Putting welding tools to the test

Under a new agreement signed in June 2026, ITER and the Chinese Academy of Sciences, Institute of Plasma Physics (ASIPP) have launched a joint postdoctoral training program that will give early-career researchers the opportunity to conduct fusion research at both institutions under the supervision of experts from China and ITER. 

ASIPP will be creating a series of postdoctoral positions focused on research topics of mutual interest to the ITER Organization and ASIPP. The selected researchers will be employed by ASIPP and jointly supervised by experts from both organizations. The positions are offered for a two-year term, with research carried out both at ITER and at ASIPP headquarters. 

These postdoctoral positions are now open to application by Chinese nationals and nationals of other ITER Members. Further information, including application details, is available in Chinese and English here.

French YouTuber Amixem recently visited ITER for a video exploring three of France’s most “off-limit” locations, alongside secret areas of the Eiffel Tower and the French presidential plane. Filmed earlier this year, the visit included a tour of the Assembly Hall with project engineer Raphael Tieulent and the tokamak pit with assembly facility coordinator Isabelle Gentili.

The video attracted more than two million views within its first 24 hours online and has since surpassed four million views.

Drawing a parallel between the Eiffel Tower and ITER, Amixem remarked: “[The tower] was a kind of technological demonstration, a way of saying to the world: look at what we can do in our time. And I think ITER is exactly the same.”

Amixem, whose real name is Maxime Chabroud, launched his YouTube channel in 2012 and today has around 9.5 million subscribers. According to vidIQ, his videos have generated more than 4.5 billion views. While he first gained popularity through gaming content, his channel has since expanded to include humour, challenges, travel, experiments, and large-scale documentary-style productions.

The full video is available at: https://www.youtube.com/watch?v=l1bW68QJMUI. The video is in French and includes English subtitles as well as an automatically dubbed English audio track.

The 16th ITER International School on the topic of "Tokamaks as Fusion Reactors" will take place from 30 November 2026 to 4 December 2026. The school is jointly organized by Institute for Plasma Research (IPR), Bhat, Gandhinagar, Gujarat, and The International Center for Theoretical Sciences – Tata Institute of Fundamental Research (ICTS-TIFR), Bengaluru, in collaboration with ITER Organization and Aix Marseille University, France. The school will be hosted at ICTS-TIFR, Bengaluru. 

The ITER International School aims to prepare young scientists and engineers for working in the field of nuclear fusion and in research applications associated with the ITER project. The 16th edition will cover a broad range of topics related to tokamak fusion reactors’ physics and technologies, such as plasma confinement, heat and particle exhaust, integrated control and operation, integrated modelling and digital twins, plasma-materials interaction, superconducting magnets technology, neutron shielding, and tritium breeding. 

Registration has been extended through 3 September. For all information see this website. 

The Joint European Torus (JET) operated for 40 years before entering decommissioning in 2023. It was the last tokamak capable of operating with deuterium-tritium (D-T) fuel until devices like ITER begin their own D-T research, which makes the datasets generated in JET’s final campaigns effectively irreplaceable. 

The outcome of its final experiments between 2022 and 2023 was presented as an Overview contribution to the last IAEA Fusion Energy Conference in Chengdu and was recently published in Nuclear Fusion. These results are already validating predictive models, contributing to shared international databases, and informing the design of first-of-a-kind fusion power plants. 

The results speak for themselves. JET set a new fusion energy record of 69 MJ in tritium-rich hybrid plasmas and achieved long-pulse H-mode operation up to 60 seconds. The team also demonstrated ITER-relevant integrated scenarios and generated critical data informing the pellet injection mechanisms for ITER’s disruption mitigation system. JET’s comprehensive fuel-retention studies will also act as a precedent for how ITER may track and manage its tritium inventory.

Beyond the physics, JET’s final years leave behind decades of operational experience in handling tritium and nuclear-grade components will directly shape how ITER and future power plants are safely operated.

JET’s results are further described in an article published by EUROfusion and in the newly published scientific paper.
