Creys-Malville, fast breeder reactor stopped, France

A fast-breeder reactor, stopped in 1997. A total failure. Demonstrations against it in 1977 were met with repression. Vital Michalon was killed by police.


There was a demonstration with tens of thousands of people (from France, Switzerland, Germany...) on 31st July 1977 against the so-called Superphénix project (a fast-breeder reactor that would work with plutonium and sodium), at Creys-Malville, near Morestel in the department of Isère. The police killed a demonstrator, Vital Michalon, a young professor of physics, by throwing a grenade to him. The project was finally suspended twenty years later. The arrogant name Superphénix comes from the mythical bird Phénix that is reborn from its own ashes, as electricity would be produced from the plutonium which is a waste product of uranium-fuelled nuclear reactors.

Project Details and Actors
Project DetailsThe installed power of the Superphénix would have been 1200 MW. The total investment needed to build and then dismantle the project is of the order of ten billion euros. Dismantling is expected to last until 2017. However, the 14 tons of plutonium and the sodium blocs would still remain at the site.

Do you consider this as a success?Not Sure
Why? Explain briefly.Although the project was stopped, dismantling is still proceeding. There was a heavy price paid for by the opposition to the project.
