According to the WeChat public account of China National Nuclear Corporation on the 26th, the new generation of artificial sun “China Gyre-3” made major scientific research progress on the afternoon of the 25th, and for the first time achieved a high-constraint mode operation under a plasma current of 1 million amperes, which once again refreshed the magnetic confinement fusion in mainland China. The operation record of the device has broken through key technical problems such as plasma high-current high-constraint mode operation control, high-power heating system injection coupling, and advanced divertor configuration control. Confinement fusion research has taken an important step towards high-performance fusion plasma operation.
In order to realize fusion energy, it is necessary to improve the comprehensive parameters of plasma to the conditions of fusion ignition. 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, as a cutting-edge disruptive technology oriented to major national needs, has outstanding advantages such as rich resources, environmental friendliness, and inherent security. It is currently recognized as one of the important ways to finally solve human energy problems. , The construction of national defense industry has important strategic significance. Controllable nuclear fusion is an important part of the three-step strategic system of “thermal neutron furnace-fast neutron furnace-nuclear fusion furnace” in China’s nuclear energy development. Key technological variables to promote the construction of a new energy system and ensure national energy security.
On the basis of realizing the high-constraint mode operation of the million-ampere plasma current, the team of the new-generation artificial sun “China Circulation No. 3” will further develop core technologies such as high-power heating and current drive, and advanced plasma operation control to achieve core-level Plasma operation, research on cutting-edge fusion physics, and lay a solid foundation for China to carry out fusion combustion experiments and independently build fusion furnaces.
