| Abstract Scope |
Understanding the synergistic effects of radiation and corrosion on SiC materials in liquid metals and molten salts is essential before their future deployment in nuclear applications. In this study, we first investigated the corrosion behavior of several types of SiC, including SiC with Al2O3/Y2O3 additives, SiC with Fe/Ti additives, SiC with B additives, and CVD SiC, in molten FLiNaK at 650 °C. Experimental characterizations were employed to study possible corrosion products, complemented by thermodynamic calculations. DFT calculations, including adsorption energy, ELF, Bader charge analysis, and the NEB method, were applied to understand the interactions between the salt and pure SiC, SiC doped with different additives, and atomic vacancies as porosity. Finally, we studied how SiC materials behave under simultaneous 3 MeV proton irradiation and corrosion in liquid metals and molten salts. This study provides insights into the coupling effects of SiC composition, microstructure, and the irradiation /corrosion in these environments. |
