FUsion Energy Lexicon: Description back to ToC

FUsion Energy Lexicon (FUEL) is an OWL ontology for the interoperable description of fusion energy data, devices, plasmas, physical processes and other fusion energy concepts. FUEL provides a formal semantic framework for organizing fusion knowledge and it is intended to support consistent data annotation, integration, exchange, and reuse across fusion experiments, models, and computational workflows.

IRI: http://w3id.org/fuel/blanket

The lining of the inner wall of the tokamak vessel that will be in direct contact with the hot plasma. The blanket is usually made of modules (from stainless steel, or copper), on which can be mounted replaceable first-wall panels (made from beryllium, tungsten, molybdenum, or carbon in case of older tokamaks), able to withstand high temperatures. The blanket protects the chamber wall and the magnetic coils from high-energy neutrons. These slowdown in the blanket material and transform their energy into thermal energy.

A Langmuir probe is a device used to determine the electron temperature, electron density, and electric potential of a plasma.

The measured currents and potentials in this system allow the determination of the physical properties of the plasma.

magnetic fieldc back to ToC or Class ToC

IRI: http://w3id.org/fuel/magnetic_field

A vector field showing how magnetic forces are distributed in space. A magnetic field describes how the magnetic force at a given point in space will act on a ferromagnetic object or charged particle. In a magnetic field, the Lorentz force on a charged particle is perpendicular to both the direction of the magnetic field and its velocity. Magnetic fields surround magnetized objects, are formed around conductors through which electric current flows, or at a point with a varying electric field. It is described by the quantities B and H. B is the magnetic flux density and is given in units of tesla. A common refrigerator magnet is usually 0.001 tesla. The quantity H describes the magnetic field strength and is expressed in amperes per meter. Rotating magnetic fields are used by electrical generators in power plants. In thermonuclear fusion research, a strong magnetic field is used to confine hot plasma in tokamaks and stellarators.

Instabilities driven by the energy of the magnetic field and by the momentum of charged particles in the plasma. Small displacements of plasma density from the equilibrium position can reinforce that displacement until a further compensating force counteracts that reinforcement or the plasma equilibrium configuration is disrupted. Various modes of such displacement in the toroidal and poloidal planes can be stabilised so that the bulk plasma remains in position.

nuclear reactorc back to ToC or Class ToC

IRI: http://w3id.org/fuel/nuclear_reactor

A device inside which a controlled chain fission reaction takes place. The reactor usually has the form of a metal pressure vessel, in the middle of which the nuclear fuel is arranged in a so-called core. A coolant, whether gas or liquid, circulates through the core to dissipate the heat generated by the fission reaction. The power of the reactor is controlled by control rods that are inserted or withdrawn from the core as necessary. If the reactor uses thermal neutrons for fission, it also includes a moderator, either in the form of a liquid or a solid, which slows down the neutrons. Heat, generated by a reactor, is most commonly used. Either directly for technological purposes (e.g., hydrogen production by steam reforming) or for electricity generation by a steam turbine. The reactor can also be used to produce nuclear fuel (breeder reactor), or the strong neutron fluxes produced by the reaction can be used for research purposes or for the production of radiopharmaceuticals. There are a number of types of nuclear reactors, with the most common types used for electricity generation being water-cooled PWRs and BWRs. In 2023, there were 436 nuclear reactors in operation in the world.

In a star as in a fusion device, plasmas provide the environment in which light elements can fuse and yield energy. Some 99% of the known universe is in the plasma state. Examples of plasmas include the sun, fluorescent light bulbs, and other gas-discharge tubes.

IRI: http://w3id.org/fuel/spherical_tokamak

Tokamak with a low aspect ratio and a round plasma in a shape resembling a cored apple. While a conventional tokamak has a more donut-like shape with a central hole, a spherical tokamak minimizes this hole to achieve a higher compactness. A single common conductor runs through the centre of the tokamak, to which toroidal magnets in the shape of semicircles are connected. Due to its more compact shape, the spherical tokamak achieves the same plasma parameters as a conventional tokamak with a lower magnetic field. This allows it to be smaller and cheaper. Typical spherical tokamaks are the Small Tight Aspect Ratio Tokamak (START) or the Mega Ampere Spherical Tokamak (MAST).

IRI: http://w3id.org/fuel/stellarator

A device for thermonuclear fusion research that uses a combination of differently shaped coils which together create a desired helical magnetic field to confine the hot plasma. To hold the particles in the donut-shaped magnetic container, they must circulate in spirals, once on the inside and once on the outside of the torus. The stellarator creates a suitable magnetic field by combining helical, toroidal and poloidal coils. There are many variations that use different combinations and shapes of coils (classical, heliac, heliotron, torsatron, and helias). In the most modern modular stellarators, an assembly of specially twisted coils creates the magnetic field.

thermocouplec back to ToC or Class ToC

IRI: http://w3id.org/fuel/thermocouple

A thermocouple is a temperature-measuring device consisting of two wires of different metals joined at each end. One junction is placed where the temperature is to be measured, and the other is kept at a constant lower temperature. A measuring instrument is connected in the circuit. The temperature difference causes the development of an electromotive force (known as the Seebeck effect) that is approximately proportional to the difference between the temperatures of the two junctions. Temperature can be read from standard tables, or the measuring instrument can be calibrated to read temperature directly.

tokamakc back to ToC or Class ToC

IRI: http://w3id.org/fuel/tokamak

A device for magnetic confinement of plasma by a combination of a toroidal magnetic field and a current flowing through the plasma in which conditions for thermonuclear fusion ignition can be achieved. The word “tokamak” is of Russian origin and is an acronym for “TOroidalnaya KAmera i MAgnitnye Katushki” — toroidal chamber and magnetic coils. The magnetic field necessary to keep the hot plasma inside the toroidal chamber is generated as a combination of the field of the toroidal coils and the magnetic field generated by the current flowing through the plasma. Since the current in the plasma is induced on the transformer principle, the tokamak is a pulse device.
