Abstract

Abstract: Regional meteorological numerical prediction and consequences evaluation for long-range transportation of radioactive contaminants are integrated into Radioactive Consequence Assessment System for Overseas Nuclear Accident (RADCON), which is used to simulate radioactive release from any point within the globe. The structure and function of RADCON is described, as well as an application analysis by assuming the Fukushima Daiichi Nuclear Power Plant nuclear accident. Results show that RADCON can truly reflect the spatial and temporal distribution of radionuclides released into the environment and provide technical support for emergency decision.

Key words: meteorological numerical prediction, trajectory, atmospheric diffusion, consequence evaluation, Fukushima Daiichi Nuclear Power Plant accident
