Decommissioning of Nuclear Facilities

A central focus of our decommissioning expertise lies in the dismantling of large, highly activated components in the reactor’s primary circuit - including reactor pressure vessels (RPVs), steam generators, and other thick-walled steel structures. These components pose unique challenges due to their geometry, activation levels, and radiation protection requirements.

What sets us apart is our proven ability to segment these complex components safely, efficiently, and remotely using cutting-edge techniques tailored to each project. From feasibility studies to licensing support and turnkey dismantling concepts, our solutions combine technical innovation with regulatory expertise.

NUKEM is a recognized specialist in thermal cutting technologies - a key enabler for the precise dismantling of heavily shielded or high-thickness components that mechanical methods alone cannot handle.

Our thermal cutting portfolio includes:

In combination with specialized mechanical techniques, we develop tailored cutting and handling systems for each dismantling scenario – whether dry or underwater, vertical or horizontal, shielded or accessible.

In addition to component dismantling, decommissioning projects generate significant quantities of concrete and building materials. Efficient clearance of this material is essential to reduce disposal volumes and costs.

The process of handling material on a conveyor belt inherently enables significantly more precise and faster measurement performance compared to other systems, such as drum or box measurement stations.

With FREMES (Free Release Measurement System), NUKEM offers a robust, automated system for the radiological characterization of concrete debris. FREMES ensures that large volumes of material are screened and classified with high throughput and regulatory compliance, making it a critical part of the waste management process in nuclear facility dismantling.

From planning to implementation - NUKEM delivers integrated, licensable and field-proven solutions for the safe and efficient decommissioning of nuclear facilities worldwide.
