A high-precision analysis method for key thermal safety phenomena in a nuclear reactor based on a particle method is provided. Fine complex geometric modeling is implemented based on a multi-resolution particle method. High-order discretization of control equations is implemented using a high-order particle discretization model. Key thermal-hydraulic, mechanical deformation, chemical reaction, and neutron physics phenomena can be analyzed. An implicit and explicit hybrid solving technique and an asynchronous marching algorithm are employed. The method of the present disclosure integrates the multi-resolution particle method, high-order discretization model, advanced solving and marching techniques, and comprehensive physical-mathematical model to achieve a comprehensive, fine, and efficient analysis of key thermal safety phenomena in a nuclear reactor, avoiding mesh distortion in the mesh approach, and significantly improving the precision, stability, calculation efficiency, and robustness of the particle method.
