abstract

In a simplified (SiO2, B2O3,Na2O, Al2O3, ZrO2) glass,corresponding to the basic matrix for the French nuclear waste containmentglass, the authors developed a molecular dynamics simulation of the atomdisplacement cascades resulting from a disintegration of the actinides.After simulating the secondary cascades resulting from the first atomsdisplaced by a collision with a recoil nucleus, an actinide (U) was added tothe model and the cascade produced by accelerating this type of atom wasexplicitly investigated, notably to observe the morphological evolution ofthe cascades and the resulting changes in the glass structure.
