Nuclear fusion in the ITER reactor

Heavy hydrogen atoms

Deuterium

Plasma

150 million°C

Neutron

Energy

Tritium

Fused atoms

Helium

1. Nuclear fusion occurs when two atoms combine to form a new atom and a neutron

 

2. The atoms are fired into a plasma where extreme temperatures overcome their repulsion and forces them together

 

3. The fusion releases about four times the energy produced when an atom is split in conventional nuclear fission
