The Japanese government released details of their plan to tear down the Fukushima Daiichi nuclear plant.

From 2012 to 2015 they hope to remove the hundreds of spent fuel rods stored in the facility’s spent fuel pools.

Then from 2015 to 2021 they will work to repair and fill up the highly radioactive reactor containment vessels with the melted fuel rods inside.  That plan involves using water to fill the containment vessels on four reactors.

Then by 2022 they hope they can figure out a way to safely remove the melted fuel rods from the containment vessels.  The ultimate goal is to tear down the reactor buildings.
