HT-7
Encyclopedia
HT-7, or Hefei Tokamak-7, is an experimental superconducting tokamak
nuclear fusion
reactor built in Hefei
, China
, to investigate the process of developing fusion power
. The HT-7 was developed with the assistance of Russia, and was based on the earlier T-7 tokamak reactor. The reactor was built by the Hefei-based Institute of Plasma Physics under the direction of the Chinese Academy of Sciences
.
The HT-7 was finished in May 1994, with final tests accomplished by December of the same year allowing experiments to proceed.
The HT-7 will be superseded by the Experimental Advanced Superconducting Tokamak being built in Hefei by the Institute of Plasma Physics as an experimental reactor before ITER
is completed.
Tokamak
A tokamak is a device using a magnetic field to confine a plasma in the shape of a torus . Achieving a stable plasma equilibrium requires magnetic field lines that move around the torus in a helical shape...
nuclear fusion
Nuclear fusion
Nuclear fusion is the process by which two or more atomic nuclei join together, or "fuse", to form a single heavier nucleus. This is usually accompanied by the release or absorption of large quantities of energy...

Fusion power
Fusion power is the power generated by nuclear fusion processes. In fusion reactions two light atomic nuclei fuse together to form a heavier nucleus . In doing so they release a comparatively large amount of energy arising from the binding energy due to the strong nuclear force which is manifested...
