There are lots of stories flying about, some quite wild. Here’s what the IAEA Director says.
The situation at the Fukushima power plant is very serious. Damage to the cores of the three units, unit 1, units 2 & 3, have been confirmed. There has been no serious change since yesterday. The cores remain uncovered, one to two meters. We do not know the exact situation inside the reactor vessels. But the pressure inside remains at about atmospheric pressure. This suggests that they remain largely intact.”
