TECHNICAL CENTER Focus on Technology

AREVA’s worldwideTechnical Center

Technical Center serves as the bridge from basic research to industrial application with main focus on basic technologies organized in the four technology lines materials, corrosion, welding – chemistry and radiochemistry – qualification of components – thermal hydraulic testing and systems and components testing.

The large variety of skills enables the Technical Center to provide long term programs or to solve in short term complicated issues with its root cause analysis teams. Customers from all over the world use e.g. the world’s largest valve test facility in Karlstein, Germany, up-to-date corrosion test loops in Le Creusot, France and the 3-axial shake table in Lynchburg.

The continuation of an OECD program with the PKL project (PKL is a 1,300 MW PWR test facility in Erlangen with 1:1 scale in height and 1:12 scale in diameter) confirms the reputation of the Technical Center. The PKL project comprises integral tests simulating conditions in the frame of beyond design accidents or shut down / outage situations. The results will allow all participating countries to further improve the safety of their plants.

The Technical Center continuously enhances its testing facilities and laboratory equipment and demonstrates the willingness to reliably support customers and the industry with its unique capabilities.
