Key Stage 4

Meaning

Nuclear fusion is a process in which two small atomic nuclei join together to become a larger nucleus.

About Nuclear Fusion

For a fusion reaction to occur the two nuclei must have enough kinetic energy to overcome the electrostatic force of repulsion between the positively charged nuclei.
To provide enough kinetic energy to the nuclei the substance must be heated to a temperature of several million degrees Celsius.
