AECOM is a global infrastructure consulting firm delivering services across the full project lifecycle, from advisory and planning to design, engineering, and construction management.
In nuclear, we support clients from early decision-making through consent to delivery readiness, reducing risk, avoiding regulatory delays, and strengthening confidence. We play a key role at program inception, shaping projects before scope and delivery strategies are fixed, enabling clear progression from first-of-a-kind developments to scalable, repeatable programs.
AECOM applies this approach across new nuclear and SMR projects, providing multidisciplinary design for site development, infrastructure, and supporting systems, alongside siting, licensing, and coordination in complex delivery environments. We also support decommissioning, waste, remediation, and regulated site infrastructure.

In fusion, we contribute to programs such as STEP and collaborate with Type One Energy and Tokamak Energy, delivering design, engineering, and expertise to advance prototype and first-generation fusion power plants and scalable infrastructure.
