Update of emergency management and rehabilitation strategies and expertise in Europe with respect to lessons learnt from the Fukushima nuclear accident
(review existing operational procedures in dealing with long lasting releases, address the cross border problematic in monitoring and safety of goods).
-
Further development of still missing functionalities in decision support systems (DSSs) and improvement of existing ones (improved source term estimation and dispersion modelling, inclusion of hydrological pathways for European water bodies).

FLEXPART ("FLEXible PARTicle dispersion model") is a Lagrangian model suitable for the simulation of a large range of atmospheric transport processes. Applications range from the dispersion of radionuclides or air pollutants, over the establishment of flow climatologies, to the analysis of Earth’s water cycle. FLEXPART also produces output suitable for inverse determination of emission sources, e.g., of greenhouse gases or volcanic ash.
flexRISK The project flexRISK studies the geographical distribution of the risk due to severe accidents in nuclear facilities, especially nuclear power plants in Europe.
