It is seen that a simple ordinary differential equation may be sufficient to predict the mass of tracers that may be present in the Mururoa lagoon, as well as the flux from the lagoon to the Pacific. This model depends on a key parameter, namely the lagoon turnover time, which is determined from the results of a complex, three-dimensional, hydrodynamic model.
