Decommissioning & Remediation

Transforming legacy assets into safe places

Sellafield 2 wideshot

Jacobs brings decades of experience to decommissioning and cleanup, drawn from our work at the world’s most challenging nuclear sites including Fukushima, Chernobyl and Hanford.

Given the nature of nuclear facilities, these legacy assets can't simply be switched off, demolished and removed.  We tackle our client’s biggest challenges and help transform contaminated sites into safe places for the environment and communities to thrive. 

We help asset owners manage the cultural and mindset shifts required to move from operations to decommissioning. We employ practical, technically and commercially innovative strategies to address the decontamination, dismantling, deactivation and demolition of high-hazard plants and sites. 

Safety case management, environmental and radiological consultancy, and health physics support go hand in hand with our core engineering capabilities, ensuring an unrelenting safety ethos. We apply strategies to minimize waste volumes requiring final disposal and we implement innovative decommissioning and decontamination processes for U.K. clients including Sellafield Ltd, Magnox Ltd and Dounreay Site Restoration Ltd. 

As a Tier 1 service provider to the U.S. Department of Energy and Atomic Energy of Canada Limited, we deliver safe and innovative solutions at complex nuclear cleanup and production sites, including the Idaho Cleanup Project, Rocky Flats Closure, Hanford Plateau Remediation and West Valley Decommissioning, just to name a few.

A pioneer for the U.K.’s nuclear industry, Sellafield supported national defense, generated electricity for nearly half a century and developed the ability to safely manage nuclear waste – delivering great benefit, while also creating a complex nuclear cleanup challenge for which there aren’t any blueprints. We’ve worked for more than 40 years to guide Sellafield’s safe decommissioning, waste management and environmental remediation.
