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.

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.

Fred Mills of The B1M construction channel on YouTube returned to the ITER site this summer to report on ITER after a first video produced in 2022 amassed 4 million views.

In a sleekly produced 30-minute feature he reminds his audience of the potential of nuclear fusion ... and the many challenges. He recounts how the international collaboration got its start in the 1980s, how facility construction began in 2010, and how today, in the context of challenges in assembling the one-million-component machine, the teams are collaborating to solve engineering challenges and deliver solutions.

He calls ITER "the planet's most monumental build." The scale of the ambition, the extent of the engineering, the attention to detail is honestly mind-blowing," he says. "It’s hard to think that the place where I’m standing could one become the birthplace of a new form of energy. This spot could literally see the start of something that could change the world." 

Views have already topped 450,000. See the video on YouTube here.

A 440-tonne sector of the ITER vacuum vessel completed by HD Hyundai Heavy Industries Co., Ltd was transported to the Korean port of Mipo on Friday 23 August. It shipped on 24 August and is expected to reach ITER next month.

This is the fourth and final vacuum vessel sector expected from Korea. Three other sectors arrived respectively in 2020, 2021, and 2022.

The torus-shaped ITER vacuum vessel will be formed from nine vacuum vessel sectors. Five sectors are expected from the European Domestic Agency including one, sector #5, later this year.

The Fusion Industry Association has released its 2024 Global Fusion Industry Report. The report, which surveyed 45 companies, found that the fusion industry has attracted over USD 7.1 billion in investment, with USD 900 million in new funds since last year. Total public funding increased by 57% in the last 12 months to USD 426 million, showing that governments increasingly see public-private partnerships as central to making commercial fusion a reality. It also showed the United States leading commercial fusion, with 25 companies, followed by the United Kingdom, Germany, Japan, and China. Additionally, employment in private fusion firms grew by 34% to over 4,000.
