It seems too impossible to believe, but according to reports from CNN, Reuters and the AP tonight, the last workers at the Fukashima-Daiichi reactors have been withdrawn from the scene, halting efforts to continue cooling partially melted fuel rods with ocean water. Just a day earlier 750 more workers had been removed. Exhaustion, radiation exposure, hopelessness–we don’t yet know the reason for this latest move. Earlier in the day new fires, explosions and clouds of smoke or steam were spotted. Maybe the evacuation means that the worst of the danger is over (how else could they leave?) — but that doesn’t seem likely.
