A symbol for the atomic age when it opened in 1956, Sellafield is now preparing for the future.



When the world’s first commercial nuclear power station, Sellafield, opened in 1956 it signalled the start of a new atomic age. But as the UK’s energy mix changes, so too is Sellafield’s mission.

As the nuclear power station winds down, Sellafield’s focus shifts to environmental clean-up and waste management. RLB, with three decades of experience working at Sellafield, is proud to be playing our part. Spanning more than six square kilometres on the West Cumbrian coast, Sellafield is the size of a small town. More than 11,000 workers head to Sellafield each day, and the site operates its own bus service, armed police service, laundry, hospital and restaurants, as well as the UK’s National Nuclear Laboratory.

Our knowledge is now being harnessed in a wide range of sectors – and this is testament the skills of our people and the rigour of our work.”
