Objective The DISPRO cruises enabled the adjustment and validation of near-field dispersion models in the macrotidal sea by checking how representative simulated currents were in terms of direction and velocity and the short and medium term (from an hour to a week) dispersion parameters. Tritium was used as a tracer for an occasion discharge with known characteristics, in an area with intense hydrodynamic conditions (raz Blanchard off the Cotentin peninsula: maximum currents of 5 m/s). About four thousand measurements were taken in 2002 in the discharge plume of the nuclear fuel reprocessing plant at La Hague. These surveys were associated with the development of a hydrodynamic instantaneous current model by IFREMER/DEL/AO (mesh size 100 meters). Once validated, the model will make it possible to specify the short and medium term impact of chronic or accidental discharges to the marine environment. The cruise had 2 legs: from 02/11/2002. This falls under the IRSN/DISPRO.
