Finland is a good point. You guys can't really use a whole lot of solar power, can you?
The trouble with nuclear power is that the expected payoff from R and D is so low. If the payoff from Nuclear R and D is one dollar of improved efficiency for every dollar of investment, the ratio for solar is 1:50. Almost no money has been spent on solar R and D, and yet it's had astounding efficiency returns. By contrast, the dumptrucks of money poured in nuclear (and coal and oil...) have done almost nothing.
