Nuclear Technology

We rely on competence and experience

We offer services that cover the entire life cycle of nuclear facilities.

We plan and design, supply and install – also turnkey – process engineering equipment, systems and facilities in nuclear power plants and research facilities in Germany and abroad. We perform maintenance and inspection work and implement retrofitting measures.

We cover the full value chain (from project management to EPC projects) by building on our long presence in Germany’s nuclear industry, which started with the construction of the first NPPs and our deep knowledge of clients and site specifics through our on-site presence.

Our core expertise in nowadays mainly includes the post-operational phase, dismantling of nuclear facilities, and the design and supply of facilities for the treatment, conditioning and disposal of radioactive waste.

In major European projects like in CERN and ITER, the design work of our engineers helps to translate top research ideas into industrial scale solutions.
