C) A uranium nucleus is energized to an excited state by neutron irradiation, and it then decays by emitting beta rays and gamma rays that heat water and create steam.
D) Uranium is reacted with oxygen in a combustion process that releases large amounts of radioactivity and heat.
E) The radiation given off by a naturally radioactive substance, uranium, is collected and used to make steam.
