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 a...
متن کاملDispersion Coefficients of Supercritical Fluid in Fixed Beds
The axial dispersion coefficient of hexachlorobenzene in supercritical carbon dioxide is investigated in a fixed-bed packed with glass beads. The on-line chromatographic pulse-response experiment is used in order to study the dynamics of a packed column under supercritical conditions. The radial dispersion is assumed negligible because of the packed column geometry. To estimate the axial disper...
متن کاملAtmospheric dispersion model to predict the impact of gaseous pollutant in an industrial and mining cluster
Dispersion modeling approach was applied for the determination of SO2 and NO2 pollution in the ambient air. The model performance has been evaluated by comparing the measured and predicted concentrations of SO2 and NO2. This has been tested to measure the air quality and predicted incremental value of pollutant’s concentrations by using the data avail...
متن کاملQueueing performance improvement with random order dispersion
This paper analytically studies queueing performance improvement with traffic dispersion. We model sources and paths between sources and destinations as generalized binary Markov sources and discrete-time queues, respectively. We suppose that random order dispersion is employed in packet network, and we examine the effect of random order dispersion on the asymptotic tail distribution of the que...
متن کاملA GIS-based atmospheric dispersion model
Atmospheric pollution due to the use of agricultural pesticide is a major concern today, regarding both public health, sustainable agriculture and ecosystems quality monitoring. This work aims to model pesticide atmospheric dispersion and to propose an useful air pollution prediction tool, using fluid mechanics equations and open-source GIS programming capabilities. This work focuses on pestici...
