World's largest nuclear power plants

Nearly two months after Japan's nuclear crisis began, the head of Tokyo Electric Power (TEPCO) has finally stepped down and the company posted a $15 billion loss for the year. New details have also emerged, showing three of the reactors at the Fukushima plant likely suffered partial meltdowns.

The disaster in Japan has major implications for the US, the world's largest producer of nuclear energy, especially since the crippled Fukushima plant shares the same design as other plants in the US

In the East, China is on the verge of becoming a major player in the nuclear field with about 27 plants currently under construction. In all, there are 442 nuclear power stations in the world and 16 countries currently have 65 plants under construction.

We've put together a list of the world's largest nuclear stations by output capacity. Our rankings are based on the International Atomic Energy Agency's (IAEA) data on megawatts per hour (MWh) produced by active nuclear reactors in 2010.
