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 […]
The ITER experimental fusion facility, now under construction in southern France, will use 100,000 kilometers of low-temperature, helium-cooled superconducting wire to generate the immense toroidal magnetic fields needed to confine 150 million degree Celsius plasma inside a tokamak machine.
―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. […]
