Waste Processing

The Department of Energy’s Office of Environmental Management (EM) has a mission to clean up the contaminated soils, groundwater, buildings, and wastes generated over the past 60 years by the research, development, and production of nuclear weapons. The nation’s nuclear weapons complex generated complex radioactive and chemical wastes. Research at FIU ARC provides the necessary data and technology solutions for the engineering staff at the sites to mitigate risk associated with unique, tank-specific waste matrices, to prevent plugging of waste retrieval lines and to optimize the retrieval processes.
