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。
OECD CCI-2 prototype material test was used for calculation case in this paper. By means of appropriate assumption, specific model combination and sensitive parameter optimization, MEDICIS code modeling analysis was conducted on the erosion behaviours of the reactor cavity with high gas-content limestone-common-sand concrete in homogeneous melt pool configuration. The calculation results have a satisfied agreement with the related experimental results. It was shown that the present modeling method is with fair flexibility and applicability, thus could supply the accident predictions on nuclear power plant with related modeling reference and validation basis.
