China masters controllable nuclear fusion high-constraint advanced control technology

The new-generation artificial sun "China Circulation No. 3" has made significant scientific research progress, and for the first time realized the high-constraint mode operation under the plasma current of 1 million amperes, which once again refreshed the operation record of my countrys magnetic confinement fusion device and broke through the plasma high-current high-constraint mode operation Key technical problems such as control, high-power heating system injection coupling, and advanced divertor configuration control mark an important step in my countrys magnetic confinement nuclear fusion research towards high-performance fusion plasma operation.

In order to realize fusion energy, it is necessary to increase the comprehensive parameters of the plasma to the fusion ignition conditions. The high confinement mode (H mode) in magnetic confinement nuclear fusion is a typical advanced operation mode, which is selected as the standard operation mode of the International Thermonuclear Experimental Reactor (ITER) under construction, which can effectively improve the overall confinement performance of the plasma , to improve the economy of the future fusion reactor, compared with the normal operation mode, its plasma comprehensive parameters can be increased several times.

Controllable nuclear fusion has outstanding advantages such as abundant resources, environmental friendliness, and inherent safety. It is one of the important ways to finally solve human energy problems that are currently recognized. The new-generation artificial sun "China Circulation No. 3" team will further develop core technologies such as high-power heating and current drive, advanced plasma operation control, realize core-level plasma operation, study cutting-edge fusion physics, and carry out fusion combustion experiments for my country. The independent construction of fusion reactors has laid a solid foundation.
