​The Glenn T. Seaborg Institute (GTSI) at Idaho National Laboratory (INL) is committed to the development of talented researchers who pursue the chemistry and behavior of the actinide elements. GTSI-INL seeks to push the boundaries of understanding of the actinide elements through innovative and quality research. It joins a consortium of other institutes around the United States and exists as a tribute to Dr. Glenn T. Seaborg, who co-discovered multiple elements, including plutonium, and committed his life’s work to the advancement of actinide chemistry.

History

The mission of GTSI-INL, launched in 2018, is to nurture researchers and emphasize actinide work. The institute features a postdoctoral research program and community educational outreach for the purpose of developing the next generation of actinide scientists. GTSI-INL was inspired by the three other Glenn T. Seaborg institutions within the DOE complex that were active at the time, Los Alamos National Laboratory (LANL), Lawrence Livermore National Laboratory (LLNL), and the GTS Center at Lawrence Berkeley National Laboratory (LBL). The program facilitates basic actinide research to help the U.S. maintain a dominant position in the area of advanced actinide science.

About Glenn T. Seaborg

​Dr. Seaborg (1912-1999) is wid​​ely recognized as the father of the modernized Periodic Table of Elements after he suggested that the elements 89 to 103 be placed in a series below the lanthanide elements. This​​ breakthrough allowed him to predict the properties of new elements and led to his discovery of multiple new elements including plutonium, americ​​ium, and the element that bears his name, seaborgium. It cannot be overstated how much he impacted modern society. His discoveries, along with those of many other important researchers, ushered in the modern nuclear age and led to the widespread use of nuclear energy and countless radiological advancements in medical, household, and military applications. He served as an adviser to multiple U.S. presidents and organizations that shaped nuclear policy and research direction. In his later career, he became concerned with the lack of new researchers entering the field of actinide studies. He was instrumental in the establishment of the first Glenn T. Seabo​​rg Institute with the twofold mission of encouraging the development of new researchers and the advancement of the scientific understanding of the f-block elements​.

Current Postdocs at GTSI-INL

Dr. Ashini Jayasinghe

has expertise in synthesizing and characterizing lanthanide- and actinide-based compounds. She has studied uranium-based metal-organic nanotubes and actinide intermetallic materials suitable for long-term nuclear waste storage. She is interested in exploring the impact of contaminants in the speciation of actinide salts related to molten salt reactors. These contaminants can affect the rheological properties (i.e., density, viscosity, and Newtonian ideality), which inherently affects the flow and heat transfer properties of the reactor salt. ​

Amy Kynman, Glenn T. Seaborg distinguished postdoctoral researcher

Dr. Amy Kynman has expertise in synthetic f-block chemistry and catalysis. Her previous research focused on the photochemical reactivity and electronic structure studies of lanthanides and actinides. At INL, she is interested in the fundamental mechanisms underpinning the photochemistry and radiation chemistry of the actinides and how this knowledge can reduce the long-term impact of used nuclear fuel, i.e., through developing novel fission product separation techniques and new synthetic routes to useful materials.

Dr. Volodymyr Buturlim Ph.D in Condensed Matter Physics

Dr. Volodymyr Buturlim obtained his doctorate in condensed matter physics from Charles University in Prague, Czech Republic. During his doctoral studies, he investigated the electronic and magnetic properties of localized and delocalized 5f electron systems, primarily uranium-based materials, and developing theoretical models that improve our understanding of these materials for energy applications. Buturlim has extensive expertise in the synthesis and characterization of single crystalline and thin film materials. He is interested in the role of 5f electron correlations and their impact on the peculiar magnetic, heat and electron transport properties of actinide materials. His work not only deepens theoretical knowledge in condensed matter physics but paves the way for practical applications of studied materials, particularly in fields related to energy efficiency and storage.

Dr. Castro Baldivieso’s interests include the thermodynamic properties of rare earth alloys using molten salt electrolytes. She also researches the electrochemical properties and kinetic properties of Gd-Bi alloys in molten chlorides, oxide reduction of rare earth elements coupled with transition metal oxides in molten chloride salts and the electrochemical deposition of rare earths using ionic liquid and molten salts.
