ANS joins others in seeking to discuss SNF/HLW impasse
The American Nuclear Society joined seven other organizations to send a letter to Energy Secretary Christopher Wright on July 8, asking to meet with him to discuss “the restoration of a highly functioning program to meet DOE’s legal responsibility to manage and dispose of the nation’s commercial and legacy defense spent nuclear fuel (SNF) and high-level radioactive waste (HLW).”

Some open traps, like GOL-3, may be heated by axial electron beams. Since the heating is turbulent, it is associated with anomalous resistivity, so that the reverse induction current is pushed out to flow in the shell plasma along the beam edge. It is shown that such complicated distribution of axial current in equilibrium causes exponential amplification along the trap of any initial (at entrance) azimuthal modulation of the beam current density. As a result, the shape of the beam cross-section develops features like spiral arms, etc. at the end-plate, even if its shape was nearly circular at the entrance. Amplification occurs whenever there is an off-axis extremum on the radial distribution of the axial current density.
