There are several kinds of models for the environmental impact assessment of atmospheric radioactive effluents from nuclear power plant. However, few of them were developed for the purpose of review. This paper focused on comparative study on atmospheric dispersion models to recommend a set of suitable models for the reviewing environmental impact assessment of the airborne radioactive effluents under normal operation. This paper introduced the standards, guidelines and according models in relation to the airborne radioactive effluents from nuclear power plant. The program of ROULEA-2.0, C-AIRDOS, and Fluidyn PANACH were applied for numerical simulation of airborne effluents dispersion from the CAP1400 nuclear power plant under normal operation. Typical nuclide such as 85Kr was analyzed and the model of C-AIRDOS was recommended as the adaptable model for the nuclear safety review in China.
