>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.

You seems to be the pedantic one here: ask anyone in the street "what does it mean to not have much space in a room", they will never answer "having a big room surface but the stuffs in the room are spread so that there is not much space between each things".

Pretending that saying "we don't have much space" and crying like a baby when someone say "well you may not have plenty of 10 miles squares areas, but you can put a 4 miles square large reactor in one of them, and it will be better than having to build 10 1 miles square small reactors", that's being the pedantic one: you cannot complain that normal people understand normally what "we dn't have much space" means.

Yes, but this is not a problem that exists in real life. It helps in some scenarios, but it is not the main practical issues that people have.

> that's the appeal! google and meta aren't looking at them

Google and Meta are not looking at SMR _because they don't have enough space_. This is not true at all: if you look at their projects, they have plenty of space.

They are looking at them because they want to generate a small quantity of electricity for their own usage. They want their own small reactor. But it does not invalidate that these small reactors are less efficient than big reactors: they are just happy to pay 2X dollars for a reactor they fully own than to pay X dollars for the same quantity of energy for a share of a big reactor, because it is more difficult to manage if you have to find partners and make sure everyone is agreeing.
