The Nuclear Decommissioning Authority has published its strategy for cleaning up the nuclear legacy at sites such as Dounreay.
The document sets out the NDA’s approach in areas such as site restoration, spent fuels, nuclear materials and waste management.
Dounreay Site Restoration Ltd is one of the site licence companies that implement the clean-up under contract to the NDA.
Tony Fountain, NDA Chief Executive said hazard reduction was the "absolute priority”.
He added: "Our strategy provides us with a clear view of our 10 to 20 year priorities and the scope of work across our 19 sites.”
