Advanced Energy Solutions

We deliver safe, innovative solutions for high-risk, technically complex nuclear projects worldwide.

Nuclear offers emission-free, reliable energy to accelerate the shift away from fossil fuels and power a range of other uses including space exploration, desalination plants and data centers.

Amentum is at the forefront of conceptual design and optimization of new nuclear technologies like Generation IV, small modular and advanced reactors, and fusion power.

Amentum is sharing its multi-technology expertise, deep nuclear knowledge, skills in advanced engineering and licensing, and special technical capabilities with small modular and advanced reactor developers from the UK, USA and continental Europe.

We have a decades-long involvement in fusion power research with the UK Atomic Energy Authority and with ITER, the world’s largest nuclear fusion program, where our work ranges from designing prototypes for key components to complex remote handling systems essential for reactor operations.

Nuclear New Build

Amentum is working with clients around the world on their nuclear new build programs – helping them provide a secure, low-carbon, large-scale energy supply for the future.

Amentum is supporting a range of SMR vendors, helping to develop a new type of smart, compact, modular nuclear power plant. We’re a major contributor to ITER, the world’s largest fusion power project based in Provence, France. And we’re delivering key facilities for the United Kingdom Atomic Energy Authority’s fusion research program.

We helped design the first and second generation of the UK’s nuclear power plants and now we’re providing diverse capability for current new build programs including Hinkley Point C and Sizewell C.

As owner’s engineer and technical adviser, we have been closely involved with Poland’s new nuclear program since its inception; and we have provided the Emirates Nuclear Energy Company with program management support since the start of the Barakah program in Abu Dhabi.

Drawing on our extensive engineering design and construction management capabilities, and our global licensing, environmental and site hazard evaluation knowledge, our work with commercial and governmental clients has helped advance their civil nuclear new build programs.

Nuclear Decommissioning and Remediation

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

Amentum is a leading provider of comprehensive environmental remediation and decommissioning services, with over a century of experience delivering innovative solutions to complex environmental challenges. Our expertise encompasses the decontamination, dismantling, deactivation, and demolition of high-hazard facilities, as well as the remediation of contaminated land and water resources.

We have successfully executed projects at some of the world’s most challenging sites, including the Sellafield nuclear facility in the UK, Fukushima Daiichi Nuclear Power Plant in Japan, and U.S. Department of Energy legacy Manhattan Project sites such as Hanford, Savannah River, West Valley, and Oak Ridge Reservation.

These projects showcase Amentum’s ability to manage high-hazard, technically complex remediation efforts, utilizing advanced engineering, cutting-edge technologies, and industry-leading safety protocols. With a steadfast commitment to regulatory compliance and environmental stewardship, Amentum is uniquely equipped to tackle the world’s most challenging remediation missions.
