This paper presents a new decision tree that identifies fire compartments that are screened out from further analysis according to pre-determined criteria. The paper identifies the most common fire zones and uses Computational Fluid Dynamics (CFD) model Fire Dynamics Simulator to calculate the consequences. This is a critical and very significant step in the Fire PRA. It screens out fire zones that do not affect the integrity of Fire Safe Shutdown Analysis (FSSA) cables during worst-case fire scenarios.
