The Experimental Advanced Superconducting Tokamak (EAST) reactor in China maintained plasma in a stable state for more than 1,000 seconds (17 minutes), setting a new record in fusion research.The Experimental Advanced Superconducting Tokamak (EAST) maintained plasma for 1,000 seconds, which is more than the previous record of 403 seconds set in 2023. This is an important step towards the development of clean and sustainable energy.
Nuclear Fusion
- Nuclear fusion is a process in which two lighter atomic nuclei combine to form a heavier nucleus and a lot of energy is released.
- This process provides energy to the Sun and other stars.
How Nuclear Fusion Works
- High Temperature and Plasma Formation: Temperatures above 100 million degrees Celsius are required for fusion. At this temperature, atoms split into ions and electrons to form a plasma state.
- Magnetic Confinement: Plasma is controlled using strong magnetic fields so that it does not collide with the walls of the reactor.
- Fusion Reaction: Hydrogen isotopes (deuterium and tritium) fuse together to produce helium and energy.
- Energy Storage and Conversion: In future fusion reactors, this heat will be used to produce steam. This will help in power generation by driving turbines.
Importance of Nuclear Fusion
- Unlimited Energy Source: It is considered the “Holy Grail” of energy production, as it can provide almost unlimited energy.
- Safe for the environment: It has almost no emission of greenhouse gases, which reduces the impact on the environment.
- Will reduce dependence on fossil fuels: Fusion can play an important role in the future to meet the growing global energy demand.
EAST Reactor (China’s “Artificial Sun”)
- Location: It is located at the Institute of Plasma Physics in Hefei, China.
- Purpose: It aims to replicate the nuclear fusion process of the Sun.
- Operational: It has been operational since 2006 and is constantly being tested to increase its capacity and stability.
Other Fusion Projects in China
- HL-2A and J-TEXT: Several other Tokamak reactors are being operated in China.
- HL-2M Tokamak: It is China’s largest and most advanced fusion device. It was successfully commissioned in December 2020.
- Green Development and Sustainable Energy: These projects reflect China’s commitment to green development and sustainable energy.
