Abstract

In order to model the mobility of the postulated disrupted core in a core disruptive accident (CDA) of a liquid metal faster breeder reactor (LMFBR), a series of experiments was performed to simulate the behavior of a solid particle bed in a water pool against pressure transients. Numerical simulations with SIMMER-III code have been performed to verify the validity of SIMMER-III code and to check the influence of the particle jamming model and the particle viscosity model, which are adopted in the code. Comparisons between analytical results and experimental results show that SIMMER-III can well simulate the pressure transients and the particle bed axial height change in the first moment of the nitrogen gas expansion, while giving an earlier second pressure peak value than experiments. The simulation somewhat underestimates the gas volume change in the pressure vessel and the water pool. SIMMER-III results show that the particle jamming model and different assignments of velocity field have obvious influences on the particle volume fraction distribution inside the particle bed.
