Nuclear power plants, world-wide

On December 20, 1951, at the Experimental Breeder Reactor EBR-I in Arco, Idaho, USA, for the first time electricity - illuminating four light bulbs - was produced by nuclear energy. EBR-I was not designed to produce electricity but to validate the breeder reactor concept.

On June 26, 1954, at Obninsk, Russia, the nuclear power plant APS-1 with a net electrical output of 5 MW was connected to the power grid, the world's first nuclear power plant that generated electricity for commercial use. On August 27, 1956 the first commercial nuclear power plant, Calder Hall 1, Eng-land, with a net electrical output of 50 MW was connected to the national grid.

As of 30 June 2009 in 31 countries 436 nuclear power plant units with an installed electric net capacity of about 370 GW are in operation and 48 plants with an installed capacity of 42 GW are in 15 countries under construction.

As of end 2007 the total electricity production since 1951 amounts to 59,450 billion kWh. The cumulative operating experience amounted to 12,750 years by the end of 2007.
