Superphénix was a commercial 1200 MWe Fast Breeder Reactor, the largest ever built. It operated from 1985 to 1998 when it was finally closed on political grounds. It is now under decommissioning, which is due to end in 2028. On January 2015 an important milestone was reached with the complete removal of the sodium coolant from the reactor vessel.
