Aren’t SMRs essentially unproven? I think only Russia and China built some working facilities, and the rest is still under construction.

I mean anything could happen but seems like a long shot

They are, but if the country has a law forbidding you from doing anything, things cannot move forward. If they'll not work, of course they won't be built. And large classic reactors are unlikely to be built either, even with this new law.

Gotcha - yea I think it’s a good idea to try out these things. I just hope it doesn’t become a ideological fight to make something work at any cost to fit a certain narrative (same goes for renewables of course)
