| Abstract Scope |
The development of reliable high-temperature structural materials will be critical for the successful deployment of molten salt reactors (MSR) into the nuclear fleet. Copenhagen Atomics has identified SiC and carbon matrix-based continuous fibre-reinforced composites as candidate salt-facing materials for its thermal spectrum thorium breeder MSR design. These materials have been selected due to their low neutron absorption capture cross-section, high-temperature strength, pseudo-ductile failure mode and irradiation stability. However, information on their constituent's compatibility with molten FLiNaK salt is highly variable. This makes determining accurate corrosion rates difficult and information on the extent of salt penetration of these materials is also very limited. This talk will present the preliminary findings to start addressing this critical gap in the literature using in-house salt corrosion and permeation testing on off-the-shelf composite materials and report the effects of an over-coat on the aforementioned properties. |
