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. Water from the Vienne River is used for cooling.
As of 2014, 582 people work at the plant, with 2.9% women.
The cooling towers of Civaux Nuclear Power Plant are 200 metres in height, making them the tallest cooling towers in France.
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 a INES level-2 event.
Civaux was a proposed target in the 1998 World Cup terror plot; it was planned that Armed Islamic Group terrorists would crash a hijacked aeroplane into the plant on 15 June 1998. The plot was foiled with a mass arrest of conspirators on 26 May.
