Abstract Scope |
MSR Reactor designs include the use of several types of carbon-based refractory ceramic materials for reactor core components, including use of graphite for the fuel, moderators, and reflectors. It has been shown previously that the interaction of graphite with the structural materials may accelerate the corrosion of structural alloys in molten salts. It has also been demonstrated that the presence of impurities in fluoride molten salts can change the corrosion behaviour of structural alloys in molten salts. However, the effect of impurities in the molten fluoride salts on graphite have rarely been studied so far. This presentation will discuss the stability and behaviour of nuclear graphite in molten FLiNaK salt at 700 oC, and how this behaviour changes with the addition of different impurities such as oxides, metal fluorides, and metallic lithium to the salt. |
