Construction of the International Thermonuclear Experimental Reactor, or ITER, progresses in Provence, France, as the multinational consortium aims to demonstrate the scientific and technological feasibility of fusion energy. The project, a collaboration between the European Union, U.S., China, India, Japan, Russia, and South Korea, is designed to be the world's largest tokamak. Its primary scientific goal is to produce 500 MW of fusion power from 50 MW of heating power, achieving a plasma energy gain, or Q_plasma, of 10. This would represent a significant step beyond the breakeven records set by previous experiments and is intended to validate the physics required for a commercial fusion power plant.

The scale of the ITER device is substantial, designed to contain a plasma volume ten times larger than any preceding fusion machine. To achieve its target performance, the reactor must heat a deuterium-tritium fuel mixture to temperatures exceeding 150 million degrees Celsius, approximately ten times hotter than the core of the sun. This superheated, ionized gas, or plasma, will be confined by a powerful magnetic field generated by massive superconducting magnets. The successful confinement and heating of a stable plasma at this scale for sustained periods are critical objectives for the project's operational phase. Source: Bloomberg

The project's management, under the late Director-General Bernard Bigot, implemented a revised schedule to address earlier delays and cost overruns that have characterized the complex international undertaking. As of the 2019 reporting, the timeline projected first plasma for 2025, with the introduction of deuterium-tritium fuel for high-power operations slated for 2035. The total project cost is estimated to be at least $22 billion. The European Union bears the largest share of the cost at 45%, with the other six partners contributing approximately 9% each, primarily through in-kind component manufacturing and delivery.

Despite its scientific ambitions, ITER is not designed to generate electricity. Its purpose is purely experimental: to prove that a burning plasma can be controlled and sustained, producing significantly more thermal energy than is required to heat it. The data and operational experience gained from ITER are intended to inform the design of a subsequent demonstration power plant, often referred to as DEMO, which would be the first fusion facility to connect to the electrical grid. The success of the tokamak design at this scale is a pivotal question for the future of magnetic confinement fusion. Source: Bloomberg
