Disadvantages: Nuclear waste, reactor failure is potentially dangerous to millions. Nuclear Fission and Fusion (p26) Nuclear fission is when a neutron collides with a nucleus, causing it to split. When the nucleus is split, further neutrons break off and cause further fission reactions. Heat energy is produced by the bonds of the nucleus breaking. Boron Control Rods absorb neutrons. Graphite Moderator slows down neutrons. Uranium Rods are the fuel for the reactions.
