The current safety case for CRBR assumes that molten fuel will penetrate long distances through steel structures (such as the gaps between subassembly can walls in the axial and radial blankets), thus removing fuel and mitigating or terminating the accident. This process involves freezing of molten core materials on flat surfaces and curved surfaces of positive and negative curvature. Phenomenological data have been obtained on the freezing of thermite simulant in pin-bundle geometries and in tubes, and on the freezing of pure UO/sub 2/ in tubes. There is reason to believe that fuel crusts will be more stable in tubes because the tube wall holds the crust in compression. On the other hand, in flat-plate geometry or on the outside of fuel pins, the crust may not be stable since it is not in compression.
