From June 30th to July 4th, Hernán Domingo attended the 14th International ITER School on Integrated Modelling in Magnetic Fusion Plasmas, held in Aix-en-Provence, France. The event, organized primarily by Aix-Marseille University, CEA and ITER Organization , brought together over 200 participants from diverse backgrounds, all sharing a common eagerness to learn more about nuclear fusion and integrated modelling.

Our PhD student, Hernán, had the opportunity to present a poster on Alya4fusion, our latest project focused on nuclear fusion reactor simulation and integrated modelling.

The 25th Topical Conference on Radio-Frequency Power in Plasmas took place from 19 to 22 May 2025 and attracted more than 130 participants. Our group leader, Mervi Mantsinen, delivered an invited talk at this conference reviewing key milestones from four decades of Ion Cyclotron Range of Frequencies (ICRF) physics on the Joint European Torus (JET), highlighting its significant contributions to fusion research and implications for future reactors.

JET, Europe’s leading tokamak device, has achieved exceptional performance surpassing its design specifications, operating with magnetic fields of up to 4 T, plasma currents of 7 MA, and auxiliary heating powers totalling 37 MW. Its versatile ICRF system, with a frequency range of 25–56 MHz, has enabled a wide array of heating and current drive experiments.

JOREK code meeting in Naples

Pizzofalcone lookout, Naples, just above the meeting location.

From May 12 to 16, the 2025 JOREK general meeting was held in Naples, Italy. Nicola Isernia and colleagues from the Federico II University of Naples organized the logistics for hosting the meeting. The meeting was held in the Federico II Congress Center, via Partenope, 36, just in front of the sea and below the wonderful lookout of Pizzofalcone and very close to the historical city center of Naples.

From our research group, Federico Cipolletta, participated in the event to share the work he performed in the JOREK code.

From April 7th through 10th, Fusion Group Researcher Ezequiel Goldberg participated in the Fusion Neutronics Meeting 2025: ITER and beyond, organised this year by the “Tecnologías de Fisión, Fusión y Fuentes de Irradiación” group (TECFIR) from UNED with the support of ITER and Oak Ridge National Laboratory (ORNL). The meeting venue was the Facultad de Educación building at the UNED campus in Madrid, Spain, and the event gathered experts from around the world to discuss recent advances and future directions in fusion neutronics.

On the event’s third day, Ezequiel presented the work “Neutron flux in IFMIF-DONES operation room: a comparison between Monte Carlo and deterministic codes.” The presentation focused on recent advancements in NEUTRO, the neutronics module of Alya, developed as part of the Alya4Fusion initiative. NEUTRO simulates neutron flux distribution and the resulting interactions with reactor materials, key to improving the accuracy and safety of fusion reactor designs.

The ITER Business Forum 2025 (IBF) was held during 23rd–25th April in the sunny city of Marseille, France. This Forum is designed to attract the global industry involved in the realization of fusion energy, from the supply chain to companies and startups. This is a great opportunity to connect and explore new collaborations in the industry ecosystem.

The Barcelona Supercomputing Center participated with representatives of the Fusion Group: Mervi Mantsinen, Federico Cipolletta, and Dani Gallart. Moreover, BSC members Andrés José Román from the Innovation and Business Development department, and Mario Ejarque and Sara Ibáñez from the Communications department, also participated, providing support in several relevant aspects. Special mention to María Paz Baghetti, our Dissemination Officer, who coordinated the preparations of our participation to the event.
