The SOARCA Process

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:

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