Transport and dispersion of tritium from the radioactive water of the Fukushima Daiichi nuclear plant. Marine Pollution Bulletin, 2021 (169), 1 p.-13 p..0025-326Xhttps://hdl.handle.net/11441/135776Japan recently announced plans to discharge over 1.2 million tons of radioactive water from the Fukushima Daiichi Nuclear Power Plant (FDNPP) into the Pacific Ocean. The contaminated water can poses a threat to marine ecosystems and human health. To estimate the impact of the plan, here, we developed a three- dimensional global model to track the transport and dispersion of tritium released from the radioactive water of the FDNPP. The pollution scenarios for four release durations (1 month, 1 year, 5 years, and 10 years) were simulated. The simulation results showed that for the release in short-duration scenarios (1 month and 1 year), the peak plume with high tritium concentration shifted with the currents and finally reached the northeastern Pacific. For the long-duration scenarios (5 years and 10 years), the peak plume of the contaminated water was confined to coastal regions east of Japan.application/pdf13 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Tritium concentration scenariosFukushima Daiichi Nuclear Power PlantThree-dimensional numerical simulationRadioactive waterinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1016/j.marpolbul.2021.112515
