I really don't understand that special snowflake thing.
From time to time I ride my bicycle along the levees of the Elbe river from Hamburg to Brunsbüttel. There are two NPP's on the way(now shut down, or in the process of being so. One on the other side of the river, Stade already is.).
Anyways, one called 'Brokdorf' irritated me. Why? Because it looks exactly like that thing in Iran called 'Busher' which I've seen in the media!
Why is that? Because Siemens built it there in license from whomever. Only the painting of the heavy lift shaft on the side of the reactor is different.
While there may be many differences in the details of the implementation inside I feel this special snowflake thing is an unnecessary complication.
Because viewed from afar there are maybe two to three dozen common types cookie cutted all over the world.
Should be possible for the insides also.
Just saying.
