The HL-2M tokamak reactor in Chengdu, Southwest China's Sichuan province completed its first discharge on Dec 4, signifying China's independent mastery of the design and construction of large, advanced tokamak devices and their operating technology.
This has laid a solid foundation for the independent design and construction of China's nuclear fusion reactor.

The HL-2M tokamak reactor is currently the largest advanced tokamak device in China with the highest parameters. It is the country's next-generation advanced magnetic confinement nuclear fusion experimental research device.
The device adopts an advanced structure and control method, the plasma volume is more than twice that of existing domestic devices, the plasma current capacity is increased to more than 2.5 megaamps, and the plasma ion temperature can reach 150 million degrees. This means it can achieve high density, high specific pressure, and high bootstrap current operation.
It is an important supporting device in terms of realizing the leap-forward development of China's nuclear fusion energy development, and it is also an indispensable platform on which China can digest and absorb ITER technology.
The project was approved by the China Atomic Energy Authority in 2009, and was independently designed and constructed by the Southwestern Institute of Physics of China National Nuclear Corporation (CNNC).
Prior to this, CNNC has successively developed various types of magnetic confinement fusion research devices, and built three major national scientific research facilities - HL-1, HL-1M and HL-2A - and achieved a series of major scientific research results.
