Nuclear waste is investigated from the aspect of its nanoscale behaviour. Four materials are selected as the nuclear waste container. Using the irradiation-induced amorphisation, some characteristics are examined. The Displacement Per Atom (dpa) is affected by the ion dose using the Stopping and Range of Ions in Matter 2008 (SRIM 2008) code system, which is a computer package of molecular dynamic simulations. The dpa is changed completely and kinetic energy is transferred to the target by the nuclear collision. The length of the material is a function of the ion collisions. It is concluded that a thickness of 204 nm is the optimised length of a waste drum by crystalline silicotitanate.
