TURC2 and 3: large scale UO/sub 2//ZrO/sub 2//Zr melt-concrete interaction experiments and analysis
Two large scale UO/sub 2//ZrO/sub 2//Zr debris-concrete experiments TURC2 and TURC3 are reported here. The experiments consisted of pouring a large quantity of molten UO/sub 2//ZrO/sub 2//Zr mixtures onto limestone-common sand concrete. The molten material was allowed to cool naturally--no internal heating was present. Data for concrete ablation, gas evolution including composition and flow rate, and aerosol generation are presented. The experimental results indicate very rapid crusting with no detectable concrete ablation. Gas reduction of H/sub 2/O and CO/sub 2/ to H/sub 2/ and CO was found to occur even with a purely oxidic (UO/sub 2//ZrO/sub 2/) melt. Aerosol concentrations varied from 62 g/m/sup 3/ to less than 1 g/m/sup 3/ in the experiments. A thermal analysis of the experiments was performed. The analysis is consistent with the result that rapid crusting with minimal concrete ablation occurs in both experiments.
