The Civaux Nuclear Power Plant is located in the commune of Civaux (Vienne) at the edge of Vienne River between Confolens (60 km upstream) and Chauvigny (14 km downstream), and 44 km south-east of Poitiers.
It has two operating units that were the precursors to the European Pressurized Reactor, being the "N4 stage".
Designed for a net power output of 1350 MWe per unit, power was uprated to 1360 MWe in 2010.
The Civaux plant uses ambient air and water from the Vienne River for cooling
As of 2014, 582 people work at the plant, with 2.9% women.
The cooling towers of Civaux Nuclear Power Plant are 178 metres in height, which are the highest among those of EDF's nuclear power plants.
