The SOARCA Process

Step 1: Selecting Accident Scenarios to Model Step 3: Modeling Offsite Release of Radioactive Material Step 4: Modeling Emergency Response Step 5: Modeling Health Effects Step 2: Modeling Onsite Accident

Overall, the State-of-the-Art Reactor Consequence Analyses (SOARCA) process includes five general steps, as illustrated in the flowchart to the right. See the following pages for discussions of the methods and rationale that the project team uses in each step to determine the realistic consequences of the select severe accident scenarios:
