Simulation analysis of SF6 Tracer Experiments Using an Airborne Nuclide Migration and Diffusion Model LPAN
In order to verify the effectiveness of the Lagrangian particle model LPAM in the domestic nuclear accident consequence assessment system used in coastal nuclear power plants in China,this study used atmospheric diffusion tracing experiments with relatively homogeneous diffusion factors to verify the simulation results of LPAM.The results showed that the deviation between the LPAM model simulation results and the tracer experiment results was reasonable,and the consistency was basically consistent with the performance of DIPCOT in JRODOS(European Nuclear Accident Consequence Assessment System)for tracer experiment simulation.The correlation between the four simulation results and the sampling results was also in a good performance,indicating that the simulation results of the Lagrangian particle model LPAM used in the domestic consequence assessment system of nuclear accidents were reasonable.In addition,increasing the use of corresponding physical data in subsequent research can further evaluate the effectiveness of the mode.This study can provide reference for subsequent effectiveness verification.
