Abstract

Abstract

During the high-temperature reforming process, the radioactive organic nuclear waste discharged from the nuclear power plant will exist in a fluidized state. In order to obtain the detailed parameters of this process and design better operating conditions, a new numerical simulation method for reforming fluidization of radioactive waste in nuclear power plant is proposed. The numerical calculation model is designed, the governing equations of gas-solid hydrodynamics are established, and the turbulence model is established; The geometric model of radioactive organic chemical waste in nuclear power plant is established, the object geometric model is established, the grid structure is divided, and the initial boundary conditions are set. The effects of different height-diameter ratios on the radial velocity, radial solid holdup and radial gas holdup of particles are studied by numerical calculation. The calculation results show that when the height-diameter ratio is 1.0, the fluidization effect of gas-solid particles in the fluidized bed is the best.
