Nuclear power plants, world-wide

scroll

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.

On 1 April 2008 in 31 countries 439 nuclear power plant units with an installed electric net capacity of about 372 GW were in operation world-wide.

As of end 2005 he total electricity production since 1951 amounts to 52,470 billion kWh. The cumulative operating experience amounted to 12 193 years by the end of 2005.
