Researchers at Oak Ridge National Laboratory developed a continuous extruder for fusion fuel and are advancing state-of-the-art fueling and plasma control for the ITER international fusion reactor now under construction in France. US ITER is managed by Oak Ridge National Laboratory for the U.S. Department of Energy. Reliable, high-speed continuous fueling is essential for ITER […]
Computer codes calculate nuclear heating, neutron radiation damage and activation of fusion reactor materials. ―Lynne Degitz US ITER researchers at the University of Wisconsin and Oak Ridge National Laboratory are developing advanced processes to assess ITER’s unique tokamak components and materials in the presence of the tremendous amount of neutron flux and energy released by […]
―Agatha Bardoel Using a cryogenic deuterium pellet injector installed on the DIII-D tokamak operated for the Department of Energy Office of Science by General Atomics in San Diego, ORNL researchers and collaborators were able to fire millimeter-sized frozen deuterium pellets into ultra-hot plasma at a rate of 60 times per second. The results demonstrate that […]
―Agatha Bardoel Oak Ridge National Laboratory’s Fusion Pellet Fueling Lab has been at the center of design and testing of plasma fueling systems for tokamak research applications for decades. Since the mid-1970s, lab researchers have been designing, testing, and contributing hardware for fusion magnetic confinement experiments here in the United States and around the world. […]
