There's a political issue. Just look at how hard it's been to protest all the new gas plants that came up over the last ~20 years. The reason is that we built many small gas plants, instead of a handful of large ones. It divided up the protesters to the point where they couldn't work together.
When we built less, but larger, nuclear power plants, they're easier to protest. If we can make SMRs economical, it makes it significantly harder to protest.
