Research visit to ONKALO, one of the very few nearly active long-term nuclear waste storage sites in the world. Onkalo is 430 metres below ground, taking advantage of Finland’s naturally stable gneiss bedrock. Final disposal is scheduled to begin in 2020 with the repository scheduled to be sealed in 2120.
ONKALO is situated on the site of the Olkiluoto power plants in the west of Finland, and I was also able to visit the Olkiluoto 3 power plant, currently under construction, to see the as yet unfinished reactor hall.
I brought a field camera on the trip. Some of the images from the 4×5.
