Joint European Torus (JET)

Why is it in the news?

  • Researchers achieved increased power output from nuclear fusion utilizing the Joint European Torus (JET) tokamak in the United Kingdom.
  • As the largest operational tokamak in the world, JET has played a crucial role in fusion research.
  • It was the first device to achieve controlled fusion power with a combination of deuterium and tritium.

 

About Nuclear Fusion Process

路聽聽聽聽聽聽 Nuclear fusion is the process by which two light atomic nuclei combine to form a single, heavier nucleus.

路聽聽聽聽聽聽 This process releases enormous amounts of energy, similar to the energy produced by the sun and stars.

路聽聽聽聽聽聽 The fusion of hydrogen isotopes, deuterium and tritium, is of particular interest due to its potential for practical energy generation.

 

Advantages of Nuclear Fusion

路聽聽聽聽聽聽 Unlike fossil fuels, nuclear fusion reactions produce only small amounts of helium as by-products, with no carbon emissions.

路聽聽聽聽聽聽 Deuterium, one of the fuels used in fusion reactions, can be extracted from water, making it widely available.

路聽聽聽聽聽聽 Fusion reactions have the potential to provide a consistent and reliable source of energy, as they can continue to produce energy for longer periods compared to traditional energy sources.

Challenges

路聽聽聽聽聽聽 Fusion reactions require extremely high temperatures, typically exceeding 100 million degrees Celsius, to overcome the electrostatic repulsion between atomic nuclei.

路聽聽聽聽聽聽 During fusion reactions, high-energy neutrons are released, which can penetrate materials and cause structural damage to the reactor components.

 

India’s Initiatives聽

路聽聽聽聽聽聽 In 2005, India joined the International Thermonuclear Experimental Reactor (ITER) project, a global collaboration aimed at building the world’s largest tokamak reactor.

路聽聽聽聽聽聽 The Institute of Plasma Research (IPR), an autonomous institute under the Department of Atomic Energy (DAE), leads India’s fusion program. The institute conducts research and development activities related to fusion energy, plasma physics, and related technologies.
