A Lagrangian rapid-response model for simulating the transport of radionuclides in the Arabian (or Persian) Gulf is described. The model is based on a tide model including five constituents, which was solved in advance, and baroclinic circulation was obtained from HYCOM operational ocean model. | Progress in Nuclear Energy 142 2021 103998 Contents lists available at ScienceDirect Progress in Nuclear Energy journal homepage locate pnucene APERTRACK A particle-tracking model to simulate radionuclide transport in the Arabian Persian Gulf R.

The model is based on a tide model including five constituents which was solved in Tide advance and baroclinic circulation was obtained from HYCOM operational ocean model. The radionuclide Baroclinic circulation model includes physical transport advection and diffusion radioactive decay and geochemical processes Radionuclide interactions of radionuclides between water and sediments described in a dynamic way . The model can Transport Sediment lead with instantaneous or continuous releases. Some hypothetical releases from a coastal nuclear power plant were simulated. Results show that the moment of release affects the fate of radionuclides due to the temporal variability of baroclinic currents. Also comparing results for releases of Cs and Pu it was seen how the geochemical behaviour of the radionuclide clearly affects the further radionuclide distributions. It is easy to setup the model for a particular release and it provides a fast response thus the present model is an appropriate tool to support decision-making after a nuclear accident. 1. Introduction In addition commercial and subsistence fisheries provide a living for a large sector of the coastal population Abdi et al. 2006 . The Arabian or Persian Gulf from now on APG is a shallow water The coastal environment of the APG has been exposed to various body with a mean depth of 36 m Alosairi and Pokavanich 2017 . It sources of radioactive pollution Al-Ghamdi et al. 2016 including is
