If the fuel rods are no longer being cooled — as has happened at all three reactors at the Fukushima Daiichi power plant operating at the time of the earthquake — then the zirconium cladding will swell and crack, releasing the uranium fuel pellets and fission byproducts, such as radioactive cesium and iodine, among others.

At Hanford there were nine production reactors making plutonium and uranium fuel using at least six different radiochemical processes whose chemistry, and thus constituents, were very different.
