The superconducting magnets in the reactor can work only at supercold temperatures near absolute zero, which will be maintained by liquid helium circulating through cryogenic pumps. Operators control the system via a complex set of hand valves (top) based on local readings of pressure, temperature and flow. The finished cryogenic plant, built by contractor Air Liquide (bottom), will be the world’s largest helium-refrigeration unit.

ITER’s fusion plasma will be encased and contained by a nest of magnets, including six ring-shaped superconducting poloidal magnets (shown here) that will pile on top of one another horizontally to surround the plasma. In addition, 18 toroidal field coils will encircle the machine vertically, and one large central solenoid will sit in the middle, forming the largest superconducting magnet system ever built. Superconductors allow electric current to flow without resistance, enabling electrons to move freely to create intense magnetic fields.

Some potential failures seen by astrophysicst Mr. Jean-Pierre Petit
1. "All the tokamaks in the world including Tore Supra and JET have become ungovernable under the effect of extremely varying causes "
2. "the disruptions …spawn forces that are capable of distorting the parietal structures into wisps of straw"
3. :" lightening produced there will inevitably reach 15 million Amperes (150 million amperes on its successor DEMO). Impacts of such power will perforate the vacuum vessel. The Beryllium layer …will vanish and disperse the materials it is made of--- along with the tritium at the same time--- which is radiotoxic and confined in the chamber"
4: "the hope that one day a tokamak can operate with no disruption is as senseless as imagining the sun with no solar disruptions, a weather report exempt of any wind or snow or cooking oneself a casserole filled with boiling water that produces no flurry"

The Illusion
The US Department of Energy has nearly tripled its cost estimate for ITER, the fusion test reactor in France that’s being constructed by a seven-party international collaboration, to $65 billion.
Paul Dabbar, DOE undersecretary for science, provided the estimate to the Senate Appropriations subcommittee on energy and water development on 11 April 2017. The $65 billion covers construction alone, he said; annual operating costs once experimental operations begin in 2025 aren’t included.
