“They Just Delivered the Heart of a Star”: China Ships 50-Foot Fusion Beast to France and Scientists Say “This Changes Everything”

The delivery of a monumental component from China to France marks a significant step in the global pursuit of nuclear fusion energy. The ambitious ITER project, stationed in the south of France, recently received a critical piece of technology from China, furthering its mission to harness the power of the stars. This collaboration brings us closer to the ultimate energy goal, promising a future of abundant, clean energy. As countries worldwide contribute to this monumental effort, each step forward is a testament to international cooperation and scientific advancement.

China’s Engineering Marvel Delivered

In April 2025, China confirmed the delivery of a crucial component for the ITER fusion reactor, currently under construction in Cadarache, France. This component, known as the Correction Coil In-Cryostat Feeder, plays a pivotal role in the magnetic system of the reactor. Each unit measures approximately 49 feet in diameter and 10 feet in height, collectively weighing around 3.5 million pounds. These feeders ensure the superconducting magnets are precisely powered, cooled, and controlled, even acting as a safety valve during instability.

The delivery represents a major logistical and engineering feat, showcasing China’s capability in high-tech manufacturing. Developed by the Institute of Plasma Physics at the Chinese Academy of Sciences, this technology results from over 20 years of collaborative research. China’s significant investment in this project, despite its domestic nuclear restrictions, underscores its commitment to advancing global energy solutions.

The Backbone of the Magnetic Enclosure

The component provided by China is far more than a simple “magnet cooler.” It ensures the smooth transmission of control signals, maintains magnetic stability of the plasma, and secures the energy flow. Essentially, it forms the backbone of the magnetic enclosure crucial for the reactor’s operation. Each component underwent rigorous testing in China to ensure precision, as any deviation in temperature or power supply could jeopardize the entire experiment.

According to Lu Kun, Deputy Director of the ASIPP, this is the most complex system ever supplied by China to the ITER project. Achieving this required collaboration with over 140 institutions across 50 countries, highlighting the global scale and ambition of this scientific endeavor.

A Global Effort to Harness Star Power

The ITER project, short for International Thermonuclear Experimental Reactor, is supported by seven global partners: the European Union, China, the United States, Russia, Japan, India, and South Korea. This extensive collaboration aims to recreate the energy of the Sun on Earth, with a budget exceeding $24 billion. While costly, the potential reward—a sustainable energy source—justifies the investment.

Like our Sun, the reactor will generate energy through nuclear fusion, combining hydrogen nuclei to produce heat and light. This process emits no CO₂ and produces no long-lived radioactive waste. Unlike current nuclear fission reactors, fusion poses no risk of runaway reactions or explosions. Instead, it requires extreme conditions to initiate but becomes inert if these conditions are disrupted.

Lighting the Plasma: The Next Milestone

Construction at Cadarache progresses steadily, with the goal of producing the first plasma in a few years. This milestone will pave the way for achieving net energy production—generating more energy than consumed to initiate the reaction. If successful, this would be a historic first. Existing experimental reactors, like the WEST tokamak in France, have already set records, but ITER aims for industrial-scale power outputs capable of powering entire cities.

This ambitious target sets ITER apart, aiming for a commercial fusion breakthrough. The potential success of this project represents a monumental leap forward in energy technology, promising a future where energy is clean, abundant, and accessible to all.

The International Race Toward Fusion

China’s involvement in ITER is part of a broader strategy to lead in fusion technology. Its own reactor, EAST, previously set records for plasma duration. As a key player in ITER, China continues to share technology and expertise, training engineers from other nations. The ITER project symbolizes scientific diplomacy and could become the cornerstone of a global energy transition free from CO₂ emissions.

The world watches as this puzzle of immense scale comes together, each piece meticulously placed to create a future where energy is limitless. As these advancements unfold, one wonders: how will the successful harnessing of fusion energy reshape our global landscape?
