So you tell me you don't understand that by design, if the water inside the reactor boils the reaction stops, is foolproof? This means you don't believe in the absoluteness of the laws of physics. Big claim on your part.

When I say that current gen are foolproof, I mean they are humanproof. You would have to literally distort the functional possibilities of physics to have a meaningful accident, or cause a literal cataclysm on the site of the powerplant that would make the underlying nuclear accident a joke in comparison.

The reactors do no rely on valves or other complicated industrial design gor security. They rely on basic geometry and physics. If you don't want to hear that from a lowly internet lurker, i can understand, but refuting an expert on the subject would be much harder; so i invite you to read :
