Commenting on the United Kingdom's plans to build a new generation of nuclear plants in Somerset, Tokyo Electric Power Company (TEPCO) president Naomi Hirose said that the British nuclear power industry needs to be "prepared for the worst."

"What happened at Fukushima was, yes, a warning to the world," he said.

Following a 9.0 earthquake and tsunami in 2011, the Fukushima plant suffered a triple meltdown and the worst nuclear accident the world had seen since the 1986 Chernobyl meltdown. Nearly three years later, the Fukushima site continues to contaminate Japan's air, land and water, and may even continue to cause health problems as far away as California.
