What does plasma do in an ITER?

Fusion plasmas provide the environment in which light elements can fuse and yield energy. In a tokamak device, powerful magnetic fields are used to confine and control the plasma.

What is ITER tokamak?

The ITER Tokamak The tokamak is an experimental machine designed to harness the energy of fusion. ITER will be the world’s largest tokamak, with a plasma radius (R) of 6.2 m and a plasma volume of 840 m³.

Who is funding ITER?

ITER is funded and run by seven member parties: China, the European Union, India, Japan, Russia, South Korea and the United States.

What is the cost of ITER?

ITER is now expected to cost at least $21 billion and won’t turn on until 2020 at the earliest. And a recent review slammed ITER’s management.

How do magnets contain plasma?

By setting up magnetic field lines toroidally around the interior of the tokamak , the ions and electrons in the plasma are forced to travel tightly around these field lines, preventing them from escaping the vessel. Extra fields help shape the plasma and hold it stable within the tokamak interior.

How do we contain plasma?

Scientists are able to contain or “confine” the plasma away from the walls by exploiting its properties. Plasmas consist of charged particles—positive nuclei and negative electrons—that can be shaped and confined by magnetic forces.

What is the goal of ITER?

One of the primary goals of ITER operation is to demonstrate control of the plasma and fusion reactions with negligible consequences to the environment.

Is ITER operational?

ITER will begin operations with low-power hydrogen reactions in 2025. But from 2035, it will run on a 50:50 mix of deuterium and tritium.

What will ITER do?

ITER is designed to produce a ten times return on invested energy: 500 MW of fusion power from 50 MW of input heating power (Q=10). It will be the first of all fusion experiments in history to produce net energy.

Is ITER still under construction?

Construction. The ITER Project is currently under construction on a 180-hectare site in southern France. Thirty-nine buildings and technical areas house the ITER Tokamak and its plant systems.

How much funding does ITER get?

London — The European Council has agreed Eur5. 61 billion ($6.80 billion) of new funding for the International Thermonuclear Experimental Reactor, or ITER, project for the seven years to 2027, it said Feb. 22.

Is ITER a failure?

This, together with our incomplete knowledge of what to expect in the thermonuclear regime, makes ITER a risky project, whose failure could cause irreparable harm to the credibility of nuclear fusion.
