During severe light water reactor accidents like Three-Mile Island (TMI-2), the reactor core can suffer considerable damage. Of interest here are melt progression, oxidation and gas phase natural convection in the reactor core after the fuel rods suffer a significant loss of geometry. This study describes a two-dimensional porous medium model that considers the motion of three fields: vapor, melt, and solid. A base case solution is described and the effects of oxidation, melt relocation, and Fe-Zr interactions are discussed. 16 refs., 7 figs.
