Core Capabilities

Experience, passion and purpose in:

We specialise in the provision of long-term programme and project management expertise across the nuclear and defence industry.

We provide the safe, effective and integrated management of radioactive waste, from generation through to disposal.

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.

From packaging and storage to transport and facility design, Amentum is experienced in the safe management of special nuclear materials.

The design and construction of nuclear facilities is a complex process and can involve anything from designing a repository or constructing a vault for low-level-waste, to the construction of nuclear processing facilities. Amentum has the experience of operating nuclear facilities and whole sites.
