Abstract
This paper analyzes the radial progression of a pool of molten reactor material that might form in a liquid-metal fast breeder reactor (LMFBR) experiencing an accident. An assessment of the thermal interaction of the molten material with its steel containment is made. The thermal response of molten UO/sub 2/ and molten UC pools was examined prior to their boilup and their dependence on steel content, porosity, and internal heat generation in the pool, as well as the heat convection rate at the outer boundary of the container, was determined. A preliminary feasibility study was presented illustrating the importance of heating rate in the pellet, radial power profile, and the heat transfer coefficient at the container outer boundary. 23 refs.
