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.
Nuclear fusion occurs naturally in the centre of a Star due to the high temperatures and pressure.
Nuclear fusion is possible in laboratories on Earth but it cannot be sustained for long periods of time to produce enough energy to be useful as an energy resource.
Nuclear fusion in laboratories on Earth must be done at much higher temperature than in the centre of Stars because the centre of Stars is a much higher pressure so nuclei collide more often.
