The creation of a new system for modelling the spread of artificial radionuclides in the hydrosphere, including data assimilation for state needs during normal operation of a nuclear power station and a nuclear accident with an impact on its surroundings

A nuclear accident, whether on our territory or outside it, is a very unlikely event. However, the consequences of such an event can be very serious, so it is necessary to prepare for such scenarios. The project aims to contribute to increasing emergency preparedness for a radiation event, primarily by improving knowledge about the possibilities of modeling the spread of contamination in streams and transferring this information to the practice of the state administration (State Office for Nuclear Safety). It assesses the suitability of existing models for the purposes of modeling the spread of radionuclides in our conditions, the availability of data for these models, including their addition. The project is being solved in the years 2019–2023, the provider of support is the Technological Agency of the Czech Republic through the Theta program.
