The notion was that “countries that decide to develop their own enrichment capacity will not only occupy a privileged competitive position but also will become part of an oligopoly with obvious political implications.” Nogueira Batista was worried, however, that Germany might not be able to offer Brazil centrifugation technology under existing obligations.
