The Civaux Nuclear Power Plant is located in the commune of Civaux (Vienne) at the edge of Vienne River between Confolens (55 km upstream) and Chauvigny (16 km downstream), and 34 km south-east of Poitiers.

Civaux Nuclear Power Plant has two operating units that were the precursors to the European Pressurized Reactor, being the "N4 stage". Designed for a net power output of 1450 MWe per unit, power was uprated to 1495 MWe in 2003. Water from the Vienne River is used for cooling.

As of 2004, 692 people work at the plant, with 12.9% women.

On May 12, 1998 there was a leak on an elbow in a pipe of the RCS. Water leaked out at the rate of 30 cubic meters per hour. It was classified as 2 on the INES scale.
