Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

Matt Dennis is a Data Scientist at the U.S. Nuclear Regulatory Commission (NRC) in the Office of Nuclear Regulatory Research. Matt joined the NRC’s Accident Analysis Branch in 2021 and leads the agency’s efforts in developing and implementing the NRC Artificial Intelligence (AI) Strategic Plan. He also leads data science and AI research and development projects, software development, and training which aid regulatory enhancements and reactor safety research. Additionally, Matt supports the development and maintenance of the MELCOR Accident Consequence Code System (MACCS) suite of codes and conducts severe accident consequence analyses.
Prior to joining the NRC, Matt held positions at Northrop Grumman and Sandia National Laboratories. As a Senior Reliability Engineer with the Reliability Analysis Laboratory at Northrop Grumman’s Mission Systems Baltimore, he supported sustainment efforts for Global Hawk, Triton and Phoenix unmanned aircraft systems. As a Senior Member of the Technical Staff in the Risk and Reliability Analysis department at Sandia National Laboratories, Matt led research and development projects supporting risk assessment and consequence analysis for new and operating nuclear reactors, as well as nuclear waste transportation. He has a B.S. and M.S. in Nuclear Engineering from the Missouri University of Science and Technology.
