Low Level Waste Repository (LLWR) Near-Surface Disposal

West Cumbrian coast near Drigg, UK · Operational (ongoing development and optimization) · Part of Nuclear Decommissioning Authority (NDA) waste management budget; Graham EDCF framework, Mott MacDonald support services

The judgement call

Account-gated at launch

The LLWR is the only facility in the UK that can receive all categories of low-level waste, making it a critical national asset for nuclear decommissioning. - Ongoing optimization and closure works, including the construction of new storage enclosures, demonstrate continuous improvement in waste management practices. - The project highlights the long-term commitment required for managing radioactive waste and the need for adaptive strategies to ensure safety and compliance.

Key engineering challenges

Ensuring long-term containment and safety of diverse low-level radioactive waste streams. - Optimizing disposal capacity and practices to meet evolving waste management needs. - Meeting stringent regulatory requirements for environmental protection and public safety over extended periods. - Developing and implementing robust monitoring and surveillance programs for the repository.
