Center for Used Fuel Research: Building confidence in storage and transport
Used nuclear fuel storage and transportation have reached a critical juncture.
Dozens of utilities need reliable data on how used nuclear fuel performs in dry storage casks and canisters to extend regulatory licenses at sites across the United States. Likewise, the Department of Energy expects to take ownership of the used nuclear fuel—termed “spent nuclear fuel” in the laws and regulations governing its stewardship—and transfer it to one or more federal staging facilities for management and disposition.
Meanwhile, dozens of reactor companies are testing prototypes of advanced reactors and advanced reactor fuels. Eventually, regulators and industry must also verify the safety and security of storage methods for these advanced fuel types.
To help address these challenges, the DOE established the Center for Used Fuel Research (CUFR) in January 2026 for work related to the long-term storage and transport of used nuclear fuel.
2022 ANS Winter Meeting and Technology Expo
Steven Arndt is an internationally recognized expert in the field of nuclear engineering with experience in nuclear power plant simulation, severe accident analysis and nuclear power plant instrumentation and control. In his 40 years in the nuclear industry Dr. Arndt has worked as a researcher, educator, consultant, and regulator including extensive experience in Russia and Ukraine leading the United States support programs to the states of the former Soviet Union following the Chernobyl accident and as part of the Nuclear Regulatory Commission’s (NRC’s) response to the Fukushima accident.
Dr. Arndt currently serves as a Distinguished Scientist at the Oak Ridge National Laboratory where his research involves advance reactor design readiness. Previously he spent 31 years as a senior scientist with the NRC, leading key research efforts and providing authoritative advice to NRC management and staff in the areas of digital instrumentation and control, software reliability, emergency response, cyber security and numerous other technical areas. Prior to his work at the NRC, Dr. Arndt was a Professor at the U.S. Naval Academy. Additionally, Dr. Arndt serves as an Adjunct Professor of Nuclear Engineering at the University of Tennessee. In 2012 Dr. Arndt was named the Federal Engineer of the Year by the National Society of Professional Engineers, the first nuclear engineer to ever be awarded this honor. In 2020 Dr. Arndt was awarded the “NSPE Award” the highest honor given specifically to a professional engineer.
Dr. Arndt holds a B.S. in engineering physics and a M.S. and Ph.D. in nuclear engineering all from The Ohio State University, where he was honored by the faculty of the College of Engineering in 2004 as a Distinguished Alumnus. Dr. Arndt also holds a M.S. in reliability engineering from the University of Maryland. Dr. Arndt is a Fellow of the American Society of Mechanical Engineers (ASME), the American Nuclear Society (ANS), the Association for the Advancement of Science (AAAS), the American Society for Quality (ASQ) and the National Society of Professional Engineers (NSPE).
Dr. Arndt is a registered professional engineer in Tennessee and Maryland and was appointed by the Governor of Maryland in 2006 to the Maryland Board for Professional Engineers, where he served for fifteen years (Three years as Chairman). He has served in leadership roles in a number of professional societies especially ANS. He has served as the ANS Treasurer and as a member of its Board of Directors. In June of 2022, he became the 68th President of ANS.
