Administration.release energy, atoms of uranium are bombarded by a small particle called a neutron. This pro-
cess splits the atoms of uranium and releases more neutrons and energy in the form of heat and
radiation. The additional neutrons go on to bombard other uranium atoms, and the process
keeps repeating itself, leading to a chain reaction. This process is shown in Figure 13.19. The
fuel most widely used by nuclear power plants is Uranium 235 or simply U-235. The U-235
