Construction began on unit 1 in October 1979, on unit 2 in July 1980, on unit 3 in June 1982 and on unit 4 in September 1983. The units were first connected to the grid between November 1986 and May 1991. On 28 February 2013, two contract workers died and a third was seriously injured when a platform fell inside a reactor building.
