Fusion Power is generated by harnessing the energy released by replicating the fusion processes that happen within stars e.g. The Sun. The Sun uses hydrogen as a fuel and the core temperature of our Sun is estimated to be 15million°C, however the fusion rate for hydrogen is very slow, in order to generate power by the fusion within a machine on earth, we need to use a different fuel based on heavy hydrogen called Deuterium and Tritium, which requires plasma temperature in the region of 100 million°C. This is achieved in a fusion reactor or machine commonly known as a tokamak (Russian word токамак).
