Abstract
RASCAL 4 is a significant advancement in the U.S. Nuclear Regulatory Commission’s emergency response consequence assessment tools. RASCAL 4 includes improvements in the models and methods related to source term calculations, atmospheric dispersion and deposition, and dose calculations. Changes to the user interface will facilitate data entry, processing, and analysis. This report describes the models and methods that are included in RASCAL 4, and it describes the consequence assessment implications of changes in models and methods from RASCAL 3.
