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.

Efficient heat transport and energy conversion are key factors for realizing a commercial fusion reactor. A promising method for enhancing heat transport performance and simplifying the transport system is thermosiphon. However, the maximum heat flux in the evaporation unit [namely, boiling heat transfer (BHT)] of the thermosiphon system should be improved to remove heat at high heat fluxes (>10 MW/m2). To improve BHT, we propose a new technique using a vibration material excited by boiling bubbles. In this study, we investigated the characteristics of BHT with and without the vibration material with pure water at atmospheric pressure to demonstrate our concept. We demonstrated that the vibration material enhances BHT when the vibration is synchronized with the frequency of boiling bubbles emitted from the heating surface.
