LLW Repository
The LLW Repository site has operated safely since 1959. Its role is to ensure that Low level Waste generated in the UK is disposed of in a way that protects people and the environment.
The Repository site receives low level solid waste from a range of customers, such as the nuclear industry, the Ministry of Defence, non-nuclear industries, educational, medical and research establishments.
Site Owner
Information is presented about wastes that existed at LLW Repository 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.
