Fission and Fusion

• Nuclear fission is a large mass splits into two or more smaller nuclei and masses. Energy is released
• Nuclear fission takes place in nuclear power plants
• When a chain reaction occurs neutrons are released and atoms split and go on to produce further chain reactions
• If not kept under control a chain reaction could lead to a nuclear explosion
• Nuclear fusion is where two or more smaller masses combine to form a larger mass nucleus. Energy is released
• Nuclear fusion takes place in the sun and other stars
