Modelling the dispersion of non-conservative radionuclides in tidal waters—Part 1: Conceptual and mathematical model
(Elsevier, 1996)
A 2D four-phase model to study the dispersion of non-conservative radionuclides in tidal waters, in conditions of disequilibrium for ionic exchanges, has been developed. At disequilibrium conditions, ionic exchanges cannot ...

The dispersion of 137Cs and 239,240Pu in the Rhone River plume: a numerical model
(Elsevier, 2004)
A numerical three dimensional model to simulate the transport of Cs and Pu by the Rhone River plume has been developed. The model solves the hydrodynamic equations, including baroclinic terms (that account for density ...

Numerical Modeling of the Releases of 90Sr from Fukushima to the Ocean: An Evaluation of the Source Term
(American Chemical Society, 2013)
A numerical model consisting of a 3D advection/diffusion equation, including uptake/release reactions between water and sediments described in a dynamic way, has been applied to simulate the marine releases of 90Sr from ...

Redissolution of caesium and plutonium from Irish Sea sediments: A comparison between different modelling approaches
(EDP Sciences, 2005)
Two models with different conceptual and numerical approaches have been used to simulate the dispersion of radionuclides released from Sellafield nuclear fuel reprocessing plant. The first is a long-term box-model for ...

A new comparison of marine dispersion model performances for Fukushima Dai-ichi releases in the frame of IAEA MODARIA program
(Elsevier, 2015)
A detailed intercomparison of marine dispersion models applied to the releases from Fukushima Dai-ichi nuclear power plant was carried out in the frame of MODARIA program, of the IAEA. Models were compared in such a way ...

A six-phase model to simulate the contamination by non-conservative radionuclides of sediments, soils and plants in a marsh area. Application to the Odiel marsh in southwest Spain
(Elsevier, 1997)
A numerical model to simulate the dispersion of non-conservative radionuclides in an estuarine system that surrounds a marsh area has been developed. The model includes six phases: water, two types of suspended particles ...

Marine dispersion assessment of 137Cs released from the Fukushima nuclear accident
(Elsevier, 2013)
Radionuclides were released into the atmosphere and ocean due to an accident in the Fukushima Daiichi Nuclear Power Plant (NPP) in March 2011. Numerical simulations were carried out to evaluate the distribution of 137Cs ...
