Sites to visit at Olkiluoto
“Electricity from Uranium” science exhibitionThe Olkiluoto Visitor Center gives you an opportunity to take a look at the operating principle of a nuclear power plant and the path of uranium fuel as it travels from bedrock to bedrock.
The exhibition, designed by TVO and Heureka Science Center, allows you see, understand, and try out things for yourself.
The exhibition contains comprehensive information about nuclear power. You will find answers to your questions by pressing buttons, pedaling a bike, or taking a look at various information packages. You can go through the exhibition in any order you like, or use a guide leaflet. The language options are Finnish and English.
ONKALO exhibitionThe ONKALO exhibition provides information about the final disposal solution and the studies that are currently ongoing at ONKALO to verify suitability of the bedrock in Olkiluoto for the final disposal of spent nuclear fuel. You will also learn about the barriers for radioactive substances, the components and machinery to be used during the final disposal, and the future construction of the underground facilities.
In the operational waste repository (VLJ repository) research area at a depth of 60 meters, you will get an idea of the scale of the final disposal project. The exhibition is located in an area that housed, prior to the construction of the ONKALO research tunnel, a research facility where excavation of the tunnel and the drilling of the final disposal holes were studied, among other things. Due to the research carried out there, the area includes three final disposal holes and a final disposal tunnel that is a couple of meters long.
Research on the final disposal of low- and intermediate-level operational waste is still carried out in the area. At present, a joint research project of TVO and Fortum on the long-term durability of concrete is being carried out.
You will also learn about the job descriptions of the people working in the final disposal project in the ONKALO exhibition. You will be able to test your bedrock surveying skills as a geologist, make calculations as a canister developer, or try out your measuring skills as a chemist. Each visitor will also be able to experience what bentonite clay feels like and make a small concrete pellet to take home with you.
To visit the ONKALO exhibition, please book a guided group tour at Olkiluoto.
