* A contrarianism visa vis environmental crusades against nuclear power that presented it's dangers in a distorted fashion.
* How nuclear on paper presents the possibility of limitless energy with little pollution.
* Nuclear is the kind of big-tech solution that appeals to a lot of nerds.
The problem is that nuclear failed independently from environmental crusades even if some of these were successful. Nuclear power requires vast investment and radiation has the problem that it can weaken anything. Meltdowns aren't the apocalypse environmentalists imply but they destroy permanently a huge store of investment and their commonness has tanked nuclear power independently from popular crusades but those with a stake in nuclear like point to "them hippies" to cover their own failures.
