Addyson Barnes
Addyson Barnes received her B.S. in Chemical Engineering from the University of Idaho in 2020 and has since supported Idaho National Laboratory in the Nuclear Science & Technology directorate. Her current work primarily focuses on solvent extraction processes supporting used nuclear fuel reprocessing with nonproliferation considerations. This includes the operation of solvent extraction equipment including centrifugal contactors, pulsed columns, and mixer settlers, flowsheet modeling and design, and maintaining knowledge in relevant fundamental chemistry. This is all applied in multiple environments including radiological, non-radiological, and benchtop and pilot-scale facilities, all requiring the use of ancillary systems. Additionally, Barnes supports projects for the U.S. Office of Nuclear Energy’s Material Recovery and Waste Form Development program, looking at alternative methods for decladding nuclear fuel, and she supports process design for new solvent extraction-based systems planned for construction at INL. Other projects in her portfolio have supported the rare earth industry, investigating novel solvent extraction systems that may be applied for recovery of critical materials. Currently, Barnes is pursuing a PhD in Chemical Engineering with her research looking at alternative extractants proposed in nuclear fuel aqueous reprocessing systems, supporting the National Nuclear Security Administration’s Nonproliferation Stewardship Program.
