The Gravelines Nuclear Power Station is a nuclear power plant located in the commune of Gravelines in Nord, France, approximately 20 km (12 mi) from Dunkerque and Calais.

As of 2 August 2010[update], it became the second nuclear station anywhere in the world to produce over one thousand terawatt-hours of electricity, following Bruce Nuclear Generating Station in Ontario, Canada, which passed that milestone in 2009.

[5] The cooling water that carries waste heat from the plant is used for aquaculture of European seabass and gilt-head breams by Acquanord.

[7][8] A major OVH datacentre is located next to the power station.
