Australian and Chinese researchers have made progress in understanding the mechanical properties of a new class of materials for use in molten salt reactors (MSRs). The Australian Nuclear Science and Technology Organisation (Ansto) said yesterday that NiMo-SiC alloys – prepared from nickel molybdenum metal powders with added silicon carbide particles – have superior corrosion resistance and radiation damage resistance. Although there are no commercial MSRs in operation, there is an MSR and thorium energy research and development program at the Shanghai Institute of Applied Physics (Sinap), with which Antso has a partnership agreement. A number of Ni-MoSiC alloy specimens containing varying amounts of silicon carbide were prepared in Sinap laboratories before being characterised at Antso.
