The integration of the lake and river MOIRA models into the JRODOS Hydrological Dispersion Module (HDM) modelling framework, that originally only predicted short-term radionuclide dispersion in river systems, was a key objective of the PREPARE project. Thanks to it, the capabilities of JRODOS-HDM have been increased with regard to modelling the long-term fate of radionuclides (137Cs and 90Sr) in freshwater systems and to predicting the radiation doses via aquatic exposure pathways, as well as the efficiency of countermeasures to improve the radiological impact. Validated models have been implemented and exhaustive verification tests have been performed for both lake and river scenarios.
Key words: freshwater long-term contamination / decision support / JRODOS/MOIRA
