NARAC serves as the Department of Energy/National Nuclear Security Administration (DOE/NNSA) plume modeling center, providing atmospheric transport and dispersion analyses for DOE/NNSA's operations center; regional, national and international emergency response teams; and DOE sites across the country. The center supports international organizations through the International eXchange Program (IXP), as part of DOE/NNSA's international emergency management and cooperation efforts.
DOE/NARAC serves as the primary provider of radiological/nuclear incident modeling for the Department of Homeland Security-led, multi-agency Interagency Modeling and Atmospheric Assessment Center (IMAAC). The Department of Defense (DOD)/Department of Energy's Naval Nuclear Propulsion Program (NNPP), various DoD facilities, and the National Aeronautics and Space Administration (NASA) also utilize NARAC for emergency planning and response.
