Abstract: A microcomputer-based computer code called Waste Packager and Areal Power Density (APD) Approximator (WPA3) has been developed to compute waste package inventories and track individual assembly characteristics so that heat output at any point in time can be calculated. The waste package inventories are emplaced using a simple, serial emplacement model to estimate overall APDs and Local APDs (LAPDs) for realistic, time-phased emplacement of an actual waste stream produced by a system-level model. WPA3 can also be used to aggregate individual was packages into equivalent, lumped source terms for more realistic and robust thermal analyses.
