Directorate LLNL Home ARAC's concept is to provide federal facilities and organizations throughout the country with a timely and credible centralized multi-scale dispersion modeling emergency response service. ARAC receives and processes the accident information into consequence plots which are then distributed back to the site and other agencies. An unlimited number of default accident scenarios can be stored by each facility to enhance the response time.
Credibility is achieved through a robust modeling system with known accuracy.
In addition to these supported organizations, ARAC responds to a variety of requests by other federal agencies or state agencies which request federal assistance. Using more detailed information collected during or after an accident, ARAC can perform more precise analyses in a non time-intensive mode after the event. If any measurements of the release were taken, ARAC can recreate a source term to match those values. Exercises Emergency responders perform how they practice. ARAC supports several full exercises with each site and agency each year from planning through field play including after-action reporting.
