"ignore the production costs" - what exactly do you think you're paying for when you buy renewables equipment ?
"ignore the environmental cost of the equipment" - the energy paybacks on all renewables techs are now very low. Concrete usage in wind turbines is not comparably significant (perhaps you're thinking of dams?). Yes, some producers of solar cells, mainly in China, have had bad waste management practices (like a lot of Chinese industry in general). But compared to the amount of power produced over the lifespan of the products, it's quite small.
Anyway, once again we see that the issue with nuclear is rarely lives - it's cost. Nuclear accidents tend to be accidents in slow motion. Excluding any pressure explosions or the like, they generally give you plenty of time to get away without profound health consequences. But the down side is that, being in slow motion, they just keep on going and going, and keep on costing money. They may be in slow motion, but they don't let you just ignore them. You can't just stay in an area with, say, contaminated water and keep drinking it as if nothing's wrong. You can't just keep operating a facility that's suffered an accident as if it never happened. You have to remedy them and it always costs a fortune. And the potential upper bounds on the costs are almost unlimited (picture, say, the cost of a worst-case scenario at Indian Point with winds pointed at NYC - the cost of even a couple week evacuation of NYC is almost unthinkable).
The nuclear industry has long suffered from a very unfortunate problem: a negative learning curve. With most technology, the longer you use and produce it, the cheaper it gets per unit. The nuclear industry has been one of the few industry where the costs have risen with time as people learn more problems in their designs and more risks that haven't been taken into account. And often the only way to address them is with brand new generations of reactors. Which is great, except that now you're starting your learning curve over from scratch, and your system is most commonly even more complicated to boot. It's really been a curse to the industry, and until it goes away, a true "nuclear rennaissance" is never going to occur. And no amount of government limitations on liability, no amount of municipalities forcing costs on to consumers, no amount of anything will really get the "take over the market" takeoff that proponents really want to see.
That's of course not the only problem nuclear has had. Another is the very long lead times on projects. The consequence is that you have to guess long in advance what the electricity market is going to be like. France suffered from this - they significantly overestimated what electricity consumption was going to be when they built most of their nuclear plants, leading to a generation capacity glut. This led to a lot of really inefficient uses of electricity and much higher investment costs than were necessary to meet demand.
