From the FrumForum (say that three times fast):

First Brad Plumer in the New Republic, then Matt Yglesias on his site have marveled at the supposedly strange enthusiasm of conservatives for nuclear power. What’s strange about it? It’s pure cold economic rationality. If you wish to move away from carbon-emitting electricity sources, nuclear is far and away the cheapest choice. If we’re not going to rely more on nuclear power, then the reduction in carbon emissions will have to imply some dramatic reductions in standards of living.

I think that France has certainly demonstrated the wisdom of nuclear power from an economic perspective. The usual worries remain (waste disposal, Chernobyl, etc) but obviously coal doesn’t jive with liberal environmental goals and other types of energy just aren’t capable of delivering the same amounts of power. I think the conservative perspective is certainly to go with the most efficient form of power. Our natural inclination towards caution should also have us working hard on solutions about how to address the associated concerns.
