There are more than 1,000 spent fuel rods at Fukushima Daiichi plant.  So far attempts to cool the rods down with water is failing.

To show how hard it is to cool down spent fuel rods: It takes 3 to 4 years under normal conditions.

The large amount of spent fuel rods, at the plant,  means a massive melt down could occur if temperatures can not be brought down.  As one U.S. nuclear engineer said, even a fuel rod fire would be like “…Chernobyl on steroids.”

No wonder many countries are telling their people to get out of Japan.
