Construction contract for Posiva’s encapsulation plant awarded to Skanska

Posiva and Skanska have signed the contract agreement on the implementation phase of the construction project of the encapsulation plant for spent nuclear fuel. The total value of the contract is ca. 45 million EUR.

The construction work for the encapsulation plant to be implemented in Olkiluoto is planned to be completed in the summer of 2022.

- The encapsulation plant is built as part of Posiva’s EKA project which covers process systems for the encapsulation plant, systems required to start final disposal as well as the operating licence process, and preparations for the supply chains needed for production operation, explains Posiva’s CEO and President Janne Mokka.

- We look forward to proceeding together with Skanska from the preparatory phase of the project to the actual construction phase, and expect our good cooperation to continue also during that phase, Mr. Mokka continues.

Posiva and Skanska entered into an agreement on the preparatory phase of the project in November 2018. The encapsulation plant will be abt. 11500 square metres in floor area, and will comprise some 16000 cubic metres of concrete structures.

- The total volume of the building approximately equals that of e.g. Turku Castle,  describes Unit Manager Kari Sundelin from Skanska’s Satakunta Unit.

The spent nuclear fuel is in the encapsulation plant packed in canisters made of copper and cast iron. The canisters undergo an inspection procedure before they are deposited for final disposal in the ONKALO® facility excavated deep underground.

Skanska has long experience in nuclear facility projects and has previously executed several projects in the Olkiluoto area.
