Oh ok, yeah I think we agree. the original quote I was responding to was "the (false) idea that what was holding back nuclear was perception of safety, rather than cost." I was simply trying to say that safety and cost are not independent. Safety is a massive reason why nuclear costs so much.
NuScale's putative safety improvement came from considerably larger cost. Safety and cost may not necessarily be related, but in NuScale's case they certainly were.
