help me out here, what, where are they?
Fukushima, Japan. The fuel has melted through the containment structures and is thought to be residing in water filled basements or have gone further down through the basements and are feared heading to the water table but nobody knows. They are generating large amounts of contaminants around the clock. And there are signs that criticality is resuming now and then (presence of short half life isotopes). The Japanese claim that they brought one molten lump of corium to ‘cold shutdown’ status because a measurement they took somewhere under the reactor read less than 100 degrees. This hasn’t stopped the reactor from releasing contaminants. Japan promises to bring all three lumps of corium to ‘cold shutdown’ status by the end of the year. http://ex-skf.blogspot.com/search/label/cold%20shutdown
