Results from the first three Sandia in-core molten pool experiments are reviewed. Incipient melt of a fully enriched dry bed of UO/sub 2/ was achieved in the first experiment while 30g of UO/sub 2/ was melted in the second. The melting region developed a void surrounded by a dense crust as indicated by post-test x-radiographs. In the third experiment, a steel layer was melted by an overlying layer of UO/sub 2/. Post-test x-radiographs showed no obvious penetration of the steel into the UO/sub 2/ porous matrix. Ultrasonic thermometry was used successfully to measure temperatures up to 3100/sup 0/K. The thermal histories of the in-core experiments were satisfactorily modeled using conduction theory only. Disassembly of the experiment packages will be performed shortly.
