Our current facilities

Interim storage facility for spent nuclear fuel

Spent nuclear fuel from the country's nuclear power plants is stored in an interim facility in Oskarshamn. This interim facility (Clab) has deep water basins in rock vaults 30 metres below ground level where spent fuel is stored to make it easier to handle in a final repository. Read more

Final repository for short-lived radioactive waste

The operational waste from nuclear power plants is low and intermediate-level. It consists of used protective clothing and replaced parts from the nuclear power plants. The waste is currently stored in a final repository 50 metres deep in the crystalline basement near the nuclear power plant in Forsmark. There is also much industrial, research-related and medical waste here. Read more

Specially built vessel for transportation of waste

The M/S Sigyn, an exceptionally seaworthy and safe vessel, transports radioactive waste from nuclear power plants to our facilities. While the transport containers are the primary guarantee of safety, the vessel’s hold is also specially equipped with robust cargo locks. Read more

Our laboratories

Canister Laboratory

Before fuel is transported to the final repository it must be placed in copper canisters. The Canister Laboratory is located in Oskarshamn's port area. This is where the technology for the encapsulation of spent nuclear fuel is being developed. Read more

Äspö Hard Rock Laboratory

Much of the research into future final storage of spent nuclear fuel takes place underground in the Äspö Hard Rock Laboratory (HRL), north of Oskarshamn. It is in this real environment that various technical solutions are subjected to full scale testing. Experiments are carried out at a depth of about 500 metres in collaboration with Swedish and international experts. Read more

Bentonite Laboratory

The Bentonite Laboratory is a part of the Äspö Laboratory. This is where testing is done to determine whether bentonite clay – the buffer around the capsule and the backfill for the tunnels – works in different water flows. This laboratory complements underground activities and facilitates large-scale testing of different installation methods under varying con-ditions. Unique machines and robots are also developed and tested here.
