In the best-case scenario, electrical power and cooling would be restored to all of the six units of the plant, said Tom Kauffman, spokesman for the Nuclear Energy Institute, a policy organization of the nuclear energy and technologies industry in Washington.

And just what is that worst-case scenario? "They're venting in order to keep the containment vessel from failing. But if a core melts, it will slump to the bottom of the reactor vessel, probably melt through the reactor vessel onto the containment floor. It's likely to spread as a molten pool—like lava—to the edge of the steel shell and melt through. That would result in a containment failure in a matter of less than a day. It's good that it's got a better containment system than Chernobyl, but it's not as strong as most of the reactors in this country."
