Type One Energy, which has developed an alternative to the tokamak magnetic confinement systems typically used in nuclear fusion, submitted an initial licensing application for a fusion facility Lithium, beryllium, and boron, despite their low atomic number, are rare because, although they are produced by nuclear fusion, they are destroyed by other reactions in the stars. Learn how nuclear fusion works in stars like the Sun and how it could be harnessed for energy production on Earth. But nuclear fusion's no walk in the park. The Sun is a main-sequence star, and, as such, generates its energy by nuclear fusion of hydrogen nuclei into helium. Learn how proton-proton fusion produces energy and light from the Sun's core. Four million tons of mass converted to pure energy every second. Harnessing fusion's power is the goal of ITER—designed as the key experimental step between today's fusion research machines and tomorrow's fusion power plants. The United Kingdom has achieved a major milestone in nuclear fusion research, demonstrating a controlled fusion experiment that released a record amount of fusion energy. [4][5] Their natural occurrence is the result of cosmic ray spallation of carbon, nitrogen and oxygen in a type of nuclear fission reaction.
