MOX fuel
SCK•CEN played a key role in developing MOX fuel. In 1960, near the same site, NV Belgonuclaire, a joint venture between SCK•CEN, Electrabel and Tractebel received its first plutonium from the United States, with the goal of industrially producing MOX fuel. In 1963 BR3 was loaded with MOX fuel and was the first reactor in the world to generate electricity this way.
