This report describes various analysis conducted as part of the drywell debris transport study. A secondary objective was to explore various options available to model debris transport in the drywell, and make judgements regarding the degree of accuracy to which each phenomenon should be modeled. These analyses decomposed the problem into several components that were amenable to resolution by well-proven analytical models. The analyses specifically addressed the following phenomena that significantly impact debris transport; pressure vessel blowdown, containment thermal-hydraulics (e.g., structural wetness, flow velocities in the drywell), debris removal by various capture mechanisms and debris transport in the water pools formed on the drywell floor. The analytical tools used in the study included RELAP, MELCOR and CFD-2000.
