University of Utah
The University of Utah will research a pyrochemical process for efficiently converting UNF to a uranium/transuranic (U/TRU) product suitable for sodium-cooled fast reactors or molten-salt fueled reactors. This process is based on two key separations steps that can occur in a single reaction vessel: dissolution of oxide UNF in molten lithium chloride (LiCl)-potassium chloride (KCl) salt and electrochemical recovery of U/TRU metal on a cathode.

Energetics Technology Center
Energetics Technology Center will build upon past successes with co-deposition experiments using palladium, lithium, and heavy water together to create an environment in which LENR can occur. These electrolysis experiments decrease the distance from the cathode (location of LENR) to an electronic detector capable of detecting nuclear reaction products to give these experiments the best chance at reliably detecting nuclear reactions, if they are present.

Argonne National Laboratory (ANL)
Argonne National Laboratory (ANL) will research an electrochemical oxide reduction (OR) process that meets CURIE’s cost and waste metrics for a pyroprocessing facility. Electrochemical OR is a single-step process that converts used oxide fuels to metal that can be electrorefined to produce uranium/transuranic (U/TRU) alloys suitable for fabrication into advanced reactor fuels. However, current process inefficiencies result in non-uniform and incomplete conversion to metal, long process times, and large waste volumes.
