Abstract

Abstract

In this paper,the molecular dynamics method is employed to simulate the physical process under the severe accident of core melting in nuclear reactors.Based on the numerical simulation results,some mechanics mechanisms are discovered.The whole motion process of the melted metal particle from the core melting to dropping onto the low pipe sheet has been captured by current simulation results.Using molecular dynamics,a further research for the severe accident of core melting in nuclear reactor could be carried out.
