From conceptual design and optimization of new nuclear technologies like Generation IV and small modular reactors to tackling complex analytical challenges in and outside the laboratory, we’re making the impossible, possible.


Jacobs is a leader in reactor technology, conceptual design and engineering relating to new nuclear technologies including Generation IV reactors, fusion and small modular reactors (SMRs). We have a decades-long involvement in ITER, the world’s largest nuclear fusion project, where our work ranges from designing prototypes for key components to complex remote handling systems essential for reactor operations.

Our work on advanced modular and compact reactors includes designing the reactor cores and containment, steam generators, control and instrumentation, refueling systems and materials and chemistry. We have also drawn up policies for waste management, environmental management, licensing and decommissioning.

We’re leading the U.K.’s Nuclear Virtual Engineering Capability project, a government-funded research program focusing on the use of virtual engineering and high-performance computing to enhance the techniques used to design reactors and optimize their performance.

ITER aims to be the first nuclear fusion reactor to produce more energy than is required to power its plasma. If it can overcome some immense technical challenges, it’s no exaggeration to say that its success will change the world.

Jacobs leads the Momentum joint venture, which is the construction management-as-agent (CMA) contractor at ITER, responsible for coordinating the assembly of more than one million components in the ITER machine. The CMA task began in 2016 but our support to the project, based in Provence, France, goes back decades.

Innovate UK


In an innovation competition led by the U.K. Government’s Department for Business, Energy and Industrial Strategy, the Nuclear Decommissioning Authority (NDA) and Innovate U.K., we’re leading a project to design a demonstrator system for cleaning and dismantling highly radioactive rooms or ‘cells’ at Sellafield.

New navigation and materials handling solutions developed in space exploration, car production and medicine will be combined with new data and control systems and state-of-the-art robotics, creating a new system that reduces the risks of working at height, optimizes the performance of robots and uses autonomous mapping where human access is impossible.

In this project and others, as innovation integrator we’re bringing together ingenious ideas from industry and academia to define a new approach to the nuclear decommissioning challenge.

Analytics & Technology

Complex analytical challenges demand extensive capacity, capability and often a different way of tackling the issue. We operate a facility of more than 20 separate laboratories, with a multi-skilled team of technicians, graduate scientists and PhD-level specialists. Our teams provide extensive fingerprinting to enable customers to understand the radiological profile of waste streams and determine appropriate waste disposal routes.

We typically analyze over 10,000 samples every year for clients such as CERN, EDF Energy, Magnox Ltd, Dounreay Site Restoration Ltd, URENCO and Sellafield Ltd. Our work enables customers to ensure safety, meet regulatory requirements and reduce the cost of treating and disposing of waste.

LLW Repository Ltd (LLWR) operates the U.K.’s Low Level Waste Repository in West Cumbria on behalf of the Nuclear Decommissioning Authority and also oversees the management of lower activity waste throughout the country. We provide LLWR with a range of services, including hydrogeological and geological support, environmental safety case and waste characterization and assurance support.
