Understanding nuclear fusion milestone and what does it mean?

Scientists in the US have got major breakthroughs in their pursuit of a technique that could produce a practically endless supply of energy. A plus point of Nuclear fusion is that it does not depend on substances such as fossil fuels and also does not produce any harmful gasses. As a result, Nuclear fusion can prove to be extremely helpful in climate change.

What is nuclear fusion?

Nuclear fusion refers to the process which provides the sun with its energy. In a nutshell, it entails the collision of light atoms to create heavier ones, which releases enormous amounts of energy in the process.

In nuclear fusion, two atoms are heated up and compelled to fuse to form a heavier atom. It is the opposite of nuclear fission, which is the splitting apart of heavy atoms. Electricity is currently produced via nuclear fission in nuclear power plants.


At the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California, a weak laser beam is divided and its energy is increased to produce 192 laser beams. These are used to generate X-rays by heating the hohlraum, a small gold container, to a temperature greater than 3 million degrees Celsius.



A millimeter-sized capsule within the hohlraum is heated by these X-rays. Further, the capsule contains two forms of hydrogen: deuterium and tritium. Due to the heat, the surface of the capsule blows up outwards. As a result, the contents of the capsule implode. The end outcome is that fusion takes place in the fuel's hottest region, producing helium nuclei.

The difference in mass between one helium nucleus and the combination of one deuterium and one tritium nucleus is released as a burst of energy. The helium nuclei created in this process can transfer their kinetic energy to the remaining fuel under the correct circumstances, heating it and igniting further fusion.
