Reactors in which energy release is caused by the controlled fusion of atomic nuclei, namely:

Thermonuclear fusion reactors.

Low-temperature nuclear fusion reactors, e.g. alleged cold fusion reactors.

systems and components for producing energy by nuclear fusion reactions taking place in a thermonuclear plasma, in particular all parts related to the confinement, ignition and sustainment of the plasma.

The general rule of classification in this subclass follows the IPC rules, i.e. the invention information is classified with an EC class.

Reactors composed of nuclear fusion systems combined with nuclear fission systems, whereby neutrons generated by the fusion reactions are used for generating nuclear fission reactions.

Reactors in which nuclear fusion reactions are initiated by heating and compressing a fuel target, typically in the form of a pellet containing the nuclear fuel.

Reactors in which nuclear fusion reactions take place between atomic nuclei of a nuclear fuel in a plasma state, whereby magnetic fields are used to confine the plasma and electromagnetic fields are used to ignite and sustain the plasma.

Reactors in which the plasma containment system comprises a chamber, a magnetic field generator for applying a magnetic field in a direction substantially along a principle axis, and an annular plasma layer that comprises a circulating beam of ions, wherein the internal magnetic field reverses direction.

Closed-loop reactors in which the magnetic confinement is produced with a single coil system. As the helical twisting of field lines is achieved solely with external coils, the latter have to be twisted accordingly.

Closed-loop reactors using magnetic fields to confine the plasma in the shape of a torus with a doughnut cross-section. A toroidal magnetic field is generated by electromagnets encircling the torus. A poloidal field is generated by a poloidal electric current that flows inside the plasma, this current being induced inside the plasma by a second set of electromagnets.
