Unformatted text preview: trapped within the fuel's structure very near the point at which they were generated by fission. The fuel cladding which encases the nuclear fuel is designed to contain the remaining 1 percent. The release of fission products from the fuel rods would require a breakdown of the fuel cladding. If the core is not sufficiently covered with water to provide cooling, it could overheat resulting in a breakdown of the fuel cladding and the release of fission products in a short period of time. Additional overheating could cause the release of some of the 99 percent of the fission products normally trapped in the fuel structure. Still more overheating could cause the fuel to actually melt. This is often referred to as a "meltdown"....
