The journey of the U.S. fuel cycle
Craig Piercycpiercy@ans.org
While most big journeys begin with a clear objective, they rarely start with an exact knowledge of the route. When commissioning the Lewis and Clark expedition in 1803, President Thomas Jefferson didn’t provide specific “turn right at the big mountain” directions to the Corps of Discovery. He gave goal-oriented instructions: explore the Missouri River, find its source, search for a transcontinental water route to the Pacific, and build scientific and cultural knowledge along the way.
Jefferson left it up to Lewis and Clark to turn his broad, geopolitically motivated guidance into gritty reality.
Similarly, U.S. nuclear policy has begun a journey toward closing the U.S. nuclear fuel cycle. There is a clear signal of support for recycling from the Trump administration, along with growing bipartisan excitement in Congress. Yet the precise path remains unclear.
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.
