In general I oppose subsidies, but I think it's a good idea here. Nuclear solves some major problems with other types of clean energy - it's just prohibitively expensive. I'm all for exploring all alternatives to fossil fuels in parallel - I think the seriousness of the climate situation warrants it.

But that cost is largely a function of strong regulations and lack of innovation. If the government gets the ball rolling with subsidies it might get to the point where it doesn't need them anymore. Reducing regulation where appropriate could help too - but in general there are risks and regulation is warranted.

And because it makes so much sense - implement a carbon tax that ramps up slowly to the full cost of the externalities of fossil fuels. It's the most effective thing to fight climate change, but instead of doing that we actually subsidize fossil fuels?!? I don't get it.
