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 rate of tritium recovery from liquid lithium by molten salt extraction was measured. The mass balance of tritium was always good during extraction and the overall mass transfer coefficient was evaluated. The dependences of the mass transfer coefficient on salt and temperature are explained by considering the predominant resistence to the mass transfer in the salt phase. The semi-empirical equation is given by KM* (cm/s) = 2.2×10−4(T(K)/µsalt (cp))1/2 where µsalt is the viscosity of salt.
The reference scheme of molten salt extraction is re-evaluated with the newly obtained data. Not only from the thermodynamic but also from the kinetic points of view, it is shown that a design goal of the tritium concentration of 1 wppm in lithium would be reached by combining a reasonable number of extractor units. A mixer-settler with mechanical stirrer may be sufficient for the extractor.
