To perform an integral simulation of a pool-type reactor using CFD code,a multi-physics coupled code MPC-LBE for an LBE-cooled reactor was proposed by integrating a point kinetics model and a fuel pin heat transfer model into self-developed CFD *** code verification,a code-to-code comparison was employed to validate the CFD ***,a typical BT transient benchmark on the LBE-cooled XADS reactor was selected for verification in terms of the integral or system *** on the verification results,it was demonstrated that the MPC-LBE coupled code can perform thermal-hydraulics or safety analyses for analysis for processes involved in LBE-cooled pool-type reactors.

An in-house multi-physics coupling code has been developed to solve the 3-D Navier-Stokes equations with chemical reaction to predict the unsteady turbulent combustion in solid-fuel ramjet. Firstly, the governing equations, chemical reaction models and numerical methods are illustrated in detail. Then the flow field of solid-fuel ramjet is analyzed. The results show that fuel-rich region exists near the fuel surface and oxygen-rich region exists near the central axis. Finally, the calculated regression rate is compared with those obtained with connected-pipe test. The good agreement demonstrates the predictive capability of the developed code.
