Topical at the construction site

Infrastructure as well as auxiliary buildings and supporting buildings valued at EUR 400–500 million will be built at the Hanhikivi 1 construction site. See the video and photo gallery below to take a quick look at what is going on at the construction site.

At the moment, approximately 190 people are working at the construction site on any given day. The Sitemanager system includes 650 companies, of which 590 are Finnish. 3,200 people have passed the site access training. 

Construction of the nuclear power plant will start once Fennovoima has been granted a construction license for the plant. The nuclear power plant consists of a reactor building, a turbine building, a control room building, and fuel buildings, among others. The highest number of people involved in the construction of the nuclear power plant at a time will be around 4,000.

Dredging and water engineering work continues off the Hanhikivi peninsula

During the next summer, dredging and water engineering work for the port and cooling water intake structure will be carried out south of the Hanhikivi peninsula. Dredging and excavation work for the cooling water discharge structures north of the peninsula will also continue.

The dredging and excavation will be performed both on the mainland and at the sea during the spring and summer. Digging work for the cooling water intake structure started on the shore at the end of April. Work carried out at the sea will start in May or June with the dredging and excavation of the port basin. Most of the dredging mass will be transported to the mainland.

The dredging and excavation will cause local noise disturbance, as well as turbidity of the water in the working areas and in their immediate vicinity. The noise and the turbidity of the water will be monitored with continuously operating meters. Fishing in the construction areas and in their immediate vicinity will not be possible during the construction work.

Work plans and risk assessments have been prepared by paying special attention to mitigation of the harm caused by the turbidity and noise to the comfort of people in the area. Spreading of the turbidity in the water to the north of the Hanhikivi peninsula will be limited with a silt curtain. The silt curtain will extend 500 meters from the shore, and its location will be marked with buoys. According to the work plan, blasting will only be performed between 7:00 am and 10:00 pm.

Dredging will take place 24/7 as long as there is no ice cover. Underwater blasting may be performed between May 20 and October 10, taking into account the spawning period of fish. The work in the water areas will be performed in compliance with the water resources management permits and environmental permits from the Regional State Administrative Agency of Northern Finland. The permit decisions include regulations on the performance of hydraulic engineering works, fishery fees, compensation to commercial fishermen, and monitoring of the environment during construction, among other issues.

The work will be performed by BMGS Eesti filial. The client is Titan-2.

Fish and Water Research Ltd will be performing test fishing in the sea area off the coast of Pyhäjoki between May and August 2020 as part of the monitoring of fishery during the Fennovoima construction project.

According to the preliminary schedule, the research fishing will start in the sea area off the coast of Pyhäjoki on week 20 and will continue until mid-August. More specific research times will depend on the prevailing conditions, such as water temperature and wind. Small amounts of fish will be caught during the test fishing, and the research will mainly involve small, newly hatched fish (fry). Click here to read the full press release (in Finnish).

The person responsible for the research project whom should be contacted for any further information is Ari Haikonen, Research Director,

Crushing at the construction site

A work stage which involves crushing stone excavated from the Hanhikivi peninsula will continue at the Hanhikivi 1 construction site in May. The contractor is Treivan Company Oy, a subcontractor of Titan-2.

There is approximately 200,000 metric tons of stone to be crushed, and it has been estimated that the crushing will take three months. The work at the crushing station is part of the excavation of rock material, and the work is subject to an environmental permit that was granted for the crushing of rock (January 15, 2016/PY-YL1/2016). By virtue of the environmental permit, crushing operations can be performed at any time of day.

Dust, noise, and vibration caused by the rock crushing will be monitored in accordance with a monitoring plan approved by the authorities. To limit the environmental impact, embankments made from crushed stone have been built around the crushing device. They will prevent noise in the sea area, the closest residential areas, and the closest holiday homes. The crushing operations do not involve any blasting. The plant supplier, RAOS Project, is in charge of continuous monitoring and the comparison of limit values. The measuring points farthest away from the crushing area are in the immediate vicinity of the closest residential areas.

The crushed stone will be used to build roads and raise the land on the Hanhikivi peninsula, for example.

Residents of the area have been informed of the crushing operations by letter. You can also opt to receive notifications about the construction site by email. To join the mailing list, please send an email to [email protected].

Movement restriction

There is a movement restriction imposed by the Ministry of the Interior for the construction site on the Hanhikivi peninsula. The restricted area covers the land areas owned by Fennovoima and the water area limited by the construction site.
The restriction has been imposed in order to secure the operations and the property at the construction site, as well as to protect the people working there. Anybody violating the restriction can be ordered to pay a fine.

Aviation prohibition at the Hanhikivi peninsula

Aviation at the Hanhikivi peninsula construction site has been prohibited by a Government Decree. The aviation prohibition area covers the fenced-in construction site area on the Hanhikivi peninsula and the surrounding land and water areas in the immediate vicinity of the construction site.
