Dr. Monica C. Regalbuto - Deputy Assistant Secretary, Fuel Cycle Technologies

Dr. Monica C. Regalbuto

Dr. Regalbuto is currently the Deputy Assistant Secretary for Fuel Cycle Technologies with the Department of Energy’s Office of Nuclear Energy, whose mission promotes nuclear power as a resource capable of meeting the Nation's energy, environmental and national security needs. She previously served as a Senior Program Manager with the Office of Waste Processing with the Department of Energy’s Office of Environmental Management, supporting technical risk reduction and uncertainty in the Department’s clean-up programs. From 2003 to 2008, Dr. Regalbuto served as the head of the Process Chemistry and Engineering Department in Argonne’s Chemical Sciences and Engineering Division and managed a group of 30 researchers. Dr. Regalbuto has been a key contributor to the development of nuclear fuel cycle technologies, where she combines her experience in separations, computer simulations and proliferation resistance. She was part of the Massachusetts Institute of Technology 2010 Fuel Cycle Study Team. Dr. Regalbuto has contributed to the development of innovative energy technologies throughout her professional career. As a researcher at Argonne National Laboratory, she has made key contributions to nuclear fuel cycle technology, beginning with the TRUEX process for removing transuranic elements from aqueous acidic solutions such as those found at DOE waste sites throughout the United States followed by the development of advanced separations processes as alternatives for recycling spent fuel. She led the development of AMUSE, a computer model used by researchers to optimize processes for separating dissolved spent nuclear fuel. Under Dr. Regalbuto’s leadership, Argonne conducted highly successful process demonstrations, the CSSX process, a process for separating cesium-137 from high-level radioactive waste at DOE’s Savannah River site and the UREX+ processes, a suite of solvent extraction processes for the recovery of actinides and fission products from spent fuel. In support of her professional growth, Dr. Regalbuto joined Amoco Oil Company in December 1996 to fulfill her desire to apply her research and development expertise in an industrial setting. As a member of Amoco’s Hydroprocessing Team she provided key technical support to several refineries. Subsequently at Amoco, she was tapped to participate in a newly formed team to develop and evaluate alternative technologies for lowering the sulfur levels of gasoline. Dr. Regalbuto has authored multiple journal articles, reports, and presentations and holds six patents.
