I don't think anybody would earnestly argue that anything is "completely safe" because that's not how risk management works.

The exhaust of 250 years of fossil fuel energy production is stored in your lungs and bloodstream. It kills five million people every year. As bad as some of the nuclear accidents have been, it's minuscule compared to what happens on a daily basis in the oil/gas/coal industry.

"10 people being killed by nuclear power is a tragedy. 5 million people being killed by coal mining and burning is a statistic." - Josef Stalin

Agreed, “perfectly safe” is nonsensical. Even wind turbines aren't “perfectly safe” either: https://www.rechargenews.com/wind/daring-rescue-of-enercon-w...
