Hm, is that really the case? Nextgen reactors are not just about lowering the cost of U. Or "saving the environment" from waste. Bonuses, sure. Real strength is increasing efficiency, which means: 1) lower buildout costs, 2) faster time to first iphone charged, 3) smaller, safer designs. They're a way around the giganto-plants of the past, on the way to making nuclear power the ubiquitous reliable utility it should be.
I also like to think of U/nuclear as "Civilizational thinking" - it's the only solid power we can trust to stay by us through 10,000s of years, through cataclysims, and planet migrations, and it's ideal (before we find something more abundant, dense, and reliable) to take us from Earth, to a multi-planet, local-cluster exploring species, I think.
