The Nuclear Security Modeling Group provides insight, analysis, and solutions for major radiological and nuclear challenges.  Our research and development in modeling and simulations has wide ranging impact, supporting critical missions of the National Nuclear Security Administration, the Defense Threat Reduction Agency, the U.S. Department of Homeland Security, and multiple other national security agencies.

Our scientists and engineers employ modeling and simulation to confront emerging national-security threats and to perform groundbreaking research and development across multiple fronts related to radiological and nuclear challenges. Our modeling and simulation helps the nation prepare and plan for emergency response to potential nuclear or radiological disasters or attacks.  We conduct R&D that advances understanding the nuclear fuel cycle.  We improve search and assessment tactics for radioactive material.  We provide detailed estimates of potential fallout and emergency-response requirements in the event of a nuclear weapon detonation or similar catastrophe.

Our work focuses on three key areas:
