I'll close by pointing out that half or more of the costs you are referring to are driven by hysterical faux-environmentalists and oil lobbyists (the other half is more or less related to poor logistics, which is also fixable, but a different problem). If subjected to the same level of scrutiny and regulation as fossil fuels and renewables, then the costs would come down significantly. That would likely lead to more productions, scale and thus even lower costs.
Nuclear energy was going to be too cheap to meter until the Merchants of Fear got their hands on it.
If nuclear were subject to the same level of scrutiny as ordinary industries we'd have a long stream of nuclear accidents. But these accidents are extremely expensive. Your argument there boils down to a whine that nuclear isn't being allowed to learn via large numbers of meltdowns.
You will also always have regulation and oversight due to proliferation concerns. And without regulations, you're also not going to get a liability cap. Is anyone going to build a reactor if an accident costs more than their company is worth? Fukushima is estimated to cost $700 B. Maybe you're also advocating people not be allowed to sue for damage from nuclear accidents?
Maybe you meant "nuclear is fine if we just assume nothing will go wrong so we don't have to bother with containment buildings and the like."
