Nope. No nuclear energy supporter will state that nuclear energy is perfectly safe, clean, secure or reliable. Nothing is perfect, why would the bar for nuclear energy be perfection?

Nuclear energy is not perfectly safe for the obvious reason that we've had Three Mile Island, Chernobyl and Fukushima. It is not perfectly clean, since it produces nuclear waste. It is not perfectly secure, just look at the Zaporizhzhia power plant. It is not perfectly realiable: there are times when a lot of French reactors went offline because the water in rivers was too warm.

What exactly is your argument?
