In recent years, research has been underway to clarify the fate of radioactive waste dumped into the Kara Sea and the Barents Sea of the Arctic Ocean. These sea areas are very narrow, shallow and located close to land.
Using the observation data (water temperature and salinity), the flow was analyzed using a hybrid box model, taking into account river flows and density structures in the seas (Wada 2002).
In this paper, using the results of flow analysis, concentration analysis is conducted on the basis of a release scenario with considerations given to nuclide decay, mixing, scavenging and interaction between undersea particles and the bottom sediment layer.
Especially, sensitivity analysis is conducted on Pu239 and Cs-137 using distribution coefficients, the concentration of suspended solids (SS) in the ocean, and the settling velocity of suspended load as parameters.
