Advanced carbide materials are presently considered in nuclear industry. For example, SiC composites and MAX phases are considered for accident tolerant fuel cladding, coatings and even structural components. Presently, many international efforts are focused in the Horizon 2020 IL TROVATORE project to investigate the radiation tolerance of these classes of materials.
In recent years, computational models have claimed an important role in understanding the mechanisms at work leading to the degradation of materials under irradiation. The phenomenon of radiation in materials is inherently a multi-scale problem: a flux of subatomic particles (neutrons) interacts with lattice atoms leading to the failure of macroscopic components. Given the different length- and time scales involved, multi-scale modelling techniques are used to simulate the damage mechanisms active at the different scales of the radiation process.
