Candido Pereira is a Principal Chemical Engineer and Group Leader for Process Simulation and Safeguards in the Chemical & Fuel Cycle Technologies Division at Argonne National Laboratory. He also serves as a Relationship Manager in DDN RND (NA-22) for Argonne’s National Security Programs

At Argonne, Dr. Pereira has worked on a number of projects related to the reprocessing of spent nuclear fuel and the nuclear fuel cycle. Dr. Pereira’s recent research has focused on the application of advanced simulations to process, facility, and safeguards design, including development of codes for design of solvent extraction and electrochemical processes, application of computational techniques to equipment design, support to systems analysis, and meshing of models process with advanced process monitoring in spent fuel treatment facilities.

Process development has also included pilot-scale testing with on-line spectroscopies for application to monitoring, as well as flowsheet and code validation. His group has adapted additive manufacturing and microfluidics to enhance traditional engineering design and experimental work. He has also supported Mo-99 production work related to solution cleanup and waste processing. Previously, through the Advanced Fuel Cycle Initiative and support to the Salt Waste Processing Facility, he worked on small-scale liquid-liquid extraction studies, as well as design studies ranging from small-scale process flowsheets and equipment to large-scale reprocessing facilities.

Under the Integral Fast Reactor program, he led development of a process for treating spent electrorefiner salts by ion exchange to enable its recycle, and developed a ceramic waste form for the sequestration fission product chlorides. He has also worked on the catalytic processing of gasoline and diesel fuel to generate hydrogen for fuel cells for use in transportation. He is a past-Chair of the Nuclear Engineering Division of the American Institute of Chemical Engineers. He received his Ph.D. in Chemical Engineering from the University of Pennsylvania.
