I think that recent initiative by YC under sam to invest in startups that may herald breakthroughs in sustainable fission is a great start. This should lead to a healthy competition which so far has been missing since it used to be a government only venture for a long time.

YC companies that do relatively tiny hardware projects tend to fail at a rate much higher than their software siblings and the kind of investment required to get a next generation nuclear reactor from the drawingboard to a reality is not usually associated with start-up accelerators.
I know they're funding two start-ups in this domain but I don't believe this is a path that will work out. On the other hand, I've been wrong in the past on other predictions so feel free to ignore me :)
