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.

Power quality is analyzed for the poloidal field (PF) power supply system of the Experimental Advanced Superconducting Tokamak (EAST) device. It is found that the power quality is quite different when the four-quarter PF power system is working in different operation modes. The (6k±1)’th (k is the odd number) harmonics are dominant during the electricity-cost phase while the (6k±1)’th (k is the even number) harmonics exist abundantly during the electricity-generation stage. In addition, fast Fourier transform as the data analysis method is applied to process harmonics and interharmonics. The experimental results present the characteristics of waveform and of current and power, and they show the emission features of harmonics and interharmonics, which leads to the conclusion that the energy of interharmonics and spectrum leakage caused by the harmonic clustering algorithm is recovered to an integer or that the picket fence effect results in the spectrum leakage of interharmonics.
