Assessment of atmospheric dispersion from ANPP hypothetical accident based on Fukushima accident by HYSPLIT model

The atmospheric dispersion of Materials is one of the most important ways of spreading contamination of a NPP accident. In this study, the particle paths were calculated by HYSPLIT model (both pressure and AGL form of trajectory) horizontally and vertically at 0 and 1.5 meters above ground level during 15-day periods for 23& 24 November 2006 start times. Then, the releases values of Fukushima accident in 12 & 13 March 2011 were considered as the releases of the unit 1 building, which is close to the power of Armenian Nuclear Power Plant (ANPP). According to these assumptions, the concentration of pollutants was calculated by HYSPLIT model during a 15-day period starting in 23 November 2006 at 0 and 1.5 meters above ground level. The results show that the northwestern region of Iran will be affected by the atmospheric dispersion materials from ANPP hypothetical accident in this period.
