Atmospheric Release Advisory Capability (ARAC) is a program that offers real-time modeling and assessment of atmospheric releases of hazardous materials, including nuclear, chemical, and biological agents. Managed by the National Atmospheric Release Advisory Center (NARAC), ARAC supports emergency response by predicting the spread and impact of pollutants, thereby aiding in decision-making to protect public health and the environment.[2]

Goals

  • Provide timely, accurate assessments of atmospheric pollutant dispersion.[3]
  • Support emergency response operations with predictive modeling.
  • Enhance preparedness and response capabilities for hazardous material incidents.

Organization

ARAC is managed by the National Atmospheric Release Advisory Center, which is part of Lawrence Livermore National Laboratory (LLNL), under the U.S. Department of Energy's National Nuclear Security Administration (NNSA). The program is led by a director and operates with a team of scientists and engineers specializing in atmospheric sciences, meteorology, and emergency response. Funding comes from DOE budgets, with additional support for specific projects or responses.

The leader of the program holds the title/position of **Director of NARAC**.

Partners

  • No specific partnerships are listed, but ARAC collaborates with various federal, state, and local agencies during emergency situations.

History

ARAC was established in 1979 following the Three Mile Island nuclear accident, highlighting the need for rapid atmospheric dispersion modeling. Originally developed by LLNL, it has since expanded its capabilities to include a wide range of hazardous materials and scenarios. Over the years, ARAC has responded to numerous incidents, including Chernobyl, Fukushima, and various chemical accidents, evolving with technological advancements in modeling and data integration.

Funding

Specific details on initial funding are not publicly specified, but ARAC is supported by DOE's budget, including allocations for emergency preparedness and response. Funding supports operational capabilities, research, and technology development.

Implementation

Implementation involves:

  • Deployment of predictive models in real-time during emergencies.
  • Integration of meteorological and geographic data for accurate simulations.
  • 24/7 availability to respond to incidents worldwide.

ARAC has no defined end date, designed to support ongoing emergency and preparedness operations.
