I've been a proponent of nuclear power. I'm still a proponent of nuclear power. But because I endorsed the view that there was nothing to worry about at Fukushima and that nuclear power is the safest way to generate electricity (which it actually still is) I feel duty bound to point out this article from Al Jazeera (which nowadays seems to be a fairly reliable source) that says that the situation at Fukushima is pretty frickin' bad, much worse than official sources would have one believe.
Because reliable information from Fukushima is so hard to come by it is probably impossible to say if this article has overblown the actual danger. But the article seems plausible to me. I still believe it is possible to design and build safe reactors. But at this point I don't see how any reasonable person could fail to concede that Fukushima manifestly wasn't.
