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.

Existence of non-axisymmetric electrostatic potential in the plug region of GAMMA10 yields radial losses of ions in thermal barrier cell. Detailed behavior of ions in non-axisymmetric potential and its contribution to the transport in GAMMA10 is not investigated in details. In this study, by modeling the plug potential and the actual magnetic field in the end-mirror cell and estimating the amount of radial shifts of ions by following ion drift motion per bounce, the resultant mapping equation is used to analyze the orbits and diffusion of ions. Especially, the stability of orbits about the first and second order fixed points is studied and the diffusion due to chaotic orbits is estimated.
