   Answer: (2) Uranium

   సమాధానం: (2) యురేనియం

   Uranium-235 is the fissile fuel that splits on absorbing a slow neutron and keeps a fission chain reaction going in reactors. Thorium is only fertile, because it must first be converted to U-233. Barium is one of the products of uranium fission, not its fuel.
