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 force them together

 

3

The fusion releases about four times the energy produced in atom-splitting nuclear fission, per gramme of fuel
