“Atos Origin designs and builds EDF’s new control room simulator at Civaux nuclear power plant”

Paris, October 11, 2004

On October 1, Electricité de France (EDF) inaugurated a simulator for training control room operators at the Civaux nuclear power plant in France's Poitou-Charentes region. Project leader Atos Origin, one of the world's leading information service providers, developed the system in collaboration with equipment maker Thales Training & Simulation.

The solution comprises a full-size replica of the Civaux control room, allowing operators to practice routine operations and effective responses to emergencies.

Its unique design integrates the version of the command/control system used in the nuclear power unit to help operators meet specific engineering requirements, such as data validation, system functions upgrades and reactor behavioral analysis. Developed by Atos Origin as a solution for all nuclear power units in France's 1,450 MW N4 reactor series, the system integrates the Company's proprietary ADACSTM supervision software platform, based on the operational platform the two partners previously developed at the Chooz plant in the Ardennes.

In addition, Atos Origin is involved in the Sirocco program to design and deploy control room simulators for the country's 900 MW and 1,300 MW nuclear power plant reactors, which comprise 48 units spanning 15 sites.

“Power generation requires safe, reliable solutions,” commented Civaux plant director, Pascal Maugey. “Thanks to this simulator, which was jointly developed by Atos Origin and Thales Training & Simulation, our teams will acquire invaluable control room experience in a real-life environment enabling them to maintain a high level of competence.”

Following its acquisition of SchlumbergerSema, Atos Origin has long been a major partner to France's nuclear power program, carrying out important projects for control/command systems, providing operational assistance and supplying training simulators for the new generation of nuclear power plants.

The Civaux plant uses water from the Vienne River, whose irregular flow rate was taken into consideration when the plant was built. Like the Chooz plant, it is equipped with the latest 1,450 MW N4 reactors, whose four steam generators are each connected by a loop to the reactor. Civaux is also equipped with an Arabelle turbine. In 2003, Civaux generated 20 billion kWh (20 TWh), representing 4% of EDF's national output. The plant partially offsets northwestern France's chronic electricity production shortfalls.
