This article illustrates the development of a software named GoldEnvSim for simulation of the dispersion of radionuclides in the atmosphere. The software is written in JavaFX programming language to couple the Weather Research and Forecasting (WRF) model and the FLEXPART-WRF model. The highlight function of this software is to provide convenience for users to run a simulation workflow with a user-friendly interface. Many toolkits for post-processing and visualizing output are also incorporated to make this software more comprehensive. At this first version, GoldEnvSim is specifically designed to analyze and predict the dispersion of radioactive materials in the atmosphere, but it has potential for further development and applicable to other fields of environmental science. For demonstration, a simulation of the dispersion of the Cs-137 that is assumed to be released from the Fangchenggang nuclear power plant to whole Vietnam territory was performed. The simulation result on meteorological in comparison to the monitoring data taken from a first-class meteorological observatory was used to evaluate the accuracy of dispersion simulation result.
