Climate change endangers nuclear plants, scientists warn

WASHINGTON -- A year after a 30-foot tsunami ravaged the Fukushima Daiichi nuclear power plant in Japan, some scientists say regulators underestimate the threat that climate change poses to nuclear power plants in the U.S.

"There are clear lessons learned from the Fukushima disaster, yet our government allows the risks to remain," said Jordan Weaver, a scientist with the Natural Resources Defense Council.

"It doesn't have to take an earthquake and a tsunami to trigger a severe nuclear meltdown. In addition to human error and hostile acts, more common occurrences like hurricanes, tornadoes and flooding -- all of which took place around the country last year -- could cause the same type of power failure in U.S. plants."

Nuclear reactor facilities, which need a reliable source of water for cooling purposes, are usually located near the ocean or alongside a large lake or river. There are 104 nuclear reactors at 65 sites across the U.S., nine of them located within 2 miles of the coast. That's a somewhat fraught positioning from the lens of climate science, particularly since the Intergovernmental Panel on Climate Change report from 2007 found that ocean levels are rising roughly 1.2 inches each decade, with some scientists predicting that water levels could rise by as much as a meter by the end of the century.

That may not sound like much, with most nuclear power plants a full 20 to 30 feet above sea level, but each additional inch of water increases the risk of flooding and heightens storm surges, two of the more significant threats of a warmer planet.

What's more, recent reports show accelerated glacial melt, indicating sea levels will rise more dramatically than previously predicted. The Arctic ice study by the International Arctic Monitoring and Assessment Program found that sea levels could rise 35 to 63 inches by 2100, far more than the 7 to 23 inches predicted by the IPCC in 2007.
