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.

The commercial viability of high field tokamaks is critically dependent upon the development of high field, high energy superconducting magnets. In this paper, superconducting magnet development requirements are discussed in terms of superconducting materials, structural materials and magnet engineering. Superconducting and structural materials are evaluated for processing techniques, properties and applicability to large scale magnets. Both conventional low Tc and high Tc ceramic superconductors are considered. For structural materials, cryogenic steels as well as fiber reinforced composite materials are discussed. The application of advanced materials, in particular high Tc superconductors and fiber reinforced composites, poses unique engineering problems that must be addressed. These problems are exacerbated by the very large stored energy inherent to any large high field magnet. Potential solutions are analyzed and areas of uncertainty are identified. A 30 year development program leading to a 24 Tesla toroidal field coil for a commercial reactor is outlined.
