Seems ironic that in a thread about fusion with loads of difficult technical challenges that will still require decades of research after 60 years of investment and research have already been poured into it, a minor issue of slight corrosion in LFTR requiring maybe a few years of research is seen as an insurmountable obstacle with "no real solution in sight".

The solution may already be here, in the form of ceramics already used in aeronautics. A French startup is working on a small reactor for industrial heat with them.
