It's 50 years since the Sellafield magnox reprocessing plant began operating.
In that time, the West Cumbrian facility has reprocessed more than 50,000 tonnes of spent nuclear fuel.
It will reprocess a further 3,000 tonnes before it closes in six years' time.
The plant separates spent fuel rods into plutonium and uranium which could be reused in power station in the future.
