The Gravelines Nuclear Power Station is one of the largest nuclear power stations (the seventh largest) in the world, and the largest in Western Europe. It is located near the commune of Gravelines in Nord, France, approximately 20 km (12 mi) from Dunkerque and Calais. Its cooling water comes from the North Sea. The plant consists of 6 nuclear reactors of 900 MW each. In 2017 the plant produced 31.67 TWh of electric energy, 5.9% of French electricity production. Two reactors entered service in 1980, two in 1981, and two in 1985.
The site employs 1,680 regular employees. As of 2 August 2010, it became the first nuclear station anywhere in the world to produce over one thousand terawatt-hour of electricity.
