A new video explores how the WEST tokamak, run and operated by the Institute for Magnetic Fusion Research (IRFM) at the French Alternatives Energies and Atomic Energy Commission's Cadarache site near ITER, is helping to prepare for ITER operation.

WEST, for W (tungsten) Environment in Steady-state Tokamak, is the former Tore Supra, transformed with a full-tungsten, actively cooled divertor that is based on the same design and technology as the ITER tungsten divertor. Experiments at WEST allow scientists and engineers to address risks both in terms of industrial-scale manufacturing and in the operation of the components. A joint team made up of representatives of the CEA, the ITER Organization and the European Domestic Agency Fusion for Energy meets regularly to coordinate tests and share the lessons learned from the WEST experiments.

WEST is currently running a campaign of tests. Join the team in the control room here.

At the Falling Walls Science Summit in Berlin (7-9 November 2024), global experts gathered to discuss how innovation intersects with societal needs, and how resilient, sustainable systems can be created to bridge science with real-world applications. The ITER Project at the Summit by its Director-General, Pietro Barabaschi, who took part in a plenary table on "Fusion Technology:  Energy for a Sustainable Future." Other participants were moderator Norbert Holtkamp, former ITER Principal Deputy Director-General (2006-2010), Kimberly Budil, Director of the Lawrence Livermore National Laboratory; and Constantin Häfner, Managing Director at the Fraunhofer Institute for Laser Technology.

A recording of the plenary table is available at this link (beginning at 2:30:00).

Fourteen years after the start of ITER project construction, the buildings of the scientific installation are nearly complete—except for the Hot Cell Facility, whose construction is not yet underway. Equipment installation is well advanced and a number of plants are operational. ITER's drone videographer spent a week on site in October 2024, filming some of the most unique and unexpected areas. The result? A series of new aerial photos available for download from the ITER image galleries.

See the latest aerial photos here.

At least once a year, the ITER worksite is surveyed by drone from every possible angle—from the widest frame (a kilometre above the platform) to the narrowest (in and out of components staged for assembly). The results of the latest campaign in October 2024 can be viewed in the form of a five-minute video that shows the progress on site since the last time the ITER Organization published a drone video, one year ago. As the drone takes you in and around the main buildings of the ITER scientific installation you'll see the complexity of the ITER industrial plants, ongoing repairs to critical machine elements, components arriving from overseas, and the day-to-day reality for the thousands of workers involved in building ITER.

The International Atomic Energy Agency (IAEA) has just published Fusion Key Elements, a document that aims to build a common understanding of the pathway from research, development and demonstration to the commercialization of fusion energy and to chart a collaborative framework that helps to sustain and move forward fusion energy initiatives globally. The new publication, launched on 6 November 2024 at the inaugural ministerial meeting of the World Fusion Energy Group in Rome, is intended for research scientists and engineers engaged in fusion research and development, regulators, entrepreneurs or stakeholders involved in the development of fusion technology, and policymakers.

"In such a rapidly evolving sector, cultivating a common understanding of key considerations surrounding fusion energy is essential. This understanding encompasses everything from research and development to deployment and commercialization, forming the foundation for navigating the complexities and opportunities of the fusion energy landscape. This publication provides a comprehensive overview of the six key elements necessary for a shared vision in fusion energy development, thereby facilitating a unified approach to advancing fusion as a cornerstone of future energy solutions."

The DIII-D tokamak team at General Atomics (San Diego, US) is celebrating a milestone this month—achieving, and passing, the 200,000th plasma shot since the device began operating in the mid-1980s.

“While completing 200,000 shots is impressive in its own right, this achievement is far more than a mere number,” said Dr. Richard Buttery, Director of the DIII-D National Fusion Facility. “Those shots represent steady, important progress on the road to fusion energy. Each one is a challenge solved, a question answered, a career begun or progressed, or a new technology proven. In a very real sense, the history of DIII-D is a history of fusion energy research, and we are very excited for what we have planned for DIII-D in the future.”

Arriving at the French port of Fos-sur-Mer from Monfalcone, Italy, was only the first stage of transport for vacuum vessel sector 5. Next, it had to be transported by barge across the inland sea Étang de Berre (155 km²). The European-made sector successfully made the crossing on 11 October.

This month, ITER will be launching a new version of its public website. The change was compelled for technical reasons, including the need to ensure reliability for a website that has grown considerably over the past 10 years. The ITER Organization took advantage of the opportunity to update and modernize the design. Readers will see new branding, faster data retrieval, and a more dynamic interface. The navigation will remain similar to the existing site, for familiarity. Look out for the change on Saturday 19 October.

We look forward to your feedback at ITERCommunications@iter.org. 

The JT-60SA experiment has been officially recognized by Guinness World Records as the world's largest tokamak, as measured in terms of plasma volume.

On 4 September 2024 the device, built and exploited by Japan's National Institutes for Quantum and Radiological Science and Technology (QST) in conjunction with Europe's Fusion for Energy (F4E), achieved a plasma volume of 160 cubic metres, exceeding the previous world record of 100 cubic metres. A certification ceremony is planned on Saturday 19 October at the Naka Institute for Fusion Science and Technology.

JT-60SA has been designed to support the operation of ITER by following a complementary research and development program, and to investigate how best to optimize the operation of fusion power plants that are built after ITER. Further details of its experimental program are explained in the JT-60SA Research Plan.

New results from the JET tokamak offer positive news for tokamak reactor designs based on deuterium-tritium fuel, according to the European Consortium for the Development of Fusion Energy, EUROfusion.

Reporting on experiments run in deuterium-tritium (DT) during JET's record-breaking campaign in 2021—and comparing them to control experiments performed in pure deuterium (DD)—EUROfusion researchers found that future fusion power plants using DT fuel may experience fewer energy losses in their burning plasma due to instabilities than previously anticipated.

"Our goal was to study whether our earlier findings on turbulence reduction in tokamak plasmas with high-energy ions could be replicated in DT plasmas, the primary fuel for the international ITER project and future fusion power plants," explain Jeronimo Garcia (CEA-IRFM, France) and Yevgen Kazakov (LPP-ERM/KMS, Belgium), the leading authors of a paper* published in Nature Communications.  

What they found in experiments that replicated ITER conditions as closely as possible was that, with tritium in the mix, core plasma conditions actually improved. They also observed "a new beneficial state" at the edge of the plasma, without unwanted energy bursts. "Our results demonstrate that the addition of heavier tritium ions has a calming effect on the plasma, reducing turbulence," says Garcia.

This is good news for ITER and future magnetic confinement fusion reactors. Alberto Loarte, head of the ITER Science Division, had this reaction: "The results in these studies show that there is better-than-expected performance in DT plasmas compared with DD plasmas; in particular, instabilities triggered by fast particles in DT plasmas such as those expected for fast helium produced by fusion in ITER can reduce energy losses from the plasma and increase fusion performance. The studies show that if instabilities remain at low levels they actually increase performance, whereas we had formerly assumed that they would most likely decrease it. The results also show that in conditions that are relevant to ITER, it might be possible to replace the intermittent burst of plasma energy through edge localized modes (ELMs) through a much more benign continuous outflow more easily handled by the wall in ITER."

Speaking at a round table on the green energy transition at the Forum Aix-Marseille economic conference, head of the ITER Science & Integration Department Alain Becoulet said the fusion ecosystem was developing rapidly but wouldn’t be ready to meet short-term decarbonization goals.

“This is an important moment for humanity because the technology is coming out of the research laboratory and being demonstrated,” noted Becoulet. “ITER is part of a flotilla of advances in fusion research, industrial testing, and private-sector investment. This is creating the ecosystem and supply chain that will be needed to roll out this energy source on a planetary scale.”

However, Becoulet warned that even after the first fusion power plant is successfully demonstrated, it will take decades to build the thousands of plants required for a global energy transition. He added that in the meantime, broader use of conventional fission plants or new SMRs (small modular reactors) could reduce carbon emissions.

The conclusions of the day's debates and discussions will be shared at the national Cercle des Etats de la France conference, which helps shape France’s economic policies.

After Wendelstein 7-X generated a record plasma in February 2023 (lasting 8 minutes with an energy output of 1.3 gigajoules), the stellarator at the Max Planck Institute for Plasma Physics (IPP) in Greifswald, Germany, was shut down for a one-year maintenance phase.

W7-X began a new experimental phase on 10 September, after significant improvements and optimizations were made to the device (see the detail here) to improve the availability and reliability of the systems. In addition, the scientific capabilities of all systems were significantly expanded and important new observation instruments were added.

The scientific program ahead should gradually see an increase in performance parameters, specifically higher heating powers. Wendelstein 7-X is the world's largest fusion device of the stellarator type.

Through a newly launched web platform—the European Fusion Technology Marketplace—Fusion for Energy (F4E), the European Domestic Agency for ITER, and EUROfusion, a consortium of European fusion laboratories, are inviting companies to discover and benefit from fusion spinoff technologies.

The website offers companies and experts a diverse portfolio of technologies developed by F4E’s industrial partners and EUROfusion laboratories as part of work for international research programmes and projects such as: ITER, Europe's DEMOstration fusion power plant, the joint Europe/Japan JT-60SA tokamak, the International Fusion Materials Irradiation Facility (IFMIF), and the International Fusion Energy Research Center IFERC.

"Our experts work to identify their business potential and to facilitate their commercial use. Our services are offered to all companies looking for new market opportunities. We are here to help entrepreneurs, scientists and business willing to integrate fusion technologies in the development of their products," according to the marketplace website.

See all information here.

Fusion for Energy (F4E) has opened a Call of Expressions of Interest for collaboration with private sector fusion initiatives. Its aim is "to support the growth and success of Europe's private sector and foster innovative collaborations that will drive the future of fusion energy."

Interested private sector fusion initiatives must: 1) be established with the purpose of developing a fusion device or technologies specific to fusion (or have a business unit dedicated to this goal); 2) indicate the areas of interest for collaboration which may be fusion-related technical areas, or non-technical (e.g., supply chain, legal, etc.); 3) and have their centre of interest or main operations in an F4E Member State (currently the 27 EU Member States).

If there is a mutual interest to cooperate, an agreement will be signed to allow collaboration in fields to be defined jointly such as, not limited to: exchange of knowledge, information and experience, expertise in fusion technologies, fusion supply chain, corporate governance, scientific analysis etc. No transfer of funds from F4E is foreseen under the terms of the call.

Manufactured by Hyundai Heavy Industries, the fourth and last vacuum vessel sector procured by Korea took to the sea on 24 August. The massive 440-tonne component will travel for approximately one month before reaching the Mediterranean. Due to the situation in the Horn of Africa waters, the ship will take the long way home, rounding the Cape of Good Hope at the southern tip of the African continent and sailing all the way north to the Strait of Gibraltar to enter the Mediterranean.

Pre-registration ends on 10 September 2024 for the 13th ITER International School, which will be held from 9 to 13 December 2024 in Nagoya hosted by National Institute for Fusion Science (NIFS), Japan. The theme of the 13th School is "Magnetic Fusion Diagnostics and Data Science."

Diagnostics are key to the achievement of ITER fusion power demonstration goals and they require the application of a wide range of techniques. But diagnostics are not enough to ensure ITER's success; only through advanced analysis of the data they provide will it be possible to guide the experiments towards their fusion power goals. It is timely to address these multidisciplinary areas in the ITER school.
