• ADS granular target
• Flow process of molten material
• Moving particle semi-implicit method

In the study, the FOCUS code developed based on moving particle semi-implicit (MPS) method was used to simulate the movement and heat transfer behavior of the granular target and the flow process of molten materials, aiming at the accelerator driven subcritical system (ADS) granular target melting accident. The smaller size of the granular target will cause the larger rate of the heat transfer and melting. The conduction of granular target is the main heat transfer process.
