ONKALO® Research Facility

The underground ONKALO® research facility, which extends to a depth of 450 meters, provides valuable information on the suitability of the Olkiluoto bedrock for final disposal. The bedrock is studied geologically, hydrogeologically and geochemically, among other things. The site is excavated using the traditional drill-blasting method. Research, surveys and monitoring of conditions can be conducted from ONKALO® without disturbing the construction of the disposal facility.
