>>13420809I know, but I'm just saying that's not what happens. uclear fission is self-propagating, meaning when an atom is split-up and releases a huge amount of energy, it results to another atom splitting up and the cycle goes on. Nuclear reactors do this chain reaction at a controlled rate (instead of blowing up into a mushroom cloud resulting from a continuous, uncontrolled chain reaction). So even when the reactor is "turned off", the fission continues for a period of time, thus the need for continuous cooling. And even after fission, there are huge amounts of "left-over" heat produced and that, too, needs cooling.
So turning it off like that is bad.
