Meltdown proof

Is not possible, with new reactors it becomes very difficult but with the upgraded uranium it is a near zero but not zero.

Liquid fluoride thorium reactors are designed to be meltdown proof. A fusible plug at the bottom of the reactor melts in the event of a power failure or if temperatures exceed a set limit, draining the fuel into an underground tank for safe storage.

And, y'know, it's actually melted from the start.

Like, you could say "accident proof" is impossible, but a meltdown is a very specific thing.
