DOE-NE’s newest fuel consortium includes defense from antitrust laws
The Department of Energy's Office of Nuclear Energy is setting up a nuclear fuel Defense Production Act Consortium that will seek voluntary agreements with interested companies “to increase fuel availability, provide more access to reliable power, and end America’s reliance on foreign sources of enriched uranium and critical materials needed to power the nation’s nuclear renaissance.” According to an August 22 DOE press release, the plan invokes the Defense Production Act (DPA) to give consortium members “defense from antitrust laws when certain criteria are met” and “allow industry consultation to develop plans of action.” DOE-NE is looking for interested companies to join the consortium ahead of its first meeting, scheduled for October 14.

Alpha healing, alpha containment, and alpha stabilization effects are studied in the fusion ignition experiment IGNITEX. The IGNITEX device offers the possibility of producing fusion-ignited plasmas with ohmic heating alone. It is shown here that operating regimes with high probability for ignition and simplicity of operation are possible in IGNITEX. Time-dependent simulations showing the ohmic heating and alpha healing coupling through the discharge are presented. The characteristics for alpha transport with magnetic field perturbations are analyzed in detail using Monte-Carlo techniques. The stability of internal MHD modes and the interaction with alpha particles in the inner confinement region of ignited plasmas is studied. Specifically, the stability of resistive internal kinks, ideal internal kinks, and fishbones is presented. It is shown that a quiescent regime of operation is possible during the ignited phase in IGNITEX. Because of its ample ignition margin, its high alpha containment, and the possibility of operation far from marginal stability and the possibility of ignition operation with quiescent regimes in the inner region of the plasma, it is concluded that the IGNITEX device can produce fusion-ignited plasmas in a simple manner.
