The nuclear emergency unfolding in Japan is causing concern worldwide about the potential risks of power plants, radiation and contamination.
Twenty-nine countries generate nuclear power. Half of them—15 to be exact—rely on nuclear energy for 25 percent or more of their electricity.
The places most dependent on nuclear power were part of the USSR, including Armenia and the Ukraine, or part of the Warsaw Pact, including Slovakia, formerly part of Czechoslovakia.
That's because the Soviets saw heavy industry as a sign of economic virility. Nothing is more "major" than nuclear power, according to Mark Fitzpatrick, a Senior Fellow for Non-Proliferation at London’s International Institute for Strategic Studies.
