The Fermi reactor near Detriot was not a Molten Salt Reactor.

Wrong.

In October 1966, a piece of zirconium cladding inside the reactor chamber came loose. The metal blocked liquid sodium coolant from reaching two of the reactor's 103 subassemblies, each holding multiple fuel rods.

This was not a salt/fuel mix reactor though. But a solid rodded reactor with molten sodium cooling. Losing the coolant handling capability meant China, not a controlled meltdown/drainoff like is being described for this design.

(News flash: sodium isn’t salt. It’s a metal that easily reacts to form salts.)

there were two thorium based msr reactors that ran from 1966-1970 under oak ridge auspices.
