Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

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.
