The Clab, also known as Centralt mellanlager för använt kärnbränsle (Swedish for 'Central holding storage for spent nuclear fuel') is an interim radioactive waste repository located at Oskarshamn Nuclear Power Plant about 25 km north of Oskarshamn. Clab used to be owned by Oskarshamnsverkets Kraftgrupp AB (OKG) but is now owned by Svensk Kärnbränslehantering Aktiebolag (SKB). It was opened in 1985 for the storage of spent nuclear fuel from all Swedish nuclear power plants. The fuel is stored for 30 to 40 years, in preparation for final storage.
