> try to get some of that efficiency back with factory production, but at best it just evens out. It's not just factory production. There's a lot of savings from just scaling down the design. Currently the pressure vessels for a typical large reactor (the AP1000) are build using forges that weigh (take a moment to appreciate the number) 15 thousand tons [1]. No such forges exist in the US. Truth is, NuScale plans to source their pressure vessels from one of the existing vessel manufacturers, the South Korean Doosan [2]. However, it is very likely that their vessel can be produced with much smaller forges, and in time more manufacturers will have the capability to build it.
