Sellafield £3.6bn asset care framework: delivery and risk notes for project teams

First reported on New Civil Engineer
30 Second Briefing
Sellafield Ltd has selected preferred partners for a new asset care and construction procurement framework worth up to £3.6bn at its nuclear site in Cumbria, covering long-term maintenance, refurbishment and new-build works across ageing process plants and support infrastructure. The framework is expected to bundle multiple civil, structural, mechanical and electrical packages into programme-level contracts, giving suppliers greater visibility on multi-year workloads and complex shutdown interfaces. For contractors and consultants, this signals sustained demand for nuclear-grade concrete, steelwork, containment structures and specialist temporary works in one of Europe’s most regulated brownfield environments.
Technical Brief
- Asset care scope typically spans concrete remediation, structural steel replacement, pipework renewal and containment upgrades in radiological areas.
- Construction packages are expected to include new process buildings, utilities corridors, heavy-duty foundations and nuclear-grade slabs.
- Brownfield constraints at Sellafield imply complex temporary works, staged demolitions and tight working envelopes around live plants.
- Nuclear licensing will drive extensive independent design verification, QA records, welding qualifications and concrete traceability for all suppliers.
- Long-duration frameworks usually require embedded contractor teams on site, with shared planning for plant outages and access windows.
- Radiological protection requirements will affect sequencing, manning levels, material choices and construction durations for intrusive works.
Our Take
The recent RAICo1 immersive visualisation and robotics initiatives at Sellafield indicate that framework suppliers may be expected to interface with advanced digital planning and remote‑handling environments, raising the bar for BIM, simulation and constructability capabilities.
The Cleator Moor Industrial Skills Hub and Sellafield’s SME briefings in west Cumbria point to a deliberate strategy to localise parts of the supply chain, so smaller regional contractors may see more second‑tier and specialist packages flowing from this framework over time.
