english: 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.
non_english: Kao što sam rekao, gorivo je keramika unutar šipki cirkonijuma, i u slučaju nesreće  sa jednim od ovih reaktora, Fukušima i ostrvo Tri Milje - gledajući na ostrvo Tri Milje,  ovo zaista dugo nismo videli - ali ove obloge od cirkonijuma  na šipkama goriva, kada vide vodu  pod visokim pritiskom, paru, u okruženju koje oksidira, zapravo će proizvesti vodonik, i taj vodonik ima  ovo eksplozivno svojstvo da ispušta proizvode fisije.
