Streszczenie: During a three-month scientific internship at the Institute of Environmental Radioactivity (IER), Fukushima University, funded by the MINIATURA project (NCN), research was conducted to reconstruct the source term of the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident using transport models and measurement data. The internship focused on analyzing radionuclide releases into the atmosphere and water, modeling their environmental transport, and comparing measured radionuclide values (e.g., Cs-137, H-3) with simulated results. Enhancements to meteorological data formats were implemented to improve the model’s accuracy.

The water cycle of radionuclides in the Niida River basin was also investigated using the WRF-Hydro model. This research provided valuable insights into transport processes and emission sources following the FDNPP accident. The work involved calibrating the model for river discharge and analyzing the separation of overland and groundwater flow components based on precipitation and radionuclide measurements.

Collaboration with IER experts and access to field data facilitated detailed accident scenario reconstructions and environmental impact assessments. This research supports the development of radiological emergency management technologies in Poland, enhancing competencies in nuclear safety. The internship significantly advanced knowledge in radionuclide dispersion modeling and laid a strong foundation for future research on the impacts of nuclear accidents.
