Leak Path Factor study at Savannah River Site

The Leak Path Factor analysis has been traditionally performed at Savannah River Site for various facilities subject to accident analysis. This paper addresses some recent work for the FB-Line building, which needed refinements to previous work that was based on a single volume approach. To model the entire building and all its simultaneous spills of contaminants in the different floors after a seismic event, a more complex multi-compartment analysis was performed using the CONTAIN 2.0 computer code. This work enabled the analysts to improve the assessment of the source term for the subsequent evaluation of the onsite and offsite doses
