At least some parts of the country called USA are trying to do so with SMRs, but seem to be almost stuck in regulations, nonetheless moving slowly forward. Furthermore they seem to be upgrading older reactors, and getting them new, supposedly better and safer fuel(from Framatome). I wondered why I can't seem to recall reading anything about them and that.
