On May 5, 1955, the Federal Republic of Germany, with the French occupation force, started to work in earnest towards peaceful use of nuclear energy. The district of Bavaria and Baden-Württemberg were particularly interested in this development. In 1957 the "Arbeitsgemeinschaft Kernkraft Stuttgart" (AKS) group was created in Baden-Württemberg. The minister-president and minister of the economics of Baden-Württemberg at the time, Hermann Veit took over the project of establishing a nuclear power plant, and looked towards the Calder Hall Gas cooled reactor in England for a design.
