Isn’t molten salt just energy storage? Heat up salt when you have excess of energy, take heat out when you need it. The worst disaster there is just the container melting.
No, there are molten salt thermal batteries, but they aren’t the same as molten salt nuclear reactor. In a nuclear reactor the fissile material is dissolved in the salt for some reason, and the molten salt acts as a moderator or something. Apparently its safe because if the reactor power fails, the salt ‘freezes’ which prevents fission from occurring. Seems like complex extra steps to me but what do I know.

“Can’t have a meltdown when you’ve already melted the fuel” is pretty much the whole idea there.
