Answer: (A) It is near the Olkiluoto Nuclear Power Plant on the west coast of Finland
Finland's ONKALO repository (the name means 'cavity' in Finnish) is on Olkiluoto island in Eurajoki municipality on the west coast, beside the Olkiluoto Nuclear Power Plant, and is built by Posiva Oy, a company owned by power producers TVO and Fortum. Spent fuel is sealed in copper and cast-iron canisters, packed in bentonite clay and placed about 400 to 450 m deep in ancient bedrock. It is the world's first deep geological repository for spent nuclear fuel to reach the operating-licence stage: the Finnish regulator STUK cleared its safety case in August 2026 and Posiva aims to begin disposal by the end of 2026. Option B mixes it up with the Svalbard Global Seed Vault (Norway), and Suomenlinna (C) is a UNESCO-listed sea fortress off Helsinki.
