In March 2011, a devastating earthquake and tsunami set off
a partial meltdown at the Fukushima nuclear plant on Japan's coast. A recent
study led by European researchers found Fukushima is not alone, as 22 other
plants around the world may be similarly susceptible to destructive tsunami
waves, with most of them in east and southeast regions of Asia.
The 23 facilities on the list (including Fukushima) house a
total of 74 nuclear reactors.
