As I implied above, it's a problem in particular jurisdictions, not necessarily everywhere. China for one is aggressively pro-nuclear. If thorium reactors are everything their advocates think they are, countries that throw too many obstacles in their path will disadvantage their economies.

Aside from that, nuclear reactors don't necessarily have to be gigawatt-size. Even in the U.S., smaller reactors are starting to make some regulatory headway.

But even conventional 1GW reactors don't have to take decades to build. China's first AP-1000s at Sanmen are being finished up this year and next for a construction time of five years.

China matters, and it can bypass procedural democracy. Large, slow-to-deploy nuclear still has to compete with quick-deploying, cost-decreasing solar and wind (and serious efficiency measures) while it is on the costs-rising-due-to-learning part of its rollout curve. Procedural democracy will not allow new nuclear of any kind in most of the rich democracies. We need everything, but solar PV, wind, and efficiency are the low-hanging fruit.

I agree we should pursue it all. Solar is rolling out pretty quickly right now. It's later, when we want to get past using fossil to compensate for intermittency, that nuclear will be especially important...and it would be good to be past that learning curve by then.
