Topical from Hanhikivi 1 project: Licensing work progresses to the homestretch

During the last quarter of 2021, Fennovoima submitted more licensing material to STUK. First building permit application submitted to Pyhäjoki’s building control authority.

Licensing work at the Hanhikivi 1 nuclear power plant progressed steadily during 2021. Fennovoima submitted additional licensing material to the Radiation and Nuclear Safety Authority (STUK) for approval in late autumn.

By the end of December, Fennovoima had submitted 12.5 of the 15 batches of Preliminary Safety Analysis Report (PSAR) to STUK. Fennovoima will submit the final licensing materials to the authority during January-February.

"Our goal is to obtain construction license during 2022. Once we have submitted the last licensing materials to STUK, the necessary discussion with the authority will continue,” says Philippe Bordarier, Fennovoima’s COO.

Fennovoima submitted construction licensing material for the interim spent fuel storage

In addition to the power plant's licensing material, Fennovoima submitted construction licensing material for the Interim Spent Fuel Storage (ISFS) to the regulator for conditional approval at the end of December.

The ISFS is a part of Fennovoima's scope of works. The construction of the ISFS facility at the site will begin sometime after completing the nuclear power plant.

"The ISFS is a nuclear facility, the design of which follows the same safety principles as the nuclear power plant design. That's why we want to take into account the development of technology and the experience gained from the NPP design and construction to get the best possible solution," explains Antti Ikonen, Fennovoima's project manager for nuclear waste solutions.

Fennovoima submitted the first building permit application for a nuclear power plant

Hanhikivi 1 project is actively preparing for the construction phase of the power plant, which will begin in the summer of 2023. In 2021, earthworks started in the main pit that will be continued all 2022.

In December, Fennovoima submitted the first building permit application for a nuclear power plant to the Pyhäjoki municipality's building control authority office.

"Before the construction of a nuclear power plant can begin, we must be granted the Construction License in accordance with the Nuclear Energy Act and necessary building permits by Pyhäjoki municipality," states Karri Huusko, Fennovoima's unit manager.

The construction license verifies that the facility can be built according to Finnish nuclear safety requirements. The building permit verifies that each building fulfills Finnish building and construction requirements, which ensures, among others, Personnel and Fire Safety.

Support and auxiliary construction and infrastructure work have continued

The plant supplier RAOS Project has continued preparation works in the main pit during the autumn. The pace of excavation will accelerate in the following months as work will move towards the final foundation level, nearly 18 meters below sea level.

Support and auxiliary construction and infrastructure work have continued in the RAOS Project construction base. The total area of ​​the temporary buildings has already exceeded 100,000 square meters.

RAOS Projectin tukialueella on jatkettu tuki- ja apurakentamista sekä infratöitä. Tilapäisrakennusten yhteenlaskettu pinta-ala on ylittänyt jo 100 000 neliötä.

During the late autumn, the first permanent concrete structures, the caissons of the culvert structure, were installed in the standby seawater intake channel.

The culvert prevents sedimentation and ice from transferring into the harbor basin.

During the recent months, works on the Fennovoima's Administrative Building site moved indoors. The six-story office building will be completed in 2022.

At present, the Hanhikivi 1 site works involve about 500 people every day. The number has grown throughout the last year, even though most office workers have worked remotely due to the COVID-19.

In 2022, the number of employees at the site will increase by 100-200 people, At the peak of construction, the highest number of people involved in constructing the nuclear power plant will be around 5,500.

Due to the COVID-19 epidemic, Fennovoima is not arranging any visits to the Hanhikivi 1 site. However, the video below takes you on the flight above the Hanhikivi peninsula.
