DECOMMISSIONING & DISPOSAL | NDA STRATEGY
24 sites over the next decade. This means the reality is not everything can be done at once and the strategy makes this explicit. It reinforces prioritisation, sequencing and risk- informed decision- making, alongside proportionate approaches that match controls and methods to the hazards being managed. This is very much aligned with the Government response to the Nuclear Regulatory Taskforce review which signals a move towards smarter regulation: proportionate, focused on real risk, rooted
in evidence, and

designed to effectively protect nature and biodiversity. The NDA Group’s focus is on whole-life value – reducing
total mission cost and duration where possible – rather than short-term acceleration that creates downstream inefficiencies. Importantly, the strategy also strengthens the link between strategic direction and delivery execution. It sets the long-term direction; while business plans, mission progress reports and site programmes translate that strategy into near-term action and measurable milestones. This clear line of sight supports better decisions, greater transparency and more effective performance management across the group. This is really important when you’re dealing with the kind of timescales the NDA is facing. So, what does success look like? Broadly speaking, over
the next 25 years the NDA Group expects to have retrieved most of the radioactive waste from high-hazard facilities at the Sellafield site, repackaged a proportion of plutonium and begun to convert it into a disposable form, and delicensed most of the ex-Magnox reactor sites. For a publicly funded decommissioning organisation,
success is defined by measurable, cumulative progress that delivers outcomes. That is more high-hazard waste safely retrieved and conditioned, more redundant facilities decommissioned, more materials consolidated into safer forms, and more sites advanced toward their agreed end states. Success also means better and faster strategic decisions, stronger alignment across operating companies, and wider use of standardisation and replication to improve productivity, demonstrating value for money, and being transparent about trade-offs, risks and dependencies. Success also depends on people and capability.
Nuclear decommissioning is delivered by a highly skilled, multidisciplinary workforce – engineers, scientists, project managers, operators, safety specialists and many others. There is a strong emphasis on skills, knowledge management and leadership development, recognising

that long-term mission delivery depends on sustaining capability and knowledge across generations. It’s why ‘People’ is one of the strategy’s Critical Enablers,
which are the conditions required in order to ensure the right operating environment, capabilities and resource are in place to successfully deliver the mission. In total there are 14 enablers to the mission including
security and resilience, socio-economics, transport and logistics, and international relations. Much of the innovation delivered is developed and applied through international collaboration, working closely with international partners to share learning on legacy waste retrievals, remote operations, fuel and materials management, and decommissioning methodologies. These exchanges help accelerate learning, reduce effort duplication, and ensure the UK both benefits from, and contributes to, global best practice in nuclear clean-up. Sustainability is no longer a critical enabler in this
latest iteration of the strategy but instead is embedded throughout the strategy because it’s at the heart of everything the NDA does. It guides strategic decision making to deliver long term societal benefits while simultaneously enhancing mission performance. An example of sustainability in action came last year when more than 15,000 tonnes of crushed concrete from the demolition of the Turbine Hall at Sizewell A was made available to EDF for the construction of Sizewell C. This landmark collaboration prevented 28 tonnes of CO₂ emissions by diverting waste from landfill and significantly reduced shared costs. The NDA also has a well-established socio-economics
programme which supports the communities that host nuclear sites and invested £60m ($80m) in projects over the last five years. This investment has delivered permanent and sustainable change, attracting an additional £200m ($267m) in matched funding. These projects vary from enabling disadvantaged young people to engage with learning, skills development and delivering mental health interventions, to investing in programmes supporting regeneration, job creation and economic diversification. The ultimate aim is to free up land for reuse for whatever is deemed most beneficial for the local community, environment and wider economy. Over the years the land at NDA sites has been released to support a variety of programmes, including developing a science and innovation campus at Harwell, a business park at Winfrith and to enable renewable energy projects at Dounreay. The NDA is also exploring how its expertise, resources,
and assets can be used to support the UK’s energy security ambitions and the drive for net zero, working closely with local partners to deliver the Chapelcross masterplan for a green energy hub, for example, and also investing to develop the masterplan for a clean energy development on land adjacent to Sellafield. These developments will drive growth in the local
economy, attracting high value jobs, skills and activities benefitting the communities for generations to come. At its core, the refreshed NDA strategy is about responsible stewardship. It recognises that the NDA’s role is to deal with the past safely and responsibly, while creating the conditions for future opportunity. Decommissioning legacy nuclear sites will always be
challenging. But with clear priorities, integrated planning and sustained capability, it is a challenge that can be met – steadily, transparently and with purpose. ■
