Nuclear power is often touted as a solution to climate change, but Fukushima serves as a warning that far from solving the climate problem, nuclear power may be highly vulnerable to it…nuclear power plants are typically sited near large bodies of water, often seas or estuaries. It is this attachment to water that makes nuclear power vulnerable to climate change (Energy Policy, vol 39, p 318)…Nuclear regulators are already well aware of several safety issues, including flooding, loss of power, loss of communications, blockage of evacuation routes and equipment malfunction. Hurricanes pose the greatest threat….The final problem is droughts, which climate models predict will become longer and larger. Legal battles have already been fought in the US over scarce water resources in regions with nuclear power plants, including the Catawba river basin in the Carolinas and the Apalachicola/Chattahoochee/Flint river basin in Georgia, Florida and Alabama. These battles show us that adapting our systems – including nuclear power – to a reduced supply of water will not be easy…The bottom line is that if nuclear power is to be used to mitigate the effects of climate change, it must also be capable of adapting to them. There are serious doubts that it can.
