The fuel, like I said, is ceramic inside zirconium fuel rods, and in the event of an accident in one of these type of reactors, Fukushima and Three Mile Island -- looking back at Three Mile Island, we didn't really see this for a while — but these zirconium claddings on these fuel rods, what happens is, when they see high pressure water, steam, in an oxidizing environment, they'll actually produce hydrogen, and that hydrogen has this explosive capability to release fission products.
Gorivo, kao što sam rekao, je keramika unutar cijevi obloženim cirkonijem, i u slučaju nesreće u ovakvom reaktoru, Fukushima i Three Mile Island -- retrospektivno na Three Mile Island, nismo to vidjeli neko vrijeme -- no oblog cirkonija na cijevima goriva, kada vidi vodu pod visokim pritiskom, paru, u oksidirajućem okolišu, proizvodi vodik, a taj vodik ima eksplozivnu sposobnost da ispusti produkte fisije.
