Of the nuclear plants that provide about a third of Japan’s electricity (see chart), Fukushima Dai-ichi is not the first to be paralysed by an earthquake. But it is the first to be laid low by the technology’s dependence on a ready supply of water for cooling.Well, of course, you have already read this post so you know.
UPDATE: Okay, I'm probably too quick on the draw here. Nuclear reactors and water issues isolated to Japan? Fine. (Although the thrust of the article is certainly to contextualise the role and vulnerabilities of nuclear power on a global scale. In that context, I maintain that including the above sentence without reference to the water-related problems experienced by nuclear plants in Europe the US, is misleading.)
