Experimental validation and improvement of core debris/concrete interaction models
Molten core-concrete interactions are an important aspect of radioactive source-term evaluations in severe nuclear reactor accidents. At Sandia National Laboratories (SNL) six melt concrete interaction experiments have recently been conducted. An analysis of these experiments by the CORCON code has indicated discrepancies between the experimental data and the predictions. An alternate model with different heat and mass transfer phenomenology has been able to successfully predict the experimental data. The results of the alternate model suggest that the CORCON code should be modified to encompass other heat and mass transfer regimes previously thought not to exist in melt-concrete interactions. 9 refs., 22 figs., 1 tab.
