Post-test examinations of the in-pile molten-pool experiments
Conference

OSTI ID:6827167
The in-pile molten pool experiments performed at SNL have been disassembled and post-test metallographic examinations have been conducted. These experiments are part of the Sandia PAHR program and have as their main objective the determination of the physical behavior, thermal characteristics and material interactions of dry debris beds. These characteristics and interactions are important for assessing the threat to containment from reactor debris. The disassembly effort and post-test examinations have revealed the extent and location of sintering and melt zones in the fuel debris and interactions with structural and candidate core retention materials. The molten pool program contains both in-pile and complementary out-of-pile tests. Five in-pile tests have been performed in this series. In these tests, either pure UO/sub 2/ or mixed UO/sub 2//steel particulate beds were fission heated to simulate decay heat power levels.
