There's no measure by which nuclear energy is the "energy of the future". It's too complex, too expensive and it doesn't scale. SMRs are proving to be a fever dream with ever rising costs and the number of nuclear reactors in operation is decreasing year by year and both Wind and PV are now each producing more electricity than nuclear.
Nuclear has had its moment. That moment is gone.
PWRs are not really that complicated. They are just very hot metal rods inside a thick steel pressure vessel that boil water to make steam.
"Nuclear has had its moment. That moment is gone."
When CO2 caused climate changed is posed to be civilization altering this is a very very foolish thing to say.
