Treatment of
radioactive waste


The strictest technology and safety requirements apply to nuclear waste disposal and waste treatment facilities. With our decades of experience in the nuclear industry and our wide range of references, we are a leading supplier in the development and manufacture of plants and equipment for the treatment of radioactive waste.

Waste treatment facilities

Waste treatment facilities

Plant for the decontamination of metallic waste



We develop, plan, supply and install plants and equipment for the pre-treatment, sorting and conditioning of radioactive waste as well as for cleaning and decontamination. We focus on solving the specific problems our customers face and develop customized offers for them. With the technologies we utilize, it is possible not only to condition nuclear waste safely and efficiently, but also to significantly reduce the volume of waste – thus saving space and costs for transport and storage.

Highest-level of technology competence

We are constantly putting our comprehensive engineering expertise to the test: many of the innovative processes and methods we have developed have become firmly established in the nuclear sector and now serve as standards for waste treatment and conditioning. We reduce waste volumes using highly effective sorting, cleaning and compression processes and make the treatment, transport, storage and final disposal of radioactive waste even safer.

The cooperation with Bilfinger has been excellent due to their great expertise in handling radioactive waste. The single-source solution has helped us meet the highest safety requirements with our conditioning plant."

Florian CharnauxDirector ICEDA, EDF – DP2D

Bilfinger has extensive technological and engineering expertise in radioactive waste treatment and focuses on quality and safety. We were able to see this for ourselves during the System Design of our encapsulation plant in Oskarshamn (Sweden)."

Entsorgungswerk für Nuklearanlagen GmbH, Germany 

Conditioning plant for Konrad containers


Services: The contract awarded to Bilfinger includes the construction of the complete grouting plant, including the necessary safety equipment, to ensure that the KC is backfilled in accordance with quality standards. Solid radioactive waste is enclosed in final storage containers - so-called Konrad containers - in a cement matrix and thus conditioned for transfer to the Konrad repository.


SKB, Sweden

Encapsulation facility for the storage of spent fuel element


Services: Bilfinger has planned the design of all processes and the associated mechanical engineering equipment as well as the building areas for packaging (encapsulation) of spent fuel elements suitable for final storage. In addition, Bilfinger has coordinated the trades with the building design and provided input for the safety report and safety analysis (defense-in-depth analysis).

Conditioning plant for radioactive waste


Services: Bilfinger was responsible for the planning, design, calculation, manufacture, assembly and commissioning of the hot cells and the components required for this. The machine technology relevant to the process as well as the remote-handling components for concreting the containers were significant for the order.
