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.

An experiment on the separation of hydrogen isotopes has been carried out by using a thermal diffusion column with a “cryogenic-wall” cooled by liquid nitrogen. The separation factor was compared with that of a ordinary column cooled by water, and the separation factor for the “cryogenic-wall” column is higher than that for the “water cooled wall” column. Moreover, the separation factor obtained by a 473 K operation of the hot wire in the “cryogenic-wall” system was found to be greater than that by 1073 K operation. Probably because the isotopic exchange reaction between H2 and D2 was suppressed in 473 K operation; there was no HD component observed in this case, while an equilibrium amount of HD component was immediately detected in 1073 K operation.
