Nuclear Security Modeling Group
The Nuclear Security Modeling Group is an applied engineering group that utilizes its expertise in theory, modeling and experimentation to analyze the security implications in the production, processing, diversion and detonation of nuclear materials. The group's core area of expertise includes reactor physics and nuclear data; nuclear chemical engineering; nuclear safeguards and detection modeling; nuclear forensics and attribution; and nuclear weapons physics and fallout. The group has applied its expertise in applications such as the production of plutonium in reactors; spent fuel assay and verification; passive nuclear measurements modeling; active interrogation systems modeling; reactor physics measurements and modeling; and nuclear fallout modeling and analysis.
The group supports a variety of sponsors including other ORNL divisions and groups, the Department of Energy, the National Nuclear Security Administration, the Nuclear Regulatory Commission, the Department of Homeland Security and the International Atomic Energy Agency.
