Nuclear Fusion

Nuclear fusion is a process in which two atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy. This process is the source of energy for the sun and other stars. It is also being studied as a potential source of clean and abundant energy here on Earth.

Process of Nuclear Fusion

In nuclear fusion, two light atomic nuclei, typically isotopes of hydrogen such as deuterium and tritium, are brought together under high temperature and pressure. When these nuclei collide, they overcome the electrostatic repulsion between them and fuse to form a heavier nucleus, releasing a tremendous amount of energy in the process.

Conditions for Nuclear Fusion

Nuclear fusion requires extremely high temperatures (in the range of millions of degrees Celsius) to overcome the repulsive forces between the positively charged nuclei. Additionally, high pressure is necessary to confine the hot plasma where fusion occurs. These conditions are similar to those found in the core of stars.

Applications of Nuclear Fusion

If harnessed successfully, nuclear fusion has the potential to provide a nearly limitless and clean source of energy. It produces no greenhouse gases or long-lived radioactive waste, making it an attractive option for future energy generation.
