No, according to the US Energy Information Administration the levelized cost of nuclear has been comparable or less than coal (without the massive negative externalities of coal)

Also:
"not typically included in levelised cost of electricity assessments is the cost of decommissioning a reactor and disposing nuclear waste, says Roula Inglesi-Lotz an energy economist and associate professor at the University of Pretoria. This would further increase the price of nuclear energy. Even when these costs are not included in calculations, the cost of nuclear investment remains high."

Maybe in other countries, but not the US. Every nuclear power plant in the United States is required, by the Nuclear Regulatory Commission as part of its licensing to set aside sufficient funds to decommission the plant when it reaches the end of its useful life.
>...(The USA is an exception, because the cost of decommissioning is included in the price of electricity, per the Nuclear Waste Policy Act),
Also there is a tax on electricity produced by nuclear power in the US to cover eventual long term waste disposal so it is priced into the cost - though ideally this high level waste will eventually be burned in a 4th gen reactor so the volume of waste will be a small fraction of what it would otherwise be.
scroll to the bottom image. Nuclear is the lowest cost along with hydro. If you want to argue against nuclear, you have to find another argument (which shouldn't be too hard).

Note that nuclear isn't getting any better, while other sources are improving every year. Would you rather plonk down a massive capital payment for a very average nuclear plant for the next 50-80 years, or gradually add more and more efficient sources of energy over that same time period?
