True Pioneers

At Sellafield, we’re true pioneers. We led the world in nuclear power production, now we’re the world’s first movers into environmental remediation. Building on our rich history, we’re striding into an era where we’ll transform the environment, local society, the regional economy and the global nuclear industry.

Covering six square kilometres, the site in West Cumbria is home to more than 200 nuclear facilities. A team of 11,000 people here work alongside our supply chain partners, to tackle a diverse portfolio of decommissioning, reprocessing, spent fuel management, nuclear waste management and nuclear material management.

Our Locations

The Sellafield site has been here since 1942. We’re proud of our history and heritage and, most importantly, the role we play in our two communities – Cumbria and Cheshire. The professional challenges are just part of what makes working for Sellafield Ltd so satisfying. In West Cumbria, we have beaches on one side and the breath-taking beauty of the Lake District on the other – it’s all sea, valleys and mountains. Our office in Risley, Warrington on the other hand is 30 minutes from Liverpool and Manchester meaning a great mix of urban attractions and rural charm. There’s something for everyone.

Sellafield site covers an area of 6 sq kilometres (about the size of six Wembley Stadiums). It is Europe’s largest nuclear site, and will become the UK’s largest construction site of any kind. Engineering, design and functional support are provided by employees based at our Risley office.
