SNR-300
The Fast Breeder sodium coolednuclear reactor SNR-300 was built near the town of Kalkar, North Rhine-Westphalia, Germany. It was completed but never taken online. SNR-300 was to output 327 megawatts. The project cost about 7 billion Deutsche Mark (about 3.5 billion euros or over 4 billion USD). Klaus Traube, then director of the executing company Interatom, is today one of the most prominent German opponents of the usage of nuclear power.
In late 1972, Germany, Belgium and the Netherlands charged the Siemens subsidiary Interatom to build a fast breeder - still a very new technology at the time. The German government wanted to limit energy import, and, as the uranium supply in Germany was limited, a breeder facility to use the limited resources efficiently was required. The building commenced at the end of the same year.
Bundeskanzler (chancellor) at that time was Willy Brandt (SPD); head of the Bundesministerium für Wirtschaft und Technologie were Karl Schiller (until 7. July 1972) and Helmut Schmidt (until the end of the cabinet (15. Dezember 1972).
In France, CEA and EDF had started to build Phénix in 1968; it powered up in December 1973. It was a pool-type liquid-metal fast breeder reactor cooled with liquid sodium and a small-scale (gross 264/net 233 MWe) prototype fast breeder reactor, located at the Marcoule nuclear site, near Orange, France.
