More than Two Years
After The Initial Meltdowns, Fukushima is Still SNAFU

Situation Normal, All Fukushima'd Up
The first thing to know about the danger from the radioactive mass remaining on site in the three reactors that melted down at Fukushima is that nobody knows how much radioactive material there is, nobody knows how much uranium and plutonium it contains, and nobody knows how to make it safe -- so no one knows how great the continuing danger is.
In order to prevent nuclear material from being diverted to use in weapons, the International Atomic Energy Agency of the U.N. requires each country to report regularly on the volume of nuclear materials in its nuclear power plants. At Fukushima, this is currently impossible with the cores of the three reactors that melted down.
Diversion of this material to weapons use is not a problem at the moment, since the level of radioactivity is high enough to kill anyone who comes close to it, which is why it hasn't been moved. On the other hand, it is necessary to move it in order to measure it, and even if it was movable now, the technology to measure it does not yet exist.
