The operator of Japan's infamously crippled Fukushima nuclear power plant recently attempted to move some radioactive water from one tank to another. In the process, it spilled four tons of deadly sludge.
To be fair, the four tons of water is just a drop in the bucket compared to the 300 tons that recently leaked from a nearby tank. And the radiation levels in the newly leaked water are relatively low compared to puddles they found forming outside the tanks about six weeks ago. TEPCO's not in the clear yet, though. A tropical storm is on the way, which creates the potential for even more radioactive leaks.
