Are you referring to the need for electricity now at the Ukraine plants? Newer technologies such as NuScale require no external electricity for their cooling. The reaction only occurs if there is water and when all the water evaporates then the reaction stops.
> Already economic downturns corelate with fission problems, as plants are not properly maintained. We have one blowing up every thirty years atm. Our reach exceeds our grasp, and there is no shame in admitting to that.
Gas turbines in aviation also blew up way more often in the past than they do now. Who says the blowing up of plants is a constant? There have been many improvements in safety. Also, apart from the Three Mile Island accident, there haven't been major nuclear problems in the US in the last 50 or so years. Furthermore, the thing that lead to the Chernobyl disaster is not possible, by law, in modern reactors. Furthermore, newer reactors require an extra casing of concrete which would also have contained the Chernobyl disaster. You can even fly an airplane in those newer housing buildings and nothing would happen (with the building at least).
