Posiva’s excavation contracts, Eurajoki, Finland

Posiva Oy is a specialist in nuclear waste management. Posiva is building a nuclear waste final disposal facility in Eurajoki and chose YIT to excavate the tunnels for the facility. 

The first excavation contract covered the excavation of the first central tunnels in the final disposal area and the vehicle tunnels leading to them as well as the excavation of a parking hall. 

To be completed in 2022, the second excavation contract includes the excavation of two new central tunnels and five new final disposal tunnels. 

The new tunnels will form a key part of the facility’s final disposal area and, due to their exceptionally tight quality requirements, they will be the first of their kind in the world. Building such demanding tunnel structures requires exceptional professional expertise.

“We have started the unique EKA project, which in addition to the extraction of the final disposal facility, implements the encapsulation plant in its entirety, and the systems necessary for starting the final disposal of the facilities already quarried”, says Janne Mokka, CEO of Posiva.
