Fukushima’s (Non-)Surprises

Fukushima has been back in the headlines of late, with the ‘surprise’ discovery that hundreds of tons of Strontium-laced radioactive water has been leaking into the Pacific, where the processes of bioaccumulation and biomagnification will ensure that it eventually winds up in our sushi. I put scare-quotes around ‘surprise’ because it really wasn’t a much of a shock to people intimately involved with the disaster. Individual leaks might be difficult to spot, but they know how much water they are pumping into the ruined reactor buildings, and they know how much water they are storing. It isn’t a very complicated math problem to figure out how much water is being lost. Especially, one might imagine, to the nearest hundred tons. Seriously, where did people think that water was going exactly?

With all the focus on the leaks though, I worry we have been missing the much (much) bigger dangers the continuing disaster poses. There is still the spent fuel-pool sitting atop unit 4, which is badly damaged and increasingly unstable. Even a relatively modest earthquake (the normal and entirely expected kind) could bring it down. If that happens, which it very well might, it would inevitably lead to a radioactive fire that would dwarf Chernobyl’s by several orders of magnitude. It is difficult to make a case that it would not (at minimum) be the end of Tokyo as a habitable city. (The implications of this alone are difficult to comprehend. It would mean relocating over 30 million people, and who knows what for the global financial system.) Less bad for the environment but almost as bad for Tokyo would be if the reactor cores melts its way down to the city’s aquifer, which runs under the plant. Again, a very real possibility.

Such fears, should they be realized, would come as ‘surprises’ to the vast majority of the media-reading public, but they really shouldn’t. The mainstream media might be ignoring these issues for now, but there are plenty of knowledgeable people trying to make themselves heard about the dangers. This article, for instance, does a pretty good job of summarizing some of the issues.
