Fission and Fusion of Atomic Nuclei

Nuclear Fission Neutron Fission - The splitting of the nucleus into fragments (division)

Chain Reaction

Nuclear Fusion Fusion - combining atomic nuclei to produce a nucleus of greater mass Fusion reactions release more energy than fission reactions Sun is powered by fusion

euterium ritium

Nuclear Binding Energy The energy required to break a nucleus into its individual protons and neutrons

Mass Defect When breaking apart a nucleus, there is a change in mass called the mass defect. The change in mass was converted to energy. We know this as E=mc2

Nuclear Reactors The purpose of nuclear reactors is to keep the chain reaction going without letting it get out of control

Diablo Canyon

San Onofre

Fukushima, Japan

Nuclear Bombs Atomic Bomb Hydrogen Bomb Uses fission Uses enriched uranium-235 or plutonium Nagasaki and Hiroshima Uses fusion 1000 time more powerful than atomic bomb Uses deuterium 2H and tritium 3H
