Dounreay is closing down.
Redundant facilities are being cleaned out and demolished, yielding large quantities of radioactive material that need to be managed safely.
Much of this material cannot be re-used and is being treated at Dounreay as radioactive waste for long-term storage or disposal.
Some of the material is nuclear fuel and could be used again, to generate electricity or to support the production of isotopes for nuclear medicine.
The Nuclear Decommissioning Authority has no plans to develop new facilities at Dounreay to re-use or recycle this fuel, so it is being packaged in a way that allows it to be returned to national stocks.
NDA decided in 2011 to move 44 tonnes of fuel to Sellafield and in February 2013 announced its intention to transfer the "exotics" to Sellafield as well.
In addition to nuclear fuel, a small amount of the radioactive waste is being removed and returned to its owners.
Dounreay recognises that the transport of radioactive material by air, sea and land raises issues of public interest about safety, security and environmental protection.
If you have concerns or questions about the removal of radioactive material from Dounreay during its closure, we're very happy to discuss these with you. We can provide more information (subject to constraints on security) and arrange to meet individuals or groups to listen to their views - click here to contact DSRL about transports.
Each year, there are some 10 million movements of radioactive material worldwide. The nuclear industry accounts for about 5 per cent of these.
This section of the website provides information about the materials leaving Dounreay, the reasons and the rigorous national and international standards we must comply with to ensure no harm is caused to people and the environment during their transport.
Transport has played an important part in the story of Dounreay, bringing nuclear materials to and from the site during four decades of research and development.
Today, as the site closes down, those materials are leaving for the last time, signalling the end of nuclear transports in the Highlands of Scotland.

Nuclear material was used at Dounreay to manufacture fuel elements used in reactors that produced isotopes for nuclear medicine, but the fabrication plant at Dounreay is among those to have been demolished.
