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.

El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.
2022 ANS Annual Meeting
Dr. Kathy McCarthy, Associate Laboratory Director for the Fusion and Fission Energy and Science Directorate, joined the Oak Ridge National Laboratory (ORNL) after three years as Vice President for Science and Technology and Laboratory Director for the Canadian Nuclear Laboratories. She previously held a variety of engineering and leadership roles at Idaho National Laboratory (INL), including Director of Domestic Programs in INL’s Nuclear Science and Technology Directorate, Director of the Light Water Reactor Sustainability Program Technical Integration Office, and National Technical Director for the Systems Analysis Campaign for DOE Office of Nuclear Energy’s Fuel Cycle R&D Program.
McCarthy began her career in fusion technology with a focus on liquid metal blanket designs. She was a participant in the US DOE US-USSR Young Scientist program, which included working at the Efremov Institute in Leningrad (now St. Petersburg), Russia, the Latvian Academy of Sciences in Riga, Latvia, and the Kurchatov Institute in Moscow, Russia, and was also a Guest Scientist at the Kernforschungzentrum Karlsruhe (now the Karlsruhe Institute of Technology) in Karlsruhe, West Germany.
McCarthy earned her Ph.D. in nuclear engineering from the University of California, Los Angeles, with a major field of fusion engineering and minor fields of nuclear science and engineering, and physics – electricity and magnetism. She was inducted into the National Academy of Engineering in 2019 and has received two American Nuclear Society (ANS) presidential citations. Her awards include the 1996 ITER US Home Team Leadership Award, and the 1994 David Rose Award for Excellence in Fusion Engineering. McCarthy served on the Fusion Energy Sciences Advisory Committee from 1999 to 2013 and on the US ITER Technical Advisory Committee from 2010 to 2013 and has held numerous ANS leadership positions. She was elected as a fellow of the American Nuclear Society in 2021.
