Numerical Simulation of Dispersion of Radionuclides Released from the Fukushima NPP and the Assessment of their Nuclear Impact

Abstract:

A large number of radionuclides were discharged into oceans after the Fukushima nuclear crisis. In this paper, we employed ROMS to simulate the circulation of water around Japan. We evaluated the temporal and spatial distribution of radionuclides originated from Fukushima NPP, such as: Cs-137, Cs-134 and I-131. Then, we utilized MCNP 5 to assess the external nuclear impact of these nuclides in water and obtained the effective dose rate distribution in the coast water around Fukushima NPP.
