That is, compared to older Gen II designs, more of the components are fabricated off-site before being shipped to the site. Small reactors were common early on in the nuclear era, but forgo the economies of size associated with a large boiler (this is basic physics). #repost 3/5

It's more efficient to make larger reactors, up to the point where they are so large that switching them on or off threatens grid stability. The sweet spot, historically has been 1-1.5 GW. I haven't seen anything to indicate that this has changed. #repost 4/5
