Forsmark Deep Geological Repository Project (KUB)

Lokalisering og anleggsoverblikk

The Forsmark Deep Geological Repository Project, known as KUB (Kärnbränsleförvaret Uppförande Berg), is Sweden’s first final repository for spent nuclear fuel. It is located within the Forsmark industrial area in Söderviken, near the Forsmark nuclear power plant in eastern Sweden. This major infrastructure project involves constructing both above-ground facilities and an extensive underground system, including a ramp approximately five kilometers long that descends to around 470-500 meters depth into the bedrock.

Komplekse underjordiske tunneler

The underground construction comprises a complex tunnel system designed to securely store spent nuclear fuel. Key components include an access tunnel leading to the first storage level, three vertical shafts intended for ventilation and elevator access, a central underground area, as well as main and transport tunnels connecting the initial repository arenas. The project covers detailed planning, design, and construction phases, reflecting its multidisciplinary and multi-phase nature. The total scope is substantial, with contract values amounting to several hundred million Swiss francs, illustrating the project's large scale and complexity.

Implenia sikrer tunnelkompetanse

Implenia has been awarded the contract by Svensk Kärnbränslehantering AB (SKB) through an Early Contractor Involvement arrangement. This collaboration brings critical technical expertise in tunnel construction and energy infrastructure, leveraging Implenia’s decades of experience with complex tunneling projects to ensure the project's safe and precise execution. The involvement of such experienced contractors underscores the project’s demands for high technical proficiency and careful management.

Planlagt byggestart 2025-2035

The project timeline begins with planning set to start in autumn or September 2025, transitioning into detailed design and construction phases, and is expected to reach completion around 2033 to 2035. This extended schedule reflects the complexity, safety requirements, and precision necessary for building a facility designed to safely contain radioactive waste for the very long term.

Sikker, miljøfokusert avfallsløsning

This deep geological repository is a critical societal infrastructure project with a strong environmental focus. Its primary benefit is to provide a safe, permanent solution for the disposal of radioactive waste, addressing long-term environmental and safety risks associated with nuclear energy. By isolating nuclear waste deep underground, the project aims to protect current and future generations from radiation hazards while fulfilling Sweden’s responsibilities in sustainable nuclear waste management.
