Buried Hazards, Unfinished Business - What the NDA's 2025 Progress Report Really Tells Us

1st December 2025

The Nuclear Decommissioning Authority (NDA) has released its 2025 Mission Progress Report is a slightly sprawling document chronicling one of the UK's most complex environmental undertakings. The safe dismantling of its early nuclear legacy. It's a story of radioactive waste, strategic milestones, and a timeline that stretches well into the 22nd century.

But for ordinary citizens, the real question is- what does this mean for us, our environment, and our wallets?

The Mission at a Glance
Scope: Decommissioning 17 nuclear sites across the UK, managing spent fuels, plutonium, uranium, and radioactive waste.

Some targets extend to 2125, with ongoing work to reduce uncertainty and improve inventory accuracy.

The report tracks progress across four "driving themes": Spent Fuels, Nuclear Materials, Integrated Waste Management, and Site Decommissioning & Remediation.

Progress Highlights (and Gaps)
Plutonium: 100% produced and consolidated — but 0% repacked for long-term storage, and 0% disposed.

Uranium: 100% produced, 83% consolidated, but only 4% treated and 3% reused or disposed.

Spent Magnox Fuel: All sites defueled (100%), but only 25% of legacy fuel retrieved.

Intermediate Level Waste (ILW): Just 10% treated, 16% in interim storage, and 0% disposed.

Land Release: Only 9% of land has been delicensed or relicensed for future use — with 946 hectares still pending.

These figures paint a picture of partial progress. While some milestones are complete, others remain stubbornly stalled. The NDA's strategy is clear: stabilise the most hazardous materials first, then dismantle and remediate. But the pace is glacial — and the costs, both financial and environmental, are long-term.

What Ordinary Citizens Should Know
This is a taxpayer-funded mission: Billions have been spent, and billions more will be needed. The NDA promises "maximum value for the UK taxpayer," but progress metrics suggest that value is still unfolding.

Environmental safety is the priority: The report stresses secure storage and hazard reduction, but permanent disposal solutions (like Geological Disposal Facilities) remain years away.

Jobs and land reuse are future-facing Decommissioned sites could offer new employment and regeneration opportunities — but only if remediation accelerates.

This isn't just a technical report — it's a window into how the UK handles its nuclear past. The NDA's mission is vast, slow-moving, and essential. But for families and communities near these sites, the stakes are real: land that can't be reused, waste that can’t yet be disposed, and a clean-up that spans generations.
