Wait, there is more. Nuclear needs water to cool, hot water then goes into rivers. This, until the river becomes too hot for the life in the water, then you cannot use your plant anymore (or you can, at the risk of killing all life in the area). Also water evaporates when it's hot and vapor is a greenhouse gas even worse than carbon dioxyde. This might sound like a minor problem in the short term but it might be a huge issue in the future. Also Uranium is sold at a negative ROI right now because of the decline of demand from Japan and Germany since Fukushima. But as those countries roadmap for nuclear changes, and as China is building more plants, the price for Uranium (which is quite inelastic) will increase significantly. Problem is, you don't build a plant for a year or two, you build it only if you intent to use it for decades. The commitment is huge. I believe nuclear is useful as part of the mix but isn't a one-size-fits-all solution.
