First excavation works for Posiva's final disposal facility to begin - YIT as contractor

Posiva Oy and YIT Construction Ltd have today signed a contract on the excavation of the first tunnels for Posiva's final disposal facility. The value of the contract is about EUR 20 million, and the estimated employment resulting from the contract, including the subcontractors, is about 100 – 125 person years.

YIT will start the excavations in December. The total length of this project phase is estimated to be about two and a half years. The contract covers, for example, the excavation of the first central tunnels as well as the vehicle access tunnels to them. Preparatory excavations are also carried out as well as rock sealing works in preparation for the raise boring of a canister shaft where the canister lift will later be installed. Excavation works for the canister receiving station at the depth of ca. 430 metres are also part of the contract.

The Radiation and Nuclear Safety Authority in Finland (STUK) has concluded in the decision it issued on November 25, 2016 that Posiva is in the position to start the construction of the final disposal facility. The decision and the contract that has now been awarded make it possible to launch the first licensed work phases of the final disposal facility as referred to in the construction licence.

- The Finnish Government granted Posiva the construction licence for the final disposal facility in November 2015. Preparations for the construction stage have proceeded well, and we are now able to start the first actual excavation work phase for the final disposal facility together with YIT, Posiva's President Janne Mokka concludes with satisfaction.

- Co-operation with Posiva has been successful already during the previous excavation contract.  When both parties share the same objectives and interests, cooperation becomes more flexible and competences can be utilised more effectively, says Ari Bergström, Vice President of rock construction at YIT.

The next construction contracts related to the construction of the final disposal facility will be awarded as the project progresses.
