Nuclear contaminated water leaking from storage tanks at Fukushima site
Over the last couple of days, Japanese electrical company TEPCO has announced that they found leaks in three of the seven underground tanks used to store contaminated water at the site of the Fukushima Daiichi power plant
. They've also admitted that the tanks aren't reliable
. And here's where we get to the fun part: Despite that fact, there aren't many other options. The water is stuff that's been used to cool down fuel rods that melted during the April 2011 disaster. You have to put water on the fuel rods, or they could overheat again. But once you're done with that water, it's not particularly safe, either, so you have to contain it somehow. And until other options can be built these tanks are the only place to put it.
The third, most recent, leak was found when TEPCO tried to move water from the known-to-be-leaky tanks to another they thought was in good shape. This is just a mess.
