摘要
近年来随着高性能计算技术的不断发展,依托先进的超级计算机和数学物理计算方法,对核反应堆开展多物理、多尺度计算成为前沿研究热点。根据反应堆堆芯多物理耦合分析需求,研究了多物理耦合算法,构建了基于中子输运、燃耗、热工子通道的堆芯多物理耦合系统,完成耦合程序开发,实现中子物理、燃耗、热工子通道的多物理耦合计算。利用压水堆组件模型与快堆模型开展输运-燃耗耦合计算测试和核-热耦合计算测试,初步验证了耦合系统功能。
In recent years,with the continuous development of high performance computing technology,relying on advanced supercomputers and mathematical physics calculation methods,multi-physical and multi-scale calculation of nuclear reactor become a hot research topic.According to the requirements of multi-physical coupling analysis of reactor core,the multi-physical coupling algorithm was studied,the multi-physical coupling system of reactor core based on neutron transport,burnup and thermal sub-channel was constructed,and the coupling program was developed.Multi-physical coupling calculation of neutron physics,burnup and thermal sub-channels was realized.The pressurized water reactor module model and the fast reactor model were used to carry out the transport-burnup coupling calculation test and the nuclear-thermal coupling calculation test,and the coupling system function is preliminarily verified.
