Fusion reactor , also called  fusion power plant  or  thermonuclear reactor , a device to produce electrical power from the energy released in a   Nuclear Fusion  reaction. Fusion power is a theoretical form of power generation in which energy will be generated by using nuclear fusion reactions to produce heat for electricity generation. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, and at the same time, they release energy. This is the same process that powers star like our Sun. Devices designed to harness this energy are known as fusion reactors. Fusion processes require fuel and a highly confined environment with a high temperature and pressure, to create a plasma in which fusion can occur. In stars, the most common fuel is hydrogen, and gravity creates the high temperature and confinement needed for fusion. Fusion ...

Fusion is the process by which the sun and other stars generate light and heat. It is a nuclear process, where energy is produced by smashing together light atoms. It is the opposite reaction to fission, where heavy isotopes are split apart. It’s most easily achieved on Earth by combining two isotopes of hydrogen: deuterium and tritium. Hydrogen is the lightest of all the elements, being made up of a single proton and an electron. Deuterium often called “heavy water”, has an extra neutron in its nucleus. Tritium has two extra neutrons, and is therefore three times as heavy as hydrogen. In a fusion cycle, tritium and deuterium are combined and result in the formation of helium, the next heaviest element in the Periodic Table, and the release of a free neutron. Deuterium is found one part per 6,500 in ordinary seawater and is therefore is globally available, eliminating the problem of unequal geographical distribution of fuel resources. This means that there will be fuel for fusion...
