Researchers use one-of-a-kind expertise and capabilities to test fuels of tomorrow
At the Idaho National Laboratory Hot Fuel Examination Facility, containment box operator Jake Maupin moves a manipulator arm into position around a pencil-thin nuclear fuel rod. He is preparing for a procedure that he and his colleagues have practiced repeatedly in anticipation of this moment in the hot cell.

Understanding the origin of asymmetries, either in plasma flows reaching the divertor region or in plasma emissivity from the confined volume, is a question of great interest in magnetic confined plasma research.In the TJ-II stellarator, a set of bolometer systems distributed around the vacuum chamber has been installed to monitor up-down and in-out radiation asymmetries that are observed in transitions to different confinement regimes. Although plasma emissivity is a complex magnitude, a comparison of signals from twin detectors placed at selected positions may be of help to distinguish between the different causes of asymmetry. Moreover, this is a nonperturbing method that is especially appropriate when plasma wall clearance is small.
