Dr. Mark A. Williamson is the Division Director of the Chemical and Fuel Cycle Technologies Division at Argonne National Laboratory. He leads Argonne’s nuclear chemical engineering team with research and development activities in used nuclear fuel recycling, fuel fabrication, and safeguards for next-generation nuclear energy systems. He also oversees radioisotope generation and separation systems for future application in the medical and industrial sectors.
Dr. Pereira is a Principal Chemical Engineer and Group Leader for the Process Simulations and Safeguards group in the Chemical and Fuel Cycle Technologies Division at Argonne National Laboratory. He also serves as a Relationship Manager in DDNRND (NA-22) for Argonne’s National Security Programs. Dr. Pereira has been involved on a number of projects related to the reprocessing of spent nuclear fuel and the nuclear fuel cycle.
Dr. Nicholas Condon is the Manager of the Analytical Chemistry Laboratory (ACL) in the Chemical and Fuel Cycle Technologies Division. As the ACL manager, he oversees efforts to provide a wide range of analytical chemistry support services, specializing in inorganic and radiochemical analyses. He also leads multiple projects on the development and implementation of new techniques for safeguards, forensics, and nonproliferation.
Department Manager, Pyroprocess & Materials Development
William Ebert is a chemist and manages the Pyroprocess & Waste Form Development group within Argonne’s Chemical and Fuel Cycle Technologies Division. He has more than 32 years of experience in applied research at Argonne in projects addressing the design, testing, and performance modeling of engineered high-level radioactive waste forms and spent fuel in storage and disposal environments. Ebert has developed test methods and degradation models for glass, glass/ceramic, metallic, and cermet waste forms and directly disposed oxide nuclear fuel.
Dr. Tkac received a PhD in Nuclear Chemistry from the Comenius University, Slovakia in 2003 and a M.S. in Chemistry from the Comenius University, Slovakia in 1998. He joined Argonne in October 2009 and serves as manager of the NNSA-sponsored Mo-99 program at Argonne. His work at Argonne concentrates on developing and demonstrating innovative separation and purification processes from proof of concept to full-scale operations. He has an extensive experience in speciation and optimization of separation processes relevant to actinides, lanthanides and transition metals. Most recently, he has been focusing on production and separation of medical isotopes for radio‐imaging, and radio‐therapy applications.
Department Manager, Fuel Development and Qualification
Abdellatif Yacout is a senior nuclear engineer and manages the Fuel Development and Qualification department within Argonne’s Chemical and Fuel Cycle Technologies division. His group leads work at Argonne on additive manufacturing (AM) for nuclear fuels and materials applications, which combines standard AM techniques with advanced deposition and infiltration techniques to form complex objects of different materials for both nuclear and non-nuclear applications.
