DOE allocates HALEU to Antares, Standard Nuclear, and ACU/Natura
The Department of Energy made conditional commitments yesterday to provide high-assay low-enriched uranium to three companies: reactor developer Antares Nuclear; fuel fabricator Standard Nuclear; and Natura Resources, which is backing Abilene Christian University’s development of a small Molten Salt Research Reactor and pursuing a commercial reactor design of its own. Following a contracting process, some of the companies “could receive their HALEU later this year.”

The discovery by Wittenberg et al. of the favorable energy balance for 3He mining on the Moon has led to a profound change in fusion reactor design studies. The replacement of tritium by 3He in the plasma has been seriously investigated. The reduced neutron fux in a D-3He reactor has substantial engineering, safety, and environmental advantages over a deuterium-tritium (D-T) reactor:
