If the argument is, in part, about footprint then enough solar and battery capacity to output 300MW around the clock with the same uptime/reliability as a nuclear plant is surely going to cover a lot more ground.

I only bring that up because footprint was a point further up the thread.

There's still a fair amount of site work that has to happen here in the small modular concept, but I think when parts of it happen continuously in a factory you're largely immune from a lot of the jobsite nonsense that happened from contractors milking the job for every dollar they could get, plus economies of scale that you do get in a factory setting (citation: industrial revolution).
