Report Title:Fukushima Accident: UNcertainty of Atmospheric dispersion modelling (FAUNA)
Activity Acronym:FAUNA
Authors:Jens Havskov Sørensen, Bjarne Amstrup, Henrik Feddersen, Ulrik Smith Korsholm, Jerzy Bartnicki, Heiko Klein, Magne Simonsen, Bent Lauritzen, Steen Cordt Hoe, Carsten Israelson, Jonas Lindgren,
Abstract:By employing the methodology developed in the NKS-B project MUD, the FAUNA project addresses assessment of the uncertainties of atmospheric dispersion model predictions of nuclear aerosols and gasses from the Fukushima Daiichi nuclear accident. The DMI meteorological numerical ensemble forecasting system involving the 21 ensemble members has been set up and applied to Japan and surroundings for the period of the main atmospheric release of radionuclides from the Fukushima Daiichi NPP in 2011. The resulting analyzed and forecast numerical weather-prediction ensemble-statistical data will be used by the Danish and Norwegian operational atmospheric dispersion models. Corresponding ensembles of atmospheric dispersion will be computed from which uncertainties of predicted radionuclide concentration and deposition patterns are derived In the present report, first results are presented.
Keywords:Fukushima Daiichi accident, nuclear emergency preparedness, atmospheric dispersion model, meteorology, uncertainty, ensemble prediction
