Abstract—In nuclear facilities decommissioning virtual simulation system, simulating the behavior of radioactive smoke-dust is important to the facticity of virtual scene, which is useful to reflect the distribution of radioactive nuclide and radiation dose. Based on three-dimensional numerical calculation, simulating transportation of smokedust can be realized. In this research, the corresponding mathematical model was studied firstly, and then the semi- Lagrangian method was used to solve the equations. In the process of solving equations, a splitting-approach was adopted to achieve the component equations, and then the semi-Lagrangian method was used to solve both transient and convection terms. The projection algorithm constraintbased was adopted to solve the pressure equation for incompressible fluid. This study realized a test program, which simulate the three-dimensional flow field and distribution of smoke-dust concentrations. The stable and fast solution can be achieved by using the method described in this paper. Furthermore, for improving the performance of simulation program, we implement a new program based on the programmable GPU and the new graphics API. This paper studied a kind of simulation method for simulating the smoke-dust in nuclear decommissioning process.
