Does India also want to produce artificial sun after China and Korea?


China’s success in developing a nuclear reactor that mimics nuclear fusion is in the spotlight worldwide. Not only China, South Korea also has a technology called artificial sun This. Other countries could follow suit, India for example?

Like most technologies, nuclear fusion is an invention of a double-edged sword. On the one hand, nuclear fusion fears unwanted accidents.

On the other hand, this technology offers several advantages when used in a friendly manner. It only takes half a kilogram of fusion fuel to produce the same amount of energy as four million kilograms of fossil fuel.

Nuclear fusion does not leave behind any highly radioactive waste, such as is produced by conventional nuclear power plants, and artificial sun viewed as the future of clean energy.

Journey to nuclear fusion

The development of fusion energy is not as simple as theory. Researchers’ initial hopes in the 1950s were dashed by the many associated technical problems of controlling the behavior of plasma complexes containing atomic nuclei in order to coalesce and maintain temperatures above 100 million degrees Celsius.

For years, scientists have worked hard to do this with special reactors called tokamaks, which are donut-shaped chambers with giant rings of magnets that hold overheated plasma and rotating charged particles so they fuse together at extremely high temperatures.

The bigger the tokamak, the better the insulation to keep the fusion particles in place longer, and more energy will be produced.

But even with the latest technology, it is impossible to maintain a high temperature long enough to trigger a fusion reaction. Because of this, the achievement of the Experimental Advanced Supraconductor Tokamak (EAST), the Chinese-made sun that managed to reach a temperature of 160 million degrees Celsius for 20 seconds, is a breakthrough.

The largest fusion reactor

To unlock the potential of fusion energy around the world, the world will rely heavily on the construction of the International Thermonuclear Experimental Reactor (ITER) in southern France. The technology is expected to be the largest fusion reactor in the world when it is commissioned in 2035.

Many critics argue that the reactor is just a technology demonstration. After all, after the International Space Station (ISS), ITER is the largest human project with international cooperation. These include the United States, Russia, South Korea, Japan, China, India, and the European Union.

India could make its own sun

Quoted from Deccan Herald, India can be a dark horse in the development of fusion reactor technology because it plays an important role in ITER. Scientists from the Institute for Plasma Research in Ahmedabad manage the industrial production of critical ITER components such as wall shields, cooling water systems and cryogenics. In fact, the superstructure for the main reactor equipment, where a vacuum is maintained to cool the plasma, was made by the Indian company Larsen & Toubro.

Since building its first tokamak called Aditya in the 1980s, India has made remarkable strides in fusion research, operating a state-of-the-art steady state superconducting tokamak (SST) that overcomes the “on-off” nature of conventional tokamaks in plasma heating.

Few countries have developed this next generation SST. The EAST made in China, for example, is a tokamak designed for stationary use. It should be noted that the Chinese engineers who built it artificial sun all of which are “nourished” by the ITER program.

With this capital city, it is not out of the question that India will be encouraged to make its own sun. They should use their participation in ITER to pave the next step in the construction of a fusion reactor on Indian soil in the coming decades.
