Mark Nutt

Manager, Spent Nuclear Fuel Management

Mark Nutt is a principal nuclear engineer and manages the Spent Nuclear Fuel Management group within Argonne’s Chemical & Fuel Cycle Technologies Division.


Dr. Mark Nutt is a Principal Nuclear Engineer in the Nuclear Engineering Division at Argonne National Laboratory (ANL). Dr. Nutt has over 25 years of experience in the nuclear industry with 20 years primarily in the area of spent nuclear fuel management.  He is the National Technical Director in the U.S. Department of Energy, Office of Nuclear Energy’s (DOE-NE) Spent Fuel and Waste Disposition Program.  He is responsible for planning, coordinating, integrating, and managing a team comprised of national laboratories and contractors to support the DOE’s efforts to implement and integrated waste management system for spent nuclear fuel and high-level nuclear waste. 

Previously, Dr. Nutt served as the Deputy National Technical Director of the DOE-NE Used Fuel Disposition Research and Development campaign.  He was responsible for the management of that program, establishing research and development priorities related to the geologic disposal of nuclear waste, and performing technical work evaluating the performance of geologic disposal systems.  He has also performed research on the waste management performance attributes of advanced nuclear fuel cycles and investigated alternative disposition pathways.  He is currently serving as the chairman of the IAEA’s Technical Working Group on Nuclear Fuel Cycle Options and Spent Fuel Management and previously served as the Co-Chairman of the Waste Management Working Group under the U.S. – Japan Joint Nuclear Energy Action Plan.

Prior to joining Argonne National Laboratory in 2006, Dr. Nutt spent over nine years working on the DOE Yucca Mountain Project performing a variety of activities in support of DOE’s efforts to develop a license application for submittal to the U.S. Nuclear Regulatory Commission for authorization to construct a geologic repository.  He also has assessed the performance of facility designs for the disposal of low-level radioactive waste and spent four years as a reactor support engineer at a nuclear utility.

Dr. Nutt received his Ph.D., M.S., and B.S. in Nuclear Engineering from Iowa State University.  He has also received management and leadership education and training, including completion of the Strategic Laboratory Leadership Program at the University of Chicago Booth School of Business.
