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.

The absolute collimator currently in service at the DIII-D NB injection system has experienced localized melting and damage. As part of the DIII-D 210-deg beamline co-counter conversion, a new absolute collimator was needed, and the opportunity to resolve melting was found on the off-axis beamline configuration. The pulsed high heat flux and uneven distribution of the heat loads required the aperture surface to be axially extended to spread out and reduce the surface heat flux. Geometric sculpting of the absolute collimator aperture based on the baseline dimension was performed using ANSYS CFX software. The reshaped absolute collimator aperture surface reduces the impinged heat flux to below ~4 MW/m2. Two interchangeable inserts are designed to occupy the high heat flux region for mitigating the thermal-induced stresses. The design achieves the objective of 6-s pulse lengths with 10-min repetition rates using the original peripheral conduit cooling system in the new collimator with minor changes.
