Sellafield
We’re taking waste out of buildings that are as old as the site itself, dealing with the legacy of our nuclear past. We’re looking after fuel so that nuclear power stations can continue to operate, and we’re repackaging the country’s stockpile of nuclear materials.
Site Owner
Information is presented about wastes that existed at Sellafield at the stock date (1 April 2025) and were forecast to arise after this date.
For background information about this site owner, please refer to the Site Information Sheets in the 2025 UK Radioactive Waste Inventory report.
The following page presents information about radioactive wastes at the specific site selected.
Information about spent fuel and nuclear materials is presented separately in the relevant 2025 Inventory report. For official figures and essential information about how the data has been produced, always refer to the UKRWI 2025 published reports.

Waste categories
Showing results for data originating from Sellafield.
- From 1.4.2025 there is a net decrease in the reported volume of HLW. This is because accumulated Highly Active Liquor (HAL) is being conditioned, which reduces its volume. It is also because vitrified HLW is being exported to overseas customers. Thus, the volume of 1,960 m3 at 1.4.2025 is expected to fall by 814 m3, to 1,150 m3, by 2037. This is when all HAL (plus Insoluble Fission Products (IFP) residues and contaminated plant items) is expected to be conditioned.
- In addition there is 470 m3 reported volume (45.9 m3 packaged volume) from AGR fuel flasks stored at Sellafield.
- ~31,000 m3 reported volume is expected to be LLW.
