International Press Visit Day is organized a couple of times per year and includes up-to-date information sessions with the companies Teollisuuden Voima Oyj and Posiva Oy. There is also a site tour to the Olkiluoto 3 EPR site, to the repository for low- and intermediate-level operating waste and the ONKALO Research Gallery, as well as the construction site of ONKALO – the site of the final repository for spent nuclear fuel (site work permitting) and Encapsulation plant.

The visit starts at 10 a.m. and ends approximately at 5 p.m.

The dates are:

  • 16.4.2024
  • 13.5.2024



Information about the participants (nationality, name, passport number, place of residence, date & place of birth, employer's name and personal telephone number) must be provided two weeks in advance in order to confirm participation. All visitors must carry a passport or official identification card.

We reserve the right to make changes to the visit program. The possibility of visits to the Olkiluoto 3 EPR and ONKALO sites depends on the work being carried out at the site at the time.
