The Hanhikivi 1 project

Fennovoima’s nuclear power plant project, Hanhikivi 1, is divided into phases that are preparation, procurement, licensing, construction, operation and decommissioning. 

The licensing phase began in 2014. Construction of the nuclear power plant is planned to begin in 2018, and commercial operation in 2024.

Preparation and Procurement phases

Fennovoima carried out the preparation and procurement phases of the Hanhikivi 1 nuclear power plant project in 2007–2013. The major events of the preparation phase were the first Environmental Impact Assessment (EIA) Procedure in 2008, and the granting of the decision-in-principle in 2010. During the preparation phase in 2011, the Hanhikivi headland located in the municipality of Pyhäjoki was selected as the plant site. From 2010 to 2013, Fennovoima engaged in negotiations with the plant supplier candidates. In December 2013, the negotiations concluded with the signing of a contract on the supply of an AES-2006 pressurized water reactor between Fennovoima and the Russian supplier JSC Rusatom Overseas.

Construction phase

The construction phase of the Hanhikivi 1 project has been scheduled for 2018–2023. Most of the equipment and components will be manufactured during the construction phase. At the plant site, the buildings will be constructed, and systems and components installed. The design organizations, manufacturers and contractors are responsible for the execution and organization of their own work. Fennovoima will supervise the operations, management systems and procedures of those organizations also during the construction phase. Fennovoima will pay particular attention to high safety culture during the entire project.

During the construction phase, Fennovoima will develop its organization and expertise to prepare for the operating phase. The commissioning of the nuclear power plant and preparations for the operating phase will begin at the end of the construction phase. During commissioning Fennovoima verifies the conformity of the power plant with requirements, ensures that the organization is adequate, and the procedures for operating the plant are on place. During the commissioning, the plant is officially handed over from the plant supplier to Fennovoima.

The construction phase will conclude with the start of commercial operation of the plant.

Operating phase

The commercial operation of the Hanhikivi 1 nuclear power plant, that is the operating phase, is planned to begin in 2024. During the operating phase, Fennovoima, as the licensee, will be responsible for safe operation of the nuclear power plant and that the operation complies with the requirements set for the operating phase. Key issues during the operating phase are to ensure the availability of competent personnel and the planning of the maintenance and modifications during the operation.

The planned operating life of Fennovoima’s nuclear power plant is 60 years, and Fennovoima is prepared to apply for a renewal of the operating license during the operation of the plant. When the operations of the nuclear power plant end, it will be appropriately decommissioned.
