ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Remembering Charles E. Till
Charles E. Till
Charles E. Till, an ANS member since 1963 and Fellow since 1987, passed away on March 22 at the age of 89. He earned bachelor’s and master’s degrees from the University of Saskatchewan and a Ph.D. in nuclear engineering from Imperial College, University of London. Till initially worked for the Civilian Atomic Power Department of the Canadian General Electric Company, where he was the physicist in charge of the startup of the first prototype CANDU reactor in Canada.
Till joined Argonne National Laboratory in 1963 in the Applied Physics Division, where he worked as an experimentalist in the Fast Critical Experiments program. He then moved to additional positions of increasing responsibility, becoming division director in 1973. Under his leadership, the Applied Physics Division established itself as one of the elite reactor physics organizations in the world. Both the experimental (critical experiments and nuclear data measurements) and nuclear analysis methods work were internationally recognized. Till led Argonne’s participation in the International Nuclear Fuel Cycle Evaluation (INFCE), and he was the lead U.S. delegate to INFCE Working Group 5, Fast Breeders.
2020 ANS Virtual Winter Meeting Plenary Session Speaker
Thomas Zacharia, director of Oak Ridge National Laboratory (ORNL), guides 5,400 staff in solving scientific and technical challenges for the U.S. Department of Energy and other sponsors, managing an annual budget of $2 billion. Following a postdoctoral appointment, Thomas joined ORNL's Metals and Ceramics Division in 1989. He established and led the Materials Modeling and Simulation Group and became director of the Computer Science and Mathematics Division in 1998, Deputy Associate Laboratory Director (ALD) for High Performance Computing in 2000, and ALD for Computing and Computational Sciences in 2001. He led the creation of the Oak Ridge Leadership Computing Facility, fielding the world's fastest supercomputer, and led delivery of a petascale system for the National Science Foundation in 2008. Before becoming ORNL's director, he was Deputy for Science and Technology. Thomas holds a B.S. from the National Institute of Technology Karnataka, Surathkal, India, an M.S. from the University of Mississippi, and a Ph.D. from Clarkson University. He holds two patents and has authored more than 100 publications. He co-chairs the National Commission on Innovation and Competitiveness Frontiers established by the Council on Competitiveness. He is a Fellow of the American Welding Society, a Corresponding Member of the International Academy of Astronautics, and a Fellow of the American Association for the Advancement of Science.
