I'm familiar with the closed city system, but to say the majority of scientists swept up in the purge ended up in this is laughable. But if you know about those, you have to know that the NKVD was dumping reams of stolen documents from the west on their desks and telling them to copy the designs.Hell the RBMK of Chernobyl fame was based on documents stolen concerning Chicago Pile-1. That your defense is to say that many scientists in the middle of the century in the USSR were merely doing science in slave colonies is telling.
