From my understanding a lot of the reason for this is it only really makes sense to make large scale reactors; mostly due to approval processes and regulations already in place. There's a massive up front cost no matter the scale of the operation, so it makes most sense to do larger projects vs smaller ones. https://newatlas.com/small-modular-nuclear-reactors/20860/ https://newatlas.com/small-modular-nuclear-reactors/20860/
