Nuclear fusion

• What is nuclear fusion?

  The joining of two light nuclei to produce a heavier nuclei and release energy
• Name two isotopes of hydrogen which are commonly used in nuclear fusion

  Deuterium and Tritium
• Which releases more energy, nuclear fission or nuclear fusion?

  Nuclear fusion
• Explain the difficulty of generating energy through nuclear fusion

  Fusion requires very high temperatures which in itself requires large quantities of energy and also requires casing which can withstand them.
• Explain why nuclear fusion is currently not a viable way to produce energy on earth.

  With current equipment/techniques, the energy required is greater than the energy produced, resulting in a net energy loss.
