【摘要】：本文以采用原型材料的OECD CCI-2实验为参考算例,在MEDICIS程序中通过合理假设、特定模型组合和敏感参数优化的方法,针对混合熔池形态下高含气量石灰石普通砂混凝土堆腔的二维堆腔侵蚀行为进行建模分析,所获得的计算结果与相应的实验结果具有较为满意的一致性,表明现有建模方法具有较好的柔性和适用性,可为核电厂MCCI事故预测提供相关的建模参考和验证基础。
[Abstract]:In this paper, the OECD CCI-2 experiment with prototype material is taken as a reference example. In the MEDICIS program, the reasonable assumption, the combination of specific models and the optimization of sensitive parameters are adopted. In this paper, the erosion behavior of two-dimensional cavities with high gas content limestone ordinary sand concrete cavities under mixed molten pool is modeled and analyzed. The calculated results are in good agreement with the corresponding experimental results. It is shown that the existing modeling methods have good flexibility and applicability, and can provide the relevant modeling reference and verification basis for the MCCI accident prediction of nuclear power plants.
