National Nuclear Laboratory

What National Nuclear Laboratory does

United Kingdom National Nuclear Laboratory (UKNNL) is a UK government-owned nuclear science and technology organisation operating across the full nuclear fuel cycle, with its headquarters in Warrington and primary operational presence at Sellafield. The company was founded in 2008 and supports four focus areas — Clean Energy, Environmental Restoration, Health and Nuclear Medicine, and Security and Non-Proliferation — through four customer solution lines: Nuclear Plant Operations Support, Waste Management, Decommissioning Services, and Strategic Research and Development for government and regulators.

UKNNL's technical portfolio spans advanced nuclear materials, radiochemistry, reactor coolant testing, plutonium and uranium handling, geological disposal research, medical radionuclide production and decontamination technologies. Notable proprietary or differentiated methods include use of crushed nuclear-site concrete for strontium-90 removal from groundwater (approximately 82% removal in three months, up to 98% in 48 hours with phosphate treatment), adapted-ultrasound decontamination that cuts waste material processing from days to minutes, novel medical radionuclide production routes (including for targeted alpha therapy), and the DEPEND digital application for fuel inspection data. The organisation holds special facilities for plutonium, uranium and active material handling, and runs the SciTec conference as a sector convening forum; it publishes around 370 peer-reviewed papers and starts around 150 PhDs every five years.

The business model is fundamentally a government-funded, contract-based services and research model. UKNNL receives funding through UK government appropriations and direct contractual relationships, principally with the Nuclear Decommissioning Authority (NDA), and delivers outcomes for government through partnerships with academia (The University of Manchester, Teesside University, Clemson University) and industry (Bicycle Therapeutics, SpectronRx). Pricing is not publicly disclosed and is negotiated through government procurement processes; the revenue stream is categorised as managed services delivered under direct contracts, supporting the UK government's decommissioning, clean energy, environmental restoration, security and nuclear medicine programmes.

Core offering

National Nuclear Laboratory (UKNNL) is the UK government-owned nuclear science and technology laboratory that provides research, technical services, and innovation across the entire nuclear fuel cycle. Its core work covers nuclear plant operations support, radioactive waste management, decommissioning of legacy nuclear facilities, environmental restoration of contaminated land, clean energy R&D for next-generation reactors, medical radionuclide production for cancer treatment, and nuclear security and non-proliferation research. Services are delivered primarily to the UK Nuclear Decommissioning Authority (NDA) and other UK government departments through direct contracts.

Product overview

UK National Nuclear Laboratory (UKNNL) is a government-owned nuclear research organization that provides specialized scientific and technical services across the nuclear fuel cycle. The organization operates a platform-plus-services model consisting of four core customer solution areas (Nuclear Plant Operations Support, Waste Management, Decommissioning Services, and Strategic Research and Development) supported by four strategic focus areas (Clean Energy, Environmental Restoration, Health and Nuclear Medicine, and Security and Non-Proliferation). The portfolio includes innovative products such as the DEPEND inspection app, ultrasound decontamination technology, and novel approaches to medical isotope production. UKNNL's services span from laboratory-scale research (plutonium science, geological disposal, reactor materials testing) to operational support for existing nuclear facilities, all delivered through collaboration with academic partners, government agencies, and international institutions.
