- China has successfully powered up its “artificial sun” nuclear fusion reactor for the first time, showing great advances achieved by the country in its nuclear power research capabilities.
- It uses a powerful magnetic field to fuse hot plasma and can reach temperatures of over 150 million degrees Celsius.
- It is located in Sichuan province and often called as ‘artificial sun’ because of the enormous amount of energy it releases.
Nuclear Fusion
Nuclear fusion, process by which nuclear reactions between light elements form heavier elements (up to iron). In cases where the interacting nuclei belong to elements with low atomic numbers (e.g., hydrogen [atomic number 1] or its isotopes deuterium and tritium), substantial amount of energy is released. The vast energy potential of nuclear fusion was first exploited in thermonuclear weapons, or hydrogen bombs, which were developed in the decade immediately following World War II.
