Argonne research aims to improve nuclear fuel recycling and metal recovery
Servis
Scientists at Argonne National Laboratory are investigating a used nuclear fuel recycling technology that could lead to a scaled-down and more efficient approach to metal recovery, according to a recent news article from the lab. The research, led by Argonne radiochemist Anna Servis with funding from the Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E), could have an impact beyond the nuclear fuel cycle and improve other high-value metal processing, such as rare earth recovery, according to Argonne.
The research: Servis’s work is being carried out under ARPA-E’s CURIE (Converting UNF Radioisotopes Into Energy) program. The specific project—Radioisotope Capture Intensification Using Rotating Packed Bed Contactors—started in 2023 and is scheduled to end in January 2026.

Laser powder bed fusion (LPBF), also known as selective laser melting, of Glenn Research Copper 84 (GRCop-84), a Cr2Nb (8 at. % Cr, 4 at. % Nb) precipitation-hardened alloy, produces a fully dense, high-conductivity alloy with tensile strength (470-MPa yield and 710-MPa ultimate tensile strength) superior to other competing copper alloys. Agglomeration and coarsening of precipitates in gas atomized GRCop-84 powder occurred above a threshold of 17 μm in diameter. Area of precipitates within cross sections is consistent among powder particles of different diameters indicating a consistent atomization process. Precipitates within gas atomized powder were shown to either melt and subsequently re-precipitate as the melt pool rapidly cools or break apart during LPBF resulting in precipitates smaller than in the initial powder. Precipitate size in powder therefore does not affect precipitate size, and thus tensile strength, in LPBF GRCop-84.
