Hi Nnadir,
Do you think this might work for fluorides? Copenhagen Atomics are running a non-fission prototype with 700C fluorides (with lithium and uranium, no beryllium, heavy water moderator presumably replaced by light water for now.) They are starting a one year non-stop trial. The reactor has seven high-temp pumps in it, which they have developed and been testing for some time, but five year planned no-maintenance runs at that temperature sounds tricky.
