Remember when we stopped developing nuclear power for no reason?

Three Mile Island, Chernobyl and Windscale probably don’t qualify as “no reason “

There was a reason - it was anti-nuclear hysteria fueled (hah) in large part by fossil-fuel interests and environmental groups that treated nuclear power as an existential threat rather than one of the safest, lowest-carbon energy sources available. Thanks to them there have been dozens of millions of lives, at minimum, lost.
