LONDON (August 28, 2025) — AECOM, the trusted global infrastructure leader, today announced it has been appointed by Nuclear Waste Services (NWS) as framework partner for its new Integrated Design and Engineering Framework (IDEF). Under the four-year framework, AECOM will deliver design and engineering services to support front end programme delivery at the Low Level Waste Repository site in Cumbria.
AECOM will provide multidisciplinary design services associated with asset refurbishment, projects relating to general operations including demolition and remediation, and future waste management facilities, such as vaults and leachate management systems. AECOM will also work with its specialist sub-consultant partners Nuvia and Quintessa to deliver the full scope of works for the framework.
“Through this new framework, AECOM will support NWS as it continues its vital work to safely and efficiently manage the UK’s radioactive waste,” said Karen Armstrong-Telfer, nuclear practice lead for AECOM’s Energy and Environment business in the UK. “We’re excited to apply our extensive multidisciplinary expertise and deep industry knowledge to deliver innovative, timely, and safe project outcomes.”
“This partnership marks a significant step forward in our work to deliver safe, sustainable, and innovative solutions for the management of the UK’s radioactive waste,” said Mike Pigott, Director of Sites and Operations, at Nuclear Waste Services. “This work will enhance and prolong the life of critical infrastructure at the Repository site, essential for our enduring mission of making radioactive waste permanently safe sooner.
“AECOM’s expertise will be instrumental in supporting our long-term objectives, and we look forward to working collaboratively to deliver real value for the environment, our stakeholders, and future generations.”
Established in 2022, NWS brings together the expertise of LLW Repository Ltd, Radioactive Waste Management Ltd, and the NDA group’s Integrated Waste Management Programme (IWMP). It is part of the NDA group, which has a collective long-term mission to clean up nuclear decommissioning sites safely, securely, and cost-effectively.
