>Maybe what you meant to say is not "there is not enough space", but "there is plenty of small space but not a lot of large space"

my bad, i forgot i was on HN where this type of pedantry is the national sport. it sure sucks any tiny little bit of enjoyment one might get out of having a conversation. it's evident from the rest of your comment you knew exactly what i meant.

>First, the idea that, for a domestic power plant, you only have limited space, seems very unrealistic [...] But how is that relevant? In real life, domestic power plant do not have the constraints of being in thigh places

part of the point of SMRs is to be able to have them in space-constrained places where you otherwise cannot build a large facility. that's the appeal! google and meta aren't looking at them so they can power san fransisco or the country with multiple GW. they want to power a datacenter. i can think of other examples of space-constrained places where an SMR is appealing and a traditional facility is impossible, but you've managed to kill any interest i had in having a conversation.
