Chapelcross Power Station was the first nuclear power station in Scotland. Electricity generation ceased in June 2004. The site supplied strategic materials to the Ministry of Defence and was used to test fuel assemblies for later nuclear power stations.
It is now entering the defuelling phase when fuel will be progressively removed from the reactors and sent to Sellafield for treatment. An EIAD will be produced for approval by HSE/NII to enable decommissioning to begin.
