Thanks for the paper. Quick summary (of a quick read): Most research has studied US and France; this paper adds other countries. Costs have greatly increased in US and France, but not always in other countries. They've decreased recently in South Korea. > (economies of scale) Why do you blame economies of scale? The paper doesn't say that, afaict. Also they say, "increased environmental and safety regulation ... may have led to cost increases", which does not sound conclusive. Also, I think we really need to be talking about lifetime cost, including construction, operation, and decommissioning. In many things, spending more up front reduces later costs.
