Water intake at the Gravelines nuclear power plant (France)
Siphons of the hot water intake
Client: EDF - CNEPE de Tours - Scale: 1:13
Supply the LNG terminal at Dunkirk, built by EDF-CIT, with hot water discharged by the cooling circuits of Gravelines nuclear power plant. One of the services provided by Artelia was to construct a hydraulic model representing a set of two siphons and perform some appropriate tests to validate the design.
Specific aims of the scale model
- Reduce vortex phenomena at the inlets of the siphons;
- Optimize both the design and the location of these siphons;
- Assess the impact of these vortices on water levels and flows over the weirs
