The Blayais nuclear power plant is a nuclear power generation center located near the town of Blaye, not far from Bourdeaux, in the heart of the Blayais marsh, in the town of Braud-et-Saint-Louis, on the edge of the Gironde. In service since 1981, it is managed by Électricité de France and produces electricity that is injected into the French electricity grid. It is cooled by water from the Gironde estuary which is pumped via underwater pipelines. As early as 1998, the annual safety review of the Blayais power station indicated the need for a 50cm rise in the dikes, but EDF deferred this raising of its protection dike. On 19 November 1999, EDF was ordered to produce a safety work schedule by a letter reminding it to order.
