I'm a bit on the pro-nuclear side, but if you met a banker and asked him for a couple of billion upfront to build a nuclear plant, and said those things, he'd reject you outright.
If you don't believe the IPCC storyline, nuclear is still best power source right now. But there is no hurry. We can safely dabble with renewables and batteries and such until oil, gas and coal run out. No political hard decisions are needed, because prices of fossil fuels will increase well in advance to any catastrophe. So it will become economically sound to produce energy in some other way. Maybe it won't be nuclear then, I don't really care.
