The FLEX reactor - the next step in molten salt reactor evolution

Landon outlines the work being done by Moltex Flex to make FLEX reactor, which is the latest application of the company's platform stable salt reactor design. The FLEX reactor is the thermal spectrum version of Moltex Energy Limited's globally patented SSR technology - it uses graphite as the moderator. The SSR technology is shared with MoltexFLEX's sister company, Moltex Energy Canada, which is developing the fast spectrum version (the SSR-W) and the WAste To Stable Salt (WATSS) process that will produce the fuel for the reactor from recycled spent fuel. SSRs are fundamentally unique in comparison with all other molten salt reactors in that they restrict the radioactive fuel salt to tubes similar to the fuel assemblies in conventional reactors. A separate, non-radioactive molten salt then transfers heat from the reactor core to heat exchangers.
