The four reactors on the Chapelcross site have all now been defuelled, four months ahead of the original target of June 2013.
An official verification that Chapelcross is fuel free will take place over the next few months.
On completion of the inspection, the world's second oldest commercial nuclear power station will boast 'fuel-free' status for the first time in over 50 years.
A milestone in the decommissioning of Chapelcross was reached today when the last flask of spent fuel left the plant.
The container with around 150 fuel rods on board was transported by lorry from south-west Scotland to be reprocessed at Sellafield in Cumbria.
The former nuclear power plant at Chapelcross stopped producing electricity in 2004.
Its iconic cooling towers were demolished nearly six years ago, however there are still 1300 tonnes of asbestos to clear from the site, along with some intermediate level radioactive waste.
The final steps in the decommissioning process are not expected to finish until 2085.
