Meltdown?

There's the threat of a meltdown at the reactor in Japan. Some of the fuel rods were exposed and started to overheat. They are pumping seawater in to cool down the fuel rods. Some people have been exposed to radiation  and they have been given iodine pills to help with exposure. Here's hoping they can get this situation under control quickly. The last thing the Japanese need is a nuclear accident on top of everything else.
