SWISS: Sustained heated metallic melt/concrete interactions with overlying water pools
Results of the test SWISS-1 and test SWISS-2 are reported. These tests examined the effects of an overlying water pool on high temperature melt interactions with concrete. In both tests, a melt of about 46 kilograms of type 304 stainless steel was formed and deposited onto a 21.6 cm diameter disk of limestone/common sand concrete. The concrete disk was retained within a cast MgO annulus. The molten steel was sustained at a power input of 1.3 to 1.7 Watts/gram by induction heating. In test SWISS-1 a water pool was formed over the melt after about 12 cm of concrete had eroded. In test SWISS-2, the water pool was formed about one minute after melt contacted the concrete and before any significant erosion of concrete could take place. In both tests the water pool was kept below the boiling point. Interactions were sustained for about 40 minutes in the two tests. Concrete erosion rates, concrete temperatures, heat fluxes to the overlying water pool, gas generation rates, and evolved gas compositions during tests SWISS-1 and SWISS-2 are reported. Aerosol generation rates are reported for test SWISS-2. 46 refs., 70 figs., 26 tabs.
