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.
It produces uranium and plutonium which could be reused in making nuclear power in the future.
Opponents of nuclear energy have criticised the amount of discharges from the plant over the years but Sellafield Ltd, which runs the operation, said it has been "safely run for 50 years."
