Two Fusion Researchers Explain The Tokamak Reactor That I Want To Be Hurled Into. ITER will be the world's largest tokamak, with a plasma radius (R) of 6.2 m and a plasma volume of 840 m³. No tokamak reactor (or fusion reactor, period) has yet reached net productive energy. TFTR set a number of world records, including a plasma temperature of 510 million degrees centigrade -- the highest ever produced in a laboratory, and well beyond the 100 million degrees required for commercial fusion.

Established in 2009, Tokamak Energy is striving to harness the significant potential of fusion power to deliver an abundant, safe and cost-effective source of clean energy to the world. Thanks to the expertise of its world-class team of scientists and engineers, the company’s compact, spherical tokamak has already been proven to be a viable route to fusion. The tokamak is an experimental machine designed to harness the energy of fusion. Fusion research time to set a new path: the inherent limitations of the tokamak design for fusion power will prevent it from becoming commercially viable, but the lessons from this effort can inform future research Apart from any fair dealing for the purpose of private study or research, no and Terms of Use.
