The US unfortunately has almost built no standardized / modular reactors. Everyone was custom. That is why they were so expansive to build.
SNUPPS and the AP-1000 are the only "standardized" nuclear power plant designs built in the US and there were only a small number of them built. Not enough to benefit from economies of scale benefits through standardization and modularization.
