Someone once told me don’t make the perfect be the enemy of the good.
Also, even worst-case scenario like Chernobyl ultimately wasn't that bad. Several natural disasters in the 2000's have killed way more than it did.
The problem with statements like this is that we don't actually know what a worst case scenario truly looks like. The day before Chernobyl, the worst-cast scenario, by definition, not as bad as Chernobyl. Similarly, the engineers who built Fukishima were aware of tsunamis and earthquakes and built the plant to withstand what was considered the worst case scenario at the time. Then an even worse case scenario happened.
Nuclear is a proven, safe tech that pumps out steady, squeaky-clean energy. People imagine that it’s dangerous because of high-profile accidents but don’t see the daily small catastrophes caused by every other tech.
Nuclear wins, hands down. It’s just such a no-brainer. It’s like we’re back in the days of Edison and Tesla and AC vs DC.
