High-tech for fuel assemblies, safety technology, test facilities, and Training Center

Framatome in Germany has two operational sites in Karlstein: Seligenstädter Straße and Am Kieswerk. A total of around 450 people are employed here. The solutions, systems and components from Karlstein are in use worldwide and increase the safety of nuclear power plants.

Seligenstäder Straße site

At the Seligenstäder Straße site, our company manufactures core instrumentation for boiling water and pressurized water reactors as well as diagnostic systems for new construction and modernization projects worldwide. And we project safety systems.

In addition, we operate large-scale test facilities for the testing of components under near real-life conditions. These include the world's largest test rig for large valves (GAP), the highest-capacity test loop for fuel assemblies worldwide (KATHY), the INKA integral test rig for investigating the passive safety systems of boiling water reactors on an original scale and further test rigs for component qualification.

The Training Center has provided training in different aspects of building nuclear power plants and operating them for more than 40 years. Training is not only offered to our own employees but also to customers' personnel.
