Atomophobia is a big oil plot tbh

Newer designs are even better. For example, a molten salt reactor can be designed so that it physically can’t go into core meltdown. Because the radioactive fuel is dissolved in a molten salt compound, an overheating reactor can simply melt through a barrier, pour into a shielded chamber, and solidify back into a solid form. 

The best example uses liquid fluoride salt and radioactive thorium, which is cheaper, more plentiful, and less suited to weapons than uranium.
