Low- and intermediate-level waste (L/ILW) is stored at nuclear power plant sites (Barsebäck, Ringhals, Oskarshamn) and at the Studsvik Research Center. A centralised underground wet storage facility (CLAB) for spent fuel has been in operation at the Oskarshamn power plant site since 1985. An expansion of this facility was completed in 2008.
A L/ILW repository has been in operation at the Forsmark power plant site (crystalline rock) since 1988. SKB (Svensk Kärnbränslehantering AB), the Swedish organisation with responsibility for managing radioactive waste, is planning to extend this facility and will submit a construction licence application in 2013.
Extensive site investigations were carried out in the crystalline formations at Oskarshamn and Forsmark between 2002 and 2007 with a view to constructing a geological repository for spent fuel. SKB proposed the Forsmark site in June 2009 and submitted a licence application in 2011. Operation is expected to begin around 2025.
The crystalline bedrock has been under investigation in the Äspö rock laboratory since 1995. There is also a Canister Laboratory at Oskarshamn, where methods for sealing and testing waste canisters are being developed. A conditioning facility for spent fuel (in copper canisters) is currently in planning, with an application for a construction licence being submitted in 2006.
