2024 was a difficult year for Iter (International Thermonuclear Experimental Reactor<\/em>). This ambitious \u00a0nuclear fusion reactor\u00a0 is under construction in the French town of Cadarache by an international consortium \u00a0led by the European Union\u00a0. Initially conceived in 2006, the project officially commenced in 2007, but the assembly of this colossal machine didn\u2019t kick off until 2020.<\/p>\n

<\/p>\n

The original timeline established by Eurofusion\u2014the institution responsible for promoting and facilitating the scientific research necessary for the European Nuclear Fusion Plan\u2014set the completion of the assembly for 2025. However, that same year was slated to mark another vital milestone: the initiation of \u00a0plasma tests\u00a0. Subsequent milestones were scheduled for 2028, when Iter engineers would begin low power operations utilizing hydrogen and helium, followed by the first high-power experiments in 2032 with the same gases.<\/p>\n

<\/p>\n

Boldly, it was projected that by 2035, Iter would undertake high-power tests with \u00a0deuterium\u00a0 and \u00a0tritium\u00a0. Fast forward to 2040, and this experimental reactor was expected to demonstrate the energy profitability of nuclear fusion. However, these timelines have faced significant delays. In 2022, the French Nuclear Safety Authority (ASN) flagged multiple technical irregularities in the vacuum chamber sectors, prompting the Iter organization to respond appropriately by forming a working group to address ASN\u2019s supplementary requests and continue advancing the assembly of the \u00a0Tokamak\u00a0.<\/p>\n

Iter’s Technical Challenges Are Unprecedented<\/h2>\n

The assembly of such a complex machine is anything but straightforward. The vacuum chamber alone weighs \u00a08,000 tons\u00a0 and is constructed from stainless steel and boron, requiring a hermetic seal. Engineers have faced incredibly strict local tolerances of just \u00a00.1%\u00a0, compounded by the chamber’s intricate shape and the use of plates up to \u00a060 mm thick\u00a0. To tackle these challenges, technicians have resorted to cutting-edge technologies, such as \u00a0Electron Beam Welding\u00a0\u2014a technique that utilizes an electron beam for welding\u2014or advanced AI models specifically designed to identify weld defects in the chamber.<\/p>\n

The \u00a0COVID-19 pandemic\u00a0, which peaked sharply during 2020 and 2021, alongside the technical challenges stemming from the unprecedented nature of many components, has caused \u00a0significant delays\u00a0 in the main milestones of this project. Nonetheless, the current updated timeline proposes several key dates worth noting.<\/p>\n
<\/p>\n

In 2039, Iter will be able to undertake high-power tests with deuterium and tritium.<\/p>\n<\/p><\/div>\n<\/div>\n
By 2034, the first experiments in the reactor are anticipated; in 2036, the magnetic system responsible for plasma confinement will be tested; and in 2039, Iter aims to start high-power tests with deuterium and tritium\u2014this last milestone was initially expected in 2035.<\/p>\n
 <\/p>\n
Despite these challenges, assembly progress on Iter has advanced well over the past year. The cover image of this article showcases two of the substantial sectors of the vacuum chamber; however, one of the \u00a0milestones achieved\u00a0 this year occurred in May. The \u00a0superconductor magnets\u00a0 installed on the exterior of the vacuum chamber bear the critical responsibility of generating the magnetic field required to confine the plasma internally while simultaneously controlling and stabilizing it.<\/p>\n
<\/p>\n
These magnets, weighing around \u00a010,000 tons\u00a0, are manufactured from an alloy of niobium and tin or niobium and titanium. They achieve superconductivity when cooled with \u00a0supercritical helium\u00a0 to an astounding temperature of \u00a0-269 \u00baC\u00a0. This extreme requirement justifies the need for a powerful cooling system, which has been meticulously planned for Iter by European collaborators. In the construction of this experimental nuclear fusion reactor, contributions have come from the US, Russia, China, India, South Korea, Japan, and the UK, with the refrigeration plant developed by \u00a0Fusion for Energy (F4E)\u00a0, the European Union\u2019s organization coordinating its contribution to Iter, in collaboration with the French company \u00a0Air Liquide\u00a0.<\/p>\n

Superconductor magnets acquire superconductivity when they reach a temperature of -269 \u00baC.<\/p>\n<\/p><\/div>\n<\/div>\n
This cryogenic facility will provide liquid helium at \u00a04.5 Kelvin (-269 \u00b0C)\u00a0 to the superconductor magnets and cryobombs, as well as gaseous helium at \u00a080 Kelvin (-193 \u00baC)\u00a0 to thermal shields, which are crucial for protecting vital components like superconductor magnets from the heat emitted by the confined plasma. Cryobombs work to eliminate gases from within the vacuum chamber, necessitating operation at extremely low temperatures. Thermal shields ensure protection for critical reactor elements from plasma heat exposure.<\/p>\n
<\/p>\n
Iter’s cryogenic plant spans an area comparable to a \u00a0football field\u00a0 (over \u00a07,100 m\u00b2\u00a0) and houses several \u00a026-meter high storage tanks\u00a0. Such dimensions testify to the enormity of this vital installation, without which nuclear fusion would be utterly infeasible. A statement from F4E manager \u00a0Grigory Kouzmenko\u00a0 inspires optimism for Iter’s future, declaring, “We have entered the most exciting phase of the project, in which all efforts of previous years are finally coming to fruition, benefiting from the collaboration and trust among all parties involved.”<\/p>\n
