Nuclear News 40 under 40: The wait is over
Following the enthusiastic response from the nuclear community in 2024 for the inaugural NN 40 under 40, the Nuclear News team knew we had to take up the difficult task in 2025 of turning it into a recurring annual issue—though there was plenty of uncertainty as to how the community would receive a second iteration this year. That uncertainty was unfounded, clearly, as the tight-knit nuclear community embraced the chance to celebrate the up-and-coming generation of scientists, engineers, and policy makers who are working to grow the influence of this oft misunderstood technology.

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.
