Our Capabilities
We are a mission-driven organisation that delivers programme and project management across four domains - special nuclear material; integrated waste management; waste informed decommissioning; and design, build and operation of nuclear facilities.
Integrated Waste Management
Amentum's operation in the UK provides the safe, effective, and integrated management of radioactive waste, from generation through to disposal.
Well-Informed Decommissioning
Our waste-informed decommissioning avoids the double-handling of radioactive waste. It sees the safe and compliant removal of waste as soon as it is generated.
Special Nuclear Materials Management
From packaging and storage to transport and facility design, Amentum is experienced in the safe management of special nuclear materials.
Design, Build & Operation: Nuclear
Nuclear facilities are complex and can involve designing a repository or constructing a vault for low-level-waste, to the construction of nuclear processing facilities.
