The Architecture of
Civil Nuclear.
Securing the UK's 120-year nuclear decommissioning cycle and the SMR sovereign pipeline.
In 2026, the UK's civil nuclear infrastructure has crossed from policy inertia into capital execution. Sizewell C secured its Final Investment Decision in July 2025 and reached financial close on 4 November 2025, while the Rolls-Royce SMR programme has its preferred bidder, its Wylfa site, and a signed delivery contract (April 2026), with a Final Investment Decision projected around 2029. The regulatory framework is in systematic reform following the Nuclear Regulatory Taskforce's final report (November 2025), and the UK-US Atlantic Partnership for Advanced Nuclear Energy, signed September 2025, frames the international realignment away from Russian nuclear-material dependency. This runs in parallel with the NDA's decommissioning programme, estimated at around £132bn undiscounted over roughly 120 years (PAC/NDA). This dual-track environment - simultaneously decommissioning the past and commissioning the future - creates a uniquely complex procurement and regulatory architecture. Direct Intelligence provides the decision science to navigate both tracks, securing your position in the sovereign nuclear supply chain.
Identify the Accountability Friction.
SME innovators struggling to enter the NDA ecosystem due to archaic PQQ filters and the "Sovereign IP" procurement barrier.
Firms seeking to supply the SMR programme without a clear understanding of the ONR Generic Design Assessment process and timeline.
Suppliers designing strategies around a pre-decision environment when Sizewell C has its FID and financial close and the SMR site and delivery partner are confirmed, engaging the wrong procurement landscape.
Nuclear operators managing the simultaneous obligations of decommissioning legacy assets and building the hydrogen transition architecture.
Suppliers to new nuclear build facing the complexity of ONR's nuclear site licence provisions without a structured compliance pathway.
The Sector Landscape.
The 120-year lifecycle cleanup programme across Sellafield, Magnox, and legacy NDA sites.
Rolls-Royce SMR procurement, Generic Design Assessment, and the emerging gigawatt-scale build programme.
Nuclear fuel supply chain, uranium processing, and critical mineral dependencies for reactor materials.
Geological Disposal Facility (GDF) programme, radioactive waste strategy, and transport safety.
DIRECT Pillar Deployment.
Decision architecture for NDA procurement navigation and ONR regulatory authority engagement.
