such calculation often omit the externalized costs of nuclear energy. A study by the French government concluded that a Fukushima style disaster would cost them €430bn, which is more than plant operators and insurance companies can pay, meaning the state will have to cover it.

The ecological/social/health impacts of uranium mining and the somewhat unsolved problem of waste disposal have to be considered as well.

> somewhat unsolved problem of waste disposal
This is the whole high-level nuclear waste for the last 50 years of Swiss nuclear industry. There's a guy standing in the middle. How is that "unsolved" exactly?
"Few thousands"? Do you even realize that 95% of used nuclear fuel is being recycled back into nuclear fuel, and what is left is absolutely tiny amounts? And these tiny amounts lose 95% of their radiotoxicity after just 100 years? This is simple physics, but Greenpeace will never tell you that.
