> We can roughly break the costs of operating any power plant into three categories: fuel costs, operation and maintenance costs, and capital costs

The article forgets to mention another cost: The cost of disposing/storing used up fuel. This is often forgotten, but a major cost too, if the spent fuel is to be stored safely and securely. And it needs to be stored like that for hundreds of thousands of years!

Switzerland is currently in the process of building a national waste storing facility, a quick Google search showed that the US currently does not have one.
