Abstract Scope |
Corrosion in molten salts that operate at 400 to 900oC is of importance to development of nuclear reactors that employ molten salts as coolants, fuels, and tritium breeding blankets. One mechanism of corrosion is preferential removal of one of the alloying elements as a consequence of oxidation of the element by oxidants present in the salt. In a non-isothermal flowing salt-loop. This type of corrosion leads to thermal-gradient driven corrosion, where material consumption occurs at in the heating sections and material deposition occurs in the cooling sections, possibly leading to degradation of mechanical properties at one end and flow constriction or flow blockages at the other end. This talk will provide a discuss of the role that surface structure and surface chemistry can play on material performance in molten salt system, looking towards how nano-structured materials could be of relevance to corrosion control in high temperature molten salts. |
