Nuclear power isn't flawless, but the fossil alternatives can kill people every single day.
Fukushima killed somewhere on the order of 10 people? That's a level 7 event on an ancient plant, a wind turbine falling over could easily kill that many people if it landed on a bus. This time it can be different, but your black swan argument isn't much different from our fear of flying.
To be fair, several hundred people died due to the Fukushima evacuations. Which doesn't change the result that nuclear power is extremely safe, even coming in under renewables in deaths per terawatt-hour: https://ourworldindata.org/safest-sources-of-energy
