Fukushima Crisis Worsens as U.S. Warns of a Large Radiation Release
This article has a broad overview, but here is this bit...
Excerpt:
'Doomsday' scenarios
But the resulting radiation could be so high, "it would be almost impossible to get anyone in there," to continue supplying water to the damaged reactors, he said. That could put the cores in a meltdown scenario that could lead to an explosion within the core or a leak of puddle fuel from the bottom of the reactor -- "doomsday" scenarios that create the ultimate test of a reactor's designed defenses, he said.
"There is a possibility if the fuel is in the right configuration, has been out of the reactor long enough, and is sufficiently air cooled that a fuel fire would not start," said one U.S. expert. "If there were a fuel fire, the radiation levels off site would go off the charts -- which they have not," he said.
