Dirty power generation, and dirty toxic hazardous industry in general, discriminate against the poor and minorities. That carries an enormous social cost that goes uncounted in discussions like the ones on this thread.
Nuclear discriminates against capitalism. The cost makes the choice of nuclear irrational. The inability to insure nuclear in the private market makes it a travesty of free markets.
The top comment currently on this post is talking about the cost impacts being transferred to the poor and middle class with lots of discussion. I think people are well aware of and discuss the social impacts.
They discuss "social impacts" from the point of view that dirtier power is cheaper, supposedly, hypothetically, net of externalities, while ignoring the cost dirty power inflicts on the people living near the dirty power generation.
