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.

In nuclear fusion reactor facilities, the multi-confinement system and the air detritiation system (ADS) are very important to prevent tritium leaking to the environment. A high-performance tritium oxidation catalyst is strongly required in the ADS. In this study, the air resistance and catalytic performance of honeycomb detritiation catalysts are investigated. Then, the honeycomb catalysts are applied in a glove-box detritiation system as well as in an ADS, and the detritiation performance is tested with tritium. Honeycomb catalysts have a much lower air resistance and an excellent scale-up effect due to the behavior of laminar flow. Thus, the honeycomb catalyst increases the reaction space velocity by nearly 100 times without decreasing the conversion rate of H2. Even at an extremely low tritium concentration, the honeycomb catalyst transforms tritium over 95% into tritiated water. In short, Pt-loaded honeycomb catalysts have a huge advantage in and broad potential for air detritiation.
