In 1997, JET set the record for the closest approach to scientific breakeven. It attained Q = 0.67, producing 16 MW of fusion energy while injecting 24 MW of thermal power to heat the fuel, [26] a record that endured until 2021. [27] [28] This was also the record for greatest fusion power produced. [29] [30] In 1998, JET's engineers developed a ...
JT-60 (short for Japan Torus-60) is a large research tokamak, the flagship of the Japanese National Institute for Quantum Science and Technology's fusion energy directorate. As of 2023 the device is known as JT-60SA and is the largest operational superconducting tokamak in the world, [ 1 ] built and operated jointly by the European Union and ...
The Culham Centre for Fusion Energy (CCFE) is the UK's national laboratory for fusion research.It is located at the Culham Science Centre, near Culham, Oxfordshire, and is the site of the Mega Ampere Spherical Tokamak (MAST) and the now closed Joint European Torus (JET) and Small Tight Aspect Ratio Tokamak (START).
The record for Q ext (the theoretical Q value of D-T fusion as extrapolated from D-D results) in a tokamak is held by JT-60, with Q ext = 1.25, slightly besting JET's earlier Q ext = 1.14. In December 2022, the National Ignition Facility, an inertial confinement facility, reached Q = 1.54 with a 3.15 MJ output from a 2.05 MJ laser heating ...
Scientists in the UK announce a new nuclear fusion energy record, bringing the futuristic energy source a step closer to reality
The project is given the name Tokamak Fusion Test Reactor (TFTR). The Kurchatov Institute builds the TO-2, the first tokamak with a divertor, using a toroidal configuration which would soon be superseded by poloidal divertors. [27] 1977. The 20 beam Shiva laser at LLNL is completed, capable of delivering 10.2 kilojoules of infrared energy on ...
The current record of fusion power generated by MCF devices is held by JET. In 1997, JET set the record of 16 megawatts of transient fusion power with a gain factor of Q = 0.62 and 4 megawatts steady state fusion power with Q = 0.18 for 4 seconds. [3] In 2021, JET sustained Q = 0.33 for 5 seconds and produced 59 megajoules of energy, beating ...
Toroidal machines can be axially symmetric, like the tokamak and the reversed field pinch (RFP), or asymmetric, like the stellarator.The additional degree of freedom gained by giving up toroidal symmetry might ultimately be usable to produce better confinement, but the cost is complexity in the engineering, the theory, and the experimental diagnostics.
