Amanda Youker is a chemist in the Chemical and Fuel Cycle Technologies Division. Dr. Youker has been working to accelerate the US production of Mo-99 using non HEU-based methodologies for the past 10 years. Her research efforts focus on the preparation of uranyl nitrate and sulfate solutions, Mo-99 separation and recovery processes, and precipitation mitigation in irradiated uranium solutions. Dr. Youker serves as the program manager for NNSA’s Material Management & Minimization Mo-99 Program.
Dr. Youker also manages the Radiochemistry group within Argonne’s Chemical and Fuel Cycle Technologies Division. In addition to Mo-99, the Radiochemistry group also participates in R&D activities related to other medical isotopes such as Cu-67 and Sc-47. Additional experimental work in the Radiochemistry group focuses on the separation of actinides from fission products using novel solvent extraction and ion exchange processes.
Dr. Youker received her B.S. in chemistry from Benedictine University and her Ph.D. in chemistry from Loyola University Chicago.
