| Abstract Scope |
Defects are generated in nuclear reactor structural materials when they undergo irradiation, and this phenomenon alters the microstructure and chemical composition, especially at grain boundaries and dislocations. At the same time, heterogeneity in this material could favor the corrosion process when it encounters molten salt coolants. It was observed that the synergic effect of irradiation and a corrosive environment could either enhance or retard the corrosion events. Therefore, it raises an important question about the influence of generated defects on species transport by irradiation and the aftermath in a corrosive environment. The fundamental mechanism can be explored by using molecular beam epitaxy that provides a platform to grow controlled homogenous epitaxial Fe-based films. Consequently, the defects can be induced by irradiation, and then the molten salt effect can be examined through state-of-the-art techniques using transmission electron microscopy and atom probe tomography. |
