I’m wondering about the possibility of  China Syndrome event happening at the reactor in Japan.

Some experts are saying that part of the core may have turned molten, but that

At Fukushima, the drywell has been flooded with seawater, which will cool any molten fuel that escapes from the reactor and reduce the amount of radioactive gas released.

But what if the water is insufficient to cool molten material leaking through? One view is that the worst-case is that the chemicals in the molten mass would react with concrete containment material underneath, sending particles up and out of the facility.

But what if the cooling water is not sufficient to keep things cool? Then we could have a China Syndrome, with molten material melting everything in its path until it hits subsurface water, resulting in eruptions of reactor core material into the atmosphere. Let’s hope not.
