Visits to our Corporate Members’ labs and offices are a huge highlight for us at #AIAA. We enjoyed our time this week at General Atomics, especially AIAA CEO Dan Dumbacher's meeting with Dr. Vivek Lall, Chief Executive, General Atomics Global Corporation. We saw the reaction chamber of the DIII-D, an experimental tokamak fusion reactor operated by General Atomics in San Diego, which has been used in research since it was completed in the late 1980s. We learned that the characteristic torus-shaped chamber is clad with graphite to help withstand the extreme heat. Thank you for such a stimulating learning experience along with an energizing idea exchange. #AIAA

Which #tokamak and #stellarator #fusion questions has the #JOREK code community been working on in the last few years? Find a full review here, just accepted for publication in the journal Nuclear Fusion: https://lnkd.in/dk8kJ2t4 High level results include studies of benign termination of runaway electron beams, vertical foce mitigation via massive impurity injection, turbulence and tungsten transport in plasmas with external perturbation fields, neutral particle dynamics in the scrape-off layer, flux pumping in the plasma core, and first advanced stellarator applications. For major model developments standing out are the coupling to the #CARIDDI code regarding the interaction with volumetric 3D wall structures, an establishment of advanced models for the scrape-off layer including kinetic neutrals and impurities, implementation of advanced runaway electron models, and the formulation of fully kinetic ITG/TEM models.

The Korea Institute of Fusion Energy’s (KFE) Korea Superconducting Tokamak Advanced Research (KSTAR) fusion reactor has reached temperatures seven times that of the Sun’s core. The researchers managed to maintain temperatures of 212 degrees Fahrenheit for 48 seconds. They also maintained the reactor's high confinement mode for over 100 seconds. Creating technology that can maintain high-temperature and high-density plasmas for extended periods is crucial for fusion. #technology #innovation #fusion https://lnkd.in/gQ-i3N6y

⚛️First observation of how fusion keeps itself hot boosts confidence in ITER Organization and future fusion power plants. Researchers from the EUROfusion consortium announced scientific results from their record-breaking experimental campaign at the Joint European Torus (JET) fusion facility in 2021. ➡BSC researchers Dani Gallart Escolà, PhD and Mervi Mantsinen Fusion Group BSC are involved in 5 of the 15 papers in a Special Issue, including one BSC fist author paper by Mantsinen. 🗣"It is great to see the publication of this Special Issue. It is a culmination of years of research in the forefront of the #fusion field and provides key new information for ITER and future fusion reactors."
At the IAEA's FEC2023 conference, the European consortium of fusion researchers EUROfusion presents the first-ever direct observations of how fusion keeps itself hot, boosting confidence in ITER and other future fusion devices like DEMO! This result is part of a series of publications about the 2021 experiments at the Joint European Torus (JET) that fused deuterium and tritium, the planned fuel mix for future fusion power plants. https://lnkd.in/e3dBMfjf ITER Organization | Fusion for Energy | International Atomic Energy Agency (IAEA) | European Commission

⚡ Tokamak with Reactor Technology (TRT) is being developed as a full-scale prototype of a future fusion reactor/neutron source. It is designed to study the behavior of plasma in quasi-stationary modes close to ignition, research and development of various methods for additional plasma heating, fuel supply, blanket technologies, development of new diagnostics operating in high neutron fluxes, and development of tritium technology. ⚡ “Currently there is a lot of construction going on at the site, just like there was in the 70s and 80s, and it will develop even more. The construction of the Tokamak with Reactor Technologies will lead to the restoration of Russia’s ideological and technological leadership in the field of controlled thermonuclear fusion,” said Kirill Ilyin, Director General of the State Research Center of the Russian Federation TRINITI. https://lnkd.in/e2fwpVnV 🌷🌷🌷

CFS was spun out of MIT in 2018 to commercialize fusion power using a breakthrough magnet design. Both CFS and Realta are working to deploy reactors that use powerful magnetic fields to hold burning plasma in place so that hydrogen nuclei can fuse, a process that releases immense amounts of heat. CFS’s reactor is what’s known as a tokamak, which coerces plasma into a doughnut-like shape. HTS (high temperature superconductors) https://lnkd.in/djdaKp9S

To make fusion energy, we are going to hold a star in a magnetic bottle. Even if that part was easy, we still need a place to create and hold the bottle itself. Figuring out a suitable plasma-facing wall is where material science has a huge impact on fusion energy research. In recent work from Shawn Zamperini and colleagues, they explore the performance of a silicon carbide (SiC) wall through modeling of DIII-D scenarios. SiC is a remarkable material: it can withstand the neutron environment of a reactor, it can operate at incredibly high temperatures, and it doesn't absorb tritium under these conditions. The results indicate that switching DIII-D from a graphite wall to a SiC wall would lower the effective "wall material pollution" in the plasma. In a somewhat rare occurrence, the viability of SiC actually improves as it scales to a reactor because a reactor wall will be much higher temperature than a research device wall, bringing SiC into its sweet spot for performance. This work brings together authors from General Atomics, Fusion and Fission at ORNL, University of Tennessee, Knoxville, University of Toronto, and UC San Diego. S.
