An ongoing experimental investigation of the phenomena associated with contact between molten reactor core materials and structural concrete is described. The program uses prototypic light water reactor materials to qualitatively define aspects of the melt-concrete system which are pertinent to questions of nuclear reactor safety. Major elements of the program include exposure of calcareous and basaltic concrete to high heat fluxes on one surface and the deposition of prototypic melts into crucibles of these same concrete materials. Early results of the program are presented which demonstrate the rate and mechanism of concrete erosion under thermal attack and qualitatively describe gas evolution and concrete behavior when in contact with high-temperature melts.
