Fukushima – a year on

It’s almost a year since the Japanese earthquake that produced a tsunami and consequent disaster at the Fukushima Daiichi Nuclear Power plant on March 11th 2011.

Here’s a video, produced by Nature magazine, showing the continuing efforts to clean up.

I’ve been teaching Nuclear Physics this term and while I was talking about chain reactions, neutron capture, control rods and the like, the other day I suddenly realised that the class of twenty-somethings in front of me had all been born after Chernobyl and were probably unaware of just how scary it was at the time. The current generation of students, and those following it, will be among those who are going to have to grapple with a very serious problem as oil and gas supplies dwindle over the next decades. People can make their own mind up about what’s the best way to tackle this crisis, but my view is that at least in the short term we’re stuck with nuclear fission reactors for at least some of our energy needs – with improved energy efficiency and appropriate use of renewable sources helping – until fusion power comes to the rescue.
